Working with Klaytn Transaction Types

PreviousTransactionNextConfiguration

Last updated 2 years ago

Klaytn has various types of transaction and each type of transaction consists of different fields. Therefore, users should understand the transaction types and specify the correct one when sending and signing a transaction. Related APIs: klay_signTransaction, klay_sendTransaction, klay_signTransactionAsFeePayer, klay_sendTransactionAsFeePayer, personal_signTransaction, personal_sendTransaction.

TxTypeLegacyTransaction

TxTypeLegacyTransaction represents a type of transaction existed previously in Klaytn. This transaction type exists to support compatibility. For more information, see .

Parameters

Name
Type
Description

from

20-byte DATA

The address from which the transaction is sent.

to

20-byte DATA

(optional when creating a new contract) The address to which the transaction is directed.

gas

QUANTITY

(optional, default: 90000) Integer of the gas provided for the transaction execution. Unused gas will be refunded to the sender. If the specified gas is not enough to execute the transaction, the transaction is reverted.

gasPrice

QUANTITY

(optional, default: 25000000000 Peb) Integer of the gasPrice. The transaction fee is calculated by the multiplication of gas and gasPrice.

value

QUANTITY

(optional) Integer of the value sent with this transaction.

data

DATA

The compiled byte code of a contract to deploy or data (function indicator and parameter values) required to call a contract.

nonce

QUANTITY

(optional) Integer of a nonce.

Example

// Request

TxTypeFeeDelegatedSmartContractDeployWithRatio

Parameters

Name
Type
Description

typeInt

Integer

The integer indicating TxTypeFeeDelegatedSmartContractDeployWithRatio: 42

from

20-byte DATA

The address from which the transaction is sent.

to

20-byte DATA

The address to which the transaction is directed.

gas

QUANTITY

(optional, default: 90000) Integer of the gas provided for the transaction execution. Unused gas will be refunded to the sender. If the specified gas is not enough to execute the transaction, the transaction is reverted.

gasPrice

QUANTITY

(optional, default: 25000000000 Peb) Integer of the gasPrice used for each paid gas.

nonce

QUANTITY

(optional) Integer of a nonce.

value

QUANTITY

Integer of the value sent with this transaction.

input

DATA

The data sent along with the transaction.

humanReadable

Boolean

true if the address is humanReadable, false if the address is not humanReadable. Currently, the value should be false. Human-readable addresses will be supported later.

codeFormat

QUANTITY

The code format of smart contract code. The value 0 indicates EVM.

feePayer

20-byte DATA

The fee payer address of the transaction.

feeRatio

QUANTITY

Fee ratio of the fee payer. If it is 30, 30% of the fee will be paid by the fee payer. 70% will be paid by the sender. The range of fee ratio is 1 ~ 99, if it is out of range, the transaction will not be accepted.

signatures

DATA

(optional - only for klay_sendTransactionAsFeePayer API) An array of signature objects. A signature object contains three fields (V, R, and S). V contains ECDSA recovery id. R contains ECDSA signature r while S contains ECDSA signature s.
