API Reference

Supported Chains & Testnets

Currently supported chains and testnets

SimpleHash aims to provide the broadest coverage across chains with active developer communities. The following table indicates the current chain support. If you have a chain or network you'd like to see supported, please reach out at [email protected].

When making calls using the API, use either the Query string or Cross-chain ID to specify the desired chain(s).

We also have an Available Chains endpoint that returns this information programmatically.

SimpleHash also supports querying lazy minted NFTs for the OpenSea shared contracts on Ethereum and Polygon.
