- Implemented SIP-010 token standard for token interactions. - Added constants for contract name and various error codes. - Included error handling for authorization, invalid amounts, insufficient balance, strategy management, and more.
- Defined data variables for contract owner, emergency shutdown, TVL, fees, max strategies, and token contract. - Added data maps for strategies, user deposits, and strategy allocations.
- Defined a data variable for strategy type with relevant fields. - Implemented read-only functions to get strategy list, strategy info, user info, total TVL, token contract, best strategy calculation, and active strategies.
- Defined the `sip-010-token` trait with required functions for token transfer, total supply, balance, name, symbol, decimals, and token URI.
…tract - Implemented `convert-to-filtered-strategy` to filter strategy details. - Added `is-strategy-active` to check if a strategy is active based on its APY. - Created `calculate-highest-apy` to determine the strategy with the highest APY.
- Implemented `deposit` function to handle token deposits and share calculations. - Added `withdraw` function to manage token withdrawals and share deductions. - Included SIP-010 trait implementation for token transfer, name, symbol, decimals, balance, total supply, and token URI.
- Implemented `add-strategy` to add new strategies with specified parameters. - Added `update-strategy-apy` to update the APY of a strategy. - Created `toggle-emergency-shutdown` to enable or disable emergency shutdown. - Included `set-token-contract` to set the token contract address.
- Implemented `is-contract-owner` to check if the sender is the contract owner. - Added `calculate-shares` to calculate the number of shares for a given amount. - Created `calculate-withdrawal-amount` to determine the withdrawal amount based on shares. - Included `allocate-to-best-strategy` to allocate funds to the best strategy. - Added `reallocate-funds` to reallocate funds to a specific strategy.
- Implemented `unwrap-strategy` to convert strategy ID to full strategy info. - Added `verify-token` to check if the token is allowed. - Created `validate-strategy-params` to validate strategy parameters. - Included `validate-strategy-id` to validate the strategy ID.
- Added contributing guidelines to guide contributors on how to contribute to the project. - Included a license file with the MIT License. - Added technical documentation detailing the contract's key components, functions, and usage.
