🫘 Contributions to Beanstalk’s Basin Protocol

As a contributor to Basin, I worked across the Pump subsystem, gas-efficiency pathways, and modernization of the Solidity codebase. My work focused on improving performance, safety, and clarity of the AMM’s core components.

🔑 Key Contributions

Optimized Pump Logic (GeoEma, CumSma, and related math)

  • Improved and refactored core Pump contracts for better readability and mathematical correctness.
  • Strengthened clarity around Basin’s time-weighted pricing mechanisms.

Low-Level Yul Optimizations

  • Applied selective Yul blocks to reduce gas in tight loops and high-frequency execution paths.
  • Minimized redundant memory operations and unnecessary stack juggling to improve runtime efficiency.

Gas Efficiency Improvements Across the Codebase

  • Authored multiple PRs targeting micro-optimizations.
  • Simplified arithmetic, reduced branching, and streamlined logic to lower execution costs.

Modernized Solidity Usage

  • Removed deprecated patterns such as ABIEncoderV2.
  • Standardized compiler pragmas and aligned contracts with modern Solidity best practices.

Feature Refinement & Implementation

  • Worked on iterative improvements to Pump functionality.
  • Contributed cleanup and correctness fixes that tightened invariant behavior across the AMM’s pricing logic.

Fuzzing & Invariant Testing

  • Conducted property-based fuzzing and invariant checks.
  • Validated Pump behavior under adversarial and edge-case inputs to ensure stability and safety.

📈 Impact

These contributions improved Basin’s reliability, reduced long-term gas costs, and strengthened both the mathematical and engineering foundation of the protocol. The result is a more efficient, modern, and test-hardened AMM framework within the broader Beanstalk ecosystem.
