Introduction

Wrapped eETH (weETH) is ether.fi's wrapped, non-rebasing version of eETH — the protocol's native liquid restaking token. It is designed to make staked ETH fully composable across the DeFi ecosystem, letting holders earn multiple reward streams without giving up liquidity.

It is widely recognized as one of Ethereum's first native liquid restaking tokens, built on top of both Ethereum's proof-of-stake consensus layer and the EigenLayer restaking protocol.

History & Background

ether.fi was founded in 2022 by Mike Silagadze and Rok Kopp with a mission to create a non-custodial ETH staking protocol where stakers retain control of their own validator keys. The protocol's mainnet launched in May 2023 with delegated staking to whitelisted validators, and eETH became open for anyone to mint in November 2023.

weETH was introduced as a DeFi-friendly wrapper around eETH, enabling the token to integrate seamlessly with lending protocols, decentralized exchanges, and other on-chain applications.

How Wrapped eETH Works

When users deposit ETH into ether.fi, they receive eETH — a rebasing token whose balance automatically grows as staking rewards accrue. Because rebasing tokens can be difficult to integrate into some DeFi protocols, ether.fi offers the weETH wrapper.

By wrapping eETH into weETH via the WeETH smart contract, users receive a non-rebasing ERC-20 token. Instead of a growing balance, the value of each weETH unit appreciates over time relative to ETH, reflecting the accumulated rewards. Users can unwrap back to eETH at any time.

ether.fi natively restakes deposited ETH through EigenLayer, meaning validators simultaneously secure Ethereum and opted-in actively validated services (AVSs), amplifying potential rewards.

Tokenomics

weETH is backed 1:1 at the protocol level by natively restaked ETH. Its value is derived from the underlying pool of staked ETH plus accumulated rewards, not from a fixed exchange rate. The token is non-custodial — stakers retain control of withdrawal credentials, and ETH can always be redeemed for eETH at a 1:1 ratio.

Rewards compound automatically and are reflected in weETH's exchange rate rather than an increasing token balance, making it tax-efficient and easy to integrate.

Ecosystem & Use Cases

weETH is accepted across a wide range of DeFi protocols on Ethereum and compatible Layer-2 networks. Holders can access four types of returns:

• Ethereum staking rewards from validator operations
• EigenLayer restaking rewards from securing additional networks
• ether.fi loyalty points distributed by the protocol
• DeFi liquidity rewards by supplying weETH to lending markets or liquidity pools

This multi-layered yield makes weETH a popular collateral and liquidity asset throughout the DeFi ecosystem.

Team, Governance & Community

ether.fi was co-founded by Mike Silagadze (CEO) and Rok Kopp. The protocol is governed in part through the $ETHFI governance token, which gives community members the ability to participate in key protocol decisions. The ether.fi Foundation oversees protocol development, with contract upgrades governed by a timelock mechanism requiring appropriate on-chain roles.

Advantages

• Multi-stream yield: Combines ETH staking, EigenLayer restaking, and DeFi rewards in one token.
• Non-custodial design: Stakers retain control of their validator withdrawal credentials.
• DeFi composability: Non-rebasing format integrates cleanly with lending protocols, DEXs, and vaults.
• Automatic compounding: Rewards accumulate in the token's exchange rate without manual action.
• Liquidity: No fixed lock-up; users can exit via withdrawal or secondary markets.

Risks & Challenges

• Smart contract risk: Bugs or exploits in ether.fi or EigenLayer contracts could affect funds.
• Slashing risk: Validator misbehavior or AVS faults via EigenLayer can lead to penalties.
• Withdrawal delays: Protocol-level waiting periods may apply depending on network conditions.
• Restaking complexity: Layered restaking introduces additional systemic risk compared to simple staking.
• Regulatory uncertainty: Evolving rules around staking and DeFi could impact protocol operations.

Long-Term Vision

ether.fi aims to evolve into a comprehensive on-chain finance platform, expanding beyond ETH staking into products like eBTC and eUSD, and a crypto-linked cash card. weETH sits at the core of this ecosystem as the primary yield-bearing asset, designed to grow in utility as restaking infrastructure matures and more AVSs come online on EigenLayer and similar platforms.
