From 2010s, Smart contract - which was advocated in the 1990s - will gradually get the whole spotlight along with the growth of blockchain technology in general. Ethereum blockchain has become the trigger one.
With the appearance of Ethereum, some applications (Dapps - Decentralized application) have been added to crypto assets, which were merely means of remittance and payment. As a result, services and platforms originating from Ethereum such as NFT, DAO, DeFi, and DEX were born one after another, attracting the attention of investors and wealthy men from all over the world, and a lot of funds flowed in due to the future potential. A big Ethereum ecosystem is been built as this result. In addition, blockchains equipped with Smart contracts such as Polygons - Ethereum&rsquo;s second layer and Solana - the famous one as an Ethereum killer have been developed, and have grown to surpass Ethereum.
<h2 style="text-align: justify;">About Smart Contract</h2>
Firstly, let's explain the basics of smart contracts.
<h3 style="text-align: justify;">What is Smart contract?</h3>
Various economic and social activities are based on legal contracts, and all plans and actions are carried out according to the rules set by the agreements in the contract. In modern society, such as real estate transactions, construction, manufacturing, renting, buying and selling, and employment, normal organizational management, national and local governance, and the formation of various communities are impossible without contracts.
"Smart contract" means to automate all the above contracts, and the mechanism is mainly constructed by programming. Smart contracts are the concept advocated by computer scientist - Nick Szabo in 1994, but the term has been used frequently in recent years only in areas of "Blockchain". Specifically, it means that the program is automatically executed according to predetermined rules, starting from transactions on the blockchain platforms or other external information.
<h3 style="text-align: justify;">Ethereum's main protocol</h3>
Ethereum is equipped with smart contracts as a blockchain protocol for crypto assets. Bitcoin, which had been released before, also had smart contracts, but it was not worth the attention because it was beyond the scope of remittance and trading. However, in the Ethereum area, there was a "EIP (Ethereum Improvement Proposals)" where developers from all over the world solicited proposals in an open space, and with the launch of Ethereum, innovative actions were taken in rapid succession. The most important is the development of a smart contract standard called "ERC (Ethereum Request for Comments) 20" released in 2015 and the number of tokens using it. Until then, crypto assets were incompatible because they were operated according to the developers&rsquo; set standards, and in order to ensure compatibility on exchanges and wallets, additional work was required to implement a different program. In order to prevent this problems and improve convenience, many users and engineers have called for standardization, and the unified standards for smart contracts called "ERC20" was developed to meet those needs.
All tokens created using ERC20, the 20th proposed and developed in EIP, are compatible, such as Tether, Chainlink, Binancecoin (BNB), DAI (DAI), etc. Cryptocurrency assets that may achieve a break later will be born one after another. And by utilizing the crypto asset blockchain based on these ERC20 standards, various performances such as voting, crowdfunding, fee settlement, etc. can be automatically executed without the intervention of a centralized administrator.
<h2 style="text-align: justify;">ERC721's Epoch-making Role</h2>
ERC20 creates all the same Fungible tokens as currencies and stocks. For example, Mr. A's 100 JPY and Mr. B's 100 JPY have exactly the same value, and even if they are exchanged or handed over to someone else, they are still the same 100 JPY. This is "Fungible". About two years after this ERC20, the "ERC721" was developed in 2017. What remarkable about ERC721 was that it is possible to develop "non-Fungible" tokens. The smart contract installed in the ERC721 has the function of proving unique ownership by linking it with digital data such as videos, images, and music. As a result, "NFT (Non-Fungible Token)" was born.
In the first place, digital data can be easily copied by anyone by a device. No matter how good the digital art is, it can be duplicated as many times as you like, so once it was copied, it was not possible to prove which one was the original. However, the ERC721 standard smart contract made it possible. Originally, ERC721 was developed for the NFT game "CryptoKitties" launched in 2017. The epoch-making characteristic of this game is that not only can you enjoy breeding cats, but you can also buy and sell those cats as NFTs as the only character that each player has.
The birth of ERC20 was welcomed by many people involved in Ethereum and became a hot topic, but it was ERC721 that made an impact. The release request of ERC721 in 2017, NFT was suddenly becoming popular, but in 2021, when NFT art is traded at a high price, it will suddenly become a stardom. Along with this, the price of Ethereum increased about four times in just half a year, more than five times in the latter half of autumn, and at one point it soared to nearly 560,000 JPY, marking the highest price ever. Ethereum's smart contracts will allow other platforms such as DEX (Decentralized Exchange), DAO (Decentralized Autonomous Organization), and DeFi (Decentralized Finance) to trade in the absence of centralized managers for a short period of time. Moreover, they are not functioning alone, but by merging with others, and they are steadily building the Ethereum economic zone, which would be the main axis of Web3.0.
<h2 style="text-align: justify;">Differences between ERC721 and ERC1155</h2>
ERC1155 is also the standard one that is drawing attention in ERC. The features of ERC1155 are easier to understand than that of ERC721. For example, in the case of NFT games, the ERC721 smart contract had no choice but to list the NFT characters and items in the game individually on the marketplace. The Ethereum blockchain has a "scalability problem" in which the fee (gas fee) charged at each transaction is by far the highest compared to other crypto assets, and the transaction speed is delayed. With ERC721, even if you want to list all characters, you can only list them one by one, so you will have to pay a fee each time. This would increase the gas fee, which would not only impose a burden on many users, but could also be a barrier to entry. Therefore, ERC1155 was newly developed. With the ERC1155 smart contract, you can list NFTs in bulk on the marketplace, which not only speeds up transactions, but also keeps gas costs low. Furthermore, not only NFT but also several types of tokens including Fungible tokens can be sent to multiple addresses at once, ensuring unprecedented convenience. Because of these features, the ERC1155 is also known as the "multi-token standard."
When highly functional standards such as ERC20, 721, and 1155 are developed and released, ten or hundred thousand of tokens are developed and disappear in a short period of time. However, among them, crypto assets that have been highly evaluated by influential investors and wealthy people remain in the market, and we are repeating the movement to raise a large amount of funds and form new projects. In the world of crypto assets, there is no perfect system, so it is quite possible that new ERC standards with higher utility value and effectiveness will lead to further innovation. Ethereum and related services are rapidly becoming more connected to the Metaverse. Keep an eye on future trends, including the rise of crypto assets equipped with smart contracts other than Ethereum.
<h2 style="text-align: justify;">In conclusion,</h2>
Smart contracts are indispensable for building distributed networks using blockchain, which will play a leading role in Web3.0. Blockchain still has a strong image of crypto assets in the world, but in reality, it is the construction of supply chains centered on finance, manufacturing, entertainment, art, etc. There are a wide variety of usage, including examples where electronic medical records are managed by blockchain.
The potential of smart contracts is immeasurable, and we all are looking forward to the widespread penetration of an ecosystem that is safe, convenient, speedy, and functions without human intervention.
At Relipa, we are developing the blockchain related services and products. If you are thinking of DX using blockchain such as NFT, DeFi, Metaverse, please let us be your partner. Experienced engineers are looking forward to hear you.

Previously, most people couldn't understand what is NFT. However, since 2021, the recognition of this concept has increased significantly, and various digital contents have been sold in the form of NFTs.
The problem is, if you want to officially make money from your NFTs, you need to "mint" them. Even how well people know about NFT, they may be struggle when explain about &ldquo;mint&rdquo;.

<h2 id="mcetoc_1gg94fi5u2b" style="text-align: justify;">So, what is &ldquo;Mint&rdquo;?</h2>
First heard about &ldquo;Mint&rdquo;, you think straight away to &ldquo;mint&rdquo; in &ldquo;mint chocolate ice cream&rdquo;, right?
Actually, &ldquo;mint&rdquo; is the first time when tokens that adopt a smart contract and digital content are linked one-to-one and written on the blockchain to become an NFT.&nbsp;
The former definition, a smart contract, is a digital form contract, a mechanism that will be automatically executed when all its conditions and requirements are met. And the latter one, digital content, as we know, such as videos, images, game characters and music&hellip; is the target of NFTs. However, simply creating digital content cannot be called an NFT. So, the action of &ldquo;Minting&rdquo; is necessary. The ERC-721 standard (Non-fungible tokens standard) gives unique value to digital content, so NFT can be created.
NFTs can be traded by being minted on ​​dedicated marketplaces such as <a href="https://opensea.io/" target="_blank" rel="noopener">OpenSea</a>, <a href="https://rarible.com/" target="_blank" rel="noopener">Rarible</a>, and <a href="https://superrare.com/" target="_blank" rel="noopener">SuperRare</a>. Strictly speaking, the NFT issued on the marketplace is minted and still cannot be sold at this point. It's just in the form of a completed NFT, and at the time, the ownership belongs to the creator of the digital content. After that, you can start trading after setting the price of these NFTs, and this action is called "Listing".
<h2 id="mcetoc_1gg94fi5u2c" style="text-align: justify;">Mint and blockchain</h2>
The most well-known blockchain implement used in Mint is Ethereum (ETH).
It was the first blockchain adopted ERC-721, and the NFTs which were first minted and traded are using Ethereum. So, Ethereum is equivalent with NFT, and when NFT catches fire, and its price rises in an instant, it has grown to become the second most popular after Bitcoin.
However, in order to eliminate scalability such as Gas fee and time-consuming transactions, apart from Ethereum, Polygon (POL), Polkadot (DOT), Solana (SOL) are also some popular types of crypto.
New virtual currencies have also appeared one after another. Therefore, in the past, Ethereum was the only choice for NFT mints, but now you can choose from multiple options depending on the type and characteristics of the content.
<h2 id="mcetoc_1gg94fi5u2d" style="text-align: justify;">Mint and gas fee</h2>
Minting requires gas fee depends on the marketplace being used. Some marketplaces are free, while others cost thousands of dollars.
However, recently, a new term called "lazy minting" has appeared, in which NFTs are minted after they are put in the marketplace, and the gas fee is paid by the buyer after purchasing. and issuers will no longer have to incur the gas fee.
<h2 style="text-align: justify;">Minting method</h2>
<h3 id="mcetoc_1gg94fi5u2e" style="text-align: justify;">Step 1 Create content</h3>
NFTs are unique proofs of ownership in the world, so digital content must be completely original. The contents can be videos, images, or music, but please be aware that copies are not accepted as NFTs.
<h3 id="mcetoc_1gg94g88u3t" style="text-align: justify;">Step 2 Pick up Ethereum</h3>
Buy Ethereum (ETH) on domestic exchanges. In OpenSea marketplace, many NFTs are based on ETH, so ETHis required for both minting and listing.
<h3 id="mcetoc_1gg94g88u3u" style="text-align: justify;">Step 3 Choose a marketplace</h3>
Once you have created your digital content, and get enough ETH, choose a marketplace to progress the minting. There are multiple marketplaces with different features and users, but the most major and popular is OpenSea. Therefore, this article will use OpenSea as an example.
<h3 id="mcetoc_1gg94g88u3v" style="text-align: justify;">Step 4 Create a wallet</h3>
You need to have an account to mint on OpenSea. To do so, you must first create a wallet. Metamask is the most popular cryptocurrency wallet. Therefore, we recommend using Metamask. Then, install Metamask into the Google Chrome extension.
<img class="responsiveImage" style="display: block; margin-left: auto; margin-right: auto;" src="https://api.relipa.global/storage/592/screenshot_1666754306.png" alt="" />
<h3 id="mcetoc_1gg94g88u40" style="text-align: justify;">Step 5 Create an OpenSea account</h3>
After accessing the official OpenSea website and creating an account, connect to Metamask. Deposit the Ethereum purchased in Step 1 into Metamask.
<h3 id="mcetoc_1gg94g88u41" style="text-align: justify;">Step 6 Mint the NFT</h3>
Click the person icon on the top right of the OpenSea top screen and select "My Collection" to display the input screen for creating the folder necessary for minting. After entering the necessary information and creating a folder, upload the content you want to sell as NFTs and minting is completed.
<h2 id="mcetoc_1gg94fi5u2f" style="text-align: justify;">To sum up</h2>
NFTs can be minted at any time from the marketplace as long as the preparation of your own original content is good enough.
If you mint NFT, no matter how many times you buy and sell, you will be paid a fixed percentage of the sales proceeds everytime. When the value is evaluated and the price is high, it is possible to obtain a large profit even from one NFT.&nbsp;
At Relipa, NFT minting, marketplaces launching as well as others blockchain services will be done speedily by experienced engineers and great know-how. Please feel free to contact us and start your NFT right away!

"Play to Earn" -&nbsp; where you can earn money by playing games and selling in-game characters. On the NFT booming tendency from the year of 2021, it has been attracting many attention as a new way of earning money.&nbsp;
From the second half of 2021, the concept of "Move to Earn" has been emerging. So exactly, what is "Move and earn"? Let&rsquo;s find out in this blog.&nbsp;
<h2 id="mcetoc_1g8cl93hm29" style="text-align: justify;">Move to Earn</h2>
"Move to Earn" is a mechanism which helps people get crypto rewards by linking NFT (Non-Fungible Token) and movement. Specifically, as your walking or jogging, and your owning tokens will be distributed according to the speed and distance you had been moving.&nbsp;
Using GPS of smartphone, user's movement is grasped in real time, as long as the application is started, tokens are given from start to end of the moving. Tokens are bought and sold on crypto asset exchanges, so if the price rises, the assets will increase. Of course, you can sell them to get money.&nbsp;
Since "Move to Earn" itself has just been born, the number of application is still limited, and honestly, it's now still being on the first go. However, depending on future developments, the market size is expected to expand to a considerable extent.&nbsp;
Since playing such online and social games, including NFT games, is basically indoors, once you start playing, you'l have to sit for a long time. This is not healthy at all.&nbsp;
But what if the more you walk and run, the more you earn? There are double and triple merits that make you enjoy exercise and games at the same time and get rewards. This may increase the number of people who do exercises, and it may be used as a diet and anti-aging measure, and athletes may be able to enjoy monotonous training.&nbsp;
There are an unimaginable number of people in the world who enjoy walking. For those people, it will be a great deal because they can earn money just by walking because they like it. People who are worrying whether their life will last long may be able to continue walking because the profit will work and their motivation will increase if they receive a reward. The true value of "Move to Earn" is the unprecedented new way of earning money, which gives not only health but also economic benefits and allows you to enjoy the game.&nbsp;
NFTs have become quite major among investors and enthusiasts, but in general they are not yet citizens. When it comes to NFT games, the reality is that many elderly people and housewives aren't interested in them and don't even know their existance. However, with a completely different approach of health and anti-aging, there is a good chance that these kinds of games will take a hit to the people who are unfamiliar with NFTs.&nbsp;
<h2 id="mcetoc_1g8cl93hm2a" style="text-align: justify;">Two types of Move to Earn</h2>
There are two main concepts of "Move to Earn".&nbsp;
One is that people can enjoys the view that virtual and the real one are connected by converting the shoes used for walking and jogging into NFT and featuring them in exercises such as walking and running. The higher the quality of NFT shoes, the easier it is to get high points when actually exercising. If you skip it, you will get less tokens. In other words, the content of walking and jogging itself is directly linked to the reward amount.&nbsp;
Another one is a fusion of "Move to Earn" and "Play to Earn" elements. There is no change in moving your body by walking or jogging. However, the results are not linked to things that are directly related to exercise, such as shoes, as before, but are used as energy for raising and fighting characters in the game.&nbsp;
Since the character is an NFT, if the token price rises, the price will rises accordingly, and of course you can sell it on the marketplace. This point is no different from "Play to Earn". However, the decisive difference is that the starting point is not the operation of the game, but the exercise. You can't enjoy or earn money without exercising.&nbsp;
<h2 id="mcetoc_1g8cl93hm2b" style="text-align: justify;">Move to Earn - Examples</h2>
Now, let's introduce two games that you can try "Move to Earn". The former "STEPN" is the type that features exercise as mentioned earlier, and the latter "Genopets" is a type that combines "Move to Earn" and "Play to Earn".&nbsp;
<h3 id="mcetoc_1g8cl93hm2c" style="text-align: justify;"><a href="https://stepn.com/">STEPN</a>&nbsp;</h3>
"STEPN" is an NFT game built on Solana blockchain and is a pioneer of "Move to Earn". Solana is a crypto asset that can be developed by smart contracts, and it is attracting a lot of attention as an alternative to Ethereum, whose fees are rising.&nbsp;
Players can get their own token "GST" just by purchasing NFT shoes, launching the app, and walking or running. Shoes can be freely selected among 4 types: "Walker (walker = 1~6km/ h)" "Jogger (jogger = 4~10km/ h)" "Runner (runner = 8~20km/ h)" "Trainer (trainer = 1~20k / h)". The corresponding speed is fixed for each (speed in parentheses above), and if you do not walk, walk fast, or run within that range, it will not be counted as a token distribution target.&nbsp;
Once you have decided on the type of sneaker, you can further select the quality of the sneaker from 5 levels ("Common", "Uncommon", "Rare", "Epic (not implemented)", "Legendary (not implemented)"). The cheapest is "Common", but the lowest price is still around 100,000 yen. When it comes to "Rare", the price range is several million yen at a high price, so you can't buy it if you don't have enough funds. Prices for the same sneakers are changing day by day and are steadily rising in the first half of 2022.&nbsp;
After deciding the quality of the sneakers, decide the characteristics you like from the four attributes ("Efficiency", "Luck", "Comfort", and "Resilience"), which consist of parameter values. By the way, the NFT shoes are programmed to be damaged as you continue exercising and must be repaired with tokens as needed. "Resilience" If the price is high, the price will increase because the shoes are not easily damaged, but it is possible to reduce the cost for repairs. In this area, the virtual and the real are closely connected, and the "STEPN" unique "STEPN" It can be said to be a bargain and fun of "Move to Earn".&nbsp;
shoes are decided and the purchase procedure is completed, you can walk or run whenever you like and earn the travel distance. It is regulated by the type of shoes. The amount of GST granted depends on how much you can move within the speed range. GST can be exchanged for crypto assets such as SOL and USDC, and can also be sent to the wallet. These can be exchanged for yen at the exchange. If you do, you can earn cash income. It is said that you can earn about 1,000 to 30,000 yen a day, depending on the sneakers you choose and the distance you travel.&nbsp;
Furthermore, in September 2022 players will be able to rent sneakers. By lending your NFT sneakers to others, you will get 70% of the token profits for the lender and 30% for the borrowers. If the number of new entrants who can play "STEPN" even if they can't buy sneakers increases, it can be expected that the spread of "Move to Earn" will be accelerated.&nbsp;
By the way, it was about 172 JPY on January 1, 2022GST has soared to about 593 JPY as of April 1st, which shows that the attention to "STEPN", which is the forerunner of the world view of "Move to Earn", is very high.
<h3 id="mcetoc_1g8cl93hm2d" style="text-align: justify;"><a href="https://www.genopets.me/">Genopets</a>&nbsp;</h3>
"Genopets" was launched in beta following "STEPN". As of the end of March 2022, you will not be able to play this game without invitation.&nbsp;
Like "STEPN", it is operated on the Solana blockchain, and players first undergo a simple personality diagnosis and obtain an NFT pet (genopet) that suits their characteristics. In addition to walking and running, genopets can be upgraded and sold in the marketplace for exercises such as dancing and biking.&nbsp;
The big feature of "Genopets" is that the more you exercise, the more you can train and strengthen Genopets, and the more energy you can get to battle with other players. Genopets grow in four stages: "infant", "young", "adult", and "mystic".&nbsp;
With a small amount of SOL (Sorana's crypto assets), you can get started for free, which is a big advantage because it is easy to participate. For a fee, you can have a facility called "Habitat" in the game, where you can breed and breed multiple Genopets. In other words, "Genopets" can be said to be an evolutionary system that adds the element of "Play to Earn" to "Move to Earn".&nbsp;
GENE, the governance token of "Genopets", was in the 600-800 yen range from February to March 2022, but rose sharply in April of the same year, showing a sharp rise to around 2,420 yen. I am. Many prominent investors are actively investing in the Genopets project, and its popularity and expectations are reflected in the price of GENE.&nbsp;
<h2 id="mcetoc_1g8cl93hm2e" style="text-align: justify;">Move to Earn - Future potential</h2>
The possibility of the spread and development of "Move to Earn" in the future of Move to Earn is immeasurableWith the addition of outdoor elements and economic benefits to the gaming world, where indoors occupy an overwhelming share, the target number of users could be far beyond imagination.&nbsp;
At this stage, for example, in "STEPN", walking and running are the target exercises of "Move to Earn". However, technological advances have also made it possible to expand the range of exercise, such as swimming, biking and boating, and dancing, as in Genopets. Furthermore, it is not a dream to make a successful free throw in basketball, to hit the target with archery, and to derive it into various sports. In addition, if the uniforms, shoes, competition venues, etc. at that time are capitalized as NFTs, a large market will be born.&nbsp;
If this happens, the fusion of Metaverse and "Move to Earn" must be widespread. Avatar reproduces the dance performance performed in the real world in the virtual space, and the audience can watch the live from their favorite place. If the rewards for dance skills are given as crypto assets, the number of people participating in "Move to Earn" may increase dramatically. Allowing the best performers to throw money from the viewer will give them even more fun.&nbsp;
Even in baseball, it may be interesting if "Move to Earn" is performed based on the speed of pitching and the flight distance of the hit ball. Even in high school baseball, if you register as a team and reward the team itself according to the records thrown and hit by the members, it would not be a dream to use it for bats, balls, food, expeditions, etc. .. If the "Move to Earn" system can be introduced to sports for people with disabilities, it can be expected to contribute to the stability of life and the elimination of financial anxiety.&nbsp;
What is remarkable about "Move to Earn" is that it is possible to link virtual and real through blockchain as a medium. Not only have many people been under-exercised due to the Korona-ka, but the seriousness of loneliness due to social distance has also been strongly pointed out. In that sense, it can be said that the role of "Move to Earn" is very important, where players can enjoy the game and earn money while actually moving their bodies and stimulating their five senses.&nbsp;
<h2 id="mcetoc_1g8cl93hm2f" style="text-align: justify;">Summary&nbsp;</h2>
The world view of "Move to Earn" has just been born. However, it is very attractive because it has health and economic benefits, and it also has a game-like character. In fact, crypto assets related to "Move to Earn" have shown a sharp rise in 2022, and it is no exaggeration to say that it is a movement reminiscent of the return of the 2021 NFT boom. If further innovation occurs due to the fusion with Metaverse, unprecedented game changes can be considered, so keep an eye on "Move to Earn" more and more.&nbsp;

The Internet era has entered a new stage called "Web 3.0", and the attention toward the bright star - Blockchain, is increasing dramatically these days.
In fact, NFT's transaction results in 2021 is growing fabulously to 25 billion USD (~ 2.875 trillion JPY), about 250 times higher than the record of 100 million USD (~ 11.5 billion JPY) in 2020.
So, how to progress a NFT development project from the very first steps? Many people may understand the surface, but do not get the core mechanism or the development process behind.
In this blog, we will provide the ultimate guide to NFT while explaining the case of NFT game - Widiland that our company Relipa actually worked on from first stage of development to the final launching.
<h2 id="mcetoc_1g9tjvhre2kr" style="text-align: justify;">NFT Development - About</h2>
NFT development is the progress of creating NFT - related products and services, such as NFT games, NFT marketplaces, and NFT art.&nbsp;
The primary step required for developing an NFT is deciding which kind of NFT to market. Profitability is considered to be the biggest factor influences the decision step.
For example, the NFT games market size is very big, reaching 180 billion USD only in 2021. A single NFT artwork sold at a very high price of 69.35 million USD (about 7.5 billion JPY) in the same year is also an example for the high potential of NFT.
Once you've decided what to sell, it's time to start developing the Blockchain which will become the system basement as well as creating your own tokens.&nbsp;
<h2 id="mcetoc_1g9tjvhre2ks" style="text-align: justify;">How to build NFT: NFT Development Process step-by-step (From example of Relipa's NFT game - Widiland)</h2>
NFT has many different development methods depending on what kind of NFT you create. However, the general flow is similar, so through the NFT game "Widiland" launched by Relipa in 2022, let's explain in detailed how to start developing an NFT step-by-step.
"Widiland" happened in the world of 100 years in the future, when foods and energy are running down and human existence is in danger. The main theme of the game is setting the life for human-beings to survive on the new planet. In-game NFTs can be traded using the governance token - the WIDI.

<h3 id="mcetoc_1g9tjvhre2kt" style="text-align: justify;">Stage 1: Tokenomics and NFT Design</h3>
The base of NFT project includes its purpose, future plans, the kind of finance and token to drive the business, and Tokenomic, which shows the way to maintain the supply - demand balance and the value of tokens.
In the case of "Widiland", the value is set to "400 million WIDI". A part from this,&nbsp; self-financing accounts for 21%, IDO for 2.5%, non-trading private sale for 9.5%, seed-partners for 6%, rewards by staking method make up for 28%, Metaverse fund for 15%. By the way, the token price is 0.04 USD for IDO, 0.025 USD for private sale, and transfer price to seed-partners is planned to be 0.015 USD.
In addition, creating and maintaining liquidity is indispensable for the operation of a crypto asset projects. Developers must ensure that tokens are traded at high prices, such as by making the project more attractive and installing incentives regularly.
<h3 id="mcetoc_1g9tjvhre2ku" style="text-align: justify;">Stage 2: Marketing and Community Building</h3>
To issue a cryptocurrency and officially start an NFT project, it is essential to create a White paper or Pitch deck equivalent to the business plan.
Additionally, detailed market research is indispensable for launching an NFT project. From the kind of NFT, content and price range, the demographic factors of target customers including age, gender, social standpoint, behavior history, etc., as well as the nationality and living areas will be researched.
Creating a website, landing page, and promotion video is also essential for the stage of raising awareness. Many targeted customers are less interested in the technical content of the Whitepaper. Rather than that, a more funny and valuable content, for example, &ldquo;How much you can earn in a game?&rdquo;, which can be reached by everyone, regardless of age or characteristic will attract much more attention. With that mindset, Widiland promotes and attracts customers through SNS including Twitter, Facebook, Instagram, YouTube, and Discord&hellip;
<img class="responsiveImage" src="https://api.relipa.global/storage/527/nft-development-widiland-case-study.png" alt="Widiland marketing and communicaton building" />
AirDrop and referrals can help you expand the attraction and UX of your NFT, and the free trials can help you discover potential demand.
Also, for example, if you form a partnership with an apparel maker or a sports maker and sell fashion items and sneakers worn by characters in the game as a NFT, it will be easier to raise funds and widely approach the clients of each company efficiently.
In NFT project, if the content itself becomes popular, the price of related tokens will surely rise, and if the number of token holders increases, the number of fans and users of the project will naturally increase, creating a virtuous cycle. By conducting marketing through detailed search, and continuing to build a diverse community, we can do an NFT development project that can not be ignored.
<h3 id="mcetoc_1g9tjvhre2kv" style="text-align: justify;">Stage 3: Fundraising</h3>
The next stage is fundraising, when funds to actually operate the NFT project will be gathered based on the Tokenomics design and Pitch deck (Business plan).
Taking Widiland as an example, we first collect money from selling tokens to strategic partners, then raise more funds from partners through private sales, and after that conduct IDO at DEX. Each of them was executed within 2 to 3 months, and we succeeded in raising about 190 million JPY in total, and we did reach the target value.
Creating a Pitch deck is somehow not necessary, but it requires careful preparation and behind actions so that you can raise money as your plans or even more.

<h3 id="mcetoc_1g9tjvhre2l0" style="text-align: justify;">Stage 4: Token Listing (DEX / CEX)</h3>
To trade tokens, it is necessary to list them on a particular crypto assets exchange. In the case of NFT, the main exchange is DEX (Decentralized Exchange) like "Widiland" because it must be a coin that can be used on Blockchain based on Ethereum or same types of smart contracts.
Game players and investors will buy tokens by connecting their wallet directly to DEX. In "Widiland", you can use the WIDI to participate in games or purchase.
DEX is fully automated with smart contracts, so there are almost no fees. However, some tokens may be listed on CEX (Centralized Exchange), in that case, a fee will be required.
<h3 id="mcetoc_1g9tjvhre2l1" style="text-align: justify;">Stage 5: NFT Initial market&nbsp;</h3>
Since 2021, a multitude of NFT have been developed and traded in the market. Apart from selling in the specific marketplace for NFT only, if you want to set up and run your own project, it is common to raise funds by IDO (Initial DEX Offering). For example, in the case of NFT games, selling NFT such as characters, items, and accessories after offering the NFT initially in DEX (IDO) is very popular.
However, the situation did change in 2022, and there are increasing cases of selling NFTs before IDO in the form of "IGO (Initial Game Offering)" and "INO (Initial NFT Offering)".
Both IGO and INO, in some aspects, are the beforehand fundraising methods. These can create NFTs in advance, raise more funds by exchanging certain quantity of these NFTs before officially releasing, and use them for operation. If you sell the NFT initially, the attention to the project will increase, and when it is released officially, you can expect that the NFT sale transactions will be carried out earlier and more actively.

<h3 id="mcetoc_1g9tjvhre2l2" style="text-align: justify;">Stage 6: Official project release</h3>
After the above processes, the NFT project is finally released.
In that case, a careful testing whether the main NFT product can be released properly and without delay or not is essential. Also, in order to gain widespread trust, we must not forget to have a long-term vision of management before running into immediate profits. For example, adding new features and benefits on a regular basis is a good example.
In fact, for Widiland, the Beta version of Chapter 1 was completed at the end of May 2022, and a marketplace and DeFi functions (stalking, farming, treasure hunting) were added right after.
<h2 id="mcetoc_1g9tjvhre2l3" style="text-align: justify;">Pros and Cons of Using outsource NFT Development</h2>
As mentioned above, NFT development requires various preparation, know-how, and specialized knowledge, so inexperienced companies and start-ups cannot easily develop with their own resources only. That is why outsourcing development is strongly recommended.
Asking an IT company with a deep knowledge of Blockchain or an outsource company with talented engineers for help will ensure your success.
However, a thorough awareness about this kind of development method is important as besides the easy-to-see advantages, there are also some disadvantages that should be put under consideration.&nbsp;
<img class="responsiveImage" src="https://api.relipa.global/storage/525/nft-development-pros-and-cons.png" alt="NFT Development - Pros and Cons" />
<h3 id="mcetoc_1g9tjvhre2l4" style="text-align: justify;">Pros</h3>
<h4 style="text-align: justify;">1. Well-optimized Development process&nbsp;</h4>
The development process, such as the development of crypto assets, the creation and publication of NFT content and White papers until launching, and the appeal to investors and users, has been partially standardized. Therefore, if you outsource to a specialist, you will be able to get an early project outlook, unlike developing on your own from scratch.
By the way, if you have no actual experience, even if you can develop Blockchain and NFT yourself, you can not do marketing and other consulting work such as exchanging, building community and interacting with investors. Therefore, outsourcing firms need to be carefully selected.
<h4 style="text-align: justify;">2. High speed and good price</h4>
If you can choose a outsourcing company who has a track record of Blockchain and NFT development, once the project started, it will proceed very quickly. Moreover, it also contributes to cost reduction because there is only a little possibility that you will fail or have to start over. Especially in the case of outsourcing, it can be said that the advantage of low cost is quite high because the labor cost is cheaper than that in Japan while high quality development is still possible.&nbsp;
<ul>
<li style="text-align: justify;">Blockchain development team with specialized knowledge and experience</li>
</ul>
NFT Development requires deep knowledge and highly specialized development technology about Blockchain. Therefore, if you outsource to a company that has a highly experienced Blockchain development team, you will not only be able to respond to various requests, but you will also be able to be supported in troubleshooting after releasing, so the process itself is quite safe.
Especially, Vietnam is one of the world's leading blockchain development outsourcing countries. Compared to other countries and regions, we has built a long connection with Blockchain, and we have a great deal of experienced and well-skilled human resources, such as developing the world's most popular NFT game called "Axie Infinity".
<ul>
<li style="text-align: justify;">Practice time optimization</li>
</ul>
Using an outsourcing service, you can significantly reduce the development time, which will help you free up your time for other tasks.
<h3 id="mcetoc_1g9tjvhre2l5" style="text-align: justify;">Cons</h3>
<h4 style="text-align: justify;">1. Work management is not simple</h4>
Using outsourcing services, you can not manage everything in the development process or on-site situation. Reporting and communication are limited in quantity and time, which can lead to misunderstandings and extra costs due to unnecessary corrections.
<h4 style="text-align: justify;">2. Language barriers&nbsp;</h4>
Especially in outsource development, it may be difficult to communicate smoothly due to language barriers, cultures, and working mindset. Therefore, it will be necessary to confirm in advance whether there is a Bridge SE or engineer who is familiar with Japanese or not, so that there will be no discrepancy during development.
<h2 id="mcetoc_1g9tjvhre2l6" style="text-align: justify;">In conclusion</h2>
In the blog, we have provided an ultimate A to Z guideline of NFT Development process.&nbsp;

NFT Development - The ultimate guide from NFT Game Widiland

NFTs are attracting attention from many investors around the world as a proof of the irreplaceable and unique value of digital content. As proof of this, a digital art work published as a NFT in March 2021 was sold for about 7.9 billion JPY.
Nowadays, even artworks drawn by children are sold and bought at a very high price of several million JPY, and even game characters are also exhibited as NFT, which is definitely a investment target. So <a href="../../blogs/nft-development-the-ultimate-guide-from-nft-game-widiland" target="_blank" rel="noopener">how can we develop an NFT (Non-Fungible Token)?</a>
NFTs can list digital content such as images, videos, and event tickets in a dedicated marketplace with a simple procedure. However, when it comes to apps such as games, it is necessary to develop through a well-formed process. Therefore, in this blog, we will explain in detail what kind of programming language and framework is required to develop NFT.

<h2 id="mcetoc_1ga8h7o2p9g">About NFT</h2>
NFT stands for and has the meaning of "Non-Fungible Token". Bitcoin and other cryptocurrencies, even cash usually do not vary in value no matter how many token is exchanged. There is no difference in the value of 100 JPY for a person and 100 JPY for another. This "exchangeable&rdquo; means &ldquo;fungible".
On the other hand, NFT is an irreplaceable (non-fungible) token that proves ownership to digital content by a digital data unit on the blockchain, such as sculptures and jewels, giving those the value that is unique in the world. Traditionally, digital content can be duplicated indefinitely on the Internet, and the same images on one person's computer can exist on another person's computer as many times as possible. And it was almost impossible to prove any one of them as the owner. However, it was NFT that realized this in a way that it could not be tampered with or forged with blockchain technology, and it had a great impact on people&rsquo;s concern all over the world.
Therefore, by using NFT, it is possible to add value as an original ownership to images, videos, and music, such as paintings and hanging scrolls. Moreover, the target is expanding to RPG games and trading card games. One example is the NFT game "My Crypto Heroes", which was released for the first time in Japan. This game can be played on both PCs and smartphones, and players aim to conquer the world by collecting items such as weapons that are also NFTs while collecting world heroes made with NFTs. Characters and items are NFTs, so you can buy and sell them in a marketplace.
However, in NFT market, if you want to sell a character from a general online game or social game, you cannot do it. Unless it is a game created using a special technology called smart contract on the crypto asset of Ethereum, which will be explained later, it is impossible to add value to characters as an NFT or buy or sell it in the market.&nbsp;
In addition, it is possible to build a mechanism that rewards the original author each time the work is delivered to a buyer different from the secondary and tertiary by utilizing smart contracts. It can be said that it is a remarkable feature unique to NFT.
<h2 id="mcetoc_1ga8h7o2p9h">NFT and Ethereum</h2>
NFT trading and development cannot be considered without Ethereum. In other words, the NFT system works because of Ethereum, which is called a blockchain "platform&rdquo;, which is different from other cryptocurrencies. So, let's continue with the ERC standards that are essential for Ethereum and NFT development.
<h3 id="mcetoc_1ga8h7o2p9i">What is Ethereum?</h3>
Ethereum is the second most popular blockchain after Bitcoin. It was released in January 2014. The key currency is Ethereum (ETH), which generates blocks every 15 seconds, so it is much faster than Bitcoin, which takes about 10 minutes, and it can be traded in large quantities. Ethereum is a decentralized application platform, and by using a mechanism called smart contract, which will be described later, it is possible to create and run unique tokens and applications on the blockchain. This is a big difference from other crypto assets, and it is the reason why NFT can be operated.
Ethereum, which is a platform type, is a very attractive blockchain for developers because it has a high degree of freedom and various software can be created. Therefore, since its birth, many people have started to create their own tokens by utilizing this. However, if you make a token on the blockchain, you need an individual wallet (an online wallet that is absolutely necessary when dealing with virtual currency), and it is not compatible if the token standard is different. Therefore, if each developer freely creates tokens in his own way, it is not practical because it requires troublesome work such as setting up a different wallet each time.&nbsp;
Therefore, if this standard is unified, wallets can be centrally managed and compatibility will be created, so the idea that it will lead to the development of the Ethereum market due to its ease of use is born.
<h3 id="mcetoc_1ga8h7o2p9j">What is the ERC standard?</h3>
With the above circumstances, the common standard for smart contracts (described later) called "ERC" was established with the aim of improving convenience for the entire developer community. It will become a formal standard once it is proposed on GitHub and approved by the developer community. (GitHub is a service provided by Microsoft-affiliated US company GitHub that allows multiple software developers to manage and share source code.)
ERC20 was first born in November 2015, and when it was released, it was used to create a number of unique tokens. And ERC223 was born in March 2017 as the improved version.&nbsp;
Furthermore, "ERC721" was born in September of the same year with the purpose of developing the idea of ​​this common standard in a completely different direction.
Unlike the previous ERCs, this ERC721 has made it possible to create an irreplaceable new type of token called NFT. All NFTs are created according to the rules of this ERC721, and conversely, the app cannot be launched on Ethereum unless it complies with this standard. Of course, Japan's first NFT game "My Crypto Heroes" introduced earlier was also developed according to the ERC721 standard.
By the way, Canada's Dapper Labs launched the world's first NFT game "CryptoKitties" just two months after approval (November 2017) after proposing this ERC721. This "CryptoKitties" ignited the NFT game and at the same time raised the awareness of NFT worldwide.
<h2 id="mcetoc_1ga8h7o2p9k">Ethereum and smart contracts</h2>
ERC is a common standard for "smart contracts," which are indispensable technologies for Ethereum. A smart contract is a program that automatically executes transactions on the blockchain according to rules coded in a specific programming language. The program coded here is converted into a form that can be processed on the blockchain and then deployed. Software and applications once deployed on the blockchain are almost impossible to rewrite or tamper with. Moreover, it has the advantages of speed improvement and cost reduction.
ERC is proposed on GitHub by any developers and will become a formal smart contract standard if approved within the community, but the numbers following ERC represent the order in which they were proposed. This means that the first born ERC20 was proposed the 20th. And the 721st proposal and approval was ERC721.
Using the ERC721 standard, NFTs can be developed, certifying ownership of digital content and recording all transaction history on the Ethereum blockchain. Therefore, all transactions are traceable, so no matter how many times you buy or sell, you won't lose track of who your content belongs to. Moreover, if you embed a royalty clause in a smart contract, the original author will be paid a certain percentage each time a sale is completed, so the copyright is also firmly guaranteed.
<h2 id="mcetoc_1ga8h7o2p9l">"Solidity" language for creating Smart contracts</h2>
To develop an NFT according to the ERC721 standard, we use a program development language called "Solidity". Solidity is a high-level object-oriented programming language created solely for the development of smart contracts on Ethereum. Since it is a high-level language, it needs to be compiled like C language and Java. It is based on C ++ and is made with reference to Python and JavaScript, and especially because it has a grammar similar to JavaScript, it will be very easy to use if you have development experience with JavaScript. Moreover, as the update is ongoing, the accuracy will improve over time.
Since "Solidity" is a high-level programming language, it is easy for people to understand, but it is difficult for computers to understand. Therefore, we will go through the process of translating it into low-level bytecode using EVM (Ethereum virtual machine) and executing it. You can also create smart contracts in a Python-like language called "Vyper", but it is still inexperienced and practically not comparable to "Solidity". Therefore, it is safe to assume that "Solidity" will be used for NFT development for now.
<h2 id="mcetoc_1ga8h7o2p9m">"Truffle" framework of "Solidity"</h2>
Solidity has "Truffle" as a de facto standard framework, which is already widely used in many development situations. Truffle has the ability to automate the compilation, testing and deployment of smart contracts. The flow of using Truffle is to first create an application template. Next, compile the smart contract, launch the node for local development, deploy the smart contract to the node, and test it. Therefore, if you make good use of Truffle, you can quickly and easily create smart contracts using Solidity, so we highly recommend it.
<h2 id="mcetoc_1ga8h7o2p9n">Summary</h2>
I told you in detail about NFT (Non-Fungible Token). If you want to develop and implement NFT, the existence of Ethereum is indispensable. However, Ethereum is worried that gas charges (commissions) are soaring even in many virtual currencies. In other words, this high gas cost can be a major obstacle to entering the market.
Therefore, the development of a new blockchain that does not cost much fees is progressing, so there is a possibility that the way NFTs should be will change in the future. If more gameplay and investors can participate in the NFT market, the market size is expected to grow further in the future. In that sense, now is a great opportunity to develop NFTs.
Relipa is specialized only for Japanese companies, and excellent engineers will help you develop NFT (Non-Fungible Token). If you are a startup or developer who is thinking of entering the NFT market in earnest, please feel free to contact us.
