The call was definitely initiated by an external account when the smart contract checked **msg.sender == tx.origin** and found the result was true (EOA: Externally Owned Account). Hence the `isContract` check is redundant here.

The check for `oracleCalled` in the claim function is unnecessary if `oracleCalled` is a factor in determining whether the user is claimable or not. The oracleCalled check is required, though, if the two tests are independent of one another.

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 assumes their functional correctness. However, in the real world, third parties can be compromised and this may lead to lost or stolen assets. In addition, upgrades of third parties can possibly create severe impacts, such as increasing fees of third parties, migrating to new LP pools, etc. ```solidity=752 AggregatorV3Interface public oracle; ``` - The contract `PBMaticPrediction` interacts with third-party contract with `AggregatorV3Interface` interface via `oracle`. --- ```solidity=1224 function recoverToken(address _token, uint256 _amount) external onlyOwner { ``` - The function `PBMaticPrediction.recoverToken` interacts with third-party contract with `IERC20` interface via `_token`.
