Protocol Deep Dive

EtherFi weETH & eETH

EtherFi is the largest liquid restaking protocol by a wide margin — $6.2B TVL reflects its battle-tested security model and innovative dual-token architecture. What sets EtherFi apart is the combination of solo restaking (via its Node DAO) and liquid restaking (via eETH/weETH), plus the guardian network that can proactively halt slashing before it occurs. No other LRT protocol offers this level of slashing protection.

🪙 The Dual-Token System

EtherFi's two tokens serve different purposes. Understanding when to use eETH vs weETH is key to optimizing your restaking strategy.

eETH
Rebasing
Balance increases each epoch — similar to stETH
weETH
Wrapper + Insurance
Wrapped eETH with delegated slashing insurance

🛡️ Guardian Network — Proactive Slashing Protection

EtherFi's guardian network is unique among LRTs — it can detect and halt slashing events before they execute on-chain, protecting user funds from operator mistakes.

✓ 2-of-N Multisig Guardian ✓ Proactive Detection ✓ Slashing Halt Capability ✓ weETH Insurance Coverage

🏛️ Node DAO Architecture

How Node DAO Works
  1. Node operators stake NODE tokens as collateral
  2. Operators are assigned to validate on behalf of stakers
  3. Misbehavior → NODE tokens slashed first
  4. User ETH only touched if NODE reserve depleted
  5. Guardian network monitors for misbehavior signals
Guardian Network Features
  • 2-of-N guardian nodes across regions
  • Continuous validator behavior monitoring
  • Can halt slashing before on-chain execution
  • Protects weETH holders specifically
  • First line of defense vs reactive slashing

🔄 Solo Restaking + Liquid Restaking Flow

EtherFi combines two restaking paths in one protocol — solo restakers operate their own validators while liquid restakers use eETH/weETH.

⚖️ eETH vs weETH — Which Should You Use?

Feature eETH weETH
Token Type Rebasing Wrapped + Insurance
Balance Growth Automatic each epoch Wrapped + accrued
Slashing Insurance Basic (Node DAO) Delegated via Guardian
Best For Passive yield, DeFi composability Long-term holders, risk-averse
Fee 10% of rewards 10% + insurance premium
Wrap/Unwrap N/A (native token) 1:1 wrap from eETH
