Cancel

sendTransaction (CANCEL)

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

Sends a Cancel transaction to the network.

Parameters

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

A transaction object of type CANCEL has the following structure:

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: 'CANCEL',
    from: account.address,
    nonce: 7, // It specifies target transaction having the same nonce to cancel.
    gas: '300000',
})
.then(function(receipt){
    ...
});

// using the event emitter
caver.klay.sendTransaction({
    type: 'CANCEL',
    from: account.address,
    nonce: 7, // It specifies target transaction having the same nonce to cancel.
    gas: '300000',
})
.on('transactionHash', function(hash){
    ...
})
.on('receipt', function(receipt){
    ...
})
.on('error', console.error); // If an out-of-gas error, the second parameter is the receipt.

// using the promise
const { rawTransaction: senderRawTransaction } = await caver.klay.accounts.signTransaction({
  type: 'FEE_DELEGATED_CANCEL',
  from: sender.address,
  nonce: 7, // It specifies target transaction having the same nonce to cancel.
