ether.fi

To put users in control of their wealth by making it easy to save, earn, and spend crypto.

Built as a decentralized, non-custodial liquid restaking protocol, ether.fi has evolved into a crypto-native financial platform where users can save, earn, and spend digital assets without giving up control of their keys. The protocol manages over $6 billion in total value locked across staking products like weETH, eBTC, and eUSD that let users earn multiple reward streams while maintaining DeFi composability. Beyond staking, ether.fi offers automated yield vaults and a Visa card that lets users spend crypto balances globally without selling their underlying assets. The company operates with a builder-first culture that requires daily in-person collaboration across offices in Grand Cayman, New York, Denver, and Dubai.

Products

The core protocol offers liquid restaking tokens like weETH (restaked ETH), eBTC (restaked BTC), and eUSD (restaked stablecoins) that earn multiple reward streams while staying composable across DeFi. Liquid provides automated strategy vaults that deploy assets across DeFi protocols and real-world assets like credit pools and bond ETFs. Cash includes a non-custodial Visa card offering up to 3% cashback, 0% FX fees, and integration with Apple Pay and Google Pay. The platform also serves institutions through white-glove ETH Fund services and supports Ethereum decentralization via Operation Solo Staker, which lets users run validator nodes without upfront ETH deposits.

Funding

ether.fi has raised approximately $32 million across multiple rounds, including a $5.3 million seed round in early 2023 led by North Island Ventures and Chapter One, with participation from Arrington Capital and Version One Ventures. The company closed a $27 million Series A in early 2024 co-led by Bullish Capital and CoinFund, with backing from OKX Ventures, ConsenSys, Foresight Ventures, and Amber Group. The protocol's total value locked surged past $6 billion by mid-2024, establishing ether.fi as one of the largest protocols on Ethereum.

Recent news

In June 2026, ether.fi launched a $100 million Liquid Real-World Asset (RWA) vault in partnership with Plume Network and Midas, providing its users with access to tokenized yields from traditional financial instruments like AAA-rated collateralized loan obligations.

Technology

Smart contracts are built in Solidity and tested with Foundry, while the backend runs on Golang, Node.js/TypeScript, and Python with PostgreSQL databases. The frontend uses React and Next.js with Tailwind CSS. Infrastructure runs on AWS and GCP with hardened CI/CD pipelines via GitHub Actions and CircleCI, incorporating SAST/DAST tools and strict dependency management. Security operations use CrowdStrike for endpoint detection, ImmuneFi for bug bounty management, and comprehensive identity and access management workflows. The protocol integrates with Ethereum, EigenLayer for restaking, and distributed validator technology.

Benefits

The company requires daily office presence to foster strong collaboration, with unlimited PTO and the flexibility to work remotely for one month each year. Compensation includes competitive salaries, annual performance-based bonuses, and the option to be paid in ETH, plus meaningful equity through token allocations. Health, dental, and vision coverage is comprehensive, with additional mental health support. Employees get home office stipends, 401(k) matching, professional development budgets, and parental support. The team enjoys frequent off-site retreats to locations like Lisbon and the Cayman Islands, plus opportunities to attend major crypto conferences worldwide.
