Relipa is pleased to share a new customer interview featuring RENKIN, a crypto asset lending service designed for the Japanese market.
RENKIN enables users to lend their crypto assets and receive lending fees in return. Relipa supported the project from requirements gathering and system design through development, testing, feedback, and production release.
In this customer interview, the RENKIN team shares the story behind the service, their experience working with Relipa, and the operational improvements achieved through the project.

Building RENKIN Through Continuous Collaboration
The RENKIN project began with a clear idea: creating a trusted platform where users could put their idle crypto assets to work.
As the project progressed, both teams worked closely to turn that concept into a practical service. Relipa supported the development of the frontend and backend systems, wallet integration, and integrations with external services.
The development process also involved continuous discussions around specifications and implementation approaches. Rather than simply implementing requirements as provided, the Relipa team reviewed the proposed specifications and suggested improvements where appropriate.
This collaborative approach helped the project move forward while considering both technical requirements and future operations.
A Development Partner Selected for Web3 Experience
Because RENKIN handles crypto assets, the vendor selection process placed particular importance on development experience, Web3 expertise, understanding of crypto wallets, pricing, and communication.
After discussing the project with several development vendors, the RENKIN team selected Relipa based on its development experience, communication, and competitive pricing.
The interview also highlights how these factors contributed to the development partnership throughout the project.
Improving Operations with Automated Transfers
One of the key challenges before the introduction of automated transfers was the manual transfer process.
Manual transfers required multiple checks to reduce the risk of human error, including incorrect transfers. This process required significant time and could create delays in service delivery.
Relipa developed an automatic transfer feature that now processes transfers at a scheduled time.
According to the RENKIN team, the feature has reduced the operational burden associated with manual transfers and made daily operations more efficient. From the user perspective, automated transfers also provide a more seamless experience when lending crypto assets.
Customer Feedback on Relipa’s Development Approach
The RENKIN team also shared their impressions of working with Relipa.
One point they particularly appreciated was Relipa’s approach to reviewing requirements and considering potential issues beyond the initial specifications.
Instead of focusing only on whether a feature works according to the requirements, the team discussed how certain specifications might affect future operations and explored alternative approaches when necessary.
Several suggestions from Relipa were ultimately incorporated into the service and have continued to be useful in its ongoing operations.
