Fiat on/off ramps made simple.

As long-time contributors to the crypto ecosystem, we believe that mass adoption can only happen once there are more natural methods readily available for people to enter and exit the crypto market.

We designed our Crypto Exchange API with this goal in mind and that’s why we made it possible for anyone to buy and sell crypto without requiring a Bity account nor going through identity verification, up to CHF 1’000.- daily.

We did the hard work for you

Bridging the crypto and fiat worlds is one tricky business.

We’ve spent years building in-depth regulatory know-how, strong banking relationships, and the infrastructure needed to open this bridge to everyone who is trying to make cryptocurrencies easier to use in everyday life.

With this API, and little development effort on your side, it is now possible for you to offer seamless fiat on/off ramps and crypto swaps to the users of your platform.

Build your own solution

Our Crypto Exchange API is open and available for anyone to use or integrate.

We offer all the necessary endpoints to securely buy, sell, and swap cryptocurrencies at market price, operated by our engine.

In addition, you can also create sophisticated workflows and interfaces to solve specific problems like salary payments from crypto to fiat or receiving fiat from customers paying in crypto.

Monetize your platform

Monetizing projects in the crypto space is not always easy.

We understand this and we will be sharing our profits with you if your integration is eligible for partnership.

This collaboration model has been successfully implemented with MyEtherWallet since the beginning of 2017 and we are now extending it to anyone who wants to integrate our Crypto Exchange API in their platform or app.

Curious about how we make it work?

The Crypto Exchange API gives complete access to the capabilities of our engine for non-custodial crypto exchanges. Non-custodial means that we don’t hold customer’s funds and that we execute the exchange as soon as the payment arrives to us. For a user, the interaction with us is as simple as:

  1. opening an exchange order
  2. sending the payment, and
  3. receiving the funds in the desired currency.

Anyone on the Internet can open exchange orders in our engine via the Crypto Exchange API. Exchanges can be made without having to open an account with us nor go through a Know Your Customer (KYC) verification process. This is possible on up to CHF 1’000.- per day / CHF 100’000.- year, per crypto address and IBAN. All that needs to be provided is a standard cryptographic proof for us to make sure we will be sending the funds back to the user. Integrators can partner with us to directly monetize their platform with our Crypto Exchange API. To begin, they will need to complete an onboarding process where we’ll establish a legal agreement between both parties and guarantee the quality of the integration. Once fully onboard, we will share between 10% and 30% of the profits produced by successful exchanges performed by the integrator’s users.
