zkSync lite and era

0: 开发环境

web3==6.0.0 python-okx==0.1.9 (用于okx提币)

zksync lite: https://github.com/zksync-sdk/zksync-python.git 只能从源码安装，最好是改一下源码，省的lite和era需要不同的虚拟环境 把源码里的waitForTransactionReceipt=> wait_for_transaction_receipt toChecksumAddress=> to_checksum_address python3 setup.py install

并需要下载crypto library: 文档： https://docs.zksync.io/api/sdk/python/tutorial/ 下载地址 https://github.com/zksync-sdk/zksync-crypto-c/releases

zksync era: pip3 install zksync2

1: 创建eth账号

• 可以随机生成 私钥-地址 对

import secrets
from eth_account import Account
from eth_account.signers.local import LocalAccount
def generate_random_account()-> LocalAccount:
  # or simply return Account.create(), 随机性可能不行
  return Account.from_key(f'0x{secrets.token_hex(32)}')

• 可以先生成 助记词，然后通过助记词生成 私钥-地址 对 (优点：可以只记录助记词就行了)

生成助记词

# generate mnemonic code
from eth_account import Account
Account.enable_unaudited_hdwallet_features()

def gen_mnemonic_code() -> str:
    _, mnemonic = Account.create_with_mnemonic()
    return mnemonic

测试:
gen_mnemonic_code()
=> 'length pact reason inside limb soon main agree broken sentence inquiry narrow'

助记词 + 数字(N)，就回返回该助记词的第N对私钥+地址

from web3 import Web3
from eth_account.signers.local import LocalAccount
from eth_account.hdaccount import ETHEREUM_DEFAULT_PATH

# infura可免费注册，后面也会用到
rpc_url = 'https://mainnet.infura.io/v3/<your-infura-key>'
w3 = Web3(Web3.HTTPProvider(rpc_url))
w3.eth.account.enable_unaudited_hdwallet_features()

def from_mnemonic(mnemonic: str, idx: int = 0) -> LocalAccount:
    account: LocalAccount = w3.eth.account.from_mnemonic(
        mnemonic,
        account_path=f'{ETHEREUM_DEFAULT_PATH}/{idx}'
    )
    return account

测试：
from_mnemonic('length pact reason inside limb soon main agree broken sentence inquiry narrow', 0)
from_mnemonic('length pact reason inside limb soon main agree broken sentence inquiry narrow', 1)
from_mnemonic('length pact reason inside limb soon main agree broken sentence inquiry narrow', 2)

可以从一个非常大的数字开始，这样子就算别人知道了助记词，它也不一定能找得到你的币

2: 从交易网站 将eth提到 zkSync Lite 和 zkSync Era 上

现在okx已经支持直接提到 这两条链了，所以不需要走 跨链了 （跨链： 如 把eth从 以太坊主网，发送到 zkSync Lite上来，或者从Optimism=> zkSync Era,等） 跨链过可能会多给点积分，然后多点空投，但跨链成本相对较高（4，5刀起步）,看个人抉择

官方的跨链桥, ethereum => zkSync lite (https://lite.zksync.io/transaction/deposit) ethereum => zkSync era (https://portal.zksync.io/bridge)

                                  |通过orbiter/multichain等跨链
                                  |
                                  |
                                  V
                           zkSync era/lite

怎样都行，反正最省的肯定是直接提到zksync lite和era上

# distribute eth from okx
from okx import Funding
api_key = "<YOUR-API-KEY>"
secret_key = "<YOUR-SECRET-KEY>"
passphrase = "<YOUR-PASSPHRASE>"
flag = '0'

fundingAPI = Funding.FundingAPI(api_key, secret_key, passphrase, False, flag)

# withdraw eth in ether
withdraw_amount = "1"

# 下面的 0.0002，0.0003, 0.001456可能会变，需要去okx查,或者调 fundingAPI.get_currencies() 获取

# withdraw to zkSync lite
res = fundingAPI.withdrawal("ETH", withdraw_amount, "4", address, "0.0002", "ETH-zkSync Era")

# withdraw to zkSync era
res = fundingAPI.withdrawal("ETH", withdraw_amount, "4", address, "0.0003", "ETH-zkSync Lite")

# withdraw to ethereum mainnet
res = fundingAPI.withdrawal("ETH", withdraw_amount, "4", address, "0.001456")

3: 做链上交互(得改代码)

env=lite PYTHONPATH=. /python layer2/zksync/cron/go_through_lite.py

env=era PYTHONPATH=. /python layer2/zksync/cron/go_through_era.py
