Puffer: The pufETH Liquid Restaking Token With Anti-Slashing Tech, Reviewed
Puffer reviewed: the pufETH liquid restaking token that adds anti-slashing validator tech. How restaking works, the risks, and who it's for.
Table of contents
Liquid restaking stacks extra yield onto staked ETH, but slashing, losing principal to a validator fault, is the risk that scares people off. Puffer tackles that head-on. Its pufETH liquid restaking token earns staking plus restaking rewards while staying liquid, and Puffer layers in anti-slashing validator technology designed to prevent the faults that cause slashing. Reduced risk, stacked rewards, kept liquid, is the pitch. It lowers risk without removing it. Here is how it works and what to weigh.
What is Puffer?
Puffer issues pufETH, a liquid restaking token built on EigenLayer. You deposit ETH and receive pufETH, which earns base staking rewards plus restaking rewards while staying liquid for use across DeFi. Its defining feature is anti-slashing validator technology, secure signing and tooling designed to prevent the double-signing and downtime faults that lead to slashing. The goal is to make restaking safer at the validator level while keeping the reward-stacking and liquidity that make LRTs attractive.
Restaking normally locks ETH to secure extra services for extra yield. pufETH is a tradeable receipt for that position, so you keep liquidity, and Puffer's tooling aims to reduce the chance a node fault costs you principal.
How Puffer works
- Deposit ETH into Puffer and receive pufETH.
- pufETH accrues rewards. It represents restaked ETH earning base staking plus restaking (AVS) rewards.
- Anti-slashing tech runs at the validator layer, designed to prevent the faults that cause slashing.
- Use pufETH in DeFi or hold it, and redeem or sell when you want exposure back.
Why users choose Puffer
- Anti-slashing tooling. Validator technology aimed at reducing the top principal risk in staking.
- Stacked rewards. Base staking plus restaking yield in one liquid token.
- Liquidity kept. pufETH stays composable across DeFi.
- Ecosystem ambitions. Puffer has built toward broader infrastructure beyond the LRT itself.
When to reach for something else: for the simplest low-risk staking, a plain liquid-staking token; if you do not want restaking's added exposure at all, avoid LRTs. Puffer is for restakers who want the reward stack with risk-reduction tooling.
Risks
Reduced slashing risk is not zero risk. pufETH still carries restaking slashing risk from the services it secures, smart-contract risk in both Puffer and EigenLayer, and depeg risk if pufETH trades below its underlying, amplified if used as leverage collateral. Anti-slashing tech lowers, but cannot fully remove, validator faults. Points-driven yields can change. Understand the full stack, verify the official URL, and start with a small deposit.
How to get started
- Open the app and connect a self-custody wallet.
- Deposit ETH to mint pufETH.
- Choose to use pufETH in DeFi or hold it, weighing the extra risk of leverage.
- Start small and understand slashing and depeg risk before scaling.
Final verdict
Puffer is a thoughtful take on liquid restaking. pufETH stacks staking and restaking rewards, stays liquid, and adds anti-slashing validator technology to attack the risk that worries stakers most. Just hold the nuance: reduced slashing risk is still risk, and pufETH carries restaking, smart-contract, and depeg exposure like any LRT. If you want reward-stacked, liquid ETH with risk-reduction tooling and you understand the stack, Puffer is a strong option. Verify the URL and start small.

Frequently asked questions
What is Puffer?
Puffer issues pufETH, a liquid restaking token built on EigenLayer. You deposit ETH and receive pufETH, which earns base staking plus restaking rewards while staying liquid. Puffer's differentiator is anti-slashing validator technology aimed at reducing the risk that node faults cut principal.
What is pufETH?
pufETH is Puffer's liquid restaking token, a tradeable receipt for restaked ETH. It accrues staking and restaking rewards and can be used across DeFi as collateral or in liquidity, so you keep liquidity while the underlying position earns.
How does Puffer reduce slashing risk?
Puffer uses anti-slashing technology (secure signing and validator tooling) designed to prevent the double-signing and downtime faults that cause slashing. It reduces, but does not eliminate, slashing risk. Restaking still adds AVS slashing exposure on top of base staking.
Is Puffer safe?
Puffer is non-custodial and its anti-slashing tech aims to lower node risk, but liquid restaking still layers risk: restaking slashing, smart-contract risk in Puffer and EigenLayer, and depeg risk on pufETH. Understand the stack, verify the URL, and start small.
