Why this tier
- Meets: Operating since 2023-03 (3 years)
- Meets: Audited by 10 firms: CertiK, Omniscia, Nethermind, Solidified, Hats Finance, Zellic, Decurity, Halborn, Paladin, Certora
- Meets: Bug bounty programme (Immunefi, up to $500k)
- Meets: Large TVL: $4.8B
- Meets: No material uncovered losses in the core product (incidents in isolated products or under $1M are listed separately)
- Note: Risk of the asset itself: eETH/weETH are liquid restaking tokens: there are risks of validator and restaking (EigenLayer) slashing, discounts relative to ETH during market stress, waiting for the withdrawal queue, and, for weETH on L2, dependence on the LayerZero bridge.
- Note: Contract upgrades must pass through a 10-day timelock (getMinDelay = 864,000 seconds, read on-chain on 27/9/2026).
- Note: Following Kelp’s rsETH exploit (which did not affect ether.fi): the weETH bridge verification requirement was raised to 4/4 DVNs, weETH bridging on 8 smaller chains was halted from late 6/2026, and EtherFi Foundation contributed 5,000 ETH to DeFi United.
