It is primarily used in the context of WalletConnect, a protocol for connecting decentralized applications (dApps) to mobile wallets with QR code scanning or deep linking.

What are @walletconnect/jsonrpc-types's main functionalities?

Type Definitions for JSON-RPC Methods

This feature provides type definitions for JSON-RPC requests, ensuring that the request object adheres to the expected structure.

import { IJsonRpcRequest } from '@walletconnect/jsonrpc-types';

const request: IJsonRpcRequest = {
  id: 1,
  jsonrpc: '2.0',
  method: 'eth_sendTransaction',
  params: [{
    from: '0x1234567890abcdef1234567890abcdef12345678',
    to: '0xabcdefabcdefabcdefabcdefabcdefabcdefabcdef',
    value: '0x1',
    gas: '0x5208',
    gasPrice: '0x3b9aca00',
    nonce: '0x0',
    data: '0x'
  }]
};

Type Definitions for JSON-RPC Responses

This feature provides type definitions for JSON-RPC responses, including both success and error responses, ensuring that the response objects adhere to the expected structure.

import { IJsonRpcResponseSuccess, IJsonRpcResponseError } from '@walletconnect/jsonrpc-types';

const successResponse: IJsonRpcResponseSuccess = {
  id: 1,
  jsonrpc: '2.0',
  result: '0x1'
};

const errorResponse: IJsonRpcResponseError = {
  id: 1,
  jsonrpc: '2.0',
  error: {
    code: -32600,
    message: 'Invalid Request'
  }
};

Type Definitions for JSON-RPC Errors

This feature provides type definitions for JSON-RPC errors, ensuring that error objects adhere to the expected structure.

import { IJsonRpcError } from '@walletconnect/jsonrpc-types';

const error: IJsonRpcError = {
  code: -32601,
  message: 'Method not found'
};
