以这个NFT发售为例 https://etherscan.io/address/0x984f7b398d577c0adde08293a53ae9d3b6b7a5c5
虽然没个NFT的合约不一样，但是抢NFT的基本原理都是一样的，你只需要修改几个配置就可以轻松使用这个工具。
1 Nodejs.v14 以上 2 免费申请一个Alchemy wss api
注意：Alchemy支持ETH和Polygon，其他公链需要用另外的api和调用方法，不懂的朋友通过最底下的电报联系我
// required. wallet privateKey, you can find it in your metamask
privateKey : "<Your private key>",
// required. Your wallet address
fromAddress : "<Your wallet address>".toLocaleLowerCase(),
// reuiqred. Your target contract address
toAddress: "<Your target contract address>".toLocaleLowerCase(),
// required. Find out the contract creator address
creatorAddress: "<The creator wallet address>".toLocaleLowerCase(),
// required. The price of public mint. It should based on the smart contract
price: "0.08",
// required. How many items you wants to buy
maxPriorityFeePerGas : "200",
// required. The collection contract address you want to buy
maxFeePerGas : "300",
// required. The num you want to mint
number: "1",
// required. http provider from alchemy. It must be wss
wssMainnet: "wss://eth-mainnet.alchemyapi.io/v2/<mainnet api key>",
// required. http provider from alchemy. It must be wss
wssRinkeby: "wss://eth-rinkeby.alchemyapi.io/v2/<Rinkeby api key>",
// required. http provider from alchemy. It must be wss
wssGoerli : "wss://eth-goerli.alchemyapi.io/v2/<Goerli api key>",
// optional. debug usage. The value should be "Rinkeby" for rinkeby, "Goerli" for goerli or "" for mainnet
network : "Goerli"
1. 修改Mint的函数名
本案例为：mintSAC
//-----------------------------------------------------------------
//--------------- Change this function every time------------------
let extraData = await contract.methods.mintSAC(config.number);
//-----------------------------------------------------------------
//-----------------------------------------------------------------
2. 更改要监视的信号
本案例为：flipPublicSaleState，当监测到智能合约有这个动作，立即发出交易
//-----------------------------------------------------------------
//--------------- Change this function every time------------------
if((decodedData.name == 'flipPublicSaleState')){
//-----------------------------------------------------------------
//-----------------------------------------------------------------
你需要从智能合约中复制abi，并粘贴替换原有abi.json中的内容。
