Restaking is the most innovative DeFi concept of 2025-2026. It allows using your staked ETH to secure multiple networks simultaneously, multiplying yield.

What is Restaking

Restaking allows reusing your staked ETH as security for other protocols besides Ethereum. Its like your bank deposit securing multiple banks at once.

How EigenLayer Works

EigenLayer is the pioneer protocol:

1. You stake ETH (or deposit Lidos stETH)
2. EigenLayer uses it as security for AVS (Actively Validated Services)
3. You receive Ethereum rewards + AVS rewards

Liquid Restaking

Protocols like EtherFi, Renzo and Puffer issue liquid restaking tokens (eETH, ezETH, pufETH) you can use in DeFi while your ETH generates yield across multiple layers.

Yields

Base ETH staking: ~3-4% APY Additional restaking: +1-5% APY (variable by AVS) Total potential: 4-9% APY in ETH

Risks

• Amplified slashing: if something goes wrong, you can lose ETH across multiple protocols
• Smart contract risk: additional layers = additional risk
• Complexity: hard to understand for beginners
• Nascent: technology is new and untested in severe crises

Conclusion

Restaking is fascinating but not for beginners. If you already stake ETH and understand the risks, EigenLayer can boost your yield. If not, start with simple staking on an exchange like Coinbase or Binance.
