Usage

Create a transaction:

use Web3p\KardiachainTx\Transaction;

// without chainId
$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',
    'to' => '0xd46e8dd67c5d32be8058bb8eb970870f07244567',
    'gas' => '0x76c0',
    'gasPrice' => '0x9184e72a000',
    'value' => '0x9184e72a',
    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);

// with chainId
$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',
    'to' => '0xd46e8dd67c5d32be8058bb8eb970870f07244567',
    'gas' => '0x76c0',
    'gasPrice' => '0x9184e72a000',
    'value' => '0x9184e72a',
    'chainId' => 1,
    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);

// hex encoded transaction
$transaction = new Transaction('0xf86c098504a817c800825208943535353535353535353535353535353535353535880de0b6b3a76400008025a028ef61340bd939bc2195fe537567866003e1a15d3c71ff63e1590620aa636276a067cbe9d8997f761aecb703304b3800ccf555c9f3dc64214b297fb1966a3b6d83');

Sign a transaction:

use Web3p\KardiachainTx\Transaction;

$signedTransaction = $transaction->sign('your private key');

API

Web3p\KardiachainTx\Transaction

sha3

Returns keccak256 encoding of given data.

It will be removed in the next version.

sha3(string $input)

String input

Example

• Encode string.

use Web3p\KardiachainTx\Transaction;

$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',
    'to' => '0xd46e8dd67c5d32be8058bb8eb970870f07244567',
    'gas' => '0x76c0',
    'gasPrice' => '0x9184e72a000',
    'value' => '0x9184e72a',
    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);
$hashedString = $transaction->sha3('web3p');

serialize

Returns recursive length prefix encoding of transaction data.

serialize()

Example

• Serialize the transaction data.

use Web3p\KardiachainTx\Transaction;

$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',
    'to' => '0xd46e8dd67c5d32be8058bb8eb970870f07244567',
    'gas' => '0x76c0',
    'gasPrice' => '0x9184e72a000',
    'value' => '0x9184e72a',
    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);
$serializedTx = $transaction->serialize();

sign

Returns signed of transaction data.

sign(string $privateKey)

String privateKey - hexed private key with zero prefixed.

Example

• Sign the transaction data.

use Web3p\KardiachainTx\Transaction;

$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',

    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);
$signedTx = $transaction->sign($stringPrivateKey);

hash

Returns keccak256 encoding of serialized transaction data.

hash()

Example

• Hash serialized transaction data.

use Web3p\KardiachainTx\Transaction;

$transaction = new Transaction([
    'nonce' => '0x01',
    'from' => '0xb60e8dd61c5d32be8058bb8eb970870f07233155',
    'to' => '0xd46e8dd67c5d32be8058bb8eb970870f07244567',
    'gas' => '0x76c0',
    'gasPrice' => '0x9184e72a000',
    'value' => '0x9184e72a',
    'data' => '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
]);
$hashedTx = $transaction->serialize();
