Strengths
- No issuance, maintenance or renewal fees
- Spend pesos, dollars or crypto directly with real-time conversion
- Works with Apple Pay and Google Pay and CNV-registered as a PSAV
- No notable sovereignty advantage documented.
Weaknesses
- Effectively Argentina-only (requires an Argentine DNI)
- No cashback and no yield on the card
- Custodial: assets are held by Fiwind
- Custodial: the platform holds your funds and can freeze or lose them.
- Full KYC required: verified identity, zero pseudonymity.
- Subject to regulation (Registered with Argentina's CNV in the Virtual Asset Service Providers Registry (PSAV) under number 75 (6 September 2024). The PSAV regime imposes AML obligations (reporting entity under the UIF) but does not constitute a guarantee on user funds.): reporting to authorities and freezes on order.
Verdict
Weak protection: Fiwind is registered with Argentina's CNV as a PSAV (No.75), but the PSAV regime is an AML registry, not a guarantee on funds. The card is custodial and balances are held by Fiwind, with no deposit-insurance scheme.
Low sovereignty: a fully custodial product with mandatory full KYC and reliance on a centralized exchange; the user has no direct control over the keys.

Hack / funds theft Moderate ✓ resolved
Attackers took control of the fiwind.io and panel.fiwind.io domains through a cloud service and altered their content: the app was suspended for hours, funds untouched according to the company
Fiwind announced it itself, on 31 January 2025 at 17:00 CET, on its own X account and with the same wording on its official Telegram channel: "this morning we suffered an attack on a cloud service, through which attackers were able to access our domains fiwind.io and panel.fiwind.io, on which they modified the visible messages and designs. This attack only affected the front end of the websites, all funds are under control. We are working to return the service to normal." The app was taken offline as security protocols kicked in. The next day, 1 February 2025, Argentine outlet iProUP quoted the CEO: "they did not touch the funds and the service is being restored". What we do NOT know, written down because a missing fact is itself a fact: Fiwind published no post-mortem, never named the cloud provider involved, never said how access was obtained, and has never stated anything about customer data — the CEO's denial covers funds, not data. Nor is there any closure statement: the only reference to restoration is that 1 February quote, in the present progressive. The incident is treated as closed because the event was bounded in time and both domains have operated normally since (both checked on 30 September 2026, responding normally). Scope note: Fiwind is a registered Argentine operator (PSAV no. 75, ALYCI no. 2,231, PSP no. 34,539) and the wallet is custodial, so third parties controlling the front end is a risk the user carries even when balances are left alone.
