faucetbot

A simple Python bot to automatically request testnet USDC or EURC tokens from the Circle Faucet every hour.

Useful for developers testing smart contracts on networks like Uniswap V4, Base, Arbitrum, and others.

🚀 Features

• Requests USDC or EURC tokens from the Circle faucet
• Supports multiple chains (ETH, BASE, UNI, OP, ARB, AVAX, etc.)
• Logs all requests to ~/.faucetbot/{chain}_{token}_log.jsonl
• Automatically rotates logs when they get too large
• Configurable request interval (default: every 1 hour)

🛠 Installation

pip install faucetbot

⚙️ Usage

faucetbot 0xYourWalletAddressHere

Optional Flags

Example

faucetbot 0x1234567890abcdef --token EURC --chain UNI --interval 1800

📂 Logs

Logs are stored by chain and token in your home directory:

~/.faucetbot/uni_usdc_log.jsonl

Each line is a JSON object with timestamp, status, and response.

Logs rotate when they reach ~5MB and are archived as:

~/.faucetbot/uni_usdc_log.jsonl.<timestamp>.bak

⚠️ Rate Limiting

The Circle faucet enforces rate limits per wallet address. If you see "rate_limited" in your logs, wait a few hours before retrying.

The bot will still log the attempt as a failure.
