- Implemented trait usage for `ft-trait` and `protocol-trait`. - Defined error codes for various contract operations including authorization, protocol validation, balance checks, amount validation, protocol activity status, slippage, and protocol limit.
- Added `contract-owner` to store the principal of the contract owner. - Added `protocol-count` to keep track of the number of protocols. - Added `min-deposit` to set the minimum deposit amount in smallest units. - Added `max-slippage` to define the maximum allowable slippage (0.5%). - Added `platform-fee` to specify the platform fee (0.1%).
- Defined `protocols` map to store protocol details including address, activity status, TVL, APY, and type.
- Defined `user-deposits` map to store user deposit details including amount, rewards, deposit height, and last claim.
- Defined `protocol-assets` map to store asset details for each protocol including balance, lending rate, borrowing rate, and utilization.
- Implemented `add-protocol` function to add a new protocol to the aggregator. - Includes checks for contract ownership and maximum protocol limit. - Updates the `protocols` map and increments the `protocol-count`.
- Implemented `smart-deposit` function to deposit assets into the best yielding protocol. - Includes checks for minimum deposit amount and protocol activity status. - Transfers tokens to the contract and updates user deposits and protocol TVL.
- Implemented `withdraw` function to allow users to withdraw assets from a protocol. - Includes checks for sufficient balance and protocol activity status. - Calculates fees and rewards, transfers tokens back to the user, and updates user deposits and protocol TVL.
- Implemented `claim-rewards` function to allow users to claim rewards from a protocol. - Includes checks for valid reward amount and protocol activity status. - Updates user rewards and deposit information.
- Implemented `update-protocol-stats` function to update APY and TVL of a protocol. - Includes checks for contract ownership and protocol activity status. - Merges new
- Implemented `get-best-protocol` function to determine the best protocol based on APY and TVL. - Utilizes `fold` and `check-protocol` to compare protocols.
- Implemented `get-user-deposit` function to retrieve the deposit amount of a user in a specific protocol. - Returns the deposit amount or `u0` if no deposit is found.
…ract - Implemented `get-deposit-height` function to retrieve the block height at which a user made a deposit in a specific protocol. - Returns the deposit height or `u0` if no deposit is found.
- Implemented `calculate-rewards` function to compute rewards based on deposit amount and elapsed time. - Considers deposit amount, deposit height, protocol APY, and blocks elapsed. - Returns calculated rewards or `u0` if deposit or blocks elapsed is zero.
…ldCraft contract - Implemented `calculate-fee` function to compute the platform fee based on the given amount. - Implemented `update-protocol-tvl` function to update the total value locked (TVL) of a protocol based on deposit or withdrawal.
…ip in YieldCraft contract - Implemented `is-protocol-active` function to check if a protocol is active. - Implemented `is-contract-owner` function to verify if the sender is the contract owner.
- Implemented `check-protocol` function to compare two protocols and determine the one with the higher APY. - Utilizes `unwrap-panic` to safely retrieve protocol data.
…ntract - Implemented `generate-sequence` function to generate a sequence of numbers from start to end. - Currently returns a list containing only the start value.
- Implemented contract initialization to set initial values for contract owner, protocol count, minimum deposit, maximum slippage, and platform fee.
