pufETH

The liquid restaking token issued by Puffer Finance when users participate in the protocol's native restaking system on Ethereum, representing ETH that has been natively restaked through EigenLayer while allowing participants to retain liquidity and DeFi composability. Puffer Finance was designed specifically around the native restaking model, where validators maintain custody of their withdrawal keys rather than delegating them to an intermediary protocol. The protocol's nLRT (native Liquid Restaking Token) approach, implemented through pufETH, aims to combine the security advantages of native restaking with the accessibility of liquid positions. Puffer introduced innovations including the 'anti-slashing' validator client, NoOp, designed to eliminate the risk of accidental slashing for validators in its network, and a lower effective ETH minimum through shared infrastructure that makes native restaking viable for smaller participants. Example: Puffer Finance's strategy of lowering the 32 ETH native restaking barrier through pooled validator infrastructure attracted both retail users who wanted the security properties of native restaking without running their own validator, and institutional validators who wanted to earn EigenLayer AVS rewards while maintaining more control over their withdrawal credentials than purely liquid restaking protocols like Ether.fi provide. Why it matters for Web3: pufETH represents the native restaking end of the liquid restaking token spectrum, attempting to preserve more of Ethereum's trust-minimized design while still offering the liquidity and composability that make liquid staking tokens practically useful in DeFi. Its approach influenced the broader LRT ecosystem's thinking about the security-convenience tradeoff and demonstrated that native restaking could be made accessible beyond the 32 ETH self-sufficient validator tier.
