Ether.fi

Introduction to Ether.fi

Ether.fi pioneered non-custodial liquid staking, where users maintain control of their validator keys rather than trusting a protocol. This architectural choice addresses one of liquid staking’s core concerns—key custody—while integrating seamlessly with EigenLayer restaking to maximize capital efficiency.

The protocol grew explosively during the restaking narrative, with eETH becoming one of the largest liquid restaking tokens. The combination of liquid staking, automatic restaking, and point farming created compelling user incentives that attracted billions in deposits.

How Ether.fi Works

Non-Custodial Design

Key management:

• Users generate validator keys
• Keys remain with users
• Protocol coordinates but doesn’t custody
• True self-sovereignty

Liquid Staking

eETH mechanics:

• Deposit ETH, receive eETH
• eETH represents staked ETH
• Rewards accumulate
• Liquid and composable

Native Restaking

EigenLayer integration:

• Automatic restaking
• AVS rewards
• Single token simplicity
• Capital efficiency

Conclusion

Ether.fi successfully combined non-custodial liquid staking with native restaking, creating a compelling product during the LRT explosion. The architectural choice to maintain user key custody addresses legitimate concerns about centralized staking infrastructure.

The expansion into consumer products through Cash represents an attempt to reach beyond crypto-native users. Whether Ether.fi can maintain its position as the LRT market matures and competition intensifies depends on continued product innovation and trust.

For users seeking liquid staking with restaking exposure while maintaining key sovereignty, Ether.fi provides a differentiated approach—though understanding the layered risks of restaking remains essential for informed participation.
