This section documents the codebase changes made to address two issues identified during the Code4rena audit competition. The review focused solely on verifying the fixes for these findings. Both issues have been resolved, and the applied changes do not introduce any new security concerns.

1. An agent could anticipate the payment reference that would be required in a future block and could make transfers on the underlying chain. The agent could then submit the redemption request before the underlying transaction is proven illegal. If the redemption request is made before the payment, the transfer could not be proven illegal and the redemption could not be confirmed.

2. If the address of WNAT is modified by the asset updater in the Flare Time Series Oracle (FTSO), the address on the asset manager could be updated by anyone, but the address on the collateral pool could only be updated by the agent. If an agent does not update this address in a timely manner, it might have caused some accounting issues.

We were asked to review two minor patches to Flare FAssets from October 16th to October 17th, 2025, which fixed the two issues described further in Section ref.
