Aave vs Lido

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.

Lido is the largest liquid‑staking protocol, minting stETH and other LSTs that track underlying validator balances 1:1 minus a 10 % reward fee. Its dual‑dao governance splits responsibility between the Lido DAO and the protocol’s Node Operator Registry, reducing centralisation risk. By May 2025 over 9 million ETH—roughly 30 % of staked supply—was custodied under Lido smart contracts.
