ether.fi

ether.fi receives a C- risk grade (56/100) from Hindenrank, where lower scores indicate lower risk. Elevated risk — novel restaking mechanics with live socialized slashing exposure and a neobank card product that introduces regulatory complexity and banking partner dependency, partially offset by a clean 3-year track record, $166M in annualized revenue, and 28 audit reports. ether.fi is the second-largest liquid restaking protocol globally with $5.77B in deposits, offering eETH — a liquid token that simultaneously earns Ethereum staking rewards and EigenLayer restaking rewards — alongside ether.fi Cash, a Visa debit card product that allows users to spend DeFi yields with up to 3% cashback. Its C- grade reflects three novel mechanisms: EigenLayer restaking with socialized slashing across all eETH holders (live since April 2025), non-custodial ECIES/IPFS validator key management, and Borrow Mode (a DeFi CDP-backed Visa card). Elevated regulatory risk stems from the April 2025 neobank pivot and the Cash product's dependency on undisclosed banking partners and Visa network compliance. Despite ~$166M in annualized protocol revenue and 28 audit reports with Certora formal verification, the combination of restaking complexity and consumer financial product regulation places this above typical liquid staking protocols.

The key risks identified for ether.fi are: (1) EigenLayer restaking exposes all eETH holders to AVS slashing: if an Actively Validated Service that ether.fi participates in is found misbehaving, the resulting slashing penalty distributes proportionally across all eETH holders. EigenLayer's live slashing system (since April 2025) makes this an active, not theoretical, risk. (2) Borrow Mode card users face collateral liquidation risk: depositing ETH or eETH as collateral to borrow USDC via Aave for Visa card spending means a 30-40% ETH price drop can trigger automatic liquidation of collateral through Aave's standard liquidation engine. Active position monitoring is required. (3) eETH withdrawal queue pressure during market stress: EigenLayer's 7-day unbonding period means simultaneous mass exits cannot be fulfilled immediately. During market stress, eETH may trade at a discount on secondary markets while the withdrawal queue clears, with knock-on effects on weETH collateral valuations in Aave and Morpho. (4) The Cash product depends on undisclosed banking and card-issuer partners: regulatory action against these partners, or geographic restrictions expanding, could disable the card product and force immediate unwinding of Borrow Mode positions for 70,000+ active cardholders — potentially during adverse market conditions. (5) The ongoing OP Mainnet migration (announced February 2026) introduces an operational transition period for $160M+ of Cash product TVL and 70,000 active cards, with migration bridge risk during the transition window.

ether.fi scores 56/100 across eight risk dimensions: Mechanism Novelty: 9/15, Interaction Severity: 18/20, Oracle Surface: 5/10, Documentation Gaps: 2/10, Track Record: 3/15, Scale Exposure: 9/10, Regulatory Risk: 6/10, Vitality Risk: 4/10. The highest risk area is Interaction Severity at 18/20.
