sendTransaction (VALUE_TRANSFER)

caver.klay.sendTransaction(transactionObject [, callback])

Value Transfer 트랜잭션을 네트워크에 전송합니다.

Parameters

The parameters of sendTransaction are a transaction object and a callback function.

Name	Type	Description
transactionObject	Object	The transaction object to send.
callback	Function	(optional) Optional callback, returns an error object as the first parameter and the result as the second.

VALUE_TRANSFER 유형의 트랜잭션 오브젝트의 구조는 다음과 같습니다.

Name	Type	Description
type	String	Transaction Type. "VALUE_TRANSFER"
from	String	Address of this transaction sender.
to	String	트랜잭션 수신 주소.
value	Number | String | BN | BigNumber	(선택 사항) 트랜잭션으로 전송될 peb 단위의 KLAY.
gas	Number	The maximum amount of gas willing to pay for the transaction (unused gas is refunded).
gasPrice	Number	(optional) Gas price provided by the sender in peb. The gasPrice must be the same as the unitPrice set in the Klaytn node.
nonce	Number	(optional) Integer of a nonce. If omitted, it will be set by caver-js via calling caver.klay.getTransactionCount.

Return Value

The callback will return the 32-byte transaction hash.

PromiEvent: A promise combined event emitter. Will be resolved when the transaction receipt is available. Additionally the following events are available:

• "transactionHash" returns String: Is fired right after the transaction is sent and a transaction hash is available.

• "receipt" returns Object: Is fired when the transaction receipt is available.

• "error" returns Error: Is fired if an error occurs during sending. On an out-of-gas error, the second parameter is the receipt.

Example

const account = caver.klay.accounts.wallet.add('0x{private key}')

// using the promise
caver.klay.sendTransaction({
    type: 'VALUE_TRANSFER',
    from: account.address,
    to: '0x75c3098Be5E4B63FBAc05838DaAEE378dD48098d',
    gas: '300000',
    value: caver.utils.toPeb('1', 'KLAY'),
}).then(function(receipt){
    ...
});

// using the event emitter
caver.klay.sendTransaction({
    type: 'VALUE_TRANSFER',
    from: account.address,
    to: '0x75c3098Be5E4B63FBAc05838DaAEE378dD48098d',
    gas: '300000',
    value: caver.utils.toPeb('1', 'KLAY'),
})
.on('transactionHash', function(hash){
    ...
})
.on('receipt', function(receipt){
    ...
})
.on('error', console.error); // If an out-of-gas error, the second parameter is the receipt.
