TransactionEnvelopeEip4844.from

Converts an arbitrary transaction object into an EIP-4844 Transaction Envelope.

Imports

Named

import { TransactionEnvelopeEip4844 } from 'ox'

Examples

import { Blobs, TransactionEnvelopeEip4844, Value } from 'ox'
import { kzg } from './kzg'
 
const blobs = Blobs.from('0xdeadbeef')
const blobVersionedHashes = Blobs.toVersionedHashes(blobs, { kzg })
 
const envelope = TransactionEnvelopeEip4844.from({
  chainId: 1,
  blobVersionedHashes,
  maxFeePerBlobGas: Value.fromGwei('3'),
  maxFeePerGas: Value.fromGwei('10'),
  maxPriorityFeePerGas: Value.fromGwei('1'),
  to: '0x0000000000000000000000000000000000000000',
  value: Value.fromEther('1'),
})

Attaching Signatures

It is possible to attach a signature to the transaction envelope.

import { Blobs, Secp256k1, TransactionEnvelopeEip4844, Value } from 'ox'
import { kzg } from './kzg'
 
const blobs = Blobs.from('0xdeadbeef')
const sidecars = Blobs.toSidecars(blobs, { kzg })
const blobVersionedHashes = Blobs.sidecarsToVersionedHashes(sidecars)
 
const envelope = TransactionEnvelopeEip4844.from({
  blobVersionedHashes,
  chainId: 1,
  maxFeePerBlobGas: Value.fromGwei('3'),
  maxFeePerGas: Value.fromGwei('10'),
  maxPriorityFeePerGas: Value.fromGwei('1'),
  to: '0x0000000000000000000000000000000000000000',
  value: Value.fromEther('1'),
})
 
const signature = Secp256k1.sign({
  payload: TransactionEnvelopeEip4844.getSignPayload(envelope),
  privateKey: '0x...',
})
 
const envelope_signed = TransactionEnvelopeEip4844.from(envelope, { 
  sidecars, 
  signature, 
})
{
   blobVersionedHashes: [...],
   chainId: 1,
   maxFeePerBlobGas: 3000000000n,
   maxFeePerGas: 10000000000n,
   maxPriorityFeePerGas: 1000000000n,
   to: '0x0000000000000000000000000000000000000000',
   type: 'eip4844',
   value: 1000000000000000000n,
   r: 125...n,
   s: 642...n,
   yParity: 0,
 }

From Serialized

It is possible to instantiate an EIP-4844 Transaction Envelope from a TransactionEnvelopeEip4844.Serialized value.

import { TransactionEnvelopeEip4844 } from 'ox'
 
const envelope = TransactionEnvelopeEip4844.from('0x03f858018203118502540be4008504a817c800809470997970c51812dc3a010c7d01b50e0d17dc79c8880de0b6b3a764000080c08477359400e1a001627c687261b0e7f8638af1112efa8a77e23656f6e7945275b19e9deed80261')
{
   blobVersionedHashes: [...],
   chainId: 1,
   maxFeePerGas: 10000000000n,
   to: '0x0000000000000000000000000000000000000000',
   type: 'eip4844',
   value: 1000000000000000000n,
 }
