Fiat24 Review: Is Its Wallet-Linked Account Worth Using?

Fiat24 is a payments service from Swiss company SR Saphirstein AG. It presents an NFT as your Web3 identity and links that identity to a multi-currency cash account with a Swiss IBAN and debit card. The stated aim is to let you manage fiat cash alongside a crypto wallet and make payments. Fiat24 also describes services for businesses and developers, including a Swiss IBAN for Web3 businesses and fiat infrastructure integrations.

The current catch is decisive for new users: Fiat24 says it is in maintenance mode and is not accepting applications. That means you cannot rely on being able to open an account now, even if the product features appeal to you. The site does not give a date for reopening, so check its status before planning around a new Fiat24 account.

Fiat24 does not publish current personal or business account charges, card fees, currency-conversion costs, or transfer fees in the details reviewed here. Its site has a pricing section, but you should confirm the actual charges and applicable terms directly before relying on an existing account or applying if sign-ups resume.

There may also be blockchain costs when you use a wallet: transactions on Arbitrum can require network gas, with the amount depending on network conditions and the transaction. Wallet connection or signing alone is not necessarily the same as submitting an on-chain transaction; Fiat24 says signing to access data has no cost or gas charge. Do not mistake the displayed F24 price for the total cost of using the account, card or payment services.

Fiat24 identifies SR Saphirstein AG as incorporated in Switzerland and says it holds a fintech licence as a financial institution under Article 1b of the Swiss Banking Act, supervised by FINMA. That is a meaningful regulatory disclosure, but it does not by itself explain how your funds are held, what happens if the provider fails, or whether a particular balance has deposit protection.

Fiat24 does not explain its custody arrangements or publish an audit in the details reviewed here. Before keeping money in an account, read the legal terms for the entity responsible for your balance, safeguarding arrangements, and dispute process. The company’s Swiss registration and stated supervision are relevant, but they are not a substitute for understanding those account-level protections. Avoid depositing funds until you can verify the current terms and how withdrawals work.

To connect, Fiat24 instructs users to connect a wallet and says the wallet should be on the Ethereum Arbitrum network. Its interface includes a wallet sign-in flow and describes signing to access account data as free of cost and gas. That is different from approving a transaction or sending assets, which can involve network fees and wallet permissions.

Fiat24’s product description includes an NFT-based identity, a Swiss IBAN and a debit card, but it does not provide enough detail here to confirm card network, supported currencies, delivery regions, mobile-app availability, or payment and withdrawal speeds. Nor does it publish the current application requirements. If you already have an account, review its latest instructions and permissions before connecting a wallet; never sign a message or transaction you do not understand.

The biggest limitation is that new applications are currently closed. That makes Fiat24 unsuitable if you need a new account for an upcoming payment, card purchase or business launch. Existing users may still need to verify which services remain available during maintenance; the notice does not spell out whether account access, cards, transfers or withdrawals are affected.

Other important details also need checking before you rely on the service: current fees, eligibility and KYC requirements, supported currencies, account-fund custody, withdrawal limits and processing times. Fiat24’s F24 points are described as a way to upgrade account levels or mint preferred account numbers, with a maximum supply of 100 million. The site also shows a buy option, but the reward-points description is not enough to establish their cash value, transferability or redemption terms.

If Fiat24 is already part of your finances, treat the maintenance notice as a reason to verify access and avoid making it your only route to cash or payments. For prospective users, there is no safe shortcut around the closed application process: wait until Fiat24 confirms it is accepting applications again.

Before connecting a wallet, verify you are using Fiat24’s official service and the intended Arbitrum network. Read the current pricing and legal terms, including fees, eligibility, KYC, custody and withdrawal conditions. Keep only funds you can afford to have unavailable while you confirm how the account works, and test any new payment or withdrawal route with a small amount if the service permits it. Do not buy F24 points on the assumption they are cash-equivalent or will rise in value.
