Puffer Finance launched in 2024 with a specific focus on the slashing risk problem in restaking. Traditional restaking exposes validators to slashing from both Ethereum and EigenLayer AVSs simultaneously. Puffer built anti-slashing technology — using secure hardware enclaves (SGX/TDX) to protect validator keys and prevent the kind of double-signing that triggers slashing events. The pufETH token represented restaked ETH with an additional layer of slashing protection.
The PUFFER token launched in late 2024 with an airdrop to early depositors. Puffer had grown to over $1 billion in TVL during the restaking mania, attracting users who were concerned about the slashing risks that other liquid restaking protocols downplayed. The anti-slashing narrative was compelling: if you’re going to take on additional risk by restaking, having hardware-level protection against the worst-case scenario is worth something.
Puffer’s broader contribution is making the restaking risk conversation more sophisticated. Early restaking discourse was almost entirely focused on yield — how much more could you earn by restaking? Puffer shifted attention to the risk side: what happens when things go wrong? The answer — potential cascading slashing across multiple protocols — is genuinely concerning, and Puffer’s technology represents one approach to mitigating it. Whether hardware-based solutions or cryptographic approaches (like EigenLayer’s own slashing design) prove more effective is still an open research question.
