ERC-20 Token with Faucet & Dashboard
Launch your own test token with a cooldown faucet and transfer UI
1-2 weeks build
Overview
A first smart-contract project: write an ERC-20 token on OpenZeppelin, deploy it to Sepolia or local Hardhat, and add a faucet contract that hands out a fixed amount per wallet with a cooldown between claims. A React dashboard connects MetaMask, shows balances and supply, and sends transfers. The token is a test token with no monetary value.
What makes it stand up
- 01ERC-20 token built on audited OpenZeppelin code
- 02Faucet with per-wallet cooldown enforced on-chain
- 03Balance, supply and recent-transfer dashboard
- 04Hardhat unit tests for token and faucet rules
- 05Deploy script for Sepolia or a local chain
