> Save, grow, spend.

ether.fi helps users stake ETH, BTC, and stablecoins while earning rewards and maintaining full control through liquid restaking tokens integrated across DeFi protocols.

ether.fi provides decentralized liquid staking and restaking for Ethereum, Bitcoin, and stablecoins. Users deposit assets to receive liquid tokens (eETH, weETH, eBTC, eUSD) that earn staking rewards, restaking yields, and loyalty points while remaining composable across DeFi protocols. The platform integrates with EigenLayer, Symbiotic, and Karak for restaking, uses distributed validator technology through SSV Network, and offers automated DeFi strategy vaults plus a crypto-native credit card.

## Products

- [ether.fi Stake](https://thegrid.id/profiles/ether_fi): Decentralized liquid staking protocol enabling users to deposit ETH and receive eETH or weETH tokens that earn staking rewards, restaking yields through EigenLayer integration, and loyalty points while maintaining liquidity for use across DeFi protocols. (Liquid Staking, Live, Main Product)
- [ether.fi Liquid](https://thegrid.id/profiles/ether_fi): Automated DeFi strategy vault system that allocates user deposits across third-party protocols to optimize yield generation through algorithmic position management, auto-compounding rewards, and dynamic rebalancing across lending, liquidity provision, and leveraged farming opportunities. (Yield Aggregator, Live)
- [ether.fi Cash](https://thegrid.id/profiles/ether_fi): Non-custodial DeFi-native credit card system enabling users to spend cryptocurrency holdings at merchants worldwide through Visa infrastructure while earning cashback rewards, with integration to ether.fi staking portfolio for collateralization and Apple Pay and Google Pay compatibility. (Card, Live)

## Assets

- [ether.fi governance token (ETHFI)](https://thegrid.id/profiles/ether_fi): ETHFI is the governance token of ether.fi. It is used to vote on protocol upgrades, economic parameters, the grants program, and to greenlight node operators. The token benefits from a buyback program funded by protocol revenue. (Governance)
- [ether.fi ETH (eETH)](https://thegrid.id/profiles/ether_fi): eETH is a liquid staking token representing staked ETH on the ether.fi protocol. It is a rebasing token where the balance automatically increases to reflect accrued staking and restaking rewards from Ethereum consensus and EigenLayer, maintaining composability across DeFi. When the protocol's oracle publishes reward reports, the total pooled ETH increases without increasing the number of shares, raising the value of each share and automatically distributing rewards to all holders. (Liquid Staking Tokens (LSTs))
- [Wrapped eETH (weETH)](https://thegrid.id/profiles/ether_fi): weETH is a non-rebasing wrapped version of eETH, the liquid staking token of ether.fi. It is used to represent staked ETH across DeFi protocols on multiple blockchains, earning Ethereum staking rewards and EigenLayer restaking yields while maintaining liquidity. Unlike eETH, where rewards increase token balances through rebasing, weETH reflects value appreciation through an increasing exchange rate, making it compatible with lending markets and liquidity pools that cannot handle balance changes. (Wrapped Tokens)
- [ether.fi BTC (eBTC)](https://thegrid.id/profiles/ether_fi): eBTC is a Bitcoin-backed liquid restaking token issued by ether.fi through a partnership with Lombard. It is used by depositing LBTC or WBTC to earn combined staking and restaking yields across multiple DeFi protocols. The token is backed by LBTC staked through Babylon, with restaking services provided through EigenLayer, Symbiotic, and Karak to generate dual yields from both Bitcoin staking and restaking simultaneously. (Liquid Staking Tokens (LSTs))
- [ether.fi USD (eUSD)](https://thegrid.id/profiles/ether_fi): eUSD is a USD-pegged stablecoin issued by ether.fi backed by USDe through a partnership with Ethena. It is used as collateral in the ether.fi Cash credit card and accepts deposits of USDe, USDC, DAI, and USDT. The token generates dual yields from Ethena's tokenized basis trade and restaking rewards through EigenLayer. (Stablecoin)
