ExchangeX OTC – P2P & OTC Crypto Exchange Platform Development

Comfygen partnered with a fintech startup to build ExchangeX OTC, a hybrid crypto exchange platform supporting P2P and Over-the-Counter (OTC) trading functionalities.

The goal was to create a decentralized yet secure environment where users can trade directly, bypassing traditional intermediaries. This custom-built platform empowers users with privacy, transparency, and control over crypto transactions, with fiat payment integrations across regions like the UAE, India, and Nigeria.
