About CCXT
One unified API for crypto exchanges and prediction markets — built in the open, by the community, since 2017.
How it started
CCXT — the CryptoCurrency eXchange Trading library — began in 2017, in the early days of algorithmic crypto trading. Every exchange spoke its own dialect: different endpoints, different signing schemes, different data formats. Anyone who wanted to trade on more than one venue had to write and maintain a separate integration for each. CCXT set out to solve that once, for everyone: a single, unified API that abstracts away the differences between exchanges, so the same code works everywhere. What started as one developer's tool quickly became the de-facto standard for connecting to crypto markets — and today it covers 100+ exchanges and prediction markets across JavaScript/TypeScript, Python, PHP, C#, Go and Java.
Open source, forever
CCXT is free and open-source software released under the MIT license— anyone can use it to build commercial or open-source software on top of it, freely. All development happens in public on GitHub: every exchange integration, every fix and every release is out in the open, reviewable by anyone. That transparency is a big part of why developers, funds and companies trust CCXT with code that moves real money.
Built by thousands
CCXT is one of the most popular open-source projects in the crypto space, powered by a community of thousands — contributors who add exchanges, fix bugs and improve the library, alongside the developers, data scientists and traders who battle-test it every day and report what they find. The project grows through this collaboration, and new contributors are always welcome: start with the contributing guide.
