Aave scores 9.0 out of 10 and ranks #3 of 8 in the best defi protocols table, strongest on real usage (9.4) and weakest on governance (8.4).
Has secured the largest lending book in DeFi through every crisis since 2020 without a core-protocol failure, with a risk-governance process that adjusts parameters before problems arrive. The reference implementation for on-chain credit.
4 axes, weighted as published in the table’s methodology. Each score below is read from the fact printed under it.
9.0/ 35% of the score
In production since 2020 securing the largest lending book in DeFi through every crash since, with an extensive published audit history and no exploit of its own contracts. Its risk framework did admit an asset that broke it: in April 2026 unbacked rsETH from the Kelp bridge exploit was borrowed against, leaving $177–236m of bad debt and cutting TVL by about $6.6bn.
9.4/ 25% of the score
Interest paid by borrowers is consistently positive net of incentives, and both figures are visible on-chain.
8.4/ 20% of the score
Parameters are set by token vote executed through a timelock, and governance can change risk parameters that affect existing positions; vote distribution is public.
9.2/ 20% of the score
Interest income has persisted across bull and bear conditions since 2020.
Aave has carried the largest lending book in DeFi since 2020, through every liquidation cascade, without an exploit of its own contracts. Its risk governance publishes the reasoning behind parameter changes and moves before problems arrive rather than after. When people say DeFi has blue chips, this is the protocol they mean.
The contracts performed exactly as specified. What they had been told to accept included rsETH, and when that token was minted out of nothing in the Kelp bridge exploit, borrowers took real assets against fake collateral and left Aave carrying between $177m and $236m in bad debt. TVL fell about $6.6bn in the days after. A shared pool means one listing decision reaches every depositor, and this is what that sentence costs.
Interest paid by borrowers is consistently positive net of emissions, with both figures visible on-chain. Very few protocols in this sector can say that across a full cycle.
Token votes executed through a timelock can change risk parameters affecting existing positions, and vote distribution is public. That is real power over your position, exercised slowly and in the open.
Its own contracts have never been exploited. In April 2026 it was left with $177–236m of bad debt after unbacked rsETH from the Kelp bridge exploit was used as collateral — a listing failure rather than a code failure.
Interest paid by borrowers, which has stayed positive net of token emissions across the cycle. Both figures are visible on-chain.
Yes. Token votes executed through a timelock can change collateral factors and other risk parameters that apply to existing positions.
