**Summary**

Upgrade Compound v3 USDC Asset in the collateral basket for hyUSD on Base. An on-chain proposal has been created, and will go live for voting in 2 days: [Reserve app | DTFs](https://register.app/#/governance/proposal/72793447372754346397826940657624546574924428532424965645421183986408715917887?token=0xCc7FF230365bD730eE4B352cC2492CEdAC49383e&chainId=8453)

**Abstract**

A small bug in the current wcUSDCv3 asset contract results in an integer overflow, affecting the rewards that are claimable. Nothing apart from COMP rewards are at risk.

**Problem Statement**

Currently COMP rewards are not claimable due to an integer overflow bug.

**Rationale**

This upgrade will allow COMP rewards to be claimed going forward. More details can be seen in the pull request here: [Wcusdcv3 rewards fix by tbrent · Pull Request #1016 · reserve-protocol/protocol · GitHub](https://github.com/reserve-protocol/protocol/pull/1016)

**Risks**

The risks lie in not upgrading, as both the hyUSD holder and RSR staker are negatively impacted by not receiving any revenue from the COMP rewards. Currently about $2k COMP rewards have been lost from this bug, which fortunately represents only a fraction of the total yield that hyUSD has generated.
