[Transaction] eth_signTransaction

Signs a transaction that can be submitted to the network at a later time using with eth_sendRawTransaction.

eth_signTransaction will be failed to baobab/cypress network because it is signed in the EN node, which means that the EN must have the key that you want to sign with. Steps to test eth_signTransaction.

• Step 1: Setup a local EN node
• Step 2: Create an account into the EN node
• Step 3: Unlock the account for using in signing

Body

method stringrequired

Default value: eth_signTransaction

Method name

id int64required

Default value: 1

Request ID, Random or Auto incrementation

jsonrpc stringrequired

Default value: 2.0

JSON-RPC Version (2.0)

params

object[]

Array [

from 20-byte DATArequired

The address from which the transaction is sent.

to 20-byte DATA

(not required when creating a new contract) The address to which the transaction is directed.

gas hexrequired

The integer of the gas provided for the transaction's execution. It will return unused gas.

maxFeePerGas hexrequired

The maximum amount to pay for the transaction's execution. Since Klaytn uses a fixed gas price, it must be set to 250 ston (Gpeb in Ethereum).

maxPriorityFeePerGas hexrequired

Gas tip cap for dynamic fee transaction in peb. Since Klaytn uses a fixed gas price, it must be set to 250 ston (Gpeb in Ethereum).

input DATA

(optional) The hash of the method signature and the encoded parameter. It replaces data field, but 'data` field is still supported for backward compatibility.

value hex

(optional) The integer of values sent with this transaction.

nonce hexrequired

The integer of a nonce.
