At a glance
Aave ↗ is the dominant multi-chain DeFi money market, holding $22B in TVL across nine chains as of May 2026. Kamino Finance ↗ is Solana’s leading lending protocol, with $2.5B in TVL and a unique liquidity automation layer. The comparison is less about which protocol is superior and more about which blockchain ecosystem fits your needs: Aave for deep EVM liquidity and broad asset support, Kamino for integrated Solana-native lending and LP strategies.
Key differences
Aave runs on nine chains—Ethereum, Arbitrum, Polygon, Avalanche, Optimism, Base, Metis, BNB, and Gnosis—while Kamino is exclusive to Solana. TVL reflects this: Aave’s $22B is roughly nine times Kamino’s $2.5B. Aave launched in 2017 (as ETHLend), giving it a five-year head start over Kamino’s 2022 debut. Audits also differ in depth: Aave has been reviewed by Trail of Bits, OpenZeppelin, and Certora; Kamino by Ottersec and Offside Labs.
Beyond lending, Aave includes GHO, an overcollateralized stablecoin with $260M+ circulation, and is building a cross-chain liquidity hub in V4. Kamino pairs its lending markets with Kamino Liquidity, an automated concentrated-LP manager for Orca and Raydium pools—a feature absent from Aave. Financially, Aave generates an estimated $230–260M in annualized revenue (per DeFi Intel Research), while Kamino’s fee structure and revenue are not disclosed in our dataset.
Security and track record
Both protocols have avoided major exploits: their incident logs are clean as of May 2026. Aave’s longer runtime and three top-tier audits make it more battle-tested. Kamino’s audits are from reputable firms, but its smaller auditor count and shorter history mean less empirical stress testing. Chain risk is concentrated: Kamino is tied to Solana’s uptime and consensus, whereas Aave’s multi-chain deployment dilutes single-chain failure risk.
Fees and costs
Fees for both vary by market. Aave’s borrow costs depend on utilization and reserve factors (typically 10–35%), while Kamino charges a fee on lending and LP rewards, though exact rates are not disclosed in our data. For current APY and fee details, refer to each protocol’s official documentation.
Which should you choose
Pick Aave if you operate across multiple EVM chains, need the deepest liquidity ($22B), the widest asset selection, or want to use the GHO stablecoin and participate in the Aave DAO. It’s the default for institutional and retail lending on Ethereum and L2s.
Pick Kamino if you are a Solana-native user who wants to combine borrowing and lending with automated concentrated-liquidity strategies on Raydium and Orca. It offers an all-in-one yield platform not replicated on EVM chains, with the low transaction costs typical of Solana.
Verdict
There is no universal winner. Aave is the multi-chain lending standard; Kamino is the Solana lending leader. The deciding factor is chain allegiance: EVM/composability (Aave) or Solana/yield automation (Kamino). Evaluate based on which ecosystem you primarily use.
