Aave vs Ethena

Aave V3 is the third iteration of the Aave liquidity market protocol, introducing Portals for cross‑chain liquidity, High‑Efficiency (E‑Mode) lending and Isolation Mode markets to compartmentalise risk. The refactor cuts gas costs by up to 25 % and adds real‑time supply/borrow caps that can be tuned by AAVE token governance. V3 is live on Ethereum, Optimism, Arbitrum, Avalanche, Polygon, Metis and Base, collectively holding several billion dollars in deposits secured by the Safety Module.

USDe is Ethena’s synthetic dollar backed by delta‑neutral ETH perpetual hedge positions rather than off‑chain treasuries. The collateral basket auto‑rebalances between spot ETH, LSTs and short perps so the net delta remains near zero, turning staking rewards and funding rates into protocol revenue. USDe launched on Ethereum in January 2024 and surpassed $2 billion supply within five months, with deep secondary liquidity on Curve and Bybit.
