Simple Summary

This proposal releases the 50’000 USDC pre-approved by the Aave community on forum and Snapshot to the Hacxyc team, for their finding concerning a misconfiguration on Aave v3 fallback oracle.

Abstract

During the past month of April, the security firm Hacxyk disclosed to the Aave community a misconfiguration on the fallback oracle used for Aave v3 pools across markets. This disclosure was analysed from a technical perspective and a bounty proposed to the Aave community to approve HERE. After having support in both forum and Snapshot, this on-chain proposal will release the pre-approved 50’000 USDC to Hacxyk.
