示例

// All properties on a domain are optional
const domain = {
  name: 'TRON Mail',
  version: '1',
  chainId: '0x2b6653dc',
  verifyingContract: 'TUe6BwpA7sVTDKaJQoia7FWZpC9sK8WM2t'
};

// The named list of all type definitions
const types = {
  Person: [
    { name: 'name', type: 'string' },
    { name: 'wallet', type: 'address' }
  ],
  Mail: [
    { name: 'from', type: 'Person' },
    { name: 'to', type: 'Person' },
    { name: 'contents', type: 'string' }
  ]
};

// The data to sign
const value = {
  from: {

  },
  to: {

const result = await tronWeb.trx.verifyTypedData(domain, types, value, signature);
// verification result: true
