@ethereumjs/tx / LegacyTx

Class: LegacyTx

Defined in: legacy/tx.ts:82

An Ethereum non-typed (legacy) transaction

Implements

Constructors

Constructor

new LegacyTx(txData, opts): LegacyTx

Defined in: legacy/tx.ts:123

This constructor takes the values, validates them, assigns them and freezes the object.

It is not recommended to use this constructor directly. Instead use the static factory methods to assist in creating a Transaction object from varying data types.

Parameters

txData

LegacyTxData

opts

TxOptions = {}

Returns

LegacyTx

getEffectivePriorityFee()

getEffectivePriorityFee(baseFee?): bigint

getHashedMessageToSign()

getHashedMessageToSign(): Uint8Array<ArrayBufferLike>

Defined in: legacy/tx.ts:271

Returns the hashed serialized unsigned tx, which can be used to sign the transaction (e.g. for sending to a hardware wallet).

Returns

Uint8Array<ArrayBufferLike>

Implementation of

TransactionInterface.getHashedMessageToSign


getIntrinsicGas()

getIntrinsicGas(): bigint

Defined in: legacy/tx.ts:297

The minimum gas limit which the tx to have to be valid. This covers costs as the standard fee (21000 gas), the data fee (paid for each calldata byte), the optional creation fee (if the transaction creates a contract), and if relevant the gas to be paid for access lists (EIP-2930) and authority lists (EIP-7702).

Returns

bigint

Implementation of

TransactionInterface.getIntrinsicGas


getMessageToSign()

getMessageToSign(): Uint8Array<ArrayBufferLike>[]

Defined in: legacy/tx.ts:248

Returns the raw unsigned tx, which can be used to sign the transaction (e.g. for sending to a hardware wallet).

Note: the raw message message format for the legacy tx is not RLP encoded and you might need to do yourself with:

import { RLP } from '@ethereumjs/rlp'
const message = tx.getMessageToSign()
const serializedMessage = RLP.encode(message)) // use this for the HW wallet input

Returns

Uint8Array<ArrayBufferLike>[]

Implementation of

TransactionInterface.getMessageToSign


getMessageToVerifySignature()

getMessageToVerifySignature(): Uint8Array<ArrayBufferLike>

Defined in: legacy/tx.ts:320

Computes a sha3-256 hash which can be used to verify the signature

Returns

Uint8Array<ArrayBufferLike>

Implementation of

TransactionInterface.getMessageToVerifySignature


getSenderAddress()

getSenderAddress(): Address

Defined in: legacy/tx.ts:396

Returns

Address

Implementation of

TransactionInterface.getSenderAddress


getSenderPublicKey()

getSenderPublicKey(): Uint8Array

Defined in: legacy/tx.ts:331

Returns the public key of the sender

Returns

Uint8Array

Implementation of

TransactionInterface.getSenderPublicKey


getUpfrontCost()

getUpfrontCost(): bigint

Defined in: legacy/tx.ts:303

The up front amount that an account must have for this transaction to be valid

Returns

bigint

Implementation of

TransactionInterface.getUpfrontCost


getValidationErrors()

getValidationErrors(): string[]

Defined in: legacy/tx.ts:384

Returns

string[]

Implementation of

TransactionInterface.getValidationErrors


hash()

hash(): Uint8Array

Defined in: legacy/tx.ts:313

Computes a sha3-256 hash of the serialized tx.

This method can only be used for signed txs (it throws otherwise). Use Transaction.getMessageToSign to get a tx hash for the purpose of signing.

Returns

Uint8Array

Implementation of

TransactionInterface.hash


isSigned()

isSigned(): boolean

Defined in: legacy/tx.ts:187

Returns

boolean

Implementation of

TransactionInterface.isSigned


isValid()

isValid(): boolean

Defined in: legacy/tx.ts:388

Returns

boolean

Implementation of

TransactionInterface.isValid


raw()

raw(): LegacyTxValuesArray

Defined in: legacy/tx.ts:208

Returns a Uint8Array Array of the raw Bytes of the legacy transaction, in order.

Format: [nonce, gasPrice, gasLimit, to, value, data, v, r, s]

For legacy txs this is also the correct format to add transactions to a block with createBlockFromBytesArray (use the serialize() method for typed txs).

For an unsigned tx this method returns the empty Bytes values for the signature parameters v, r and s. For an EIP-155 compliant representation have a look at Transaction.getMessageToSign.

Returns

LegacyTxValuesArray

Implementation of

TransactionInterface.raw


serialize()

serialize(): Uint8Array

Defined in: legacy/tx.ts:231

Returns the serialized encoding of the legacy transaction.

Format: rlp([nonce, gasPrice, gasLimit, to, value, data, v, r, s])

For an unsigned tx this method uses the empty Uint8Array values for the signature parameters v, r and s for encoding. For an EIP-155 compliant representation for external signing use Transaction.getMessageToSign.

Returns

Uint8Array

Implementation of

TransactionInterface.serialize


sign()

sign(privateKey, extraEntropy): LegacyTx

Defined in: legacy/tx.ts:400

Parameters

privateKey

Uint8Array

extraEntropy
boolean Uint8Array<ArrayBufferLike>

Returns

LegacyTx

Implementation of

TransactionInterface.sign


supports()

supports(capability): boolean

Defined in: legacy/tx.ts:183

Checks if a tx type defining capability is active on a tx, for example the EIP-1559 fee market mechanism or the EIP-2930 access list feature.

Note that this is different from the tx type itself, so EIP-2930 access lists can very well be active on an EIP-1559 tx for example.

This method can be useful for feature checks if the tx type is unknown (e.g. when instantiated with the tx factory).

See Capabilities in the types module for a reference on all supported capabilities.

Parameters

capability

number

Returns

boolean

Implementation of

TransactionInterface.supports


toCreationAddress()

toCreationAddress(): boolean

Defined in: legacy/tx.ts:287

If the tx’s to is to the creation address

Returns

boolean

Implementation of

TransactionInterface.toCreationAddress


toJSON()

toJSON(): JSONTx

Defined in: legacy/tx.ts:375

Returns an object with the JSON representation of the transaction.

Returns

JSONTx

Implementation of

TransactionInterface.toJSON


verifySignature()

verifySignature(): boolean

Defined in: legacy/tx.ts:392

Returns

boolean

Implementation of

TransactionInterface.verifySignature
