Pufer vs Kelp: Which Liquid Restaking Protocol Wins in 2026

Pufer vs Kelp at a glance

Skip to the section you need. Or read the full breakdown below.

Why Pufer is better than Kelp

Pufer wins on three specific axes that matter for most Liquid restaking users.

Anti-slashing technology is genuinely unique. Pufer's Secure-Signer technology enforces slashing rules at the hardware level using SGX (Intel Software Guard Extensions) trusted execution environments. The design prevents validators from signing equivocating attestations even if the validator software is compromised. This is real reduction in slashing risk for solo stakers and is unique among LRT protocols. Kelp has no equivalent technology.

Solo staker market positioning matters for Ethereum decentralization. Pufer specifically targets solo home stakers offering them anti-slashing infrastructure plus restaking yield. The mission aligns with Ethereum decentralization goals (more solo stakers = more decentralized validator set). Kelp aggregates institutional and centralized LSTs without similar decentralization thesis. For mission-aligned ETH stakers Pufer's positioning matters.

Native ETH staking integration produces cleaner yield stack. Pufer runs validators directly with anti-slashing tech meaning pufETH represents native ETH staking plus restaking yield without LST stacking. Kelp wraps existing LSTs (stETH rETH ETHx etc.) which adds dependencies on those underlying LSTs. For clean yield architecture Pufer is structurally better.

Why Kelp is better than Pufer

Kelp wins on a different set of axes. Three points where it materially beats Pufer.

Multi-LST acceptance simplifies portfolio consolidation. Kelp accepts deposits from stETH rETH ETHx and other major LSTs minting rsETH against any of them. Users with diverse LST holdings can consolidate into single rsETH position. Pufer requires depositing native ETH limiting users with existing LST positions. For LST holders Kelp is materially better entry path.

Larger TVL produces stronger DeFi integration. Kelp has ~$1.5B TVL vs Pufer's ~$1B. The TVL gap means rsETH has slightly deeper DeFi integration. KEP token launched 2024 with utility for governance and staking. For users wanting LRT with broader DeFi acceptance Kelp's slight TVL advantage matters.

Simpler architecture without hardware dependencies. Kelp uses standard smart contract architecture without dependence on hardware-based anti-slashing technology. The simplicity reduces operational risk from hardware failures or SGX vulnerabilities. Pufer's Secure-Signer adds attack surface that simpler designs avoid. For risk-averse users Kelp's standard architecture is more conservative.

Pufer vs Kelp scorecard

How Pufer and Kelp work

How Pufer works

Pufer is a liquid restaking protocol with unique positioning around anti-slashing and solo staker support. Users deposit ETH which is staked through Pufer-operated validators that use Secure-Signer hardware-based anti-slashing technology. The technology uses Intel SGX trusted execution environments to enforce slashing rules at the hardware level preventing equivocation even with compromised software. Stakers receive pufETH representing claims on the underlying ETH plus EigenLayer restaking rewards. The protocol also supports a NoOps marketplace where solo home stakers can offer their staked ETH for restaking through Pufer infrastructure. PUFER token launched 2024 with governance utility and staking-based fee capture.

How Kelp works

Kelp DAO operates a liquid restaking protocol that aggregates multiple LSTs (stETH rETH ETHx) plus native ETH into a single restaking position. Users deposit any accepted LST to mint rsETH at the LST's exchange rate. Kelp delegates the underlying staked ETH to EigenLayer operators across multiple AVSes. rsETH represents claims on the underlying multi-LST basket plus AVS rewards. The protocol's aggregator design means rsETH inherits performance from multiple underlying LST sources rather than depending on a single staking implementation. KEP token launched 2024 with governance utility.

Token economics: Pufer vs Kelp

Pufer tokenomics

PUFER launched 2024. Total supply 1B. Distribution: ~30% to community (airdrops ongoing rewards) ~30% to investors (vested) ~25% to team and contributors (vested) ~15% to ecosystem and treasury. PUFER utility: governance over Pufer protocol parameters and validator network governance. Staking captures protocol fees from validation and restaking activity. The model is similar to other LRT protocol tokens with governance plus fee accrual.

Kelp tokenomics

KEP launched 2024. Total supply 1B. Distribution: ~50% to community (airdrops liquidity rewards) ~25% to investors (vested) ~15% to team and contributors (vested) ~10% to ecosystem treasury. KEP utility: governance over Kelp DAO protocol parameters. Staking-based fee capture mechanisms have been added with revenue share to long-term stakers. The token has narrower utility than some LRT tokens but produces real fee yield during high-volume periods.

Security history and audits

Pufer security record

Pufer has been audited by Sigma Prime Quantstamp and Cantina. There have been no protocol-level exploits since launch in January 2024. The Secure-Signer hardware-based anti-slashing technology adds attack surface around SGX vulnerabilities; the protocol relies on Intel SGX security plus its own software implementation. The hardware dependency is structurally different from pure smart contract risk and requires confidence in SGX as a trust assumption. For users prioritizing slashing prevention Pufer's approach reduces operational slashing risk; for users skeptical of SGX as trust assumption it adds complexity. Bug bounty pays up to $1M.

Kelp security record

Kelp has been audited by Code4rena and Halborn. There have been no protocol-level exploits since launch in November 2023. The architecture is standard smart contract design without hardware dependencies which provides simpler attack surface analysis. The dependency on multiple underlying LSTs (stETH rETH ETHx) means rsETH inherits any risk from those underlying protocols. The aggregator design diversifies LST-specific risk but creates broader dependency footprint. Bug bounty program is active.

User experience and real fees

Pufer UX

Pufer UX at app.puffer.fi supports ETH deposits with anti-slashing infrastructure visible in the protocol description. The NoOps marketplace for solo stakers is unique offering accessible to home stakers running their own validators. Wallet support: MetaMask Rabby Rainbow and most major wallets. The interface explains the anti-slashing technology and solo staker mission. For users specifically valuing those features the messaging matches the technology.

Kelp UX

Kelp UX at kelpdao.xyz is straightforward LST deposit and rsETH minting interface. Users select which LST they hold (stETH rETH ETHx) and the protocol handles the conversion. The aggregator approach is mostly invisible to users: deposit LST receive rsETH. Wallet support universal. Mobile experience is good. The simplicity matches Kelp's positioning as accessible LRT protocol for users with existing LST holdings.

Who should use Pufer, who should use Kelp

Final verdict on Pufer vs Kelp

Pufer wins for solo stakers and decentralization-focused users. The anti-slashing technology and solo staker mission positioning produce real differentiation in the LRT category. PUFER offers genuinely different value proposition vs other LRTs not just different branding. For mission-aligned ETH stakers Pufer is the strongest choice. Kelp wins for LST holders and simpler-architecture preferrers. The multi-LST acceptance and standard smart contract design make Kelp accessible to users with existing diverse LST holdings. The slight TVL and DeFi integration advantage matters at the margin. These protocols serve smaller niches in the LRT category dominated by Etherfi. Both are credible alternatives with specific differentiators worth considering for users whose priorities align with their respective designs.
