What is Ether.fi?
Ether.fi is a non-custodial Ethereum liquid staking protocol that has expanded into a full DeFi-native cash and spending product. It lets users stake ETH and receive liquid tokens while retaining control of withdrawal keys, and it offers a Visa card (ether.fi Cash) that lets you spend crypto balances with cashback rewards.
Core products include:
- Liquid staking: Deposit ETH and receive eETH (rebasing token) or weETH (wrapped, non-rebasing version). These tokens accrue Ethereum staking rewards and remain usable in DeFi (lending, liquidity provision, yield strategies). Note that as of mid-to-late 2026, restaking exposure was removed from the main weETH product; users seeking additional restaking must opt into separate products.
- Ether.fi Cash card: A non-custodial Visa card that spends from your crypto balances (Direct Pay prioritizes certain stables; Borrow Mode allows spending against collateral). Cashback is paid (often in ETHFI) according to membership tier.
- Additional features: Liquid vaults, membership tiers (Core, Luxe, Pinnacle, VIP) unlocked by points, staked ETHFI, or deposits, and ongoing loyalty/points mechanics.
The protocol emphasizes non-custodial design so users keep control of assets rather than handing full custody to a centralized operator.
Use The Etherfi referral code 6ef93009 when signing up for ether.fi Cash to access promotional cashback rates (often up to 15% on eligible dining, grocery, and rideshare spend for new referred users, with the referrer earning a percentage of that spend). Standard ongoing card cashback is tiered and lower. Ether.fi also offers non-custodial liquid staking of ETH via eETH and weETH.
This guide explains the platform, how the referral code works, current key features of both the staking product and the Cash card, a comparison with alternatives, step-by-step instructions, and the conditions you should confirm. Promotional rates and terms change, so always verify the latest offer in the ether.fi app or official documentation before spending or depositing.
Key Benefits of Using Ether.fi
Liquid staking with control. Stake ETH and receive a liquid token that continues to earn staking rewards while remaining transferable or usable in DeFi. You retain withdrawal key control, distinguishing the model from many custodial or more centralized staking services.
DeFi composability. eETH and weETH are integrated across major protocols for lending, borrowing, yield strategies, and liquidity provision. This lets you earn base staking yield and layer additional strategies without fully exiting the position.
Ether.fi Cash card with cashback. Spend crypto balances on everyday purchases and earn cashback. The free Core tier typically offers 3% on the first $2,000 of monthly spend (then steps down to 1% and 0.5%). Higher tiers (Luxe, Pinnacle, VIP) raise the band that earns the top rate and add other perks. Cashback is subject to monthly caps and is often paid in ETHFI after a short lock period.
Promotional elevated cashback via referral. Referral campaigns periodically offer higher rates (such as 10–15%) on specific categories like dining, groceries, and rideshare for newly referred users, with the referrer also earning a share of that spend. These are time-limited and category-restricted; the Etherfi Referral Code 6ef93009 is intended to unlock the current or recent version of such an offer.
Membership progression. Earn points through staking, holding in Liquid products, and card spend. Higher monthly points or staked ETHFI unlock better cashback bands, additional cards, and other benefits.
All staking, restaking (where available), and card activity carry risks including smart-contract risk, slashing (on staked ETH), liquidity, and market volatility of reward tokens.

| Approx. TVL | Multi-billion (top liquid restaking/staking name) | Largest by far | Smaller |
| Typical net staking yield | Competitive with peers (~2.2–2.5% range, variable) | Competitive | Competitive |
| Restaking exposure | Previously native; main product now plain staking (opt-in separate) | Via external wraps | Limited |

Many traditional crypto cards charge annual fees or offer lower base rates. Availability and exact rates vary by region; always confirm KYC, supported countries, and current terms.
