Request signature

The request method facilitates the use of prebuilt transaction screens for signing transactions. The method returns SignResponse. It can be used to sign transactions for any EVM chain and screens can be customized to match your branding.

Configure chains during initialization with Web3AuthOptions(chains: [...]). The request method uses those chains; you no longer pass a separate chain configuration argument.

Please check the list of JSON RPC methods, noting that the request method currently supports only the signing methods.
