Idempotency checks are not performed

Informational Severity
Informational Impact
N/A Likelihood

Description

Note that idempotency checks do not exist on-chain.

Impact

Lack of an idempotency check allows for reverification of the same packet on chain.

Recommendations

We recommend performing the idempotency check as per the official LayerZero DVN documentation (point 5).

Remediation

The Polyhedra team has acknowledged this finding and provided the following clarification as response:

We perform the idempotency check off-chain before calling the verify function to ensure that the validation has not been submitted to LayerZero yet.
