Puffer Finance — The Protocol Behind Liquid Restaking

Our Mission

The team behind Puffer Finance set out to solve a specific problem. Ethereum staking is powerful, but the capital sitting inside validators is idle by default. Why should security collateral do only one job when it can do two?

The Puffer Finance protocol gives stakers a way to put their ETH to work at multiple layers simultaneously. Depositors mint pufETH — a yield-bearing liquid token — and that token appreciates as staking rewards and restaking rewards accumulate over time. No lock-ups. No waiting for validator queues. Liquidity stays in the hands of the user.

Beyond individual returns, Puffer Finance aims to strengthen Ethereum's validator set. By operating with anti-slashing technology at the node level, the protocol raises the quality floor for the entire network.

Technology

Puffer Finance is built on three technical pillars. Each one matters on its own; together they form a restaking stack that is hard to replicate.

Secure-Signer

Node operators run a remote-signing module that prevents double-signing and slashable offences at the hardware level. Validators cannot be coerced into producing conflicting attestations. This is not a software rule — it is a cryptographic guarantee.

pufETH — The Liquid Token

pufETH is an ERC-20 token that auto-compounds. Every time the protocol collects staking yield, the exchange rate between ETH and pufETH shifts upward. Holders receive more ETH when they eventually redeem — no manual claiming required. The token is composable across DeFi: it trades on Curve, Uniswap, and Balancer.

EigenLayer Integration

Restaked ETH is deployed to EigenLayer Actively Validated Services (AVSs). These services pay additional fees for the security provided by Puffer Finance's validator set. Those fees flow back to pufETH holders, adding a second income layer on top of base Ethereum rewards.

Smart contracts underpinning the Puffer Finance platform have been audited by multiple independent security firms. The team publishes all audit reports publicly. Contract addresses are verifiable on Etherscan, and the upgrade process is governed by on-chain proposals — not by a multisig controlled by a handful of wallets.

Our Approach to Security

Security is not a feature list at Puffer Finance. It is a constraint that shapes every design decision from day one.

The protocol does not chase maximum TVL at the expense of risk. Operator onboarding is permissioned during early phases so the team can verify that each node is running Secure-Signer before receiving delegated ETH. Once a node has a track record, it earns a higher allocation.

Bug bounty programmes are open year-round. Researchers who discover valid vulnerabilities receive payouts on a tiered scale — critical findings can earn six figures. The Puffer Finance team responds to valid reports within 24 hours.

On the smart-contract side, the team runs a combination of automated fuzzing and manual review before any deployment. Upgrades go through a timelock, giving the community time to inspect changes before they take effect.

How the Protocol Works

Here is the flow, end to end.

Deposit ETH (or stETH / wstETH). Connect a wallet on the stake page and send ETH. The protocol accepts plain ETH as well as Lido's stETH and wrapped stETH.
Receive pufETH. The contract mints pufETH at the current exchange rate. Because pufETH compounds, you receive slightly less than one pufETH per ETH — the difference reflects accumulated yield already baked into the price.
Earn at two layers. Your ETH is delegated to vetted node operators who run Ethereum validators. Those validators earn base staking rewards. Simultaneously, the stake is restaked on EigenLayer, generating AVS fee income.
Accumulate CARROT. Holding pufETH or providing liquidity to integrated pools earns CARROT tokens — tokenised Puffer Finance points that can be redeemed inside the protocol.
Redeem when ready. Burn pufETH to receive ETH plus all accumulated yield. Redemptions are processed through Ethereum's withdrawal queue; the protocol batches requests to minimise waiting time.

The Team

The people building Puffer Finance come from backgrounds in Ethereum core development, distributed systems, and applied cryptography. Several team members contributed to client implementations before founding the protocol.

The team is small by design. Fewer than 30 full-time contributors keeps decision-making fast and accountability clear. Everyone who ships code also participates in on-call rotations — there is no separate "ops" layer insulated from the consequences of what they build.

Advisors include researchers who have worked on beacon chain specifications and MEV infrastructure. Their involvement is hands-on: they review specs, sit in on threat-modelling sessions, and occasionally contribute pull requests.

Puffer Finance is backed by venture capital firms that specialise in Ethereum infrastructure. Details of the funding rounds are public. The team does not disclose individual salaries, but compensation packages include protocol tokens subject to a multi-year vesting schedule — aligning long-term incentives with the community.

Get Involved

You do not need to be a developer to contribute to Puffer Finance. There are several ways to participate.

Stake ETH. Visit the main app and mint pufETH. Every depositor increases the decentralisation of Ethereum's validator set.
Read the docs. The help section explains mechanics, risks, and redemption in plain language.
Join governance. PUFFER token holders vote on proposals that shape the protocol's future — fee parameters, AVS whitelisting, upgrade schedules.
Run a node. Experienced node operators can apply to join the Puffer Finance operator set. Requirements include running Secure-Signer and maintaining uptime above 98%.
Report bugs. The bug bounty programme is open to anyone. Scope includes all deployed smart contracts and the Secure-Signer software.
