## Installation

```sh
$ composer require kornrunner/ethereum-token
```

## Usage

To prepare a offline transaction, using `kornrunner/ethereum-offline-raw-tx`

### Transfer

```php
use kornrunner\Ethereum\Token;
use kornrunner\Ethereum\Transaction;

$nonce    = '04';
$gasPrice = '03f5476a00';
$gasLimit = '027f4b';
$to       = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';

$privateKey = 'b2f2698dd7343fa5afc96626dee139cb92e58e5d04e855f4c712727bf198e898';

$token = new Token;
$usdt  = new Token\USDT;

$amount = 20;
$hexAmount = $token->hexAmount($usdt, $amount);
// 0x1312d00

$data = $token->getTransferData($to, $hexAmount);
// 0xa9059cbb0000000000000000000000001a8c8adfbe1c59e8b58cc0d515f07b7225f51c720000000000000000000000000000000000000000000000000000000001312d00

$transaction = new Transaction($nonce, $gasPrice, $gasLimit, $usdt::ADDRESS, '', $data);
$transaction->getRaw($privateKey);
// f8a9048503f5476a0083027f4b94dac17f958d2ee523a2206206994597c13d831ec7b844a9059cbb0000000000000000000000001a8c8adfbe1c59e8b58cc0d515f07b7225f51c720000000000000000000000000000000000000000000000000000000001312d00801ba03e141ea4233ec00bb3a80d7fea5f774b736772851b7bad18453d0f3c6097c42e9fa6eb47b6bead6a76d7db12809e2c916df999d7b99b613fcaa135abd8a0078e
```

### Approve

Approve another address to spend tokens on your behalf:

```php
use kornrunner\Ethereum\Token;
use kornrunner\Ethereum\Transaction;

$token = new Token;
$usdt  = new Token\USDT;

$spender = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';
$amount = 100;
$hexAmount = $token->hexAmount($usdt, $amount);

$data = $token->getApproveData($spender, $hexAmount);
// use $data with Transaction as shown above
```

### Burn

Burn (destroy) tokens:

```php
use kornrunner\Ethereum\Token;
use kornrunner\Ethereum\Transaction;

$token = new Token;
$usdt  = new Token\USDT;

$amount = 50;
$hexAmount = $token->hexAmount($usdt, $amount);

$data = $token->getBurnData($hexAmount);
// use $data with Transaction as shown above
```

### Mint

Mint (create) new tokens to an address:

```php
use kornrunner\Ethereum\Token;
use kornrunner\Ethereum\Transaction;

$token = new Token;
$usdt  = new Token\USDT;

$recipient = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';
$amount = 1000;
$hexAmount = $token->hexAmount($usdt, $amount);

$data = $token->getMintData($recipient, $hexAmount);
// use $data with Transaction as shown above
```

### TransferFrom

Transfer tokens from one address to another using allowance:

```php
use kornrunner\Ethereum\Token;
use kornrunner\Ethereum\Transaction;

$token = new Token;
$usdt  = new Token\USDT;

$from = 'd9040b8a1f12a40511ac1f7b994a21dd08ceac20';
$to = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';
$amount = 50;
$hexAmount = $token->hexAmount($usdt, $amount);

$data = $token->getTransferFromData($from, $to, $hexAmount);
// use $data with Transaction as shown above
```

### Read-Only Functions

For querying token information (generates ABI-encoded call data):

#### BalanceOf

Get the token balance of an address:

```php
use kornrunner\Ethereum\Token;

$token = new Token;
$address = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';

$data = $token->getBalanceOfData($address);
// 0x70a082310000000000000000000000001a8c8adfbe1c59e8b58cc0d515f07b7225f51c72
```

#### Allowance

Check how many tokens a spender is allowed to use:

```php
use kornrunner\Ethereum\Token;

$token = new Token;
$owner = '1a8c8adfbe1c59e8b58cc0d515f07b7225f51c72';
$spender = 'd9040b8a1f12a40511ac1f7b994a21dd08ceac20';

$data = $token->getAllowanceData($owner, $spender);
// 0x...
```

#### TotalSupply

Get the total supply of tokens:

```php
use kornrunner\Ethereum\Token;

$token = new Token;

$data = $token->getTotalSupplyData();
// 0x18160ddd
```
