- Added title: Bitcoin-Stacks Bridge - Included summary detailing the purpose of the contract - Added a comprehensive description outlining key features such as multi-validator consensus, emergency withdrawal mechanism, deposit validation, balance tracking, error handling, and pausable functionality
- Defined constants for contract deployer, deposit limits, required confirmations, minimum validators, and emergency timelock - Added data variables for bridge status, total bridged amount, last processed height, last emergency withdrawal height, and total validators
- Defined `deposits` map to store deposit details including amount, recipient, processed status, confirmations, timestamp, and BTC sender - Added `validators` map to track active validators and their addition time - Created `validator-signatures` map to store signatures and timestamps for each transaction hash and validator - Included `bridge-balances` map to manage balances for each principal
…idator management - Implemented `initialize-bridge` function to set initial bridge state - Added `pause-bridge` function to allow pausing of the bridge by the deployer - Created `add-validator` function to enable the addition of new validators by the deployer
- Implemented `remove-validator` function to deactivate validators by the deployer - Added `initiate-deposit` function to handle deposit initiation with validation checks and deposit recording
- Implemented `confirm-deposit` function to validate and confirm deposits with signature verification and balance updates - Added `withdraw` function to handle withdrawals, ensuring sufficient balance and updating bridge balances
- Implemented `emergency-withdraw` function to allow the deployer to withdraw funds in emergency situations with timelock and balance checks
…osit amount validation - Implemented `get-validator-status` to check if a validator is active - Added `get-bridge-balance` to retrieve the bridge balance of a user - Created `validate-deposit-amount` to ensure deposit amounts are within defined limits
- Refactored validator management functions to improve readability and maintainability - Added functions to validate transactions, ensuring proper authorization and error handling
…cy withdrawal functions - Enhanced `initiate-deposit` function with transaction hash validation - Improved `emergency-withdraw` function with recipient validation
…er guide documentation - Included contributing guidelines to assist new contributors - Added a detailed security policy for reporting vulnerabilities - Implemented a code of conduct to ensure a respectful and inclusive community - Provided a user guide to help users understand and use the bridge contract
