Hooked.io - Eco & Sale

Performing integer division before multiplication truncates the low bits, losing the precision of calculation. ```solidity=100 return totalAllocation / 10 + (totalAllocation * 9 / 10 * elapsedTime) / _unlockTimestamps.length; ```

The imported `Address` library is never used in `PrivateSale` and `Ecosystem` contracts.

The releasable token addresses in contracts are stored in the immutable variable `_token`, making the parameter `token` in the `releasedAmount()` function redundant.

The contract is serving as the underlying entity to interact with one or more third party protocols. The scope of the audit treats third party entities as black boxes and assume their functional correctness. However, in the real world, third parties can possibly create severe impacts, such as lock tokens, etc. ```solidity=78 function releasedAmount(address token, uint64 timestamp) public view virtual returns (uint256) { ``` - The function `Ecosystem.releasedAmount` interacts with third party contract with `IERC20` interface via `token`. --- ```solidity=76 function releasedAmount(address token, uint64 timestamp) public view virtual returns (uint256) { ``` - The function `PrivateSale.releasedAmount` interacts with third party contract with `IERC20` interface via `token`.

One or more state variables are never used in the codebase. - Variable `_released` in `Ecosystem` is never used in `Ecosystem`. - Variable `_released` in `PrivateSale` is never used in `PrivateSale`.
