LEGACY 유형의 트랜잭션 오브젝트의 구조는 다음과 같습니다.

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.
