TxEnvelopeTempo.encodeForSigning

Encodes a TxEnvelopeTempo.TxEnvelopeTempo for sender signing.

Returns the raw serialized transaction bytes that are hashed by TxEnvelopeTempo.getSignPayload. Sender signatures are stripped, and fee payer signatures are normalized to the sender pre-sign marker.

Imports

Named
import { TxEnvelopeTempo } from 'ox/tempo'

Examples

import { Hash } from 'ox'
import { TxEnvelopeTempo } from 'ox/tempo'
 
const envelope = TxEnvelopeTempo.from({
  chainId: 1,
  calls: [{
    to: 'tempox0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  }],
  nonce: 0n,
})
 
const encoded = TxEnvelopeTempo.encodeForSigning(envelope)
const payload = Hash.keccak256(encoded)

envelope.calls

  • Type: readonly Call[]

Array of calls to execute.

envelope.chainId

  • Type: numberType

EIP-155 Chain ID.

envelope.feePayerSignature

  • Type: { r: bigintType; s: bigintType; yParity: numberType; }
  • Optional

envelope.gas

  • Type: bigintType
  • Optional

Gas provided for transaction execution

envelope.keyAuthorization

  • Type: Signed

envelope.maxPriorityFeePerGas

  • Type: bigintType
  • Optional

Max priority fee per gas (in wei).

envelope.nonce

  • Type: bigintType
  • Optional

Unique number identifying this transaction

envelope.nonceKey

  • Type: bigintType
  • Optional

Nonce key for 2D nonce system (192 bits).

envelope.signature

  • Type: SignatureEnvelope
  • Optional

envelope.type

  • Type: type

Transaction type

envelope.validAfter

  • Type: numberType
  • Optional

Transaction can only be included in a block after this timestamp.

envelope.validBefore

  • Type: numberType
  • Optional

Transaction can only be included in a block before this timestamp.

Return Type

The serialized transaction bytes used as the sender signing preimage.
