This is a public mint tool for https://etherscan.io/address/0x984f7b398d577c0adde08293a53ae9d3b6b7a5c5

All pubic mint tools should be cutomized. However, the baseline are the same. You can use it as a start point.

There are several places you need to change code based on contrat and mint settings. So you need to understand the smart contract first.

Pre-requirement

1 Nodejs.v14 is recommended. 2 Alchemy wss api is required. The api is free. You can create account by yourself.

Configuration

In config.js. we need to change thing before use.

// 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"

In public.js, there are two place need to be customized:

1. Change mint function name

//----------------------------------------------------------------- //--------------- Change this function every time------------------

let extraData = await contract.methods.mintSAC(config.number);

//----------------------------------------------------------------- //-----------------------------------------------------------------

2. Change the signal that you want to monitor

//----------------------------------------------------------------- //--------------- Change this function every time------------------

if((decodedData.name == 'flipPublicSaleState')){

//----------------------------------------------------------------- //-----------------------------------------------------------------

In abi.json, you need to copy the smart contract abi and paste in abi.json.
