kukapay 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
