# MatterFi > The universal privacy layer for digital assets MatterFi provides privacy-preserving infrastructure for crypto wallets, custody systems, and AI agents using patented stealth addresses and Send-to-Name technology. MatterFi is a fintech infrastructure company serving wallet providers, exchanges, and custodians who need transaction privacy without sacrificing compliance. Users can integrate FortressNames™ to replace wallet addresses with human-readable names resolved to cryptographically computed stealth addresses, preventing clipboard hijacks and balance exposure. White-label SDKs and a custody solution developed with Brinks Global support enterprise deployments across multiple blockchain networks. - Type: Company - Sector: Privacy & Confidentiality - Status: Active - Founded: 2020-01-01 - Profile: https://thegrid.id/profiles/matterfi ## Products - [MatterWallet](https://thegrid.id/profiles/matterfi): MatterWallet is a white-label wallet SDK that enables developers and wallet providers to embed the FortressNames™ Send-to-Name system, stealth address generation, encrypted in-wallet messaging, and off-chain KYC proof verification into cryptocurrency wallets and applications. The SDK is chain-agnostic, modular, and open source. AmericanFortress serves as the operational proof-of-concept demonstrating the full MatterWallet stack in a consumer context, with multi-chain support across Ethereum, Bitcoin, and Layer 2 networks, and infrastructure for AI agent payment integration. (Embedded Wallet, Open Beta, Main Product) - [Custody Technology](https://thegrid.id/profiles/matterfi): Custody Technology is an enterprise custody security system that combines physical asset protection with cryptographic security layers. The system removes the need for administrators to access keys directly, preventing insider theft. It implements cryptographically secured KYC and KYT verification, and maintains a full audit trail while preserving participant privacy. The product is developed in partnership with Brinks Global Services, integrating physical security infrastructure with MatterFi's cryptographic layer. (Custody Technology Provider, In Development) - [FortressNames™](https://thegrid.id/profiles/matterfi): FortressNames™ is a patented naming system for cryptocurrency that replaces wallet addresses with human-readable @names. The system resolves each @name to a dynamically computed, one-time stealth address unique to each sender-receiver pair, preventing address reuse and shielding transaction history from public blockchain observers. Balance privacy is provided through the Confidentiality Machine, which blinds sender balances without requiring mixing. Selective disclosure and decentralized KYC/AML credential proofs enable on-demand compliance verification without full identity exposure. The system operates across multiple blockchains, incorporates quantum-proof cryptography, and is available via SDK and API for integration into wallets and applications. (Decentralised Identity, Live, Main Product) ## Assets - [AmericanFortress Token (AF)](https://thegrid.id/profiles/matterfi): AF is the utility token of AmericanFortress, MatterFi's send-to-name wallet platform. It is used to reserve and lock FortressNames within the decentralized name registry and to operate the privacy-preserving signaling layer that powers send-to-name transactions. AF has a fixed supply of 10 billion tokens, deployed as ERC-20 on Ethereum and bridged 1:1 to Base.
