transaction.sign

transaction.sign(keyring [, index] [, hasher])
Signs the transaction as a transaction sender with the private key(s) in the keyring and appends signatures in the transaction object.
For Account Update transaction, use roleAccountUpdateKey, or otherwise, use roleTransactionKey in RoleBasedKeyring. If the user has not defined an index, transaction.sign signs the transaction using all the private keys used by the role. If index is defined, the transaction.sign signs the transaction using only one private key at the given index.
Parameters
Name
Type
Description
keyring
object | string
A private key string (KlaytnWalletKey format is also allowed) or an instance of Keyring (SingleKeyring, MultipleKeyring or RoleBasedKeyring). If a private key string or a KlaytnWalletKey is passed as a parameter, the keyring instance is created internally.
index
number
(optional) The index of the private key you want to use. The index must be less than the length of the array of the private keys defined for each role. If an index is not defined, this method will use all the private keys.
hasher
Function
(optional) The hash function to get the hash of the transaction.
Return Value
Promise returning object: The signed transaction.
Type
Description
object
An instance of signed Transaction. The signature is appended to the transaction.signatures.

transaction.signAsFeePayer

transaction.signAsFeePayer(keyring [, index] [, hasher])
Signs the transaction as a transaction fee payer and appends feePayerSignatures in the transaction object with the private key(s) in the keyring.
For signing a transaction as a fee payer, use roleFeePayerKey in keyring. If the user has not defined an index, transaction.signAsFeePayer signs the transaction using all the private keys used by the role. If index is defined, the transaction.signAsFeePayer signs the transaction using only one private key at the given index.
If the transaction.feePayer is not defined, the address of the given keyring is set to transaction.feePayer.
If the keyring to be used for signing the transaction was added to caver.wallet, you can use caver.wallet.signAsFeePayer.
NOTE This function works only for "fee-delegated" transactions or "fee-delegated with ratio" transactions.

Returns a rawTransaction string (a RLP-encoded transaction string). This function is same with transaction.getRLPEncoding.
Return Value
Type
Description
string
A RLP-encoded transaction string.
Example
> transaction.getRawTransaction()
'0x09f885018505d21dba00830f4240947b65b75d204abed71587c9e519a89277766ee1d00a9404bb86a1b16113ebe8f57071f839b002cbcbf7d0f847f845820feaa068e56f3da7fbe7a86543eb4b244ddbcb13b2d1cb9adb3ee8a4c8b046821bc492a068c29c057055f68a7860b54184bba7967bcf42b6aae12beaf9f30933e6e730c280c4c3018080'

transaction.getTransactionHash

transaction.getTransactionHash()
Returns a transactionHash.
For information on how to make the transaction hash for each transaction type, see Klaytn Design - Transactions.
Return Value
Type
Description
string
A transactionHash.
Example
> transaction.getTransactionHash()
'0x8ac53afbba014201b02398545653683fe0536c49707fe302c59423012c0e8697'

transaction.getSenderTxHash

transaction.getSenderTxHash()
Returns a senderTxHash of transaction.
The senderTxHash is a hash of the transaction except for the fee payer's address and signature, so transactionHash and senderTxHash are the same for basic transactions.
For information on how to make the senderTxHash for each transaction type, see Klaytn Design - Transactions.
Return Value
Type
Description
string
A senderTxHash.
Example
> transaction.getSenderTxHash()
'0xb61cc1ddadb6f2ec34c9f9e6a7b6cf0a606422654d649d998587c77daa3c31fe'

transaction.getRLPEncodingForSignature

transaction.getRLPEncodingForSignature()
Returns a RLP-encoded transaction string for making the signature of the transaction sender. Note that the returned RLP-encoded transaction string is not added with the signature and rather is used to generate this signature.
For information on how to make a RLP-encoded transaction string to generate the transaction sender's signature for each transaction type, see Klaytn Design - Transactions.
Return Value
Type
Description
string
A RLP-encoded transaction string without any signature attached.
Example
> transaction.getRLPEncodingForSignature()
'0xf83fb838f709018505d21dba00830f4240947b65b75d204abed71587c9e519a89277766ee1d00a9404bb86a1b16113ebe8f57071f839b002cbcbf7d08207e38080'

transaction.getRLPEncodingForFeePayerSignature

transaction.getRLPEncodingForFeePayerSignature()
Returns a RLP-encoded transaction string for making the signature of the fee payer. Note that the returned RLP-encoded transaction string is not added with the signature and rather is used to generate this signature.
For information on how to make a RLP-encoded transaction string to generate the fee payer's signature for each transaction type, see Klaytn Design - Transactions.
NOTE This function works only for "fee-delegated" transactions or "fee-delegated with ratio" transactions.
Return Value
Type
Description
string
A RLP-encoded transaction string without any signature attached.
Example
> transaction.getRLPEncodingForFeePayerSignature()
'0xf840b838f709018505d21dba00830f4240947b65b75d204abed71587c9e519a89277766ee1d00a9404bb86a1b16113ebe8f57071f839b002cbcbf7d0808207e38080'

transaction.fillTransaction

transaction.fillTransaction()
Fills in the optional variables in transaction.
If the gasPrice, nonce, or chainId of the transaction are not defined, this method asks the default values for these optional variables and preset them by sending JSON RPC call to the connected Klaytn Node.
Use caver.rpc.klay.getGasPrice to get gasPrice, caver.rpc.klay.getTransactionCount to get nonce and caver.rpc.klay.getChainId call to get chainId.
Return Value
Promise returning void
Example
> transaction.fillTransaction()

transaction.recoverPublicKeys

transaction.recoverPublicKeys()
Recovers the public key strings from signatures field.
NOTE transaction.recoverPublicKeys is supported since caver-js v1.6.3.
Return Value
Type
Description
Array
An array containing public keys recovered from signatures.
Example
> transaction.recoverPublicKeys()
[
