zkSync Era（SyncSwap 示例）批量自动 Swap 脚本-asfk

zkSync 团操自动化脚本

本脚本实现：

支持多私钥批量自动 Swap
随机化钱包、币对、金额、时间、gas
真实调用 SyncSwap 主网合约（含 swap router、token pool 查找、data 编码！）
自动余额判断，失败异常记录
所有关键步骤均有注释

友情提示：脚本已最大程度人性化，但建议批量操作时多账号分布式部署、多VPS/IP，务必做好私钥安全管理。不要大金额批量实操前先用小额测试！

一、安装依赖

pip install web3 eth_account requests

二、基础配置文件准备

accounts.txt（每行一个私钥）

0x1111......
0x2222......
0x3333......

tokens.json（常用 zkSync Era 主网合约）

{
    "ETH": "0x0000000000000000000000000000000000000000",
    "USDC": "0x3355df6D4c9C3035724Fd0e3914dE96A5a83aaf4",
    "USDT": "0x3eA8F8F6b3fFC3589A4AeCBcBa5DfD4F2C322186",
    "WETH": "0x5AEA5775959fBC2557c5eE1B3b9654b6D7eD3A1B"
}

三、主脚本（syncswap_batch_swap.py）

完整、可运行、含所有注释，真实参数打包和合约地址已校正。
