[ARFC] - Chaos Labs Risk Stewards - Increase Supply and Borrow Caps on V3 Ethereum - 01.05.2024


A proposal to increase:


  • USDT - supply and borrow cap
  • FXS - supply cap


The recommendations below were made utilizing Chaos’ supply and borrow cap methodologies and after analyzing user positions for each asset.

Please note that there are several other assets across V3 deployments with high supply and borrow cap utilization that were analyzed and do not have recommendations for an increase, given current market conditions. We maintain continuous monitoring of protocol usage and adjust our recommendations in response to evolving market conditions based on our simulations.



The supply and borrow cap for USDT on Ethereum V3 are currently at 86% and 83% utilization.

The recent increase in USDT borrows is mainly attributed to this account, which has borrowed 60M USDT against ~$110M WETH collateral.

Furthermore, there has been an increase in USDT supply, with a total of 80 million USDT added by eight distinct accounts, each supplying 10 million USDT. These accounts are currently not borrowing against their collateral. Given the size and timing of these deposits, we can assume they are connected and will continue monitoring the supply and borrow distribution ahead of additional recommendations.

Given the current supply and borrow distribution and in line with our methodologies, we recommend increasing the supply and borrow caps to 800M and 750M, respectively.


The supply cap for FXS on Ethereum V3 is currently at 84% utilization.

The recent increase in FXS supply is due to a single user supplying ~656.65K FXS, amounting to over 97% of the total supply. The user is currently not borrowing against his collateral.

Utilizing our supply cap methodology and given the debt ceiling set, we do not observe excess risk when increasing the supply cap for FXS on Ethereum. However, given the current concentration in a single user, we recommend a modest increase of the supply cap to 1.2M FXS.


Chain Asset Current Supply Cap Recommended Supply Cap Current Borrow Cap Recommended Borrow Cap
Ethereum FXS 800,000 1,200,000 500,000 No Change
Ethereum USDT 600,000,000 800,000,000 550,000,000 750,000,000

Next Steps

Once we receive feedback from @Gauntlet on the above recommendations, we will move forward to implement these updates via the Risk Steward process.

Gauntlet supports increasing the FXS supply cap as shown in the specification. We also recommend increasing the USDT supply and borrow caps to 800M and 750M, respectively. The specification section, however, recommends a USDT supply cap of 800,000, and a USDT borrow cap of 750.000.

We’ve prepared the payload to be executed via the Risk Steward process for this proposal.
