Aave API

Aave v4 ERC-4626 vault integration.

Aave is one of the largest and most established decentralised lending protocols. Suppliers earn interest by providing liquidity, while borrowers take over-collateralised loans against it.

Aave v4 (live on Ethereum mainnet since 30 March 2026) reorganises liquidity around a central Liquidity Hub and modular Spokes. Each supplyable asset is exposed through a Tokenization Spoke — an ERC-4626 compliant vault that tokenises a Hub deposit into fungible wa{Hub}{Asset} shares (e.g. waCoreUSDC, waPrimeWETH). v4 debuts with three Liquidity Hubs: Core, Prime and Plus. Yield accrues in the Hub-derived share price; there is no explicit spoke-level fee.
