TransactionEnvelopeEip7702.getSignPayload
Returns the payload to sign for a TransactionEnvelopeEip7702.TransactionEnvelopeEip7702.
Imports
import { TransactionEnvelopeEip7702 } from 'ox'Examples
The example below demonstrates how to compute the sign payload which can be used with ECDSA signing utilities like Secp256k1.sign.
import { Secp256k1, TransactionEnvelopeEip7702 } from 'ox'
 
const envelope = TransactionEnvelopeEip7702.from({
  authorizationList: [...],
  chainId: 1,
  nonce: 0n,
  maxFeePerGas: 1000000000n,
  gas: 21000n,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1000000000000000000n,
})
 
const payload = TransactionEnvelopeEip7702.getSignPayload(envelope)
'0x...' const signature = Secp256k1.sign({ payload, privateKey: '0x...' })Definition
