SecuX V20
SecuX Technology Inc.
Data verified on unchanged since the sources
Worth it if you want an affordable multi-asset hardware wallet (€92) with a CC EAL5+ certified secure element and a 2.8" colour touchscreen for 5,000+ assets.
Avoid it if you demand maximum isolation: it is not air-gapped (it uses Bluetooth) and the firmware is closed-source, not verifiable in code.
The SecuX V20 is the flagship hardware wallet from Taiwan's SecuX, with a large 2.8" colour touchscreen and an aluminium body. It protects private keys with an Infineon Solid Flash secure element certified to CC EAL5+ and keeps them offline, requiring manual on-screen approval of transactions. It connects over USB-C or Bluetooth 5 BLE to desktop and mobile apps: the Bluetooth convenience, however, means the device is NOT air-gapped. It is multi-asset (Bitcoin, Ethereum, ERC-20, XRP, Litecoin and over 5,000 claimed assets). The official list price is USD 99 (~€92). The firmware is not published as open-source: its security model must be taken on trust.

Plans & pricing
Strengths
- Infineon CC EAL5+ secure element; large 2.8" colour touchscreen; broad multi-asset support (5,000+ claimed); dual USB-C and Bluetooth connectivity with desktop and mobile apps.
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- No KYC: usable without identity verification.
Weaknesses
- Not air-gapped: the Bluetooth connection widens the attack surface compared with QR/microSD-only wallets; closed-source firmware that cannot be verified in code; no fully offline signing app.
- Closed source: no way to verify what it does with wallet and data.
Verdict
Score 3.8/5, solid profile. In its favour: infineon CC EAL5+ secure element; large 2.8" colour touchscreen; broad multi-asset support (5,000+ claimed); dual USB-C and Bluetooth connectivity with desktop and mobile apps. The trade-off to weigh: not air-gapped: the Bluetooth connection widens the attack surface compared with QR/microSD-only wallets; closed-source firmware that cannot be verified in code; no fully offline signing app.
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.

SecuX app banner modified by hackers: it pointed to clone sites asking for the recovery phrase
The flaw lies in the SecuX app, not in the device: in its official alert of 19 Oct 2026 SecuX confirmed that the banner inside the app had been "maliciously modified by hackers" to show links to websites impersonating SecuX. Those sites claimed the wallet had "critical security vulnerabilities" or needed "immediate wallet verification" or a "security update", and asked users to enter their 12- or 24-word recovery phrase. The case surfaced on the evening of 16 Oct, when David Schwartz (former Ripple CTO) reported a phishing notification received from the Android app; the same day SecuX put the app into "emergency maintenance", declaring it operational again shortly after, while on 17 Oct several users still reported being unable to log in. SecuX has not explained how the attackers gained access to the banner, nor said how many users were reached or whether anyone lost funds: as of 21 Oct no loss has been quantified. The company says its investigation is ongoing. No reimbursement has been announced.

FAQ
How much does the SecuX V20 cost?
The official list price is USD 99, about €92 at the August 2026 exchange rate. At third-party retailers (Walmart, Best Buy, Newegg) the price can rise to around USD 114.
Is the SecuX V20 air-gapped?
No. It connects to a computer over USB-C and to a phone over Bluetooth 5 BLE. Keys stay in the secure element and transactions must be approved by hand on the touchscreen, but the Bluetooth radio means the device does not run in a fully air-gapped mode.
Which secure element does it use and how many coins does it support?
It uses an Infineon Solid Flash secure element certified to CC EAL5+. SecuX claims support for over 5,000 assets, including Bitcoin, Ethereum, XRP, Litecoin, Dogecoin, BNB/BSC and ERC-20 tokens.
