[Gauntlet] Parameter Recommendations for USDe on Mainnet USDC & USDT Comets

Simple Summary

If the community chooses to initialize USDe as collateral on the Mainnet USDC & USDT Comets, Gauntlet recommends the following risk parameters.

Comet Collateral Supply Cap Collateral Factor Liquidation Factor Liquidation Penalty
Mainnet USDC USDe 30,000,000 89% 94% 4%
Mainnet USDT USDe 30,000,000 89% 94% 4%

Analysis

DEX Liquidity

Pool Type Pool Name Pool URL TVL ($) 24H Volume ($)
Fluid USDe / USDT Link 46.67M 14.73M
Uniswap USDe / USDT 0.005% Link 15.01M 30.54M
Uniswap USDe / USDT 0.001% Link 2.58M 2.68M
Uniswap USDe / USDC 0.01% Link 2.04M 657K
Curve USDe / USDC Link 1.23M 313.25K

Note: The list above is not exhaustive, it is a summary of the largest sources of DEX liquidity at the time of review.

DEX Slippage

USDC

USDT

As seen above, a 30M cap of USDe can be swapped to USDC or USDT with less than 1% slippage.

We also note that the cumulative cap can be swapped if needed, as seen below.

Collateral Factor (CF), Liquidation Factor (LF), and Liquidation Penalty(LP)

Given the above slippage analysis, we recommend a 4% LP, which is typical for correlated assets.

USDe/USDC Volatility and Returns

USDe/USDT Volatility and Returns

As expected, typical volatility is quite low; however, we must also consider moves under a depeg event. Assuming a maximum inter-block price drop of 2% and using the standard 5% buffer between LF and CF, we recommend setting the following risk parameters on both comets to balance capital efficiency with risk mitigation:

CF = 0.89 \\ LF=0.94 \\ LP=0.04

This one slipped by me, sorry for the belated feedback.

I’m aware that Ethena has been announced as a V4 partner and am broadly supportive of that agreement in principle, subject to the final design details and corresponding risk profile. However, one thing the deUSD debacle has made abundantly clear is that many depositors truly do not understand the nature of the collateral risk exposures they take on by the simple act of supplying into stablecoin markets. Many users across the forum and socials expressed genuine disbelief that their USDC or USDT deposit had exposed them in any way to deUSD. Among stablecoin markets, I see the mainnet USDC and USDT comets as the ones that most need to be unassailable, for the reputation of the DAO.

I expect this proposal to pass; my vote against is intended to signal the continued need for the DAO to critically review not just the quantitative risk parameters, but the underlying security and asset backing models of collateral assets, especially on the mainnet USDC and USDT markets. I am not convinced that USDe’s depeg risk profile is qualitatively similar enough to that of USDC or USDT to justify its use as collateral in these markets.

Thanks for the feedback, @allthecolors.

Gauntlet’s recommendations are grounded in quantitative analysis of liquidity depth, volatility, and depeg scenarios. Since the original recommendation, liquidity conditions on Mainnet have shifted - we’ve posted updated cap recommendations accordingly.
