ether.fi vs Puffer Finance (2026): Full Comparison

Reviewed 2026-05-28 by DeFi Intel Research Desk

At a glance

Two liquid restaking protocols, but at vastly different scales. ether.fi ↗ commands $6B in TVL across Ethereum, Arbitrum, Base, Linea, and Blast, making it the largest LRT issuer. Puffer Finance ↗ holds $0.5B on Ethereum and its own Puffer UniFi rollup. ether.fi layers a Cash card and payments on top of restaking, while Puffer focuses on native anti-slashing tech and sequencer revenue. The decision comes down to liquidity and integrations versus security innovations.

Key differences

TVL and liquidity: ether.fi has $6B TVL, 12x Puffer’s $0.5B. This deep liquidity means tighter slippage and broader composability across DeFi. Puffer’s smaller base may limit integration depth on platforms like Aave ↗ or Morpho Blue ↗.
Chain availability: ether.fi operates on 5 chains (Ethereum, Arbitrum, Base, Linea, Blast); Puffer is on Ethereum and its own UniFi rollup only. For users spread across L2s, ether.fi offers more flexibility.
Product scope: ether.fi bundles eETH/weETH with a Cash card, Liquid vaults, and payments infrastructure. Puffer’s focus is narrower: Secure-Signer anti-slashing for validators and a based rollup returning sequencer revenue to the community.
Maturity: ether.fi launched in 2023, a year earlier than Puffer (2024). That extra year means longer battle-testing and a more entrenched position in EigenLayer ↗ AVS delegation.

Security and track record

Both protocols have undergone comprehensive audits. ether.fi was reviewed by Certik, Nethermind, and Solidified; Puffer by Quantstamp, Spearbit, and Nethermind. Neither has reported a security incident up to the analysis date. ether.fi’s earlier launch gives it a longer production history, handling higher value and more complex integrations without issue. Puffer’s Secure-Signer adds an extra layer of slashing protection not present in ether.fi’s design, theoretically reducing validator-level risk.

Fees and costs

Specific fee structures (staking fees, protocol fees) are not disclosed in our data. Users should check each protocol’s documentation for current rates. ether.fi’s broader suite—Cash card, vaults—may introduce additional fee layers compared to Puffer’s leaner restaking product.

Which should you choose

Pick ether.fi if you:

Need the deepest LRT liquidity for DeFi looping or collateral use across multiple chains.
Want a one-stop restaking hub that also offers a payments card and vault products.
Prioritize integrations: ether.fi’s $6B TVL means it’s listed on nearly every major money market and DEX.

Pick Puffer Finance if you:

Value slashing protection above all else; Secure-Signer is a unique risk mitigant.
Are interested in a based rollup that shares sequencer revenue with the Ethereum community.
Prefer a leaner, focused restaking experience without the extra consumer-finance layers.

Verdict

For most users, ether.fi is the clear winner: 12x TVL, 5-chain access, a proven track record since 2023, and an expanding ecosystem of vaults and payments. Puffer Finance is a compelling alternative for those who specifically want anti-slashing technology or exposure to a based rollup. In the LRT arena, scale currently favors ether.fi.
