The official site was unreachable at verification time (DNS/timeout): the price (~€199) comes from third-party retail sources, not the official store.
For this reason this service does not appear in our rankings, comparator or comparison pages: it will once its terms can be verified against a dated official document.
OPOLO Cosmos
OPOLO
The OPOLO Cosmos is the hardware wallet from Luxembourg's OPOLO, built around an NXP secure element certified to CC EAL6+: one of the very few devices to claim that certification. It has a large touchscreen, a randomized on-screen keyboard for entering passwords and passphrases (up to 120 characters) directly on the device — to neutralise keyloggers — and a desktop companion app. It connects over USB and is NOT air-gapped. It is multi-asset, with over 1,500 supported coins and tokens. The official server was not reliably reachable at the time of verification, so the price (~€199, from retail/review sources) is given as an estimate and the entry is flagged as partial data. Firmware is not open-source.

In its favour: nXP CC EAL6+ secure element, among the highest claimed on the market; randomized on-device keyboard against keyloggers, passphrase up to 120 characters; broad multi-asset support (1,500+); dedicated desktop app. The trade-off to weigh: not air-gapped: USB connection, with no QR or microSD option; closed-source firmware; unstable availability and pricing — at the time of verification the official site was not reliably reachable and the price (~€199) is an estimate from retail sources (partial data).
On the Sovereignty lens the score is 3.5/5 (solid): the strength is fund control (5.0/5), while trustless / auditability (0.0/5) is the weak link.

FAQ
How much does the OPOLO Cosmos cost?
The indicative price is about €199, reported by reviews and retail sources. At the time of verification the official OPOLO server was not reliably reachable, so we treat the figure as an estimate and flag the entry as partial data.
What makes the OPOLO Cosmos special?
The NXP secure element with CC EAL6+ certification, among the highest claimed on a consumer hardware wallet, and the randomized on-screen keyboard: passwords and passphrases (up to 120 characters) are entered on the device, not on the computer, reducing keylogger risk.
Is the OPOLO Cosmos air-gapped?
No. It connects to a computer over USB through the dedicated desktop app, with no QR or microSD option. Keys stay in the secure element, but there is no fully offline signing mode.
