# Fiber

> The Stablecoin Neobank

Fiber is a non-custodial crypto wallet focused on privacy. It lets users hold, send, and trade stablecoins and other digital assets while shielding balances and activity.

Fiber is a non-custodial crypto wallet built around privacy for everyday stablecoin use. It lets users receive, send, and trade stablecoins and other digital assets while keeping balances and transaction activity shielded from public view. The wallet targets everyday users who want practical access to onchain finance without exposing their financial activity or giving up control of their assets.

The product addresses a common tension in onchain finance: custodial platforms simplify usage but require users to trust a third party with their funds, while typical non-custodial wallets offer control but expose balances, trades, and counterparties on public blockchains. Fiber applies zero-knowledge proofs to shield supported transfers, trades, and balances, and uses throwaway addresses so activity does not collapse into a single traceable profile. Users authorize their own transactions directly, and the wallet supports deposits and activity across multiple blockchains.

Core offerings include stablecoin holding and transfers, built-in reward accrual on eligible balances, and access to trading for crypto, digital metals, and tokenized stocks, all from the same wallet. Fiber is used by individuals seeking dollar-linked savings, cross-border transfers, and market access without surrendering custody or transaction privacy.

## Products

- [Fiber](https://thegrid.id/profiles/fiber_so): Fiber is a non-custodial wallet application, positioned as a stablecoin neobank, for managing stablecoins and other digital assets on public blockchains. It lets users receive and send stablecoins, shield balances and transaction activity using zero-knowledge proofs, and accrue variable rewards on eligible stablecoin balances without giving up custody. Users can deposit USD via ACH or domestic wire for automatic conversion into stablecoins, and trade tokenized US stocks, digital metals, and crypto directly from their stablecoin balance. Wallet key material is split across separate security boundaries using secret-sharing, and users authorize each transaction rather than holding a traditional seed phrase.
