Hi @Mkalbani,

I’m interested in implementing the Liquidity Mining and Yield Farming Contract. I can develop a secure staking architecture on Soroban that supports both fungible tokens and NFTs with automated reward logic.

My Plan:

Pool Design: Creating a modular staking structure that handles balance tracking and lock-up enforcement.

Yield Engine: Implementing APY-based calculations with reward distribution and early withdrawal penalty logic.

NFT & Advanced Features: Adding support for NFT staking, pool multipliers, and an auto-compounding mechanism.

Experience:

DeFi Logic: Proficient in designing staking and yield-bearing asset contracts on Soroban.

Rust/Soroban: Experienced with soroban-sdk and managing state for high-frequency reward updates.

Security: Skilled in implementing reentrancy guards and validating complex math for financial protocols.

If this looks good, please assign the issue to me!

Thanks!
