Euler is a modular Ethereum lending protocol whose Ethereum Vault Connector (EVC) and Euler Vault Kit (EVK) let anyone deploy a customized lending market; relaunched as v2 in 2024 after a fully recovered March 2023 exploit.
Pick which ERC-4626 EVK vaults to wire to your account through the EVC. Each connected collateral vault adds borrowing power.
Toggle vaults on or off. The EVC sums LTV-weighted collateral across everything you connect.
The EVC mediator is immutable; only the shared EVK vault implementation beacon is governable, behind a 4-day timelock and a 4-of-8 DAO multisig.
Live signals detected by Sentinel monitors across all five risk classes.
See each alert's affected component, root-cause analysis, and recommended action. Pro members get the full risk breakdown for every protocol.
Monolithic lending pools force every depositor to share systemic risk with every borrower; risk curation, asset listings, and parameter changes move slowly through DAO governance. Capital is bottlenecked behind a single risk envelope.
Euler v2 decomposes lending into independent ERC-4626 vaults connected by the immutable EVC. Anyone can deploy a vault with custom risk parameters, oracles, and curator. Users pick the vault that matches their risk tolerance.
Modular lending architecture (EVC + EVK) — distinct from Aave's monolithic pool and Morpho Blue's single-pair markets. Each vault is independently governed and can use any other vault as collateral. Backed by a $7.5M Cantina bug bounty and a rewritten, formally verified codebase.

DeFi Sentinel rates Euler AA with a safety score of 85/100, indicating very low risk. The score reflects five risk dimensions: smart contract & technical risk, economic design & market risk, governance & centralization, sustainability & competitive position, and reputation & social trust. Euler has 7 audits on record. As with all DeFi protocols, residual risk remains and users should review the full risk breakdown before depositing.
Euler has a DeFi Sentinel safety score of 85/100 (rating AA), last updated May 21, 2026. The score is computed across smart contract & technical risk (30%), economic design & market risk (25%), governance & centralization (20%), sustainability & competitive position (15%), and reputation & social trust (10%).
