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

Return Value

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

Example

// Create AccountForUpdate for AccountKeyLegacy
> caver.klay.accounts.createAccountForUpdateWithLegacyKey('0x5B4EF8e2417DdE1b9B80BcfC35d1bfeF3D7234ef')
AccountForUpdate {
    address: '0x5B4EF8e2417DdE1b9B80BcfC35d1bfeF3D7234ef',
    keyForUpdate: { legacyKey: true } 
}

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

Return Value

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

Example

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

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:

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 FEEDELEGATED 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

Return Value

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

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.
