Создание транзакции

В данной статье мы будем использоваться этот кошелек для примера:

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

[
  {
    "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:

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).

Пример кода:

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, чтобы получить приватный ключ.

Access ZKSwap account.

Only sign this message for a trusted client!

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

Вот полный пример получения приватного ключа с помощью zksync-crypto в JavaScript.

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.

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.

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:

Если А – это токен комиссии, то ее размер рассчитывается как amountIn * 5 / 9995
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.
