You should do a basic implementation of an ERC20 token with the specified requirements using Solidity and the OpenZeppelin library.
To set up your development environment:
- Install Node.js: Download and install Node.js from https://nodejs.org/.
- Install Hardhat: Open a terminal and run the following command to install Hardhat globally:
npm install -g hardhat
- Create a new Hardhat project:
mkdir my-token && cd my-token npx hardhat
- Install OpenZeppelin Contracts:
npm install @openzeppelin/contracts
Now, you can create your custom token contract:
Create a new file named MyToken.sol in the contracts folder:
// contracts/MyToken.sol
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
contract MyToken is ERC20, Ownable {
address public marketingWallet;
address public devWallet;
constructor(address _marketingWallet, address _devWallet) ERC20("My Token", "MYT") {
require(_marketingWallet != address(0) && _devWallet != address(0), "Invalid wallet addresses");
marketingWallet = _marketingWallet;
devWallet = _devWallet;
uint256 totalSupply = 15 * 10**9 * 10**18; // 15 billion tokens with 18 decimals
uint256 devTokens = (totalSupply * 5) / 100; // 5% for dev wallet
uint256 marketingTokens = (totalSupply * 5) / 100; // 5% for marketing wallet
_mint(devWallet, devTokens);
_mint(marketingWallet, marketingTokens);
_mint(msg.sender, totalSupply - devTokens - marketingTokens);
}
function _transfer(address sender, address recipient, uint256 amount) internal override {
// Implement your custom fees and limits logic here
super._transfer(sender, recipient, amount);
}
}
This is a basic implementation of your token. You'll need to add the custom fees and limits logic in the _transfer function. You can also add the auto liquidity generation and trading pair features as needed.
npx hardhat compile
- Deploy the contract:
Create a new file named deploy.js in the scripts folder:
// scripts/deploy.js
async function main() {
const [deployer] = await ethers.getSigners();
console.log("Deploying contracts with the account:", deployer.address);
const MyToken = await ethers.getContractFactory("MyToken");
const myToken = await MyToken.deploy("0xMarketingWalletAddress", "0xDevWalletAddress");
console.log("MyToken address:", myToken.address);
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});
Replace 0xMarketingWalletAddress and 0xDevWalletAddress with the actual wallet addresses.
Add a local network to your hardhat.config.js:
module.exports = {
networks: {
hardhat: {
chainId: 1337,
},
},
solidity: "0.8.4",
};
Run a local Hardhat node:
npx hardhat node
Deploy the contract to the local network:
npx hardhat run --network hardhat scripts/deploy.js
This will give you a basic implementation of your token. You can further customize it by adding the required fees, limits, and other features as needed.
