Aave on Ethereum vs Base vs Arbitrum: Where Do Lending Costs and Liquidity Differ?

Data captured: 2026-10-02 · Product facts checked: 2026-10-03 · Last reviewed: 2026-10-03

Direct answer: Aave on Ethereum, Base and Arbitrum uses the same broad protocol brand but not the same market conditions. Ethereum had much deeper Aave liquidity in the captured snapshot, while Base and Arbitrum can offer much cheaper transaction costs. Users should compare the exact asset market, supply/borrow liquidity, interest rate, collateral parameters, incentives, bridge/on-ramp cost and gas—not choose solely from chain-level TVL.

Editorial disclosure: This compares the same lending protocol across three networks. Market balances, APYs and gas are time-sensitive.

Snapshot — 2 October 2026: Aave TVL was heavily Ethereum-weighted at roughly $16.1B on Ethereum, with approximately $0.56B on Base and $0.53B on Arbitrum in the strategy snapshot.

Liquidity affects borrowing and exits

A lender cares whether there is enough borrowing demand and withdrawal liquidity for the supplied asset. A borrower cares about available liquidity, collateral parameters and liquidation risk. A chain with lower aggregate Aave TVL can still be adequate for a particular stablecoin market.

Gas can matter for position management

Lending positions may require several transactions: approve, supply, borrow, repay, withdraw or add collateral. Lower L2 gas can make active management cheaper. However, moving assets from Ethereum to an L2 can add bridge or exchange-withdrawal cost.

APY is not portable across chains

Rates vary by market utilization and incentives. An Aave USDC rate on Ethereum is not the same market as Aave USDC on Base. Capture rates at the same time and distinguish base borrow/supply rate from temporary rewards.

Terenval workflow

Terenval supports Ethereum, Base and Arbitrum One. It can serve as the common wallet/network selector: connect to the verified Aave interface, confirm the chain, review approvals and gas, then monitor health/liquidation metrics in the protocol. Terenval does not set Aave rates or prevent liquidation.
