What is Puffer Finance?
Puffer Finance is a decentralized native liquid restaking protocol built on Ethereum that combines liquid staking with native restaking through EigenLayer. Launched in 2024, Puffer distinguishes itself through innovative anti-slashing technology called Secure-Signer, which protects validators from accidental slashing events. The protocol issues pufETH, a liquid restaking token that earns both Ethereum staking rewards and EigenLayer restaking rewards simultaneously.
Puffer's mission is to make Ethereum staking safer and more accessible while enhancing network decentralization. The protocol allows node operators to run validators with as little as 1-2 ETH collateral (compared to 32 ETH for solo staking) thanks to its Secure-Signer technology that minimizes slashing risk. This dramatically lowers the barrier to entry for running validators and promotes a more distributed validator set.
The protocol has attracted significant attention from the Ethereum community for its focus on decentralization and anti-slashing innovations. By offering native restaking out of the box, Puffer allows users to earn yield from multiple sources without the complexity of manually interacting with EigenLayer.

How Puffer Finance Works
Native Liquid Restaking
Unlike protocols that issue an LST then require manual restaking, Puffer provides native liquid restaking:
- User deposits ETH into Puffer
- ETH is used to run validators with Secure-Signer protection
- Validators are automatically registered on EigenLayer
- User receives pufETH representing their restaked position
- PufETH earns staking + restaking rewards
The pufETH Token
pufETH is a value-accruing liquid restaking token:
- Represents ETH staked and restaked through Puffer
- Value increases as rewards accrue
- Earns Ethereum PoS rewards + EigenLayer restaking yields
- Fully liquid and tradeable
- Usable as collateral in DeFi
Secure-Signer Technology
Puffer's breakthrough innovation prevents validator slashing:
- Hardware-based remote signing
- Prevents double-signing accidents
- Reduces collateral requirements for operators
- Enables more decentralized validator set
- Protects staker deposits from operator errors

Risk Considerations
Smart Contract Risk
Puffer is a newer protocol with complex restaking mechanics. Despite audits, smart contract vulnerabilities could exist.
Slashing Risk
While Secure-Signer reduces risk, slashing on EigenLayer AVSs is a novel risk not yet fully battle-tested.
Restaking Risk
EigenLayer is relatively new. Restaking introduces additional smart contract and economic risks.
AVS Risk
Restaking rewards depend on AVS adoption. Early-stage AVSs may have unknown risks.
Liquidity Risk
As a newer token, pufETH may have limited liquidity compared to established LSTs.
Technology Risk
Secure-Signer is innovative but new. Hardware or software issues could impact operations.
Risk Disclaimer: DeFi protocols carry inherent risks including smart contract vulnerabilities and market volatility. Never invest more than you can afford to lose.Frequently Asked Questions
What makes Puffer different from other LSTs?Puffer combines liquid staking with native restaking and anti-slashing technology, offering enhanced yields and security features.
How does Secure-Signer prevent slashing?It uses hardware-based remote signing to prevent the double-signing errors that cause most accidental slashing events.
Is pufETH an LST or LRT?pufETH is a Liquid Restaking Token (LRT) because it includes native EigenLayer restaking, not just base Ethereum staking.
Can I use pufETH in DeFi?Yes, pufETH is integrated with various DeFi protocols for lending, liquidity provision, and other strategies.
What are the yield sources for pufETH?pufETH earns Ethereum PoS staking rewards, EigenLayer restaking rewards, and potentially AVS rewards as the ecosystem matures.
