Summary

The current implementation hardcodes the Aave referral code to 0 in supply operations, limiting the protocol's ability to participate in Aave's referral program and potentially benefit from future incentive structures.

Vulnerability Details

While not a security vulnerability per se, hardcoding the referral code:

1. Prevents the protocol from participating in Aave's referral program

2. Reduces protocol flexibility and adaptability

3. Requires contract redeployment to modify the referral code

4. May result in missed opportunities for protocol incentives

Manual Analysis

Recommendations

Implement a configurable referral code parameter with appropriate access controls.
