- Implement `set-fee-percentage` to allow the contract owner to update the fee percentage, ensuring it remains within valid bounds (0-100%). - Implement `set-fee-address` to allow the contract owner to update the fee recipient address. - Add error handling for unauthorized access and invalid inputs. - Enhance flexibility in fee management for the BitSwap DEX protocol.
- Add `create-pool` function to enable the creation of new liquidity pools with unique token pairs. - Add `add-liquidity` function to allow users to provide liquidity to existing pools, minting proportional shares. - Ensure error handling for invalid inputs, duplicate pools, and slippage protection. - Update pool balances and provider shares upon successful liquidity addition. - Enhance core functionality of the BitSwap DEX for liquidity management.
- Add `remove-liquidity` function to allow users to withdraw liquidity from a pool. - Calculate token amounts to be returned based on the user's share of the pool. - Update pool balances and provider shares after liquidity removal. - Ensure error handling for insufficient shares, slippage protection, and expired deadlines. - Transfer tokens back to the provider securely after successful withdrawal. - Enhance the BitSwap DEX with robust liquidity management capabilities.
- Add `swap-exact-tokens-for-tokens` function to enable token swaps using the constant product AMM formula. - Calculate output amount (`amount-out`) based on input amount (`amount-in`) and pool reserves. - Deduct fees from the input amount and transfer them to the designated fee address. - Update pool balances, price oracle data, and protocol metrics after each swap. - Ensure error handling for insufficient liquidity, slippage protection, and expired deadlines. - Enhance trading capabilities of the BitSwap DEX with secure and efficient token swaps.
- Implement `get-reserves` to retrieve the reserves and total shares of a specific liquidity pool. - Add `get-provider-shares` to fetch the LP shares owned by a specific provider in a pool. - Implement `quote-exact-tokens-for-tokens` to calculate the output amount of token B for a given input amount of token A, considering pool reserves and fees. - Ensure error handling for non-existent pools and zero liquidity scenarios. - Enhance the BitSwap DEX with utility functions for better user and protocol interaction.
- Implement `get-price` to calculate the price of token A in terms of token B, scaled for precision. - Add `get-pool-by-id` to retrieve detailed information about a specific liquidity pool by its ID. - Add `get-protocol-metrics` to provide an overview of key protocol metrics, including total volume, fees collected, and unique providers. - Include a private helper function `abs-diff` to calculate the absolute difference between two unsigned integers. - Enhance the BitSwap DEX with comprehensive utility functions for better analytics and user interaction.
- Document key features, including Bitcoin-secured liquidity pools, advanced AMM design, and Stacks L2 optimizations. - Provide detailed descriptions of core components such as liquidity pools, AMM, fee mechanisms, and oracle systems. - Include a table of contract functions categorized into pool management, trading operations, administrative, and view functions. - Add usage examples for creating pools, adding liquidity, and executing swaps. - Outline the security model with audited features and error codes for better transparency and reliability. - Enhance developer and user understanding of the BitSwap DEX protocol.

Purpose
This PR introduces the foundational components of the BitSwap decentralized exchange, enabling Bitcoin-secured liquidity provisioning, trustless trading, and enterprise-grade DeFi operations on Stacks L2. The changes establish a robust framework for liquidity pool management, fee configuration, and MEV-resistant swaps while ensuring compliance with Bitcoin's security model.
