Puffer Finance entered the liquid restaking arena in 2024 with a clear differentiator: Secure-Signer, an anti-slashing technology designed to protect staked ETH from slashing risks. Its liquid restaking token, pufETH, lets users earn restaking yield while maintaining liquidity. Puffer’s second act, the UniFi based rollup, channels sequencer revenue back to the Ethereum community. As of 2026-07-15, the protocol holds roughly $48M in total value locked (DeFiLlama) across Ethereum and its UniFi chain. This review examines whether Puffer’s technical ambitions can overcome its modest scale and intense competition from EigenLayer EigenLayer and Renzo Renzo.

What it is

Puffer Finance is a liquid restaking protocol launched in 2024. It lets Ethereum holders restake their ETH via a validator network protected by Secure-Signer, a technology that reduces the risk of slashing penalties. Users receive pufETH, a yield-bearing liquid restaking token that accrues rewards from securing Actively Validated Services on EigenLayer. Beyond restaking, Puffer has built the UniFi based rollup, which returns sequencer revenue to Ethereum validators and pufETH holders. Governance is controlled by the Puffer DAO, with the PUFFER token serving as the native governance and utility asset. As of mid-2026, Puffer operates on Ethereum mainnet and its own UniFi chain, with roughly $48M in total value locked.

How it works

When you deposit ETH into Puffer’s restaking contracts, it is delegated to validator nodes equipped with Secure-Signer. This module uses threshold signatures to ensure that no single validator can sign conflicting blocks, drastically reducing the chance of slashing. In return, you receive pufETH, a receipt token that appreciates relative to ETH as restaking rewards flow in. pufETH can be used across DeFi for lending, collateral, or liquidity provision. The yield comes from EigenLayer’s AVS rewards, such as those from data availability layers, bridges, or oracles.

Puffer UniFi operates as a separate based rollup on Ethereum. It processes transactions off-chain and posts proofs to mainnet, but its key innovation is the distribution of sequencer revenue—normally captured by the rollup operator—back to the Ethereum community. In Puffer’s model, a portion of these revenues flows to pufETH holders and validators, creating an additional yield source. The protocol’s smart contracts handle minting, staking, reward distribution, and rollup bridging. All upgrades and parameter changes require governance approval via the Puffer DAO.

Key numbers

TVL: ~$48M across Ethereum and Puffer UniFi (DeFiLlama, as of 2026-07-15)
Chains: 2 (Ethereum, Puffer UniFi)
Audits: 3 (Quantstamp, Spearbit, Nethermind)
Launch: 2024
Token: PUFFER (governance)
LRT: pufETH
Incidents: None publicly reported
Peers for scale: EigenLayer ~$5B, Renzo ~$97M

Security and audits

Puffer underwent audits by Quantstamp, Spearbit, and Nethermind before its 2024 launch. As of mid-2026, no slashing events or exploits have been publicly recorded, suggesting Secure-Signer’s design is holding up. The protocol is governed by the Puffer DAO, with PUFFER token holders voting on upgrades and parameter changes. Like most early-stage protocols, administrative keys exist, but their exact configuration (multisig thresholds, timelocks) is not publicly detailed by the team. Users should note that while Secure-Signer reduces slashing risk, restaking carries inherent smart contract and AVS-related risks that audits cannot fully eliminate. The protocol’s integration with EigenLayer also exposes it to any systemic vulnerabilities in that base layer.

Strengths

Anti-slashing innovation: Secure-Signer has prevented any slashing events since launch, a claim few restaking protocols can match. This directly addresses a core risk of delegated staking.
Revenue-aligned rollup: The UniFi based rollup returns sequencer revenue to the Ethereum community, creating a potential long-term economic moat and further yield for pufETH holders.
Multi-auditor assurance: Pre-launch audits from Quantstamp, Spearbit, and Nethermind provide deeper security review than many peers, reducing the likelihood of critical bugs.

Weaknesses and risks

Modest TVL and thin liquidity: At ~$48M TVL, pufETH’s on-chain liquidity is limited, making large position exits costly and limiting its use as collateral on major lending platforms.
Limited chain coverage: Puffer is only live on Ethereum and its own UniFi chain, missing popular L2s like Arbitrum, Base, or Optimism where restaking demand is growing. This restricts composability and user access.
Unproven rollup model: The UniFi based rollup is still in early stages. Its reliance on sequencer revenue is untested at scale, and the model’s long-term sustainability is unclear. The protocol also inherits EigenLayer’s centralization and smart contract risks.

How it compares

Puffer sits in the restaking niche alongside EigenLayer EigenLayer and Renzo Renzo. At ~$48M TVL, it is dwarfed by EigenLayer’s ~$5B, but its Secure-Signer gives it a powerful differentiator in safety. Renzo (~$97M TVL) offers multi-chain liquid restaking via ezETH across seven networks, which Puffer lacks. All three have comparable audit coverage, but Puffer’s three-auditor set slightly edges Renzo’s two.

EigenLayer’s advantage lies in its first-mover status and an established marketplace of AVSs, generating network effects that Puffer cannot yet match. Renzo competes on wide chain availability and deep DeFi integrations. Puffer’s trade-off is clear: it prioritizes slashing protection and a novel rollup revenue model at the cost of scale and chain diversity. For users who value anti-slashing guarantees and are willing to accept early-stage risks, Puffer offers a unique value proposition. Those requiring maximum liquidity or broad chain access may find EigenLayer or Renzo better suited.

Verdict

Puffer Finance delivers genuine innovation with Secure-Signer and the UniFi rollup, setting it apart in a crowded restaking market. However, its ~$48M TVL, limited chain presence, and reliance on an unproven rollup model keep it in the early-adopter tier. For risk-tolerant users who prioritize slashing protection and novel yield sources, Puffer is worth watching, but it has a long road to challenge incumbents. Rating: 6.8 out of 10.

Frequently asked questions

What is Puffer Finance?

Puffer is a liquid restaking protocol on Ethereum that lets you restake ETH through its Secure-Signer anti-slashing technology. You mint pufETH as a receipt token, and the protocol also runs the UniFi based rollup to return sequencer revenue to the Ethereum community.

Is Puffer safe to use?

Puffer has been audited by Quantstamp, Spearbit, and Nethermind and has experienced no slashing events since launch. However, restaking always carries smart contract and AVS risks. Always review the latest security information before depositing.

How does Puffer make money?

Puffer generates revenue from restaking rewards distributed to pufETH holders and from sequencer revenue on the UniFi rollup. A portion of these revenues may be directed to the protocol treasury or token holders, governed by the Puffer DAO.

What chains does Puffer run on?

As of mid-2026, Puffer operates on Ethereum mainnet and its own UniFi based rollup. It does not yet support other major L2 networks.

What is pufETH?

pufETH is Puffer’s liquid restaking token. It represents your deposited ETH plus accrued restaking rewards and is freely transferable. It can be used in other DeFi protocols for lending, collateral, or trading.
