🟢 The simple version
Plain English — no jargon. Start here.
Puffer Finance is a liquid restaking protocol where you deposit ETH and receive pufETH — a token that simultaneously earns standard Ethereum staking rewards AND EigenLayer restaking rewards, while Puffer's anti-slashing technology (using Secure-Enclave hardware) protects your stake from the additional slashing risks that restaking normally introduces.
Restaking — the concept
Regular Ethereum staking: you deposit 32 ETH, run a validator, earn ~3-4% APY for securing Ethereum. That's it — your ETH is committed to one job. EigenLayer's restaking: your staked ETH simultaneously secures additional services (called AVSes — Actively Validated Services) built on top of Ethereum, earning additional rewards. The catch: you now face additional slashing risk — if you misbehave in an AVS, you can lose some of your ETH, on top of regular Ethereum slashing risk.
Puffer Finance is a "liquid restaking token" (LRT) protocol that handles this automatically. You deposit ETH → Puffer stakes it on Ethereum + restakes via EigenLayer + issues you pufETH as a liquid receipt → pufETH accrues value as both staking and restaking rewards flow in.
Puffer's anti-slashing innovation
Puffer's key differentiator: it uses Secure-Enclave technology (Intel SGX hardware) on its validators to make slashing-worthy behaviour technically impossible. A validator running in a secure enclave cannot sign two conflicting blocks (the most common slashing condition) because the hardware enforces it. This lets Puffer operate validators with a lower collateral requirement — as little as 1 ETH from a node operator (vs 32 ETH normally), with the rest pooled from depositors.
Is pufETH legal in India?
Yes. pufETH qualifies as a Virtual Digital Asset (VDA) under Indian law. Gains are subject to 30% tax and 1% TDS applies to qualifying trades. Staking/restaking yield received as pufETH appreciation is also taxable income. Always consult a tax professional.
🟡 A bit more detail
For when you want to go a little deeper.
pufETH vs stETH vs weETH
stETH (Lido) = standard liquid staking, ETH staking rewards only, no restaking. weETH (ether.fi) = liquid restaking token, ETH + EigenLayer rewards, ether.fi's own node operator network. pufETH (Puffer) = liquid restaking token, ETH + EigenLayer rewards, differentiates on anti-slashing Secure-Enclave tech and lower node operator collateral requirement (1 ETH). All three are liquid — you can sell them or use them in DeFi rather than waiting for unstaking. pufETH is younger and smaller than stETH (Lido is dominant at 30%+ of all staked ETH) but competitive in the restaking segment.
PUFFER governance token
PUFFER is a separate governance token for the Puffer Finance protocol (distinct from pufETH, which is the staking receipt). PUFFER token holders vote on protocol parameters: AVS selection (which EigenLayer services Puffer restakes to), fee settings, and treasury management. PUFFER launched in 2024 via airdrop to early pufETH depositors and points farmers.
Restaking stacks risk. pufETH holders face: (1) Ethereum validator slashing risk; (2) EigenLayer AVS slashing risk; (3) Puffer smart contract risk; (4) SGX hardware trust assumption. The Secure-Enclave protection reduces but does not eliminate slashing risk. Higher yield = higher risk. Live data: CoinGecko

Secure-Enclave (SGX) anti-slashing — technical
Intel SGX (Software Guard Extensions) creates a trusted execution environment on the CPU that is isolated from the rest of the system. Puffer's validator software runs inside this enclave. The critical property: the enclave has a monotonic counter that prevents a validator from signing two blocks at the same slot (double-voting). Even if the server is compromised at the OS level, the enclave's signing key cannot be extracted and the counter cannot be rolled back. This makes equivocation slashing — the most common cause of validator slashing — hardware-impossible, not just policy-impossible.
