[Contract] Quadratic Funding Matching Pool

[Contract] Quadratic Funding Matching Pool

🚀 Feature Overview

Implement a Gitcoin-style quadratic funding contract where community donations are matched by a central pool, mathematically optimizing for the number of unique contributors.

This is a complex, MVP-critical feature designed to elevate the smart contract architecture and expand the educational modules of the Web3 Student Lab platform.

🛠️ Implementation Requirements

• Implement the quadratic matching formula (square root of contributions).\n- Build Sybil resistance checks or whitelist integrations.\n- Ensure precision math for fair distribution of the matching pool.

🔧 Technical Specifications

• Language/Environment: Rust / Soroban (or Solidity if specifically bridging).
• Adherence to strict architectural boundaries and gas optimization.
• High test coverage requirements (>90% unit testing in Rust).
• Prevent common vectors: Reentrancy, Integer Overflow/Underflow, and Oracle Manipulation.

✅ Acceptance Criteria

• Contract implemented according to requirements.
• Comprehensive unit and integration tests passing.
• Security review completed (no critical vulnerabilities).
• Comprehensive documentation written using NatSpec/Rustdoc.

🎓 Difficulty Level

Advanced - Requires deep understanding of Web3 security, cryptography, and smart contract design patterns.

Hi maintainer.

Can you please assign this issue to me?

I have deep expertise in Rust and
Soroban smart contract development, along with a strong background in precision
math and advanced Web3 security. I am fully prepared to implement the quadratic
funding formula with robust Sybil resistance, strict gas optimization, and
over 90% test coverage to guarantee a vulnerability-free contract.
