A private account versus a DeFi-native credit card.

What matters	Fiber	ether.fi Cash	Decision note
Asset control	We are non-custodial by architecture and cannot access or control your assets.	ether.fi Cash describes a non-custodial account where crypto remains in a user-controlled vault.	Both preserve on-chain user control, with separate roles for integrated providers.
Financial privacy	We shield supported transfers, trades and earn activity with zero-knowledge privacy.	ether.fi Cash emphasizes self-sovereignty and on-chain control, not an equivalent ZK transaction-privacy promise.	Non-custodial control is shared; private supported activity is Fiber’s differentiator.
Account model	Fiber is designed around receiving stablecoins, managing a private balance, using earn and accessing supported markets.	Cash supports direct pay from eligible vault assets or borrow mode, where crypto collateral backs card spending and interest applies.	Fiber is account-first; Cash is especially strong for collateral-backed credit.
Published fees	We charge 0% Fiber deposit and trading fees; network, spread and third-party costs can apply.	Cash publishes tier-dependent card costs, a 2% ATM fee and added FX margins that vary by membership and currency.	Model the exact card tier, currency and whether you borrow before comparing.
Markets	Supported tokenized stocks, commodities and crypto trade 24/7 with 0% Fiber trading fees.	Cash connects card spending to crypto, value-accruing stables and DeFi, rather than a private tokenized-markets account.	Fiber is broader for a private portfolio; Cash is deeper for DeFi-backed spending.

Choose Fiber if

You want a stablecoin paycheck account, not a collateral strategy.
You need ZK privacy for supported transfers, trades and earn activity.
You want tokenized stocks and commodities alongside crypto.

ether.fi Cash may be the better fit if

Cashback, Visa Signature benefits and membership tiers matter to you.
You already use ether.fi’s DeFi ecosystem and value-accruing stables.

ether.fi Cash has a clear strength Fiber does not try to imitate: sophisticated crypto-backed card credit with a substantial benefits program. Fiber’s advantage is a simpler stablecoin-income loop with ZK privacy and broader private markets.

Questions people ask

Are Fiber and ether.fi Cash both non-custodial?

Both describe the crypto layer as non-custodial. Fiber cannot access or control user assets, while ether.fi Cash describes user-controlled vault assets. Integrated providers still have separate operational roles.

Do I have to borrow to use ether.fi Cash?

No. ether.fi documents both Direct Pay, using eligible USDC or LiquidUSD balances, and Borrow Mode, which uses vault assets as collateral and can incur interest.

Which is better for rewards?

ether.fi Cash publishes up to 3% cashback and Visa Signature benefits, subject to caps, eligibility and terms. Fiber’s differentiators are privacy, 0% Fiber deposit and trading fees, and integrated private markets—not a headline card-reward rate.
