Increase Deposit/Borrow Capacity for USDe/sUSDe Smart Collateral Vaults

Increase Capacity for USDe/sUSDe Vaults

Governance

Apr 2, 2025

Summary

This proposal seeks community approval to increase DEX pool caps and debt ceilings for USDe and sUSDe smart collateral vaults to meet growing demand.

Motivation

USDe and sUSDe vaults have consistently reached capacity limits, with previous cap increases filled within minutes. The 30x Ethena rewards for these vaults make them highly attractive to users, driving significant demand that current caps cannot accommodate.

Specification

DEX Pool Cap Increases

  1. sUSDe-USDT Pools:
  • Increase from 30M shares ($60M) to 50M shares ($100M) shared between sUSDe-USDT/USDC-USDT and sUSDe-USDT/USDT vaults
  1. USDe-USDT Pools:
  • Increase from 12.5M shares ($25M) to 20M shares ($40M) shared between USDe-USDT/USDC-USDT and USDe-USDT/USDT vaults

Debt Ceiling Adjustments

  • Adjust individual debt ceilings proportionally to accommodate increased collateral capacity
  • USDC and USDT lending markets are still very far from kink, with approximately $150M availability before reaching the kink point, ensuring more than sufficient liquidity to support these increases.

Key Benefits

  1. Capital Efficiency: Smart collateral provides enhanced efficiency compared to standard collateral types.
  2. Fee Generation: Increased activity will generate additional protocol fees for the protocol.
  3. Market Demand: Meets demonstrated user demand without placing excessive pressure on USDT/USDC stablecoin lending markets.
  4. Risk Management: Maintains existing risk parameters (collateral factors, liquidation thresholds) while increasing capacity.

Conclusion

This calibrated increase responds to market demand while maintaining protocol safety. The previous cap increase was filled within minutes, confirming strong appetite for the smart collateral Ethena vaults that this proposal aims to address. With substantial headroom in the USDC and USDT lending markets, this increase is well-supported by existing protocol liquidity while increasing revenue generation.

hi @ramibtc thank you for your proposal

While it is possible to increase the supply shares, increasing the debt shares shall be thoroughly assessed to avoid overexposing Fluid and its lenders to a single collateral, especially a collateral that is receiving 3rd party incentives (sats).

Users already borrowed ~$42M against susde collateral alone. And ~$73M against susde-usdt and usde-usdt collaterals. Other markets have to grow proportionally before we can significantly increase debt shares for (s)usde collateral to avoid an under-utilization after the incentives are over and people unwind their positions.
