Fiber vs MetaMask Card
A private stablecoin account or a wallet spending card?MetaMask Card adds spending to a wallet many crypto users already have. We built Fiber to remove the wallet-shaped work: non-custodial control inside an account that feels as easy as a neobank.
Start using FiberBoth preserve user control. We turn that principle into a complete everyday account; MetaMask Card extends a general-purpose wallet into payments.
Account first or wallet add-on.
| What matters | Fiber | MetaMask Card | Decision note |
|---|---|---|---|
| Asset control | We are non-custodial and cannot access your funds, while keeping wallet mechanics out of the everyday experience. | MetaMask is non-custodial. Users choose which tokens the card can draw and set a spending cap. | Both retain user control, with different permission models. |
| Privacy | We shield supported on-chain transfers, trades and earn activity with zero-knowledge proofs. | MetaMask documents wallet security, token permissions and card-provider data practices rather than shielding general wallet activity. | Compare the privacy of supported on-chain activity, separately from account security. |
| Product scope | We combine eligible US account rails, earn, private transfers and supported 24/7 tokenized markets in one account. | A Mastercard connected to supported assets in MetaMask across selected networks. | We built an integrated money account; MetaMask Card is a spending extension. |
| Fees | We charge 0% Fiber deposit and trading fees; network, spread and third-party fees can apply. | MetaMask publishes fees by token type plus possible gas, cross-border, ATM and premium-card costs. | MetaMask is more explicit today on card fee scenarios; our 0% claims apply to deposits and trading. |
| Markets and earn | We show earn live in the balance and offer supported tokenized stocks, commodities and crypto 24/7. | MetaMask can spend supported yield-bearing tokens but the Card itself is not a unified earn and tokenized-markets account. | We connect income, earn and supported markets in one account. |

Both products keep core wallet control with the user. We build a familiar account around that boundary. Integrated services can still have separate identity, eligibility and processing requirements.

Fiber shields supported transfers, trades and earn activity with zero-knowledge proofs. MetaMask documents non-custodial control, permissions and partner data practices. These address different parts of the account’s security and privacy.
