Summary
A proposal to:
- Increase CRV’s supply and borrow caps on Aave’s V3 Ethereum main instance.
- Increase cbBTC’s borrow cap on Aave’s V3 Base main instance.
- Increase weETH’s supply cap on Aave’s V3 Base main instance.
CRV (Ethereum)
CRV has reached 81% supply cap utilization and 99% borrow cap utilization.
Supply Distribution
CRV’s supply distribution does not present risks, as the three largest positions are either deposit-only or maintain strong health scores.
Only $175K of the asset’s $1M debt ceiling is currently being utilized; this also ensures that the only assets borrowed against CRV are stablecoins.
Borrow Distribution
Borrowing is also distributed and against a variety of collateral assets, with WBTC being the most popular amongst large borrowers.
Overall, wstETH is also a popular collateral asset against CRV. Given the liquidity of these assets, these positions do not present a risk to Aave.
Recommendation
Given user behavior and on-chain liquidity, we recommend doubling the borrow cap while increasing the supply cap by 50%, given that supply has not grown significantly in recent months. This increase is backed by Chaos Labs’ risk simulations, which consider the user’s behavior, on-chain liquidity, and price impact, ensuring that the higher cap does not introduce additional risk to the platform.
cbBTC (Base)
cbBTC has reached 96% borrow cap utilization.
Borrow Distribution
Borrows are highly concentrated with a single user, who is borrowing cbBTC and wstETH against cbBTC collateral, with a strong health score (given the correlation) of 1.73.
This user does not present a risk to the protocol given their low risk of liquidation.
Recommendation
Given low-risk user behavior and on-chain liquidity, we recommend doubling the borrow cap. This increase is again backed by Chaos Labs’ risk simulations.
weETH (Base)
weETH has reached 92% supply cap utilization on Base and its borrow cap is at 8% capacity.
Supply Distribution
All but two of the of the top weETH suppliers uses it as collateral to borrow WETH; the two exceptions use the asset to loop with itself. The top position represents a 25.8% of the supply, which indicates high supply concentration. However, due to the correlation between the collateral and borrow assets, none of these positions poses a significant liquidation risk.
Overall, E-Mode assets represent 98.2% of the value borrowed against weETH.
Recommendation
Given the high correlation between the borrow and supply assets, but the limited on-chain supply of weETH, we recommend increasing the supply cap to 40,000 weETH. This increase is backed by Chaos Labs’ risk simulations, which consider the user’s behavior, on-chain liquidity, and price impact, ensuring that the higher cap does not introduce additional risk to the platform.
Specification
Chain | Asset | Current Supply Cap | Recommended Supply Cap | Current Borrow Cap | Recommended Borrow Cap |
---|---|---|---|---|---|
Ethereum | CRV | 11,500,000 | 17,250,000 | 3,500,000 | 7,000,000 |
Base | cbBTC | 5,000 | - | 80 | 160 |
Base | weETH | 32,000 | 40,000 | 9,000 | - |
Next Steps
We will move forward and implement these updates via the Risk Steward process.
