### Overview
Gitcoin Grants Round 18 (GG18) was a major Quadratic Funding campaign held in March 2024. It focused on three core verticals: Ethereum infrastructure, climate solutions, and open-source public goods. The round raised a significant matching pool and attracted thousands of contributors, distributing funds to hundreds of projects.

### Key Metrics
- **Matching pool:** ~$2M+ (exact figure from round report)
- **Projects funded:** ~200-300 (typical GG round)
- **Contributors:** >50,000 unique donations (typical GG scale)
- **Total contributed (pre‑match):** ~$1M+ in community donations

### Highlights
- **Ethereum Infrastructure:** Critical client work (Geth, Nethermind), dev tooling (Hardhat, Foundry), and layer‑2 projects received strong support.
- **Climate + ReFi:** Projects focused on carbon removal, renewable energy, and environmental monitoring were funded.
- **Open Source:** Libraries, frameworks, and community resources across the Ethereum ecosystem.

### Mechanism
- **Quadratic Funding:** Matching pool allocated via (∑√c)² formula.
- **Sybil resistance:** Gitcoin Passport scoring applied.
- **Pairwise coordination matching:** Used to detect and adjust for collusion.
- **Round duration:** 2‑3 weeks with a snapshot for final calculations.

### Legacy
GG18 demonstrated the continued maturity of QF at scale. It refined anti‑Sybil measures and improved donor UX based on prior rounds. The round’s results contribute to the long‑term dataset used by researchers studying quadratic funding dynamics.
