Bridge is an API that moves money between fiat currencies (such as Nigerian naira, Ghanaian cedi and more) and stablecoins (such as USDC, USDT). You connect your app to Bridge once. After that, your customers can:
  • Buy stablecoins with fiat. Known as onramp.
  • Sell stablecoins for fiat paid to a bank account or mobile money wallet. Known as offramp.
You don’t need to hold stablecoins, talk to banks, or manage liquidity. Bridge handles that, and tells you what is happening at every step.

​
What you can build

Onramp

A customer pays in fiat and receives USDC in their wallet.

Offramp

A customer sends USDC and receives fiat in their bank or mobile money wallet.
