Why Ether Fi
Most crypto platforms force you to choose between earning yield and spending freely. The Ether Fi platform handles both. Here is what truly sets it apart.
Non-custodial from the ground up
You hold your keys. The protocol never takes control of your ETH or USDC. Not even the team behind Ether Fi can move your funds without your signature.
Genuine staking yield
Deposit ETH and receive weETH — a token that accumulates Ethereum validator rewards automatically. No lock-ups. No manual claiming.
Spend without liquidating
The Ether Fi Cash Visa card lets you make purchases using your collateral. Your assets keep earning while you spend. That is genuinely valuable.
Audited smart contracts
Contracts adhere to the ERC-4626 vault standard and are reviewed by independent security researchers before every major release.
How It Works
Connect your wallet
Use MetaMask, WalletConnect, or any EVM-compatible wallet. No account signup and no email address required at this stage.
Deposit ETH or USDC
Select your asset. ETH gets staked and you receive weETH. USDC enters the Liquid Reserve vault, also generating yield. Both run on Ethereum mainnet; bridging from Polygon is supported.
Earn passively
Staking rewards accumulate in weETH. USDC earns a variable APY through the Liquid protocol. Track everything in the vault dashboard.
Get the Cash card
Apply for the Ether Fi Cash Visa card inside the app. Once approved, enable Borrow Mode to spend against your collateral — or top up directly with USDC.
Spend and earn cashback
Use the card anywhere Visa is accepted. Earn up to 2 % cashback on every transaction. Refer friends via the affiliate programme for an additional 1 % on their spending.
Key Features
Liquid staking (weETH)
Stake any amount of ETH. Receive weETH, which is liquid and tradeable on Uniswap v3 pools. Unstake at any time through the protocol's withdrawal queue.
ERC-4626 vaults
All yield-bearing positions use the Ethereum ERC-4626 tokenised vault standard, making them composable with third-party DeFi protocols.
Borrow Mode
Put your weETH or USDC to work as collateral. Borrow against it to fund card purchases without triggering a liquidation cascade — each asset has a defined LTV ceiling.
Cash card with Visa
Physical and virtual Visa cards issued globally. Transactions settle in USDC. No foreign-transaction fee on standard purchases.
Promotions & cashback boosts
Limited-time campaigns — such as the Dine Different promotion — offer up to 15 % cashback on groceries and restaurants for active cardholders.
Travel perks
Premium membership unlocks lounge access, hotel benefits, and dedicated travel assistance. No annual fee at the standard tier.
Referral programme
Share your invite link. You earn 1 % on every card purchase your referred friends make — paid in the same currency they use.
Ether Fi by the Numbers
FAQ
What is Ether Fi?
Ether Fi is a non-custodial liquid staking protocol on Ethereum. You deposit ETH, receive weETH, and retain full control of your keys at all times. Think of it as a savings account where you remain the sole signatory.
How do I get started with Ether Fi?
Connect your wallet at the Ether Fi app, deposit ETH or USDC, and your assets begin generating yield immediately through the vault. The entire onboarding process takes under five minutes.
Is Ether Fi safe and audited?
Yes. The Ether Fi protocol has undergone audits by multiple independent security firms before each major upgrade. Smart contracts follow the ERC-4626 vault standard, which enforces well-tested accounting logic.
What is the Ether Fi Cash card?
The Ether Fi Cash card is a Visa credit card. It enables you to spend your crypto holdings at any merchant worldwide without selling your assets. Settlements occur in USDC behind the scenes.
Can I earn cashback with Ether Fi?
Yes. Cardholders earn up to 2 % cashback on purchases. Referring friends adds an extra 1 % on their card spending. Seasonal promotions can push that rate even higher — sometimes up to 15 % on specific categories.
What is weETH?
weETH is the wrapped, rebasing liquid staking token issued by Ether Fi. It accumulates staking rewards automatically and can be deployed across DeFi protocols — including Uniswap liquidity pools — without unstaking first.
How does borrowing work on Ether Fi?
In Borrow Mode you use your vault assets as collateral to borrow USDC for card purchases. Each asset carries a specific Loan-to-Value ratio. Borrowing typically does not trigger a taxable disposal in most jurisdictions, but you should verify your local regulations.
Which networks does Ether Fi support?
Ether Fi operates primarily on Ethereum mainnet. It also supports bridging from Polygon and several other EVM-compatible chains. The roadmap includes additional Layer 2 integrations in 2025.
Why should I choose Ether Fi over a centralised exchange?
You never surrender custody. Your ETH remains in a non-custodial vault. The protocol cannot freeze or seize your funds. Centralised exchanges can — and sometimes do — suspend withdrawals without warning.
Can I use Ether Fi if I am new to DeFi?
Absolutely. The Ether Fi platform is built with newcomers in mind. You can start with USDC, bypass staking entirely, and simply use the Cash card for day-to-day spending. No technical jargon required at entry level.
How do I withdraw funds from Ether Fi?
Navigate to your vault, click Withdraw, and select instant or standard unbonding. Instant withdrawals draw from a liquidity pool and settle within minutes. Standard unbonding follows the Ethereum validator exit queue — typically up to seven days.
What fees does Ether Fi charge?
Ether Fi charges a 10 % fee on staking rewards only — never on your principal. There are no monthly card fees for the standard membership tier. Premium tiers with travel perks carry an annual fee.
Is Ether Fi available in my country?
The protocol itself is accessible globally to anyone with an Ethereum wallet. The Cash card is available in most countries where Visa is accepted, though a handful of regions face regulatory limitations. Check the app to confirm your eligibility.
