[Transaction] eth_sendTransaction

Constructs a transaction with given parameters, signs the transaction with a sender's private key and propagates the transaction to Klaytn network.

eth_sendTransaction 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_sendTransaction.

• 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

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 hex

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

maxFeePerGas hex

maxPriorityFeePerGas hex

(optional, default: 250 ston) 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.
