Fiat24

Fiat24 is a Swiss-regulated Web3 payment infrastructure company operating as a brand of SR Saphirstein AG, a fintech licensed by the Swiss Financial Market Supervisory Authority (FINMA) under Article 1b of the Swiss Banking Act (company registration CHE-256.014.995). Based in Zurich, Switzerland, Fiat24 bridges traditional banking systems with Web3/blockchain technology, providing what it calls the "fiat layer" for decentralised applications and crypto wallets.

Founded and operating from Switzerland's financial centre, Fiat24 won the Accenture/Qorus Best Neobank Award in 2022 and has been recognised by CVVC's Blockchain Top 50 and the WIE Startup Innovation Award. The company's mission is to re-engineer the payment landscape using Web3 technology—making blockchain-powered banking accessible to end users while offering developers and businesses a permissionless, pluggable fiat payment infrastructure.

Core Products/Services

Fiat24's flagship product is its Banking DApp — a Web3 application where users authenticate via an NFT (ERC-721 token on Arbitrum) that serves as both digital identity and account number. Core product offerings include:

• Digital Identity (NFT): Each Fiat24 account is represented by an ERC-721 NFT on Arbitrum. The NFT replaces traditional username/password authentication and acts as the user's regulated financial account identifier. Identity is KYC-verified and stored securely off-chain in compliance with Swiss law.
• Swiss IBAN Account: Multi-currency cash accounts (EUR, CHF, USD, RMB/CNH) backed by a Swiss IBAN, with transparent ERC-20 token balances on-chain. Connected to SIC/euroSIC, SEPA, and SWIFT payment networks.
• Mastercard Debit Card: Physical and digital debit card issuance via MasterCard's Principal network, supporting Apple Pay, Google Pay, and Samsung Pay. Available to users in eligible regions.
• F24 Token: A deflationary ERC-20 utility token on Arbitrum (max supply 100 million) used for minting premium NFT accounts and rewarding ecosystem participants. Wallet providers burn F24 to mint NFTs for their clients.
• Developer/Partner Integration Platform: A pluggable fiat infrastructure API and smart contract suite enabling Web3 wallets and DApps to embed Swiss banking services (IBAN, debit card, multi-currency) into their products. Developers receive revenue sharing on user top-up transactions and can issue custom-branded Mastercard debit cards to their communities.
