Partial Fee Delegation

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.

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, feeRatio]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
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:

SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, feeRatio]), feePayer, chainid, 0, 0])
SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, feeRatio, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
feePayerSignatures (a single signature) = [[v, r, s]]
feePayerSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
TxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, feeRatio, txSignatures, feePayer, feePayerSignatures])
TxHash = keccak256(TxHashRLP)

TxTypeFeeDelegatedValueTransferMemoWithRatio

TxTypeFeeDelegatedValueTransferMemoWithRatio is used when a user wants to send KLAY with a specific message. TxTypeFeeDelegatedValueTransferMemoWithRatio 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 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.k

  3. The sender's nonce increases by one.

  4. value KLAY is transferred from the sender to the recipient.

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, feeRatio]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
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:

SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, feeRatio, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

txSignatures (a single signature) = [[v, r, s]]

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

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, humanReadable, feeRatio, codeFormat]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
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:

SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, humanReadable, feeRatio, codeFormat]), feePayer, chainid, 0, 0])
SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, humanReadable, feeRatio, codeFormat, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
feePayerSignatures (a single signature) = [[v, r, s]]
feePayerSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
TxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, humanReadable, feeRatio, codeFormat, txSignatures, feePayer, feePayerSignatures])
TxHash = keccak256(TxHashRLP)

RLP Encoding (Example)

The following shows the result of RLP serialization and the transaction object:

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

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, feeRatio]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
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:

SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, to, value, from, input, feeRatio]), feePayer, chainid, 0, 0])
SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, feeRatio, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

TxHashRLP = type + encode([nonce, gasPrice, gas, to, value, from, input, feeRatio, txSignatures, feePayer, feePayerSignatures])
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.

TxTypeFeeDelegatedCancelWithRatio

TxTypeFeeDelegatedCancelWithRatio cancels the execution of the transaction with the same nonce in the transaction pool. For more details, see TxTypeCancel.

The following changes will apply by this transaction type. 1. The fee payer's balance decreases by the given fee ratio of the amount of the transaction fee. 2. The sender's balance decreases by the remaining transaction fee. 3. The sender's nonce increases by one.

Attributes

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, from, feeRatio]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
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:

SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, from, feeRatio]), feePayer, chainid, 0, 0])
SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, from, feeRatio, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
feePayerSignatures (a single signature) = [[v, r, s]]
feePayerSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
TxHashRLP = type + encode([nonce, gasPricke, gas, from, feeRatio, txSignatures, feePayer, feePayerSignatures])
TxHash = keccak256(TxHashRLP)

TxTypeFeeDelegatedChainDataAnchoringWithRatio

TxTypeFeeDelegatedChainDataAnchoringWithRatio is a fee-delegated transaction, with the ratio, that anchors service chain data to the Klaytn mainchain. Service chains periodically send this type of transaction to the Klaytn mainchain to ensure its security and credibility of data. For more details about the data anchoring, see Anchoring. As it is a fee-delegated transaction with the given ratio as well, the fee payer bears only the given portion of the transaction fee based on the given ratio and the sender pays the rest. Be mindful that it is not allowed to send this transaction via RPC. Currently, this transaction is executed through private p2p channels for security reasons. This transaction does not change the state of the Klaytn blockchain except the sender's nonce being increased by one.

Attributes

RLP Encoding for Signature of the Sender

To make a signature of the sender, RLP serialization should be done like the following:

SigRLP = encode([encode([type, nonce, gasPrice, gas, from, anchoredData, feeRatio]), chainid, 0, 0])
SigHash = keccak256(SigRLP)
Signature = sign(SigHash, <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:

SigFeePayerRLP = encode([encode([type, nonce, gasPrice, gas, from, anchoredData, feeRatio]), feePayer, chainid, 0, 0])
SigFeePayerHash = keccak256(SigFeePayerRLP)
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:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
SenderTxHashRLP = type + encode([nonce, gasPrice, gas, from, anchoredData, feeRatio, txSignatures])
SenderTxHash = keccak256(SenderTxHashRLP)

RLP Encoding for Transaction Hash

To make a transaction hash, RLP serialization should be done like the following:

txSignatures (a single signature) = [[v, r, s]]
txSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
feePayerSignatures (a single signature) = [[v, r, s]]
feePayerSignatures (two signatures) = [[v1, r1, s1], [v2, r2, s2]]
TxHashRLP = type + encode([nonce, gasPrice, gas, from, anchoredData, feeRatio, txSignatures, feePayer, feePayerSignatures])
TxHash = keccak256(TxHashRLP)
