Computes the sign payload for an Authorization.Authorization in EIP-7702 format: keccak256('0x05' || rlp([chain_id, address, nonce])).

Imports

Named
import { Authorization } from 'ox'

Examples

The example below demonstrates computing the sign payload for an Authorization.Authorization. This payload can then be passed to signing functions like Secp256k1.sign.

import { Authorization, Secp256k1 } from 'ox'
 
const authorization = Authorization.from({
  address: '0x1234567890abcdef1234567890abcdef12345678',
  chainId: 1,
  nonce: 69n,
})
 
const payload = Authorization.getSignPayload(authorization)
 
const signature = Secp256k1.sign({
  payload,
  privateKey: '0x...',
})
