TransactionEnvelopeEip1559.from
Converts an arbitrary transaction object into an EIP-1559 Transaction Envelope.
Imports
Named
import { TransactionEnvelopeEip1559 } from 'ox'
Examples
import { TransactionEnvelopeEip1559, Value } from 'ox'
const envelope = TransactionEnvelopeEip1559.from({
chainId: 1,
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 { Secp256k1, TransactionEnvelopeEip1559, Value } from 'ox'
const envelope = TransactionEnvelopeEip1559.from({
chainId: 1,
maxFeePerGas: Value.fromGwei('10'),
maxPriorityFeePerGas: Value.fromGwei('1'),
to: '0x0000000000000000000000000000000000000000',
value: Value.fromEther('1'),
})
const signature = Secp256k1.sign({
payload: TransactionEnvelopeEip1559.getSignPayload(envelope),
privateKey: '0x...',
})
const envelope_signed = TransactionEnvelopeEip1559.from(envelope, {
signature,
})
{ chainId: 1, maxFeePerGas: 10000000000n, maxPriorityFeePerGas: 1000000000n, to: '0x0000000000000000000000000000000000000000', type: 'eip1559', value: 1000000000000000000n, r: 125...n, s: 642...n, yParity: 0, }
From Serialized
It is possible to instantiate an EIP-1559 Transaction Envelope from a TransactionEnvelopeEip1559.Serialized
value.
import { TransactionEnvelopeEip1559 } from 'ox'
const envelope = TransactionEnvelopeEip1559.from('0x02f858018203118502540be4008504a817c800809470997970c51812dc3a010c7d01b50e0d17dc79c8880de0b6b3a764000080c08477359400e1a001627c687261b0e7f8638af1112efa8a77e23656f6e7945275b19e9deed80261')
{ chainId: 1, maxFeePerGas: 10000000000n, maxPriorityFeePerGas: 1000000000n, to: '0x0000000000000000000000000000000000000000', type: 'eip1559', value: 1000000000000000000n, }
