Request Signature

The request method facilitates the use of templated transaction screens for signing transactions. The method will return SignResponse. It can be used to sign transactions for any EVM chain and screens can be whitelabeled to your branding.

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

Parameters

Parameter	Description
chainConfig	Defines the chain to be used for signature.
method	JSON RPC method name in String. Currently, the request method only supports the singing methods.
requestParams	Parameters for the corresponding method. The parameters should be in the list and correct sequence. Take a look at RPC methods to know more.
