- Introduce a smart contract for managing and aggregating Bitcoin yield across multiple protocols. - Define error constants for various failure scenarios. - Implement protocol management, user deposit tracking, yield calculation, and risk management functionalities. - Ensure proper authorization and enforce protocol constraints to maintain system integrity.
- Define `supported-protocols` map to store protocol details including name, base APY, max allocation percentage, and active status. - Introduce `total-protocols` data variable to keep track of the number of protocols. - Define `user-deposits` map to store user deposits with amount and deposit time. - Define `protocol-total-deposits` map to track the total deposits for each protocol.
- Define `CONTRACT-OWNER` constant to store the contract owner's principal. - Introduce constants `MAX-PROTOCOLS`, `MAX-ALLOCATION-PERCENTAGE`, and `BASE-DENOMINATION` for protocol limits and calculations. - Implement `is-contract-owner` private function to check if the sender is the contract owner.
- Add `add-protocol` public function to allow the contract owner to add new yield protocols. - Ensure only the contract owner can add protocols using the `is-contract-owner` check. - Enforce a limit on the number of protocols using `MAX-PROTOCOLS`. - Store protocol details in the `supported-protocols` map and update the `total-protocols` counter.
- Add `deposit` public function to allow users to deposit Bitcoin into specified yield protocols. - Validate the protocol's existence and active status using `supported-protocols` map. - Ensure the deposit does not exceed the protocol's maximum allocation percentage. - Update user deposits in the `user-deposits` map and protocol total deposits in the `protocol-total-deposits` map.
- Implement `calculate-yield` read-only function to compute the yield for a user's deposit in a specified protocol. - Calculate the yield based on the protocol's base APY and the number of blocks since the deposit. - Add `withdraw` public function to allow users to withdraw their deposits along with the accrued yield. - Validate the withdrawal amount and update the user and protocol deposits accordingly.
- Implement `deactivate-protocol` public function to allow the contract owner to deactivate a protocol. - Ensure only the contract owner can deactivate protocols using the `is-contract-owner` check. - Update the protocol's active status and decrement the `total-protocols` counter. - Add `initialize-protocols` public function to initialize default protocols with error checking. - Automatically initialize protocols upon contract deployment using `try!`.
…nagement - Introduce constants `MAX-PROTOCOL-NAME-LENGTH`, `MAX-BASE-APY`, and `MAX-DEPOSIT-AMOUNT` for input validation. - Implement private functions `is-valid-protocol-id`, `is-valid-protocol-name`, `is-valid-base-apy`, `is-valid-allocation-percentage`, and `is-valid-deposit-amount` to validate inputs. - Enhance input validation in `add-protocol`, `deposit`, and `deactivate-protocol` functions to ensure data integrity.
- Provide an overview of the Bitcoin Yield Aggregator smart contract. - List key features including multi-protocol yield aggregation, secure mechanisms, and risk management. - Outline prerequisites for using the contract. - Include installation steps for setting up the development environment. - Detail contract capabilities such as adding protocols, depositing funds, calculating yield, and withdrawing funds. - Highlight security measures including owner-only management and input validation. - List supported protocols. - Provide usage examples for depositing, calculating yield, and withdrawing funds. - Discuss risks and considerations associated with the contract. - Include sections for contributing, license, and support.
- Welcome contributors and provide an overview of the contribution process. - Include a code of conduct to ensure a friendly and safe environment. - Outline steps for reporting bugs and submitting feature requests. - Detail the pull request process, including forking the repository, creating feature branches, and writing clear commit messages. - Provide development setup instructions and smart contract development guidelines. - Describe the code review process and emphasize respectful and constructive feedback. - Encourage communication through community discussions and GitHub issues. - Acknowledge contributors in the project's documentation.
- Outline supported versions and their support status. - Provide guidelines for reporting vulnerabilities, including contact information and required details. - List security best practices such as regular code audits, comprehensive testing, and input validation. - Highlight smart contract security considerations like preventing integer overflow/underflow and implementing access controls. - Describe the response process for handling reported vulnerabilities, from acknowledgment to responsible disclosure. - Mention the reward program for critical vulnerabilities. - Include a disclaimer about the inherent risks in any system.
- Commit to providing a harassment-free, inclusive environment for everyone. - Define positive behaviors such as respect, constructive feedback, collaboration, and empathy. - List unacceptable behaviors including harassment, discrimination, offensive comments, and unprofessional conduct. - Outline responsibilities of project maintainers to clarify standards, handle complaints, and enforce guidelines. - Provide instructions for reporting issues and ensure all complaints will be reviewed and investigated. - Detail enforcement actions for violations, including verbal warnings, temporary bans, and permanent exclusions. - Attribute the Code of Conduct to the Contributor Covenant, version 2.1.
