Summary

This proposal presents Aave the opportunity to onboard CRV to the Ethereum v3 Liquidity Pool.

Abstract

CRV is a strategic asset to Aave and any CRV earned from the pool could be used by Aave to create veCRV for the purpose of bootstrapping the adoption of GHO, the new staked aToken being developed by @AaveCompanies and in the long term, might help incentivize the Safety Module too.

The risk parameters provided within are the same as those provided by Gauntlet within the initial forum post discussing which assets to onboard to v3 Ethereum.

By presenting each asset to be onboarded to v3 Ethereum individually, the community can focus on a specific asset, with individual Snapshots determining how to proceed. Finally, approved assets listings can be grouped for the on-chain AIP vote.

Motivation

Listing CRV on Aave v3 Ethereum compliments the community’s recent on-market purchase of CRV to repay the excessive debt created on v2 Ethereum. CRV is a material contributor to Aave’s revenue through the continual borrowing demand for CRV. Month on Month revenue has fallen significantly as a result of disabling borrowing on the Ethereum v2 deployment.

There is strong ongoing borrowing demand for CRV due to the veTokenomics and the extrinsic use cases created by Convex Finance and projects built on top of veCRV. The chart below shows how freezing the CRV on Polygon v2 and disabling boring on Ethereum v2 during late November 2022 has affected deposit rates on Polygon v3. The Polygon v3 deployment is the only liquidity pool with Borrowing enabled, as a result there has been notable volatility in deposit rates.

By listing CRV on Ethereum v3, with Borrowing Enabled and a suitable BorrowCap users will have the ability to migrate from v2 to v3 and borrow CRV, generating revenue for Aave. Any CRV earned by Aave can be used to create veCRV, assuming Aave has access to the Curve voter escrow contract, which can then be used to vote CRV incentives to any combination of pools chosen by the community. How the CRV will be used is open for Aave to discuss and implement via a future proposal.

For listing CRV, this proposal uses risk parameters suggested by Gauntlet on the original [ARC] Aave v3 Ethereum Deployment: Assets and Configurations post. The interest rate curve parameters have been sourced from @Llamaxyz’s [ARFC] CRV Interest Rate Curve Upgrade post, which is soon to be presented on Snapshot for voting.
