# Создание транзакции

В данной статье мы будем использоваться этот кошелек для примера:

```c
Address: 0x026A25EfbcEFb2e481d005E4F00Ccced0AF511FF
Private Key: 0x1c1a49fea9a4ede1dc8e582639f498d41fa3c4a9e2ab2b9d740a4a3ec14e1cbf
```

## **Уровень-1 (Layer-1)**

Единственная транзакция, которая совершается на Уровне-1 – это депозит. Она имеет два подтипа `DepositETH и DepositERC20`.

### **ABIs**

```cpp
[
  {
    "constant": false,
    "inputs": [
      {
        "internalType": "contract IERC20",
        "name": "_token",
        "type": "address"
      },
      {
        "internalType": "uint104",
        "name": "_amount",
        "type": "uint104"
      },
      {
        "internalType": "address",
        "name": "_franklinAddr",
        "type": "address"
      }
    ],
    "name": "depositERC20",
    "outputs": [],
    "payable": false,
    "stateMutability": "nonpayable",
    "type": "function"
  },
  {
    "constant": false,
    "inputs": [
      {
        "internalType": "address",
        "name": "_franklinAddr",
        "type": "address"
      }
    ],
    "name": "depositETH",
    "outputs": [],
    "payable": true,
    "stateMutability": "payable",
    "type": "function"
  }
]
```

### **Депозит ETH**

Пример кода:

```csharp
import { Wallet, Contract, utils } from 'ethers'

const contract = new Contract('0x8ECa806Aecc86CE90Da803b080Ca4E3A9b8097ad', ABI, wallet)
const wallet = new Wallet('0x1c1a49fea9a4ede1dc8e582639f498d41fa3c4a9e2ab2b9d740a4a3ec14e1cbf')

async function depositETH(amount) {
  const tx = await contract.depositETH(wallet.address, {
    value: utils.parse(amount)
  })
  return tx
}

// deposit 1 ETH
depositETH('1').then(console.log)
```

### **Депозит ERC20**

Как и в других проектах вы должны подтвердить основной адрес контракта ZKSwap, чтобы внести свои токенты ERC20 на депозит. Будьте осторожны с токенами, у которых есть ограничения (Подробнее см. [здесь](https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729)). 

Пример кода:

```csharp
import { Wallet, Contract, utils } from 'ethers'

const contract = new Contract('0x8ECa806Aecc86CE90Da803b080Ca4E3A9b8097ad', ABI, wallet)
const wallet = new Wallet('0x1c1a49fea9a4ede1dc8e582639f498d41fa3c4a9e2ab2b9d740a4a3ec14e1cbf')

async function depositERC20(amount, tokenAddress) {
  const tokenContract = new Contract(tokenAddress, ERC20_ABI, wallet)
  // check allowance
  const allowance = await tokenContract.allowance(wallet.address, MAIN_CONTRACT_ADDRESS)
  let nonce
  if (allowance.lt(utils.parse(amount)) {
    // approve
    const MAX_AMOUNT = '0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff'
    const approveTx = await tokenContract.allow(MAIN_CONTRACT_ADDRESS, MAX_AMOUNT)
    nonce = approveTx.nonce + 1
  }
  const tx = await contract.depositERC20(tokenAddress, utils.parse(amount), wallet.address, {
    nonce
  })
  return tx
}

// deposit 100 ZKS
depositERC20('100', '0xe4815ae53b124e7263f08dcdbbb757d41ed658c6').then(console.log)
```

### **Уровень-2**

При отправке транзакции на ZKSwap через API необходимо заполнить три поля: `tx`, `signature` и `fastProcessing`. Далее по тексту `Signed Transaction` относиться к полю `tx`, а ETH Signature относится к полю `signature`.

### **Приватный ключ**

Подпишите следующее сообщение приватным ключом Уровня 1, чтобы получить сид фразу Уровня 2. И используйте [криптографические библиотеки zkSync](https://zksync.io/api/sdk/crypto.html), чтобы получить приватный ключ.

{% tabs %}
{% tab title="Plain Text" %}

```csharp
Access ZKSwap account.

Only sign this message for a trusted client!
```

{% endtab %}

{% tab title=" JavaScript" %}

```javascript
const msg = 'Access ZKSwap account.\n\nOnly sign this message for a trusted client!'
```

{% endtab %}
{% endtabs %}

Вот полный пример получения приватного ключа с помощью [zksync-crypto](https://www.npmjs.com/package/zksync-crypto) в JavaScript.

```csharp
import { Wallet, Contract, utils } from 'ethers'
import { privateKeyFromSeed, private_key_to_pubkey_hash } from 'zksync-crypto'

const wallet = new Wallet('0x1c1a49fea9a4ede1dc8e582639f498d41fa3c4a9e2ab2b9d740a4a3ec14e1cbf')

async function getPrivateKey() {
    const msg = 'Access ZKSwap account.\n\nOnly sign this message for a trusted client!'
    const signature = await wallet.signMessage(msg)
    const seed = utils.arrayify(signature)

    // Get private key
    const privateKey = privateKeyFromSeed(seed)
    
    return privateKey
}

getPrivateKey().then(console.log)
```

### Хеш открытого ключа

После получения приватного ключа вам необходимо зарегистрировать хэш открытого ключа в ZKSwap, чтобы он мог верифицировать отправленные вами транзакции.

```csharp
import { utils } from 'ethers'
import { private_key_to_pubkey_hash } from 'zksync-crypto'

const pubKeyHash = `sync:${utils.hexlify(private_key_to_pubkey_hash(privateKey)).substr(2)}`
```

### Подпись

Перед отправкой транзакции в ZKSwap вам необходимо подписать данные транзакции.

```csharp
import { utils } from 'ethers'
import { sign_musig } from 'zksync-crypto'

function signMessage(privateKey, msgBytes) {
    const signaturePacked = sign_musig(privateKey, msgBytes)
    
    const pubKey = utils.hexlify(signaturePacked.slice(0, 32)).substr(2)
    const signature = utils.hexlify(signaturePacked.slice(32)).substr(2)
    
    return {
        pubKey,
        signature
    }
}

const msgBytes = utils.concat([type, accountId, ...etc])
const signature = signMessage(privateKey, msgBytes)

```

### **Замена открытого ключа**

После того, как учетная запись была «зарегистрирована» в ZKSwap (посредством перевода или депозита), вы можете изменить pubKeyHash учетной записи, чтобы совершать любую транзакцию на Уровне 2. Это особая транзакция, которую не нужно подписывать приватным ключом Уровня 2.

### **Обмен**

#### **Комиссия**

Для примера обменяем токен А на токен В. Есть два способа:

1. Если А – это токен комиссии, то ее размер рассчитывается как `amountIn * 5 / 9995`
2. Если А не выступает в роли токена комиссии, а для комиссии применяется токен В, то ее размер `amountOut * 5 /10000`. Это не `amountOutMin`. `amountOut` равен `amountOutMin` и тогда проскальзывание равно 0.
