**Ether.fi Staked BTC (eBTC)** is a liquid restaking token developed by [ether.fi](https://iq.wiki/wiki/etherfi), designed to provide users with yield opportunities from both [Bitcoin](https://iq.wiki/wiki/bitcoin) [staking](https://iq.wiki/wiki/staking) and restaking protocols. It allows users to deposit [Bitcoin](https://iq.wiki/wiki/bitcoin)-backed assets, such as LBTC and [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc), to earn rewards. [\[3\]](#cite-id-eSBAscJBdR)

## Overview

eBTC functions as a [liquid](https://iq.wiki/wiki/liquid) restaking token that represents staked and restaked [Bitcoin](https://iq.wiki/wiki/bitcoin)-backed assets within the [ether.fi](https://iq.wiki/wiki/etherfi) ecosystem. Its primary purpose is to simplify the process of earning yield from multiple sources simultaneously, including native [Bitcoin](https://iq.wiki/wiki/bitcoin) [staking](https://iq.wiki/wiki/staking) and various restaking protocols. The token is designed to be compatible with multiple [blockchain](https://iq.wiki/wiki/blockchain) networks, including the [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet), [Base](https://iq.wiki/wiki/base), [Arbitrum](https://iq.wiki/wiki/arbitrum), and Corn, while maintaining the same contract address across these chains.

The token is backed by LBTC through a collaboration with [Lombard](https://iq.wiki/wiki/lombard-finance), aiming to deliver a product that offers dual yield generation from both [staking](https://iq.wiki/wiki/staking) and restaking activities. [Staking](https://iq.wiki/wiki/staking) is facilitated through the Babylon protocol, while restaking services are integrated via platforms such as [EigenLayer](https://iq.wiki/wiki/eigenlayer), [Symbiotic](https://iq.wiki/wiki/symbiotic), and [Karak](https://iq.wiki/wiki/karak). This structure allows users depositing LBTC and [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) to potentially earn yields aggregated from these different protocols. eBTC is positioned as an alternative form of [collateral](https://iq.wiki/wiki/collateral) within the growing restaking landscape, offering simplified yield optimization and expanded utility for [Bitcoin](https://iq.wiki/wiki/bitcoin) holders.

## Technology

The eBTC token operates on a technical framework that integrates multiple underlying protocols to generate yield. When users deposit supported assets, such as LBTC or [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc), into the eBTC vault, these assets are utilized across various strategies. [Staking](https://iq.wiki/wiki/staking) yield is primarily derived through integration with the Babylon protocol, which focuses on [Bitcoin](https://iq.wiki/wiki/bitcoin) [staking](https://iq.wiki/wiki/staking). Concurrently, the deposited assets are also deployed into various restaking protocols, including [EigenLayer](https://iq.wiki/wiki/eigenlayer), [Symbiotic](https://iq.wiki/wiki/symbiotic), and [Karak](https://iq.wiki/wiki/karak).

This dual approach allows eBTC holders to potentially earn rewards from both native [Bitcoin](https://iq.wiki/wiki/bitcoin) [staking](https://iq.wiki/wiki/staking) and the additional yields offered by restaking activities on [Ethereum](https://iq.wiki/wiki/ethereum)-based protocols. The system is designed to [abstract](https://iq.wiki/wiki/abstract) the complexities of managing individual [staking](https://iq.wiki/wiki/staking) and restaking positions, providing users with a single liquid token that represents their underlying staked and restaked assets, as well as accumulated rewards. The eBTC token is available and bridgeable across multiple networks, including [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet), [Base](https://iq.wiki/wiki/base), [Arbitrum](https://iq.wiki/wiki/arbitrum), and Corn, using a consistent contract address.
