How Does Swell Work?
An Ethereum restaking protocol offering rswETH (a liquid restaking token) and its own Layer 2 blockchain secured by restaked ETH. It holds $345M in deposits. Its B- grade reflects fast growth and a novel L2 design, offset by double slashing risk and an untested security model for the Layer 2.

Core Mechanisms
3.4.2
NovelrswETH: liquid restaking token for ETH staked on Ethereum and restaked via EigenLayer for additional yield
rswETH represents ETH staked on Ethereum beacon chain and simultaneously restaked through EigenLayer AVS services. Holders earn base Ethereum staking rewards (3-4%) plus EigenLayer restaking rewards (variable) while maintaining liquidity. Novel dual-layer yield-bearing token with compounded slashing risk.
1.2.2
NovelSwell L2 (Swell Chain): restaked rollup using EigenLayer restaking for sequencing, verification, and security
Swell L2 is a Layer 2 rollup secured by restaked ETH via EigenLayer AVS services (decentralized sequencing, verification). Built with Polygon CDK, AltLayer, EigenDA, and Chainlink. Novel 'restaked rollup' architecture differs from optimistic (Arbitrum) or ZK (Starknet) rollups by using economic security from restaking rather than fraud/validity proofs.
3.5.1
EigenLayer AVS restaking integration: Swell validators opt-in to secure EigenLayer AVS services for additional yield
rswETH holders restake via EigenLayer to earn yield from securing AVS services (oracles, bridges, data availability). Standard EigenLayer restaking integration with Swell-specific validator set.
4.2.3
EigenDA data availability: Swell L2 uses EigenDA (EigenLayer's data availability service) for rollup data storage
Swell L2 posts transaction data to EigenDA instead of Ethereum mainnet for cheaper data availability. Standard integration with EigenLayer's DA layer.
Oracle/Chainlink
Chainlink oracle integration: Swell L2 uses Chainlink for price feeds and cross-chain data
Swell L2 collaborates with Chainlink for oracle services. Standard Chainlink integration for L2 ecosystem.
5.1.1
SWELL governance token: native token for Swell protocol governance and L2 gas/staking
SWELL is Swell's native governance token, also used for L2 gas fees and staking. Standard governance token model with multi-chain utility.
How the Pieces Interact
rswETH holders face dual slashing risk: Ethereum beacon chain slashing (validator misbehavior) PLUS EigenLayer AVS slashing (oracle failure, bridge exploit). If multiple AVS services fail simultaneously (correlated bug, economic attack), rswETH loses 10-15% of ETH backing. Simple LSTs (stETH) face only single-layer slashing risk.
Swell L2 uses restaked ETH for security instead of fraud proofs (optimistic) or validity proofs (ZK). This architecture is novel and unproven at scale. If restaked security proves weaker than proof-based security, L2 users face bridge failures, censorship, or theft. No battle-testing during stress events.
rswETH is used as collateral across DeFi lending protocols. An EigenLayer AVS slashing event causes rswETH depeg, triggering cascading liquidations across all protocols accepting rswETH as collateral. Forced selling accelerates depeg, creating feedback loop between slashing losses and DeFi liquidations.
rswETH is one of fastest-growing LRTs in the market. Rapid growth means protocol reached significant scale ($292M rswETH TVL) before experiencing a full market cycle including AVS slashing events. Redemption mechanisms, oracle integrations, and validator operations are untested during acute stress.
Swell L2 security depends on rswETH value (restaked rollup model). Conversely, Swell L2 failure damages SWELL token and ecosystem confidence, reducing demand for rswETH. Bidirectional contagion means failure in either component cascades to the other, amplifying total risk beyond sum of parts.
What Could Go Wrong
- rswETH restaking via EigenLayer exposes holders to double slashing risk: base Ethereum staking slashing PLUS EigenLayer AVS slashing; a correlated AVS failure cascade could impair 10-15% of rswETH backing
- Swell L2 'restaked rollup' security model is novel and untested; relies on economic security from restaked ETH rather than fraud proofs (optimistic) or validity proofs (ZK), creating unproven attack surface for $180M L2 TVL
- Rapid LRT growth (rswETH is one of fastest-growing LRTs) means protocol mechanisms are underbattletested at scale; integration across DeFi creates systemic exposure if rswETH depegs during AVS slashing events
EigenLayer AVS Slashing Cascade Through rswETH
ModerateTrigger: Multiple EigenLayer AVS services simultaneously experience slashing events, impairing rswETH collateral backing and triggering cascading liquidations across DeFi protocols using rswETH
- 1.2-3 EigenLayer AVS services (data availability, oracles, bridges) experience correlated failures causing validators restaking through Swell to be slashed — rswETH loses 5-10% of its underlying ETH backing; price depegs from 1:1 rswETH:ETH ratio to 0.92-0.95 as slashing losses materialize
- 2.DeFi lending protocols (Aave, Morpho, Compound) trigger liquidations on rswETH collateral positions as oracle prices update to reflect depeg — Cascading liquidations force-sell $100M+ in rswETH across DEXs; depeg accelerates to 0.85 ETH as market liquidity is insufficient to absorb forced selling
- 3.Swell L2 (restaked rollup) faces security crisis as its restaked security model depends on healthy rswETH value — Swell L2 AVS services (decentralized sequencing, verification) become economically insecure; L2 users face potential bridge failures or transaction censorship
- 4.Broader liquid restaking token (LRT) market enters confidence crisis as rswETH (one of fastest-growing LRTs) demonstrates slashing risk materialization — LRT sector ($10B+ TVL across protocols) faces mass redemptions; EigenLayer restaking TVL drops 30-50% as users flee to simple liquid staking (stETH, rETH)
