[ARFC] Enhancements in Aave v3 Gnosis Chain Instance

2025-03-10: This post was edited to reflect @LlamaRisk and @ChaosLabs parameters recommendations. When they differ, the most conservative one is selected.
2025-03-19: Edited sDAI parameter to no-borrowable.

Summary

This publication proposes changes in the Gnosis Chain instance to improve the capital efficiency of USDC.e and sDAI assets by promoting changes on its parametrisation.

Motivation

The Gnosis Chain’s DeFi landscape has evolved considerably since these assets were first introduced. With a vibrant ecosystem now in place, it’s time to enhance capital efficiency, reduce capital fragmentation, and create useful debt vs no risk looping within the Aave GC instance to attract more capital and increase utilisation.

USDC to USDC.e Transition:

Gnosis Chain is committed to making USDC.e (the version that aligns with Circle’s standards) the defacto version of this stablecoin within its ecosystem, by accelerating the transition from USDC and making it the major market within Aave’s GC instance (replacing xDAI). To incentivise this migration and accommodate increased capital inflows, we propose the following adjustments for USDC.e:

  • Supply and Borrowing Cap Increase: Enacted via the Risk Steward.
  • Emode Creation: Establish an Emode pairing between USDC.e and sDAI, similar to the existing sDAI/EURe Emode.

Those changes will incentivise looping strategies with USDC.e similar to those with EURe/xDAI.

To further promote the transition to USDC.e, we propose reducing the LTV factor for USDC. This measure will prevent the initiation of new borrowings using USDC, thus encouraging users to adopt USDC.e.

Summary

LlamaRisk endorses the proposed enhancements in Aave’s Gnosis market instance. These changes would make the market more efficient and enable a new use case without having a material impact on the market’s risk profile. Ultimately, the focus switch to USDC.e would also lower the asset parameter management efforts, unifying the supply and making the supply/borrow yields less volatile.

Nonetheless, to facilitate a more natural and effective transition to USDC.e, we recommend combining the reduction in LTV to 0 together with the increase in RF. This will ensure that no new borrow positions are opened using USDC while keeping current borrowers unaffected.

Lastly, considering the uncertain demand for sDAI loans, we believe a more conservative borrow cap of 4m sDAI should be initially set to match current liquidity levels. In addition, making sDAI non-borrowable in the proposed sDAI/USDC.e E-Mode would be rational as the primary use case of that E-Mode is expected to be yield-looping using sDAI as collateral and borrowing USDC.e. Therefore, we propose the following setup for sDAI/USDC.e E-Mode:

Parameters sDAI USDC.e
Collateral Yes No
Borrowable No Yes
Max LTV 90% 90%
Liquidation Threshold 92% 92%
Liquidation Bonus 2% 2%

sDAI Liquidity

At the time of writing, ~1.3M of sDAI is available to be sold for USDC.e under the 2% liquidation bonus. An additional 200k sDAI could complement this amount if wstETH and other volatile asset routes would be considered.

Source: CowSwap, March 4th, 2025

The vast majority of sDAI liquidity resides in Balancer liquidity pools, where the largest pool pairs sDAI with USDC.e and USDT for a TVL of $6.46M. Other pools include wstETH, EURe, bCSPX, and GNO, with the total liquidity TVL being $20.3M. These assets have also been onboarded to Aave’s Gnosis market. Therefore, these liquidity pools are important for stabilizing and processing potential liquidations.

Source: Balancer, March 4th, 2025

According to these liquidity levels, sDAI borrow caps must be set lower than initially proposed by @kpk. Furthermore, sDAI borrow positions should not be opened using the E-Mode to cover possible liquidity risks sufficiently. This has resulted in the recommended revisions defined in the summary section.

Discontinued Assets

While proposed changes offer an initial look at the enhancements, it is important to summarize the long-term goals of reworking the Gnosis market:

  1. USDC is to be phased out and off-boarded gradually;
  2. xDAI is to be discontinued and off-boarded gradually;
  3. USDC.e and later GHO are to become the primary stablecoins of the market.

The proposed ARFC suggests starting a gradual off-boarding of USDC, but an immediate off-boarding of xDAI may not be ideal and, therefore, is not proposed. Delaying xDAI off-boarding would help maintain market stability and improve user retention by ensuring a smoother transition. Additionally, the upcoming deployments of GHO and bCSPX will expand market use cases and prevent liquidity constraints within the Gnosis market. After that stage is complete, transitioning from xDAI could commence.

Overview

A review of proposed changes for the Aave V3 Gnosis instance.

USD//C to USDC.e Transition

Adjust USDC.e’s Supply and Borrow Cap

The proposal recommends increasing USDC.e’s supply and borrow caps to 36M and 35M, respectively, to match xDAI’s current caps. However, there is a current on-chain supply of just 11.2M USDC.e; given this relatively low on-chain supply, we do not recommend increasing the caps at this time. However, the changes discussed below are likely to generate demand for USDC.e on Gnosis, and we are thus prepared to facilitate cap increases via the Risk Steward should this demand come to fruition.

E-Mode Creation

We support the creation of an E-Mode between USDC.e and sDAI, finding that it will create a positive use case for both assets. However, we propose slightly more conservative values for LT to ensure that maximum leverage is set to an appropriate level. The values we recommend are aligned with sUSDe in the Ethereum Core instance, which has proven to be effective at both facilitating leveraged yield generation strategies and protecting the protocol during volatility. Additionally, we do not recommend making sDAI borrowable in this instance, as there is limited low-risk use associated with leveraged borrowing of a yield-generating asset.

Adjust USD//C’s Caps, LTV, and Reserve Factor

As suggested in the proposal, we concur with the recommendation to encourage migration away from USD//C. As such, we recommend reducing the asset’s supply and borrow caps, finding that they have been relatively under-utilized in recent months, with both supply and borrow amounts showing a consistent downwards trend.

We propose reducing USD//C’s LTV to 65%, a 10 percentage point reduction from its current levels. While this can be bypassed using flashloans, it serves as a helpful indication to users that the protocol is favoring one version of USDC. Along these lines, we also concur with the proposed increase of USD//C’s Reserve Factor from 25% to 40%.

Borrow Cap 11,000,000 2,000,000
Reserve Factor 25% 40%
LTV 75.00% 65.00%

sDAI Borrowability

We support making sDAI borrowable. However, we note that yield-bearing assets have historically generated very little borrowing demand outside of niche use cases. Additionally, while there is no additional risk to setting sDAI borrowable, its use as a substitute for xDAI as a borrowed asset is expected to negatively affect Aave’s DAO revenue.

We also note that borrowable stablecoin liquidity is available at a rate lower than 6% from both xDAI and USDC.e. Comparatively, sDAI would not be an appealing option for borrowers because of its built-in yield.

As such we recommend setting an initial conservative borrow cap 4M sDAI until the demand for its borrowing remain uncertain. We further support the adjustment to its Slope 2 parameters to better align it with its risk profile.

Borrow Cap 0 4,000,000

After Snapshot monitoring, the current ARFC Snapshot recently ended, reaching out both Quorum and YAE as winning option with 813.4K votes.

Therefore [ARFC] Enhancements in Aave v3 Gnosis Chain Instance has PASSED.

Next step will be the publication of an AIP for final confirmation and enforcement of the proposal.
