How Does Swell Liquid Restaking Work?

Restaking|Risk C|7 mechanisms|4 interactions

Swell Liquid Restaking lets users stake ETH and receive rswETH, a token that earns both Ethereum staking rewards and additional yield from securing EigenLayer's Actively Validated Services (AVSs). Unlike regular liquid staking where your ETH only secures Ethereum, restaking puts your ETH to work securing additional services for potentially higher returns. rswETH remains liquid and usable in DeFi while the underlying ETH earns dual yields. The protocol is audited by Sigma Prime and Cyfrin with Chainlink integration for reserve verification.

Core Mechanisms

8.3.1

EigenLayer restaking of staked ETH to secure AVSs via rswETH token

Standard EigenLayer restaking model. Users deposit ETH or swETH, which is restaked into EigenLayer to secure Actively Validated Services. rswETH provides liquidity for the restaked position.

3.4.2

Novel

rswETH reward-bearing liquid restaking token

rswETH is a reward-bearing ERC-20 token representing restaked ETH. Value increases from both Ethereum staking rewards and EigenLayer restaking yields. Novel in that it compounds two distinct yield sources.

3.3.2

Curated operator and AVS selection for restaking delegation

Swell selects which EigenLayer operators and AVSs the restaked ETH secures. Users trust the protocol's curation rather than choosing individually.

3.2.1

Novel

Layered slashing exposure across Ethereum validation and AVS operations

Restaked ETH faces slashing risk from both Ethereum consensus layer and EigenLayer AVS conditions. Novel compounding of slashing exposure in a single token.

6.4.1

Multi-layer oracle for rswETH exchange rate incorporating staking and restaking yields

Exchange rate oracle must account for ETH staking rewards, AVS restaking yields, and any slashing events. More complex oracle dependency than standard LSTs.

5.1.1

SWELL token governance shared with Swell liquid staking

Governance shared across the Swell ecosystem. SWELL token used for protocol decisions affecting both swETH and rswETH products.

7.3.1

Points-based incentive system for early restaking participants

Standard points system to incentivize early adoption, with points potentially converting to future token allocations.

How the Pieces Interact

EigenLayer restaking↔Layered slashing riskHigh

rswETH holders face slashing from both Ethereum consensus and EigenLayer AVS operations. A correlated event (e.g., client bug affecting both layers) could cause double slashing, significantly reducing rswETH value in a way that pure LST holders would not experience.

rswETH as DeFi collateral↔Complex exchange rate oracleHigh

rswETH used as collateral in lending protocols requires accurate exchange rate reporting. The multi-layer yield composition (staking + restaking - slashing) makes the oracle more complex and potentially more fragile than standard LST oracles, increasing liquidation risk during volatile periods.

Points-based incentives↔TVL concentrationMedium

Points-farming attracts mercenary capital focused on airdrop maximization rather than genuine restaking utility. When points programs end, rapid TVL exodus could thin rswETH secondary market liquidity.

AVS curation↔Opaque risk allocationMedium

Users cannot directly control which AVSs their restaked ETH secures. A poorly performing or slashed AVS chosen by Swell's curation process would impose losses on all rswETH holders without their individual consent or awareness.

What Could Go Wrong

  1. rswETH represents ETH restaked into EigenLayer AVSs, creating layered slashing risk. If an AVS operator is slashed, rswETH holders bear the loss without direct control over which AVS their restaked ETH secures.
  2. The rswETH exchange rate depends on multiple oracle sources: the underlying ETH staking rate plus EigenLayer restaking yields minus any slashing. Oracle complexity increases the risk of mispriced rswETH in secondary markets and DeFi integrations.
  3. Liquid restaking creates leverage-like dynamics where the same ETH backs both Ethereum validation and AVS security. In a correlated slashing event, the loss would be amplified across both layers.

Correlated Double Slashing Event

Tail

Trigger: A validator client bug simultaneously triggers Ethereum consensus slashing and EigenLayer AVS slashing for operators secured by Swell's restaked ETH.

  1. 1.A client software bug causes multiple operators in Swell's curated set to produce conflicting attestations and violate AVS conditions simultaneously — Both Ethereum consensus slashing and EigenLayer AVS slashing penalties are applied to the same underlying ETH
  2. 2.rswETH exchange rate drops sharply as the double slashing reduces the underlying ETH backing — rswETH trades at a significant discount to its pre-incident value on secondary markets
  3. 3.DeFi protocols using rswETH as collateral trigger liquidations — Liquidation selling pressure deepens the rswETH discount, creating a negative feedback loop
  4. 4.Redemption queue grows as rswETH holders attempt to exit to ETH — Extended waiting periods force holders to accept deep secondary market discounts or remain locked
