50-53: Consider adding tests for cap enforcement.Ensure test coverage for the following scenarios:
- Transactions with zero caps (should fail)
- Transactions at the cap limit
- Transactions below and above the cap
52-52:⚠️ Potential issueVerify the intended behavior change with zero caps.
The modification to
shouldNotExceedCapchanges how zero caps are handled:
- Previously: Zero cap meant no limit
- Now: Zero cap means no transactions allowed
This is a breaking change that needs careful consideration.
✅ Verification successful
Zero cap behavior change is intentional and secure.
The modification to enforce zero caps as "no transactions allowed" aligns with the PR objective of implementing stricter value caps for the preview release. The governor maintains full control to set appropriate caps via
changeAmountCap.🏁 Scripts executed
The following scripts were executed for the analysis:

The value cap will be lifted later for the full launch.
PR-Codex overview
This PR refines the
shouldNotExceedCapmodifier in theEscrowUniversalcontract by removing an unnecessary check for a zero cap. It simplifies the condition to only check if the_amountexceeds the cap for the specified token.Detailed summary
