Install OpenZeppelin contracts for secure, audited ERC-20 implementation:

Terminal
# Install OpenZeppelin contracts library
forge install OpenZeppelin/openzeppelin-contracts

​
Smart Contract Development

Create your token contract using OpenZeppelin’s ERC-20 implementation:

src/MyToken.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.19;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

/**
 * @title MyToken
 * @dev ERC-20 token with minting capabilities and supply cap
 */
contract MyToken is ERC20, Ownable {
    // Maximum number of tokens that can ever exist
    uint256 public constant MAX_SUPPLY = 1_000_000_000 * 10**18; // 1 billion tokens
    
    constructor(
        string memory name,
        string memory symbol,
        uint256 initialSupply,
        address initialOwner
    ) ERC20(name, symbol) Ownable(initialOwner) {
        require(initialSupply <= MAX_SUPPLY, "Initial supply exceeds max supply");
        // Mint initial supply to the contract deployer
        _mint(initialOwner, initialSupply);
    }
    
    /**
     * @dev Mint new tokens (only contract owner can call this)
     * @param to Address to mint tokens to
     * @param amount Amount of tokens to mint
     */
    function mint(address to, uint256 amount) public onlyOwner {
        require(totalSupply() + amount <= MAX_SUPPLY, "Minting would exceed max supply");
        _mint(to, amount);
    }
    
    /**
     * @dev Burn tokens from caller's balance
     * @param amount Amount of tokens to burn
     */
    function burn(uint256 amount) public {
        _burn(msg.sender, amount);
    }
}

​
Deployment Script

Create a deployment script following Foundry best practices:

script/DeployToken.s.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.19;

import {Script, console} from "forge-std/Script.sol";
import {MyToken} from "../src/MyToken.sol";

contract DeployToken is Script {
    function run() external {
        // Load deployer's private key from environment variables
        uint256 deployerPrivateKey = vm.envUint("PRIVATE_KEY");
        address deployerAddress = vm.addr(deployerPrivateKey);
        
        // Token configuration parameters
        string memory name = "My Token";
        string memory symbol = "MTK";
        uint256 initialSupply = 100_000_000 * 10**18; // 100 million tokens
        
        // Start broadcasting transactions
        vm.startBroadcast(deployerPrivateKey);
        
        // Deploy the token contract
        MyToken token = new MyToken(
            name,
            symbol,
            initialSupply,
            deployerAddress
        );
        
        // Stop broadcasting transactions
        vm.stopBroadcast();
        
        // Log deployment information
        console.log("Token deployed to:", address(token));
        console.log("Token name:", token.name());
        console.log("Token symbol:", token.symbol());
        console.log("Initial supply:", token.totalSupply());
        console.log("Deployer balance:", token.balanceOf(deployerAddress));
    }
}

​
Environment Configuration

Create a .env file with your configuration:

.env
PRIVATE_KEY=your_private_key_here
BASE_SEPOLIA_RPC_URL=https://sepolia.base.org
BASE_MAINNET_RPC_URL=https://mainnet.base.org
BASESCAN_API_KEY=your_basescan_api_key_here

Update foundry.toml for Base network configuration:

foundry.toml
[profile.default]
src = "src"
out = "out"
libs = ["lib"]
remappings = ["@openzeppelin/=lib/openzeppelin-contracts/"]

[rpc_endpoints]
base_sepolia = "${BASE_SEPOLIA_RPC_URL}"
base_mainnet = "${BASE_MAINNET_RPC_URL}"

[etherscan]
base_sepolia = { key = "${BASESCAN_API_KEY}", url = "https://api-sepolia.basescan.org/api" }
base = { key = "${BASESCAN_API_KEY}", url = "https://api.basescan.org/api" }

​
Testing

Create comprehensive tests for your token:

test/MyToken.t.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.19;

import {Test, console} from "forge-std/Test.sol";
import {MyToken} from "../src/MyToken.sol";

contract MyTokenTest is Test {
    MyToken public token;
    address public owner = address(0x1);
    address public user = address(0x2);
    
    uint256 constant INITIAL_SUPPLY = 100_000_000 * 10**18;
    
    function setUp() public {
        // Deploy token contract before each test
        vm.prank(owner);
        token = new MyToken("Test Token", "TEST", INITIAL_SUPPLY, owner);
    }
    
    function testInitialState() public {
        // Verify token was deployed with correct parameters
        assertEq(token.name(), "Test Token");
        assertEq(token.symbol(), "TEST");
        assertEq(token.totalSupply(), INITIAL_SUPPLY);
        assertEq(token.balanceOf(owner), INITIAL_SUPPLY);
    }
    
    function testMinting() public {
        uint256 mintAmount = 1000 * 10**18;
        
        // Only owner should be able to mint
        vm.prank(owner);
        token.mint(user, mintAmount);
        
        assertEq(token.balanceOf(user), mintAmount);
        assertEq(token.totalSupply(), INITIAL_SUPPLY + mintAmount);
    }
    
    function testBurning() public {
        uint256 burnAmount = 1000 * 10**18;
        
        // Owner burns their own tokens
        vm.prank(owner);
        token.burn(burnAmount);
        
        assertEq(token.balanceOf(owner), INITIAL_SUPPLY - burnAmount);
        assertEq(token.totalSupply(), INITIAL_SUPPLY - burnAmount);
    }
    
    function testFailMintExceedsMaxSupply() public {
        // This test should fail when trying to mint more than max supply
        uint256 excessiveAmount = token.MAX_SUPPLY() + 1;
        
        vm.prank(owner);
        token.mint(user, excessiveAmount);
    }
    
    function testFailUnauthorizedMinting() public {
        // This test should fail when non-owner tries to mint
        vm.prank(user);
        token.mint(user, 1000 * 10**18);
    }
}

Run your tests:

Terminal
# Run all tests with verbose output
forge test -vv

​
Deployment and Verification

Deploy to Base Sepolia testnet:

Terminal
# Load environment variables
source .env

# Deploy to Base Sepolia with automatic verification
forge script script/DeployToken.s.sol:DeployToken \
    --rpc-url base_sepolia \
    --broadcast \
    --verify

The --verify flag automatically verifies your contract on BaseScan, making it easier for users to interact with your token.

To deploy to Base Mainnet, simply change base_sepolia to base_mainnet in your deployment command. Ensure you have sufficient ETH on Base Mainnet for deployment and gas fees.

​
Post-Launch Considerations

Once your token is deployed, here are the key next steps to consider:

​
Token Distribution and Economics

Carefully consider your token’s supply and distribution settings. Think through how tokens will be distributed to your community, team, and ecosystem participants. Consider factors like vesting schedules, allocation percentages, and long-term incentive alignment.

​
Community and Social Presence

Establish a community and social presence around your token and project. This includes creating documentation, setting up social media accounts, engaging with the Base ecosystem, and building relationships with other projects and developers.

​
Liquidity and Trading

Add liquidity to decentralized exchanges like Uniswap to enable trading. Note that token launchers will typically handle this for you automatically, but for custom deployments, you’ll need to create trading pairs and provide initial liquidity.

​
Continued Development
