About Ether Finance

Ether.fi is a decentralized finance (DeFi) platform focused on maximizing the utility of digital assets through staking, liquidity strategies, and crypto-enabled spending solutions. Its core mission is to empower users by giving them full control over their crypto while enabling them to save, grow, and spend within a robust, secure, and composable ecosystem. The platform currently boasts a total value locked (TVL) of over $6.88 billion, with several high-yield options such as 3.4% for staking, 9% from liquidity vaults, and 3% cashback through its crypto credit card.

Staking is the foundation of ether.fi’s offerings. Users can stake ETH, BTC, or stablecoins via value-accruing restaking tokens like weETH, eBTC, and eUSD. These allow holders to earn rewards while retaining liquidity and exposure to the underlying assets. Security is a top priority, with the platform being decentralized, audited, and battle-tested. The protocol is open source and supported by top-tier DeFi integrations including Aave, Pendle, and Gearbox.

The Liquid product automates yield strategies through smart vaults that auto-balance and compound returns across DeFi’s best-performing protocols. Users can choose vaults tailored to their asset types or risk profiles, maximizing returns with minimal management.

Ether.fi Cash introduces a non-custodial credit card with 3% cashback on all purchases. It integrates seamlessly with Apple Pay and Google Pay, offering global usage at over 100 million locations. This card is part of the platform’s goal to bridge DeFi with real-world utility.
