Our OTC (Over-the-Counter) exchange development project involved creating a platform that enables users to trade cryptocurrencies securely and efficiently. The client required a system with cold storage for enhanced security and a KYC (Know Your Customer) module to ensure compliance with regulatory requirements. We utilized a tech stack consisting of Node.js, React, TON SDK, Solana Web3.js, PostgreSQL, Redis, Docker, WebSocket, and GitLab CI/CD to develop the platform. The project was completed within a timeframe of six months, with a team of eight developers, two QA engineers, and one project manager.
The OTC exchange was designed to operate in the European market, with a primary focus on the German and French markets. The client's business requirements included the need for a high-performance matching engine, escrow services, and multisig wallets for secure transactions. Additionally, the platform had to be integrated with a liquidity provider to ensure sufficient liquidity for trades. We also implemented a RNG (Random Number Generator) for generating unique transaction IDs and a high-load balancing system to handle a large number of concurrent transactions.
To ensure the security of user funds, we implemented a cold storage system that stores private keys offline, reducing the risk of hacking and theft. The KYC module was integrated to verify user identities and prevent money laundering and other illicit activities. We also implemented a slippage control system to prevent large price fluctuations during transactions. The order book was designed to provide real-time updates, and the backend was built to handle a high volume of requests without compromising performance.
Client Requirements
The client's primary objective was to create an OTC exchange that could facilitate secure and efficient transactions while ensuring compliance with regulatory requirements. The client also required a system that could handle a high volume of trades without compromising performance. Furthermore, the client needed a platform that could integrate with existing systems, such as liquidity providers and payment gateways. The client's business model relied on generating revenue through transaction fees, and therefore, the platform had to be designed to handle a large number of transactions while minimizing latency.
The client's requirements also included the need for a user-friendly interface, both for the web and mobile applications. The platform had to be designed to provide real-time updates, and the client required a system that could handle multiple cryptocurrencies, including Bitcoin, Ethereum, and Solana. The client also needed a system that could integrate with existing KYC and AML (Anti-Money Laundering) systems to ensure compliance with regulatory requirements. We worked closely with the client to understand their requirements and developed a platform that met their needs.
The client's target audience was institutional investors and high-net-worth individuals who required a secure and efficient platform for trading cryptocurrencies. The client's marketing strategy involved partnering with liquidity providers and payment gateways to offer a comprehensive solution to their clients. The client also planned to offer a white-label solution to other businesses, allowing them to create their own branded OTC exchanges.
Technical Challenges
One of the technical challenges we faced was developing a high-performance matching engine that could handle a large number of concurrent transactions. We used a combination of Node.js and Redis to develop a scalable and high-performance matching engine. Another challenge was integrating the KYC module with the existing system, which required significant modifications to the backend. We used a third-party KYC service to verify user identities and ensure compliance with regulatory requirements.
We also faced challenges in implementing a cold storage system that could store private keys securely. We used a combination of hardware and software solutions to develop a secure cold storage system. The system was designed to store private keys offline, reducing the risk of hacking and theft. We also implemented a multisig wallet system to ensure that transactions were secure and could only be authorized by multiple parties.
To ensure the security of the platform, we implemented a range of security measures, including encryption, firewalls, and access controls. We also conducted regular security audits and penetration testing to identify vulnerabilities and ensure that the platform was secure. We used a combination of open-source and proprietary tools to develop the platform, and we worked closely with the client to ensure that the platform met their requirements.
- Matching engine: Node.js and Redis
- KYC module: Third-party KYC service
- Cold storage: Hardware and software solutions
- Multisig wallet: Proprietary solution
- Security measures: Encryption, firewalls, and access controls
Solution Architecture
The architecture of the OTC exchange consisted of a frontend, backend, and database. The frontend was developed using React and provided a user-friendly interface for users to trade cryptocurrencies. The backend was developed using Node.js and handled all the business logic, including the matching engine, KYC module, and cold storage system. The database was developed using PostgreSQL and stored all the transaction data and user information.
The platform was designed to be scalable and could handle a large number of concurrent transactions. We used a combination of load balancers and high-performance servers to ensure that the platform could handle a high volume of requests. The platform was also designed to be secure, and we implemented a range of security measures, including encryption, firewalls, and access controls.
The matching engine was designed to provide real-time updates, and the order book was updated in real-time. The platform was also integrated with a liquidity provider to ensure sufficient liquidity for trades. We used a combination of open-source and proprietary tools to develop the platform, and we worked closely with the client to ensure that the platform met their requirements.
Results Delivered
The client received a fully functional OTC exchange that met their requirements. The platform was designed to be secure, efficient, and scalable, and it provided a user-friendly interface for users to trade cryptocurrencies. The client was able to generate revenue through transaction fees, and the platform was designed to handle a large number of transactions without compromising performance.
The client was also able to integrate the platform with existing systems, such as liquidity providers and payment gateways. The client's marketing strategy involved partnering with liquidity providers and payment gateways to offer a comprehensive solution to their clients. The client also planned to offer a white-label solution to other businesses, allowing them to create their own branded OTC exchanges.
The project was completed within a timeframe of six months, and the client was satisfied with the final product. We worked closely with the client to ensure that the platform met their requirements, and we provided ongoing support and maintenance to ensure that the platform continued to operate smoothly.

Frequently Asked Questions
What is an OTC exchange?
An OTC exchange is a platform that enables users to trade cryptocurrencies securely and efficiently. It is designed to provide a secure and efficient way for users to trade cryptocurrencies, and it is typically used by institutional investors and high-net-worth individuals.
How does a matching engine work?
A matching engine is a system that matches buy and sell orders on an exchange. It is designed to provide real-time updates, and it is typically used on high-frequency trading platforms. The matching engine uses a range of algorithms to match orders, including price, time, and quantity.
What is cold storage?
Cold storage is a system that stores private keys offline, reducing the risk of hacking and theft. It is typically used on cryptocurrency exchanges to store private keys securely. The cold storage system is designed to provide an additional layer of security, and it is typically used in combination with other security measures, such as encryption and firewalls.
