Supported chains by use case
When calling the Basic API, you can use the Network ID listed in the table below as the chain_id
parameter. Basic API only supports EVM-compatible blockchains for now.
We will continue to add support for new blockchains. If there is a chain that you wish to support, but we do not, please let us know by reaching out to [email protected].
