Puffer Finance
A liquid restaking protocol issuing pufETH — focused on validator-level anti-slashing tech (Secure Signer) and a long tail of operator participation.
Puffer is a liquid restaking protocol on EigenLayer. Users deposit ETH or stETH and receive pufETH, which earns Ethereum staking yield plus restaking rewards. Puffer's distinguishing feature is its emphasis on anti-slashing hardware ("Secure Signer") that prevents double-signing even when an operator's infrastructure misbehaves.
The protocol also runs its own L2 (Puffer UniFi) using LRT and based-rollup ideas. pufETH circulates as a major LRT alongside ether.fi's eETH, Renzo's ezETH, and Kelp's rsETH.
