Ethereum Smart Contract Wrapper

Install

------------

```

composer require gri3li/ethereum-smart-contract

```

Usage

-----

Create contract instance:

```php

use gri3li\EthereumSmartContract;

$instance = EthereumSmartContract::createByHost(

    'http://localhost:8545',

    '1', // mainnet

    '0xB8c77482e45F1F44dE1745F52C74426C631bDD52', // contract address

    file_get_contents('path_to_contract_abi_file.json') // abi string

);

```

Reading, for example, erc20 token get balance:

```php

$response = $instance->read('balanceOf', ['0x227390eeba512120c16C239B6556C0992022E961']);

var_dump($response);

/* array(1) {

  'balance' =>

  class phpseclib\Math\BigInteger#47 (2) {

    public $value =>

    string(24) "0x01c3ca8bcdc38115a80020"

    public $engine =>

    string(3) "gmp"

  }

} */

/** @var \BI\BigInteger $balance */

$balance = $response['balance'];

var_dump($balance->toString());

```

Writing, for example, erc20 token send transfer:

```php        

$fromPrivateKey = '4ffe6b52e5f649794dd4f75ed91276ad0dd417ec24cd24ba22802ea50e9d34fd';

$toAddress = '0x227390eeba512120c16C239B6556C0992022E962';

$amount = '1000000000000000000';

$gasLimit = '800000';

$gasPrice = '12000000000';

$txHash = $instance->write('transfer', [$toAddress, $amount], $fromPrivateKey, $gasPrice, $gasLimit);

```
