sendTransaction (Legacy)

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

트랜잭션을 네트워크로 보냅니다.

참고: AccountKeyLegacy 가 있는 계정 만, sendTransaction 이 가능합니다.

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.

LEGACY 유형의 트랜잭션 오브젝트의 구조는 다음과 같습니다.

Name	Type	Description
from	String	Address of this transaction sender.
to	String	(선택 사항) 메시지 수신자 주소이며, 트랜잭션이 컨트랙트 생성 트랜잭션일 경우 수신자 주소가 입력되지 않습니다.
value	Number | String | BN | BigNumber	(선택 사항) 트랜잭션으로 전송할 peb 단위로 환산된 KLAY입니다. 컨트랙트 생성 트랜잭션일 경우 (생성 함수가 KLAY를 받을 수 있게 설정되었다면) 컨트랙트가 생성 시 보유하는 KLAY입니다.
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.
data	String	(선택 사항) 컨트랙트의 함수를 호출할 수 있는 데이터가 담긴 ABI byte string 또는, 컨트랙트 생성 트랜잭션일 경우 컨트랙트를 초기화(initialize)하는 코드입니다.
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}')

var code = "0x603d80600c6000396000f3007c01000000000000000000000000000000000000000000000000000000006000350463c6888fa18114602d57005b6007600435028060005260206000f3";

// using the callback
caver.klay.sendTransaction({
    from: account.address,
    data: code // deploying a contracrt
}, function(error, hash){
    ...
});

// using the promise
caver.klay.sendTransaction({
    from: account.address,
    to: '0x11f4d0A3c12e86B4b5F39B213F7E19D048276DAe',
    value: '1000000000000000'
})
.then(function(receipt){
    ...
});

// using the event emitter
caver.klay.sendTransaction({
    from: account.address,
    to: '0x11f4d0A3c12e86B4b5F39B213F7E19D048276DAe',
    value: '1000000000000000'
})
.on('transactionHash', function(hash){
    ...
})
.on('receipt', function(receipt){
    ...
})
.on('error', console.error); // If an out-of-gas error, the second parameter is the receipt.
