LegacyTransaction

caver.transaction.legacyTransaction.create(transactionObject)

LegacyTransaction represents a . A can execute a LegacyTransaction only with . The transactionObject can have properties below to create a LegacyTransaction.

LegacyTransaction has the properties below as its member variables. Properties marked as optional refer to properties that can be optionally given in transactionObject when the user creates LegacyTransaction.

NOTE: You can create an instance of LegacyTransaction from RLP-encoded strings. Please refer to the below example. NOTE: caver.transaction.legacyTransaction.create is supported since caver-js .

NOTE: As of caver-js , creating transactions is only supported using the create function. If you've been creating transactions using a constructor like new caver.transaction.legacyTransaction({...}), please change it to caver.transaction.legacyTransaction.create({...}).

properties

Name
Type
Description

gas

string

The maximum amount of transaction fee the transaction is allowed to use.

value

string

(optional, default: '0x0') The amount of KLAY in peb to be transferred. You can use caver.utils.toPeb.

from

string

(optional) The address of the sender. If omitted, the keyring address used for signing will be set.

to

string

(optional, default: '0x') The account address that will receive the transferred value or smart contact address if a legacy transaction execute smart contract. If a legacy transaction deploys a smart contract, to does not need to be defined.

input

string

(optional) Data attached to the transaction, used for smart contract deployment/execution.

signatures

Array

(optional) An array of signatures. A legacy transaction can have only one signature.

nonce

string

(optional) A value used to uniquely identify a sender’s transaction. If omitted, caver.rpc.klay.getTransactionCount(address, 'pending') will be used to set nonce.

gasPrice

string

(optional) A multiplier to get how much the sender will pay in tokens. If omitted, caver.rpc.klay.getGasPrice will be used to set gasPrice.

chainId

string

(optional) The chain id of the Klaytn network. If omitted, caver.rpc.klay.getChainId will be used to set chainId.

EthereumDynamicFee

caver.transaction.ethereumDynamicFee.create(transactionObject)

EthereumDynamicFee has the properties below as its member variables. Properties marked as optional refer to properties that can be optionally given in transactionObject when the user creates EthereumDynamicFee. And note that EthereumDynamicFee does not use gasPrice, it uses maxPriorityFeePerGas and maxFeePerGas.

properties

Name
Type
Description

gas

string

The maximum amount of transaction fee the transaction is allowed to use.

value

string

(optional, default: '0x0') The amount of KLAY in peb to be transferred. You can use caver.utils.toPeb.

from

string

(optional) The address of the sender. If omitted, it will be set to the keyring address used for signing.

to

string

(optional, default: '0x') The account address that will receive the transferred value or smart contact address when an ethereum dynamic fee transaction executes a smart contract. When an ethereum dynamic fee transaction deploys a smart contract, to does not need to be defined.

input

string

(optional) Data attached to the transaction, used for smart contract deployment/execution.

signatures

Array

(optional) An array of signatures. An ethereum dynamic fee transaction can have only one signature.

nonce

string

(optional) A value used to uniquely identify a sender’s transaction. If omitted, it will be set to caver.rpc.klay.getTransactionCount(address, 'pending').

maxPriorityFeePerGas

string

(optional) Gas tip cap for the transaction in peb. Since Klaytn has a fixed gas price, it should be set to the same value as caver.rpc.klay.getGasPrice. If omitted, it will be set to caver.rpc.klay.getMaxPriorityFeePerGas().

maxFeePerGas

string

(optional) A maximum amount to pay for the transaction to execute. Since Klaytn has a fixed gas price, it should be set to the same value as caver.rpc.klay.getGasPrice. If omitted, the value of baseFeePerGas * 2 + maxPriorityFeePerGas is set to maxFeePerGas.

chainId

string

(optional) The chain id of the Klaytn network. If omitted, it will be set to caver.rpc.klay.getChainId.

accessList

Array

(optional) As an EIP-2930 access list that contains all storage slots and addresses read and written by the transaction.
