FiatFlex is a mobile payment platform for merchants. You can accept crypto payments (USDC, EUROC and SOL on the Solana blockchain) through payment links and QR codes, and contactless card payments via Tap to Pay. You stay in control of when to convert to euros and when to withdraw to your own bank account in the SEPA area, while the regulated processing, settlement and banking are handled by third-party partners.

FiatFlex never takes custody of or holds your funds. Funds are handled by regulated third-party payment and banking partners, and you withdraw euros to your own bank account in the SEPA area. FiatFlex cannot and does not guarantee the safety of funds held by those partners; their own safeguarding and protections apply. On the technology side, data is encrypted in transit using HTTPS and secure API connections, and access to certain features can require KYC/KYB identity checks plus AML and sanctions screening carried out by our partners.

Yes — identity verification may be required before you can access certain services. Depending on your account type this can include KYC for individuals and KYB for businesses, along with AML and sanctions screening. These checks are carried out by regulated third-party providers to help prevent fraud and meet their legal obligations. FiatFlex itself is not the regulated entity performing these checks.

You generate a payment link or QR code, and your customer pays in a supported asset on the Solana blockchain: USDC, EUROC, or SOL. You keep manual control — you decide when to convert the crypto to euros and when to withdraw. Payouts are settled to a bank account in the SEPA area through regulated third-party payment and banking partners. FiatFlex does not guarantee the future value of any crypto-asset.

No — you stay in control. FiatFlex lets you manually decide when to convert crypto to euros and when to withdraw your fiat funds, rather than converting or paying out automatically. This gives you flexibility over timing. Conversion and withdrawal are executed through regulated third-party partners.

For crypto payouts, the fee is 0.9%–1.2% plus a flat $1 SEPA fee. For fiat withdrawals, the fee is 1.5%–1.6%, calculated at the time of withdrawal. Withdrawals are sent to a bank account in the SEPA area. Third-party providers or your own bank may apply their own charges.

Yes. FiatFlex supports contactless Tap to Pay over NFC, so you can accept Visa, Mastercard, and American Express, as well as Apple Pay, Google Pay/Wallet, and Samsung Pay. Card payments are processed by regulated third-party payment partners; FiatFlex does not store full card details. You can then withdraw your fiat balance to a SEPA-area bank account, with a 1.5%–1.6% fee applied at the time of withdrawal.

Data is encrypted in transit using HTTPS and secure API connections, and access to certain services can require KYC/KYB verification along with AML and sanctions screening carried out by regulated third-party providers. To be clear, FiatFlex is a technology platform and does not claim to be a bank or to hold any banking or payment licence — those regulated activities are handled by our third-party partners. We handle your personal information in line with applicable UK data-protection law (UK GDPR). No method of transmission or storage can be guaranteed to be completely secure.

Withdrawals are sent to a bank account in the SEPA area. Standard SEPA transfers are typically delivered by the next business day, and some receiving banks support faster settlement where Instant SEPA is available. Exact timing depends on the receiving bank and the regulated third-party partners that settle the payment, so FiatFlex cannot guarantee a specific arrival time.

Yes. FiatFlex works across your devices through a mobile app for taking payments and managing your account, plus a unified dashboard where you can review transactions, conversions, and withdrawals in one place.

FiatFlex is a live MVP mobile payment solution in active rollout, working with early merchant pilots such as food trucks, events, and independent businesses. We are growing deliberately with these early partners as we expand. We do not publish user, transaction, or rating figures we cannot substantiate.

You can reach us by email at contact@fiatflex.com with questions about payments, conversions, withdrawals, or verification. Support is handled by email; we respond as quickly as we can during the rollout and do not operate a staffed 24/7 phone line.
