Networks & Tokens

Onboard Exchange operates in a non-custodial manner, powered by smart contracts. This approach prioritizes security and user control over their funds.

While the underlying protocol is compatible across all EVM chains, Onboard Exchange itself currently supports selected networks, to ensure robust liquidity and a smooth user experience. However, we’re constantly evaluating and adding new networks to Exchange, so stay tuned for updates as we expand our network coverage!

Below is a list of supported networks & tokens on mainnet, as well as testnet, allowing you to test your integration before deployment.
