Request Signature

The request method facilitates the use of templated transaction screens for signing transactions. This function returns a promise of the signature that can be used to broadcast the transaction.

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

Method

request(chainConfig: ChainConfig, method: string, params: unknown[], path?: string): Promise<string>;

Parameters

Arguments	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.

Examples
