Hi! I’d like to work on this issue.

I have experience building AMM logic and well-tested smart contracts. I’ll implement querying of current YES/NO liquidity, compute the k constant and implied odds, and include solid unit tests to meet the acceptance criteria.

I can deliver a clean, reliable solution and get started immediately. Thank you!

Hello Team,

I’d like to apply for the [Contract] Implement get_market_liquidity query task in Netwalls / BOXMEOUT_STELLA. I have experience working with AMM-based liquidity models, on-chain queries, and Rust smart contracts, and I’m confident I can implement this feature accurately and safely.

For this task, my approach would include:

Querying the AMM pool to retrieve current YES and NO token liquidity

Computing the constant product (k) based on pool reserves

Deriving implied odds from the reserve ratios in a clear and deterministic way

Returning a well-structured response suitable for frontend consumption

Adding unit tests to validate:

Correct liquidity values

Accurate k calculation

Correct implied odds under different reserve scenarios

From a technical standpoint, I’m comfortable working in market.rs, following existing contract patterns, and ensuring all arithmetic is safe and overflow-checked. I pay particular attention to numerical correctness and edge cases, especially in prediction-market and AMM-driven logic where precision is critical.

Given the P1 priority, I’m ready to deliver this feature promptly while maintaining high code quality and test coverage.

Thank you for considering my application.

Best regards,
Mark Odiba
Smart Contract Developer (Rust / AMM Logic)
