Automated Liquidity Pool Contract

[Mkalbani]

Location: contracts/liquidity_pool
Language: Rust (Soroban)
Estimated Time: 8 hours
Difficulty: Hard

Description

Build a liquidity pool enabling token swaps with automated pricing using constant product formula (x*y=k).

Tasks

• Design pool structure with two assets
• Implement constant product AMM formula
• Add liquidity provider (LP) token minting
• Create swap functionality
• Implement slippage protection
• Add liquidity addition/removal
• Create fee collection system
• Write comprehensive tests
• Implement price oracle
• Add impermanent loss tracking

Acceptance Criteria

• Swaps execute correctly
• Pricing follows formula
• LP tokens minted/burned correctly
• Slippage limits enforced
• Fees collected and tracked
• All tests pass

Hi, I’m Chukwemeka, a software engineer with strong experience in Rust, Soroban smart contracts, and financial protocol development. I’d like to work on this issue by designing and implementing a secure constant-product AMM that supports liquidity provisioning, token swaps, LP token accounting, fee collection, and slippage protection while maintaining predictable on-chain behavior and efficient storage usage.

My approach is to build the pool around the standard x*y=k invariant, implement precise liquidity minting and burning logic, and ensure swaps correctly enforce slippage limits and fee calculations. I’ll also add comprehensive test coverage for pool initialization, liquidity additions/removals, swap execution, fee accrual, edge cases, and invariant preservation under different market conditions.

Beyond the core AMM functionality, I’ll implement the requested oracle and impermanent-loss tracking features in a way that integrates cleanly with the pool architecture and remains easy to audit and extend. The goal is to deliver a production-ready liquidity pool contract with strong correctness guarantees, clear documentation, and thorough test coverage.
