Signing

Learn how to sign messages on TRON.

Sign Message V1 (Hex)

Sign hex-encoded messages:


const message = tronWeb.toHex('Hello TRON!')
const signature = await provider.signMessage(message)
 
console.log('Signature:', signature)

Sign Message V2 (UTF-8)

Sign UTF-8 messages directly:


const message = 'Hello TRON!'
const signature = await provider.signMessageV2(message)
 
console.log('Signature:', signature)

Verify Signature


const message = 'Hello TRON!'
const signature = await provider.signMessageV2(message)
 
// Verify using TronWeb
const address = await tronWeb.trx.verifyMessageV2(message, signature)
console.log('Signer:', address)

Error Handling


try {
  const result = await provider.request({
    method: 'tron_requestAccounts'
  })
 
  if (result.code !== 200) {
    throw new Error(result.message)
  }
} catch (error) {
  if (error.code === 4001) {
    console.log('User rejected the request')
  } else {
    console.error('Error:', error.message)
  }
}
