Coinbase Card is easiest to understand as a spending extension of Coinbase. Fiber is designed as the financial account itself, with non-custodial control and privacy for supported on-chain activity.

A private account versus a card on an exchange balance.

What matters	Fiber	Coinbase Card	Decision note
Asset control	We are non-custodial by architecture and cannot hold, access or control your assets.	Coinbase Card spends USD, USDC or supported crypto held in a Coinbase account, with Coinbase automatically converting crypto to USD for settlement.	Fiber is user-controlled; Coinbase Card is tied to the Coinbase account and conversion flow.
Financial privacy	We shield supported transfers, trades and earn activity with zero-knowledge privacy.	Coinbase publishes account security, identity verification and card controls rather than an equivalent ZK transaction-privacy layer.	Fiber treats supported transaction privacy as an architectural feature.
Published fees	We charge 0% Fiber deposit and trading fees; network, spread and third-party costs can apply.	Coinbase publishes no card transaction or Coinbase ATM fee, but crypto conversion includes a spread and ATM operators can charge.	A zero card fee does not make the conversion spread zero.
Account scope	Eligible US account details, stablecoin deposits, private transfers, earn and supported markets live in one account.	Coinbase Card extends a Coinbase exchange account to Visa purchases and ATMs.	Fiber is paycheck-to-portfolio infrastructure; Coinbase Card is an exchange spending tool.
Markets	Supported tokenized stocks, commodities and crypto trade 24/7 with 0% Fiber trading fees.	Coinbase offers a broad centralized crypto marketplace, while the debit card spends selected account assets after conversion.	Coinbase leads on centralized crypto breadth; Fiber joins private cross-asset markets to the account.
