Fiat24 is a Swiss‑regulated fintech that runs its ledger and payments fully on Arbitrum as a Web3‑native bank. It uses NFT‑based digital identities to represent user accounts and replaces traditional logins with wallet signatures. It then links crypto wallets to fiat balances, IBANs, and debit cards so users can pay and move money across chains.
Fiat24 is a licensed Swiss fintech that stores KYC and risk data in regulated, on‑premise systems, not on‑chain. It relies on Arbitrum’s Ethereum‑grade security, smart‑contract‑based accounting, and non‑custodial wallet access to protect funds. This combination makes it a compliant, secure PayFi platform for crypto‑linked payments and digital identity.
First, complete KYC on the Fiat24 platform and mint or receive a Fiat24 NFT in an Arbitrum‑compatible wallet. Then connect that wallet to the Fiat24 dApp to access your IBAN, fiat balances, and card features. Finally, top‑up with crypto or fiat, exchange currencies, and spend via the debit card or P2P payments.
Fiat24 offers Swiss IBAN accounts, fiat‑denominated asset tokens, cross‑border payments, and a crypto‑linked Visa‑branded debit card. Users can store and swap USD24, EUR24, CHF24, and CNH24 while using the wallet‑based interface to pay online and in stores. It also provides NFT‑based digital identity, developer tools, and fiat infrastructure for Web3 projects and dApps.
