Token Minter

Overview

This skill enables users to create custom ERC20 tokens by collecting parameters, generating Solidity code, setting up a Foundry project, building the contract, and deploying to a target EVM network.

Workflow

Step 1: Collect Information

Collect the following parameters from the user:

• Token name (e.g., "MyToken")
• Token symbol (e.g., "MTK")
• Decimals (default: 18)
• Initial supply (default: 1000000)
• Target network (default: sepolia)

Step 2: Generate ERC20 Contract

Use the provided script to generate the ERC20 contract code based on user parameters.

• Run python scripts/generate_contract.py <name> <symbol> <decimals> <initial_supply> to generate the contract
• The generated contract uses OpenZeppelin ERC20 standard

Step 3: Initialize Forge Project

• Create a temporary directory under ./tmp/
• Initialize a new Foundry project: forge init
• Place the generated contract in src/Contract.sol

Step 4: Build Contract

• Install dependencies: forge install OpenZeppelin/openzeppelin-contracts
• Build the contract: forge build

Step 5: Deploy to Network

• Ensure a local cast wallet is created (prerequisite)
• Get RPC URL for target network from https://chainlist.org/rpcs.json
  • Find the network entry and use a reliable HTTPS RPC URL
  • For Sepolia: typically "https://ethereum-sepolia.publicnode.com" or similar
• Deploy using: forge create --rpc-url <network_rpc> --account <account_name> src/Contract.sol:MyToken --constructor-args <initial_supply> --broadcast
• Verify deployment on the target network

Prerequisites

• Foundry installed (forge, cast commands available)
• Local cast wallet created with cast wallet new
• Sufficient funds on the deployment account for gas fees
