createWithAccountKey

caver.klay.accounts.createWithAccountKey(address, accountKey)

Creates an instance of Account with the given AccountKey. Account is for managing an account's address and AccountKey.

NOTE This is merely a data structure used in caver-js. This method does not create or update an account in the Klaytn network. NOTE caver.klay.accounts.createWithAccountKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
address	String	Address of an Account.
accountKey	String | Array | Object	An AccountKey instance (AccountKeyPublic, AccountKeyMultiSig or AccountKeyRoleBased) or a data structure that contains the key info (a private key string, an array of private key strings or an object that defines the key for each role).

Return Value

Object - An Account instance is returned, with the following properties:

Name	Type	Description
address	String	The address of the account.
privateKey	String	Default key string of accountKey that the account has. This property is left for backward compatibility. privateKey only represents the default key of accountKey, so using privateKey to sign or send a transaction is not recommended. It is recommended to use transactionKey, updateKey, or feePayerKey in context.
accountKeyType	String	Type of accountKey the account has. This can be AccountKeyPublic, AccountKeyMultiSig, or AccountKeyRoleBased
accountKey	Object	The key of the account. This is AccountKeyPublic, AccountKeyMultiSig or AccountKeyRoleBased.
keys	String | Array | Object	All keys inside accountKey that the Account has. For AccountKeyPublic, this is a single private key string; for AccountKeyMultiSig, this returns an array containing all the private key strings. In the case of AccountKeyRoleBased, an object with keys associated with each role is returned.
transactionKey	String | Array	Key used for the RoleTransaction. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so transactionKey holds the same value as keys.
updateKey	String | Array	Key used for the RoleAccountUpdate. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so updateKey holds the same value as keys.
feePayerKey	String | Array	Key used for RoleFeePayer. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so feePayerKey holds the same value as keys.
signTransaction(tx [, callback])	Function	The function to sign transactions. See caver.klay.accounts.signTransaction.
sign(data)	Function	The function to sign transactions. See caver.klay.accounts.sign.
encrypt	Function	The function to encrypt an Account with given password.
getKlaytnWalletKey	Function	The function to get Klaytn Wallet Key.

createAccountKey

caver.klay.accounts.createAccountKey(key)

Creates an instance of AccountKeyPublic, AccountKeyMultiSig, or AccountKeyRoleBased depending on the type of parameter.

AccountKey is a data structure for managing keys in caver-js. Use AccountKeyPublic if you want to use a single private key, AccountKeyMultiSig if you want to use multiple private keys, or AccountKeyRoleBased if you want to use a different key for each role.

NOTE caver.klay.accounts.createAccountKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
key	String | Array | Object	Key for generating AccountKey. If key is a single private key string, an AccountKeyPublic instance is created. If key is an array containing multiple private key strings, an AccountKeyMultiSig instance is created. If key is an object defining a key (a private key string or an array of private key strings) for each role, an AccountKeyRoleBased instance is created. AccountKeyRoleBased instance can have AccountKeyPublic or AccountKeyMultiSig for each role.

Return Value

Object - An AccountKeyPublic, AccountKeyMultiSig or AccountKeyRoleBased instance is returned with the following properties:

Name	Type	Description
type	String	The type of AccountKey instance.
defaultKey	String	Default private key of AccountKey. The default private key represents a single private key string defined for AccountKeyPublic, and a private key string in the zeroth index of the array if AccountKeyMultiSig. For AccountKeyRoleBased, it represents the defaultKey of the first found AccountKey, where the AccountKey is searched in the following order: transactionkey, updateKey, feePayerKey.
keys	String | Array | Object	All private keys defined inside the AccountKey instance. For AccountKeyPublic, this is a single private key string; for AccountKeyMultiSig, this returns an array containing all the private key strings. In the case of AccountKeyRoleBased, an object with keys associated with each role is returned.
transactionKey	String | Array	Key used for the RoleTransaction. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so transactionKey holds the same value as keys.
updateKey	String | Array	Key used for the RoleAccountUpdate. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so updateKey holds the same value as keys.
feePayerKey	String | Array	Key used for RoleFeePayer. AccountKeyPublic or AccountKeyMultiSig are not bound to any roles, so feePayerKey holds the same value as keys.

Example

// Create an AccountKeyPublic
> caver.klay.accounts.createAccountKey('0x{private key}')
AccountKeyPublic {
    _key: '0x{private key}'

createAccountForUpdateWithPublicKey

caver.klay.accounts.createAccountForUpdateWithPublicKey(address, keyForUpdate, options)

Creates an instance of AccountForUpdate with the public key of the new key to update.

AccountForUpdate can be used in the account update transaction object (ACCOUNT_UPDATE, FEE_DELEGATED_ACCOUNT_UPDATE, or FEE_DELEGATED_ACCOUNT_UPDATE_WITH_RATIO) as a key. If you want to know how to use AccountForUpdate in the transaction, see Account update with AccountForUpdate.

NOTE caver.klay.accounts.createAccountForUpdateWithPublicKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
address	String	Address of an Account.
keyForUpdate	String | Array | Object	The public-key of the new key to update. This value is a single public-key string when the key is AccountKeyPublic, an array of public-key strings when AccountKeyMultiSig, an object when the key is AccountKeyRoleBased.
options	Object	An optional object containing the threshold and weight. This is required when using AccountKeyMultiSig. If you use AccountkeyMultiSig as one of the keys in AccountKeyRoleBased, specify the role of the threshold and weight. The usage is shown in the example below.

Return Value

Object - An AccountForUpdate instance, see caver.klay.accounts.createAccountForUpdate.

createAccountForUpdateWithLegacyKey

caver.klay.accounts.createAccountForUpdateWithLegacyKey(address)

Creates an AccountForUpdate instance to update the account's key with AccountKeyLegacy. Make sure you have a private key that matches your account address before updating to AccountKeyLegacy.

AccountForUpdate can be used in the account update transaction object (ACCOUNT_UPDATE, FEE_DELEGATED_ACCOUNT_UPDATE, or FEE_DELEGATED_ACCOUNT_UPDATE_WITH_RATIO) as a key. If you want to know how to use AccountForUpdate in the transaction, see Account update with AccountForUpdate.

NOTE caver.klay.accounts.createAccountForUpdateWithLegacyKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
address	String	Address of an Account.

Return Value

Object - An AccountForUpdate instance, see caver.klay.accounts.createAccountForUpdate.

Example

// Create AccountForUpdate for AccountKeyLegacy
> caver.klay.accounts.createAccountForUpdateWithLegacyKey('0x5B4EF8e2417DdE1b9B80BcfC35d1bfeF3D7234ef')

}

createAccountForUpdateWithFailKey

caver.klay.accounts.createAccountForUpdateWithFailKey(address)

Creates an AccountForUpdate instance to update the account's key with AccountKeyFail. Transactions sent by an account with AccountKeyFail always fail in the validation process.

AccountForUpdate can be used in the account update transaction object (ACCOUNT_UPDATE, FEE_DELEGATED_ACCOUNT_UPDATE, or FEE_DELEGATED_ACCOUNT_UPDATE_WITH_RATIO) as a key. If you want to know how to use AccountForUpdate in the transaction, see Account update with AccountForUpdate.

NOTE caver.klay.accounts.createAccountForUpdateWithFailKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
address	String	Address of an Account.

Return Value

Object - An AccountForUpdate instance, see caver.klay.accounts.createAccountForUpdate.

Example

// Create AccountForUpdate for AccountKeyFail
> caver.klay.accounts.createAccountForUpdateWithFailKey('0x5B4EF8e2417DdE1b9B80BcfC35d1bfeF3D7234ef')
AccountForUpdate {

    keyForUpdate: { failKey: true } 
}

signTransaction

caver.klay.accounts.signTransaction(tx [, privateKey] [, callback])

Signs a Klaytn transaction with a given private key.

Since caver-js v1.2.0, this method takes an RLP-encoded transaction as an input as well as a plain transaction object. See caver.klay.sendTransaction for the various types of transaction object. This method basically signs as a sender. If you want to sign as a fee-payer, we recommend to use caver.klay.accounts.feePayerSignTransaction. But, fee-payers can still sign using this method by passing an object, {senderRawTransaction: rawTransaction, feePayer: feePayerAddress}, as tx. senderRawTransaction must be a FEE_DELEGATED_ type transaction.

Also since caver-js v1.2.0, signTransaction keeps the existing signatures/feePayerSignatures in the input transaction and appends the signature(s) of the signer to it.

See Sending a Transaction with multiple signer for how to combine multiple users' signatures into a single rawTransaction.

Parameters

Name	Type	Description
tx	String | Object	Transaction object or RLP-encoded transaction string (rawTransaction). The properties of a transaction object varies depending on the transaction type. For the description of each transaction type, see caver.klay.sendTransaction.
privateKey	String | Array	(optional) The private key to sign with.
callback	Function	(optional) Optional callback, returns an error object as the first parameter and the result as the second.

NOTE The privateKey parameter has been changed to an optional parameter since caver-js v1.2.0-rc.3. Also, privateKey parameter supports array of private key strings since caver-js v1.2.0-rc.3. If you do not pass a privateKey, either from or feePayer account must exist in caver.klay.accounts.wallet to sign the transaction. If an array of privateKeys are provided, the transaction is signed with all the keys inside the array.

NOTE The tx parameter accepts an RLP-encoded transaction since caver-js v1.2.0.

Return Value

Promise returning Object: The RLP encoded signed transaction. The object properties are as follows:

Name	Type	Description
messageHash	String	The hash of the given message.
r	String	ECDSA signature r.
s	String	ECDSA signature s.
v	String	ECDSA recovery id.
rawTransaction	String	The RLP encoded transaction, ready to be send using caver.klay.sendSignedTransaction.
txHash	32-byte String	Hash of the transaction.
senderTxHash	32-byte String	Hash of a transaction that is signed only by the sender. See SenderTxHash
signatures	Array	(optional) An array of the sender's signature(s).
feePayerSignatures	Array	(optional) An array of the fee payer's signature(s).

NOTE The signatures and feePayerSignatures properties have been added since caver-js v1.2.0-rc.3. If the sender signs the transaction, the signature array is returned in signatures. If the fee payer signs, the signature array is returned in feePayerSignatures.

NOTE The txHash and senderTxHash in the result object may not be the final values. If another sender signature is added, txHash and senderTxHash will change. If a fee-payer signature is added, txHash will change.

feePayerSignTransaction

caver.klay.accounts.feePayerSignTransaction(tx, feePayerAddress [, privateKey] [, callback])

Signs a transaction as a fee payer.

Fee payers can sign on a FEE_DELEGATED_ transaction. A transaction object or an RLP-encoded transaction can be passed as an argument.

If privateKay is not given, feePayerKey of the fee payer's account inside the caver-js in-memory wallet is used.

feePayerSignTransaction keeps the existing signatures/feePayerSignatures in the input transaction and appends the fee-payer signature(s) to it.

See Sending a Transaction with multiple signer for how to combine multiple users' signatures into a single rawTransaction.

NOTE caver.klay.accounts.feePayerSignTransaction is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
tx	String | Object	Transaction object or RLP-encoded transaction string (rawTransaction). The properties of a transaction object varies depending on the transaction type. For the description of each transaction type, see caver.klay.sendTransaction.
feePayerAddress	String	The address of fee payer.
privateKey	String | Array	(optional) The private key to sign with.
callback	Function	(optional) Optional callback, returns an error object as the first parameter and the result as the second.

Return Value

Promise returning Object: The RLP encoded signed transaction. The object properties are as follows:

Name	Type	Description
messageHash	String	The hash of the given message.
v	String	ECDSA recovery id.
r	String	ECDSA signature r.
s	String	ECDSA signature s.
rawTransaction	String	The RLP encoded transaction, ready to send using caver.klay.sendSignedTransaction.
txHash	32-byte String	Hash of the transaction.
senderTxHash	32-byte String	Hash of a transaction that is signed only by the sender. See SenderTxHash
feePayerSignatures	Array	An array of the fee payer's signature(s).

NOTE The txHash and senderTxHash in the result object may not be the final values. If another sender signature is added, txHash and senderTxHash will change. If a fee-payer signature is added, txHash will change.

combineSignatures

caver.klay.accounts.combineSignatures(rawTransactions)

Combines the array of RLP encoded transaction strings into a single RLP encoded transaction string. RLP encoded transaction string that you want to combine must all have signed the same transaction.

combineSignatures removes duplicates in signatures or feePayerSignatures.

NOTE caver.klay.accounts.combineSignatures is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
rawTransactions	Array	An array of RLP encoded transaction strings (rawTransaction).

Return Value

Promise returning Object: An RLP encoded transaction. The object properties are as follows:

Name	Type	Description
rawTransaction	String	An RLP encoded transaction, ready to send using caver.klay.sendSignedTransaction.
txHash	32-byte String	Hash of the transaction.
senderTxHash	32-byte String	Hash of a transaction that is signed only by the sender. See SenderTxHash
signatures	Array	(optional) All signatures in the combined RLP encoded transaction (rawTransaction). If there are no signatures, the signatures property is not returned in the result object.
feePayerSignatures	Array	(optional) All feePayerSignatures in the combined RLP encoded transaction (rawTransaction). If there are no feePayerSignatures, the feePayerSignatures property is not returned in the result object.

NOTE The txHash and senderTxHash in the result object may not be the final values. If another sender signature is added, txHash and senderTxHash will change. If a fee-payer signature is added, txHash will change.

Example

getRawTransactionWithSignatures

caver.klay.accounts.getRawTransactionWithSignatures(tx [, callback])

Returns a signed RLP encoded transaction string from a given transaction object. The transaction object should provide the signatures and feePayerSignatures.

NOTE caver.klay.accounts.getRawTransactionWithSignatures is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
tx	Object	A transaction object that includes signatures and feePayerSignatures. The properties of a transaction object varies depending on the transaction type. For the description of each transaction type, see caver.klay.sendTransaction.

Return Value

Promise returning Object: An RLP encoded transaction. The object properties are as follows:

Name	Type	Description
rawTransaction	String	An RLP encoded transaction, ready to send using caver.klay.sendSignedTransaction.
txHash	32-byte String	Hash of the transaction.
senderTxHash	32-byte String	Hash of a transaction that is signed only by the sender. See SenderTxHash
signatures	Array	(optional) All signatures in the RLP encoded transaction (rawTransaction). If there are no signatures, the signatures property is not returned in the result object.
feePayerSignatures	Array	(optional) All feePayerSignatures in the RLP encoded transaction (rawTransaction). If there are no feePayerSignatures, the feePayerSignatures property is not returned in the result object.

NOTE The txHash and senderTxHash contained in the result object may not be final values. If the signature of the sender is added, txHash and senderTxHash will be different. If the signature of the fee payer is added, the txHash will be different.

encrypt

caver.klay.accounts.encrypt(encryptTarget, password [, options])

Encrypts an account to the Klaytn keystore standard. For more information, please refer to KIP-3.

NOTE Since caver-js v1.2.0, caver.klay.accounts.encrypt encrypts using the keystore v4 standard to encrypt various AccountKey types (AccountKeyPublic, AccountKeyMultiSig, AccountKeyRoleBased). If you want to encrypt an account using keystore v3, please use caver.klay.accounts.encryptV3.

Parameters

Name	Type	Description
encryptTarget	String | Array | Object	A private key or a Klaytn wallet key to encrypt. Since caver-js v1.2.0, encryptTarget also can be an instance of Account or AccountKey (AccountKeyPublic, AccountKeyMultiSig, or AccountKeyRoleBased), an array of private key strings or an object that defines the keys by role.
password	String	The password used for encryption.
options	Object	(optional) The options parameter allows you to specify the values to use when using encrypt. You can also use the options object to encrypt decoupled accounts. See the example below for usage of options.

NOTE If account address cannot be extracted from encryptTarget (when AccountKeyMultiSig, AccountKeyRoleBased, an array of private key strings or an object that defines the keys by role) or if the account's private key is decoupled from address, you must specify the address in the options object.

NOTE: There are two ways to encrypt the private key when an account has a decoupled private key from the address.

1. Use the KlaytnWalletKey format with the privateKey parameter.

2. Use the options.address to send the address as a parameter.

Return Value

Type	Description
Object	The encrypted keystore JSON. Since caver-js v1.2.0, keystore v4 is used. The example below illustrates both keystore v3 and v4.

encryptV3

caver.klay.accounts.encryptV3(encryptTarget, password [, options])

Encrypts an account to the Klaytn keystore v3 standard.

NOTE caver.klay.accounts.encryptV3 is supported since caver-js v1.3.2-rc.1.

Parameters

Name	Type	Description
encryptTarget	String | Object	A private key, a Klaytn wallet key, or an instance of Account or AccountKeyPublic to encrypt.
password	String	The password used for encryption.
options	Object	(optional) The options parameter allows you to specify the values to use when using encrypt. You can also use the options object to encrypt decoupled accounts. See the third example below for usage of options.

NOTE: There are two ways to encrypt the private key when an account has a decoupled private key from the address.

1. Use the KlaytnWalletKey as encryptTarget parameter.

2. Use the address as options.address parameter to send the address as one of the parameters. See the third example below for the usage.

Return Value

Type	Description
Object	The encrypted keystore v3 JSON.

Return the Klaytn wallet key for the account on the wallet of caver-js.

Parameters

Name	Type	Description
indexOrAddress	Number|String	An index in the wallet address list, an address in hexadecimal. The given value should exist in the caver-js wallet.

Return Value

Type	Description
String	KlaytnWalletKey that matches the account. This value allows you to log in to the wallet.

Example

// With non-human-readable address
> caver.klay.accounts.wallet.getKlaytnWalletKey(0)
'0x{private key}0x{type}0x{address in hex}'

// With index of wallet list
> caver.klay.accounts.wallet.getKlaytnWalletKey(1)
'0x{private key}0x{type}0x{address in hex}'

// With an address in hexadecimal
> caver.klay.accounts.wallet.getKlaytnWalletKey('0xa9d40b07a6d06e7b7af6cf9a17fb107c9fc7fe58')
'0x{private key}0x{type}0x{address in hex}'

wallet.updatePrivateKey

caver.klay.accounts.wallet.updatePrivateKey(privateKey, address)

Update the account's private key information stored in the wallet.

NOTE: This function only changes the information stored in the wallet of caver-js. This function has no effect on the key information stored on the Klaytn network. Keys in the Klaytn network can be changed by sending a 'ACCOUNT_UPDATE' transaction.

NOTE updatePrivateKey only works if the account's accountKey is AccountKeyPublic. Since caver-js v1.2.0 supports AccountKeys (AccountKeyPublic, AccountKeyMultiSig, AccountKeyRoleBased), privateKey becomes a read-only property referencing the defaultKey of the accountKey. This method does not directly update the privateKey, instead update the accountKey. This method is maintained for backward-compatibility. It is now recommended to use more generic caver.klay.accounts.wallet.updateAccountKey.

Parameters

Name	Type	Description
privateKey	String	New private key to be used for updates.
address	String	The account address in the wallet.

Return Value

Type	Description
Object	Account instance with the new accountKey. The Account instance lives in-memory caver-js wallet.

Example

> caver.klay.accounts.wallet.updatePrivateKey('0x{private key}', '0xf2e2565629c7763dc0b595e8e531a31371a95f95');

    accountKey: [Getter/Setter],
    privateKey: [Getter/Setter],
    signTransaction: [Function: signTransaction],

    encrypt: [Function: encrypt],
    getKlaytnWalletKey: [Function: getKlaytnWalletKey],

}

wallet.updateAccountKey

caver.klay.accounts.wallet.updateAccountKey(address, accountKey)

Update the account's account key information stored in the wallet. When you update your account's accountKey, privateKey is updated as well to the defaultKey of the new accountKey.

If the accountKey parameter is a single private key string, the account's accountKey is updated with an AccountKeyPublic instance. If the accountKey parameter is an array with multiple private key strings, the account's accountKey is updated with an AccountKeyMultiSig instance. If the accountKey parameter is an object whose keys are defined by roles, the account's accountKey is updated with an AccountKeyRoleBased instance.

NOTE: This function only changes the information stored in the wallet of caver-js. This function has no effect on the key information stored on the Klaytn network. Keys in the Klaytn network can be changed by sending a 'ACCOUNT_UPDATE' transaction.

NOTE caver.klay.accounts.wallet.updateAccountKey is supported since caver-js v1.2.0.

Parameters

Name	Type	Description
address	String	The account address in the wallet.
accountKey	String | Array | Object	An AccountKey instance (AccountKeyPublic, AccountKeyMultiSig or AccountKeyRoleBased) or a data structure that contains the key info (a private key string, an array of private key strings or an object that defines the key for each role).

Return Value

Type	Description
Object	Account instance with the new accountKey. The Account instance lives in-memory caver-js wallet.

Example

// Update to AccountKeyPublic with a private key string
> caver.klay.accounts.wallet.updateAccountKey('0xf2e2565629c7763dc0b595e8e531a31371a95f95', '0x{private key}')
