description	Generate, build, and deploy custom ERC20 tokens on EVM networks. Use when users want to create and deploy their own ERC20 tokens with custom parameters like name, symbol, decimals, and initial supply. Supports deployment to various networks including Sepolia testnet and requires Foundry (forge/cast) for blockchain interactions.

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
