OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems.

We provide financial institutions with access to institutional FX and stablecoin liquidity and same-day settlements globally. Traders and developers can use the OpenFX API suite to automate the end-to-end trading and settlement process — deposit detection, quote streaming, trade execution, and settlement for multiple fiat currencies and stablecoins.

* Access to multiple currency pairs on a single platform at institutional exchange rates.
* Immediate trading without the need to pre-fund accounts on the platform.
* Same-day (T0) settlement into web3 wallets and bank accounts globally.
* Round-the-clock conversions with 24/7 liquidity and operational support.
