TxTypeFeeDelegatedValueTransferWithRatio
TxTypeFeeDelegatedValueTransferWithRatio is used when a user wants to send KLAY. As Klaytn provides multiple transaction types to make each transaction type serve a single purpose, TxTypeFeeDelegatedValueTransferWithRatio is limited to send KLAY to an externally owned account. Therefore, TxTypeFeeDelegatedValueTransferWithRatio is accepted only if to is an externally owned account. To transfer KLAY to a smart contract account, use TxTypeFeeDelegatedSmartContractExecutionWithRatio instead. The following changes will be made by this transaction type.
1.The fee payer's balance decreases by the given ratio of the transaction fee.
2.The sender's balance decreases by the remaining transaction fee. e.g., If the feeRatio is 30, 30% of the fee will be paid by the fee payer, and the remaining 70% of the fee will be paid by the sender.
3.The sender's nonce increases by one.
4.value KLAY is transferred from the sender to the recipient.

Type
Description
type
uint8 (Go)
The type of TxTypeFeeDelegatedValueTransferWithRatio. This must be 0x0a.
nonce
uint64 (Go)
A value used to uniquely identify a sender’s transaction. If two transactions with the same nonce are generated by a sender, only one is executed.
gasPrice
*big.Int (Go)
A unit price of gas in peb the sender will pay for a transaction fee. The amount of transaction fee is calculated as gas * gasPrice. For example, if the transaction consumes 10 units of gas and gasPrice is 10^18, the transaction fee will be 10 KLAY. See Unit of KLAY.
gas
uint64 (Go)
The maximum amount of gas the transaction is allowed to use.
to
common.Address (Go)
The account address that will receive the transferred value.
value
*big.Int (Go)
The amount of KLAY in peb to be transferred.
from
common.Address (Go)
The address of the sender. For more details, see Signature Validation of Transactions.
feeRatio
uint8 (Go)
Fee ratio of the fee payer. The valid range is between 1 and 99. Zero(0) is not allowed. 100 and above are not allowed as well.

TxTypeFeeDelegatedSmartContractDeployWithRatio
TxTypeFeeDelegatedSmartContractDeployWithRatio deploys a smart contract. The given ratio of the transaction fee is paid by the fee payer. The following changes will be made by this transaction type.
1.The fee payer's balance decreases by the fee ratio of the amount of the transaction fee.
2.The sender's balance decreases by the remaining transaction fee. e.g., If the feeRatio is 30, 30% of the fee will be paid by the fee payer, and the remaining 70% of the fee will be paid by the sender.
3.The sender's nonce increases by one.
4.A smart contract is deployed with the code in input. The deployed address will be returned via contractAddress in the receipt.
5.value KLAY is transferred from the sender to the recipient.
Attributes
Attribute
Type
Description
type
uint8 (Go)
The type of TxTypeFeeDelegatedSmartContractDeployWithRatio. This must be 0x2a.
nonce
uint64 (Go)
A value used to uniquely identify a sender’s transaction. If two transactions with the same nonce are generated by a sender, only one is executed.
gasPrice
*big.Int (Go)
A unit price of gas in peb the sender will pay for a transaction fee. The amount of transaction fee is calculated as gas * gasPrice. For example, if the transaction consumes 10 units of gas and gasPrice is 10^18, the transaction fee will be 10 KLAY. See Unit of KLAY.
gas
uint64 (Go)
The maximum amount of gas the transaction is allowed to use.
to
*common.Address (Go)
The account address that will receive the transferred value. Currently, this value must be nil. Specifying the address will be supported in the future.
value
*big.Int (Go)
The amount of KLAY in peb to be transferred.
from
common.Address (Go)
The address of the sender. For more details, see Signature Validation of Transactions.
input
[]byte (Go)
Data attached to the transaction, used for transaction execution.
humanReadable
bool (Go)
This must be false since human-readable address is not supported yet. If true, the transaction will be rejected.
feeRatio
uint8 (Go)
Fee ratio of the fee payer. The valid range is between 1 and 99. Zero(0) is not allowed. 100 and above are not allowed as well.
codeFormat
uint8 (Go)
The code format of smart contract code. The supported value for now is EVM(0x00) only.
txSignatures
[]{*big.Int, *big.Int, *big.Int} (Go)
The sender's signatures. For more details, see Signature Validation of Transactions.
feePayer
common.Address (Go)
The address of the fee payer.
feePayerSignatures
[]{*big.Int, *big.Int, *big.Int} (Go)
The fee payer's signatures.
RLP Encoding for Signature of the Sender
To make a signature of the sender, RLP serialization should be done like the following:
1
SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, humanReadable, feeRatio, codeFormat]), chainid, 0, 0])
2
SigHash = keccak256(SigRLP)
3
Signature = sign(SigHash, <the sender's private key>)

TxTypeFeeDelegatedSmartContractExecutionWithRatio
TxTypeFeeDelegatedSmartContractExecution executes a smart contract with the given data in input. TxTypeFeeDelegatedSmartContractExecutionWithRatio is accepted only if to is a smart contract account. To transfer KLAY to an externally owned account, use TxTypeFeeDelegatedValueTransferWithRatio instead. The following changes will be made by this transaction type.
1.If to is a smart contract account, the code is executed based on input. Otherwise, this transaction will be rejected.
2.The fee payer's balance decreases by the fee ratio of the amount of the transaction fee.
3.The sender's balance decreases by the remaining transaction fee. e.g., If the feeRatio is 30, 30% of the fee will be paid by the fee payer, and the remaining 70% of the fee will be paid by the sender.
4.The sender's nonce increases by one.
5.If value was provided, value KLAY is transferred from the sender to the to smart contract. The contract should have a payable fallback function to receive KLAY.
Attributes
Attribute
Type
Description
type
uint8 (Go)
The type of TxTypeFeeDelegatedSmartContractExecutionWithRatio. This must be 0x32.
nonce
uint64 (Go)
A value used to uniquely identify a sender’s transaction. If two transactions with the same nonce are generated by a sender, only one is executed.
gasPrice
*big.Int (Go)
A unit price of gas in peb the sender will pay for a transaction fee. The amount of transaction fee is calculated as gas * gasPrice. For example, if the transaction consumes 10 units of gas and gasPrice is 10^18, the transaction fee will be 10 KLAY. See Unit of KLAY.
gas
uint64 (Go)
The maximum amount of gas the transaction is allowed to use.
to
common.Address (Go)
The address of the smart contract account to be executed.
value
*big.Int (Go)
The amount of KLAY in peb to be transferred.
from
common.Address (Go)
The address of the sender. For more details, see Signature Validation of Transactions.
input
[]byte (Go)
Data attached to the transaction, used for transaction execution.
feeRatio
uint8 (Go)
Fee ratio of the fee payer. The valid range is between 1 and 99. Zero(0) is not allowed. 100 and above are not allowed as well.
txSignatures
[]{*big.Int, *big.Int, *big.Int} (Go)
The sender's signatures. For more details, see Signature Validation of Transactions.
feePayer
common.Address (Go)
The address of the fee payer.
feePayerSignatures
[]{*big.Int, *big.Int, *big.Int} (Go)
The fee payer's signatures.
RLP Encoding for Signature of the Sender
To make a signature of the sender, RLP serialization should be done like the following:
1
SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, feeRatio]), chainid, 0, 0])
2
SigHash = keccak256(SigRLP)
3
Signature = sign(SigHash, <the sender's private key>)

RLP Encoding for Signature of the Fee Payer
To make a signature of the fee payer, RLP serialization should be done like the following:
1
SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, feeRatio]), feePayer, chainid, 0, 0])
2
SigFeePayerHash = keccak256(SigFeePayerRLP)
3
SignatureFeePayer = sign(SigFeePayerHash, <the fee payer's private key>)

RLP Encoding for SenderTxHash
To make a SenderTxHash, RLP serialization should be done like the following:
1
txSignatures (a single signature) = [[v, r, s]]
2
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
3
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, feeRatio, txSignatures])
4
SenderTxHash = keccak256(SenderTxHashRLP)
Copied!
RLP Encoding for Transaction Hash
To make a transaction hash, RLP serialization should be done like the following:
1
TxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, feeRatio, txSignatures, feePayer, feePayerSignatures])
2
TxHash = keccak256(TxHashRLP)

TxTypeFeeDelegatedAccountUpdateWithRatio
TxTypeFeeDelegatedAccountUpdateWithRatio updates the key of the given account. The given ratio of the transaction fee is paid by the fee payer. The following changes will take place by this transaction type.
1.The fee payer's balance decreases by the fee ratio of the amount of the transaction fee.
2.The sender's balance decreases by the remaining transaction fee. e.g., If the feeRatio is 30, 30% of the fee will be paid by the fee payer, and the remaining 70% of the fee will be paid by the sender.
3.The sender's nonce increases by one.
4.The account's key is updated with key.
5.Transactions sent from the account afterward will be validated with this key, once this transaction is executed.
