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
