A smart contract-based faucet for distributing CELO and cCOP testnet tokens on Celo Sepolia. Uses a trustless, on-chain architecture with a multiplier system that rewards community engagement. Features include reCAPTCHA, optional GitHub and Twitter verification, and a 24-hour cooldown. Built with Next.js, TypeScript, and Solidity, deployed via smart contract for transparency and security.

To accelerate Celo Colombia ecosystem growth by providing a secure, transparent, and community-driven testnet token distribution system. The faucet lowers barriers for developers, incentivizes community engagement through verification multipliers, and demonstrates best practices for decentralized infrastructure. By combining security, transparency, and gamification, we aim to onboard more developers to Celo while building a sustainable, trustless token distribution model.

Developers need testnet tokens to build on Celo, but existing faucets often have:

• Security risks from private keys stored on servers
• Lack of transparency and auditability
• Bot abuse and token drain
• Limited verification mechanisms
• Centralized control and single points of failure
• No incentives for community engagement

A decentralized faucet using a smart contract that:

• Removes private key storage on servers
• Provides full on-chain transparency and auditability
• Implements reCAPTCHA, GitHub OAuth, and Twitter verification to reduce abuse
• Uses a multiplier system (5x GitHub, 5x Twitter, up to 25x combined) to encourage participation
• Enforces 24-hour cooldowns and on-chain rate limiting
• Includes security features (ReentrancyGuard, signature verification, Ownable)
• Enables direct user-to-contract interaction without backend trust
