# 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ru.wiki.zks.org/vzaimodeistvie-s-zkswap/sozdanie-tranzakcii.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
