Cap Reductions

These changes reduce the protocol’s maximum exposure to the Aave V3 Sonic and Aave V3 Aptos markets. Each cap is set to approximately 0.67x current outstanding, below present balances, so new supply and borrow are blocked while existing positions remain unaffected and can be unwound at the holder’s discretion. Current outstanding balances and cap utilization are shown below; the resulting caps appear in the Specification.

Instance Asset Supplied Supply util Borrowed Borrow util
Aave V3 Sonic USDC 3,239,392 62.3% 1,576,001 34.3%

Aave V3 Aptos sUSDe 3,885 0.8%
Aave V3 Aptos USDC 215,779 5.1% 49,384 32.9%

stS on Aave V3 Sonic and sUSDe on Aave V3 Aptos have borrowing disabled and are reduced on the supply side only. sUSDe and USDC on Aave V3 Aptos sit well below their current supply caps (0.8% and 5.1% utilization), so their proportional reductions are larger than on the other reserves.

PT-srUSDe-25JUN2026 on Aave V3 Core matured on 2026-06-25 and is redeemable at par against srUSDe. Its supply cap is set to 1, blocking new deposits while existing holders redeem at par; the reserve is collateral-only.
