Verdict up front: SecuX builds the most screen for the money in hardware wallets — the V20’s 2.8-inch color touchscreen in an aluminum shell at $139 makes a Ledger Nano feel like a keyfob. The hardware is genuinely pleasant, the EAL5+ Infineon secure element is real, and the multichain support is broad. The reason it sits at 3/10 on our verifiability board — the lowest tier we track — is simple: the firmware is closed. Completely. What follows is the fair version of both halves.
The lineup at a glance
| V20 — $139 | W20 — $119 | |
|---|---|---|
| Body | Aluminum, premium feel | Durable plastic |
| Screen | 2.8″ color touchscreen (360×240) — the class leader at these prices | |
| Secure element | Infineon SLE Solid Flash, CC EAL5+ | |
| Connectivity | USB-C + Bluetooth 5 | Micro-USB + Bluetooth 5 |
| Battery | 600mAh, roughly 10 days of typical use | |
| Coins | 10,000+ tokens across 300+ chains | |
| Our verifiability score | 3 / 10 — methodology | |
What SecuX gets right
Address verification is the daily job of a hardware wallet, and SecuX’s screen makes it effortless — full addresses, readable fonts, touch navigation that doesn’t fight you. The Taiwanese firm has shipped since 2018 without a published breach, keys are generated and held in certified silicon, and the V20’s aluminum build outclasses plastic rivals at twice the price. As a piece of consumer electronics, it’s the most comfortable mid-tier device we’ve handled.
Why it scores 3/10 anyway
Our methodology pays for proof, and SecuX offers certification instead: closed firmware (0/3), no reproducible builds (0/2), and the EAL5+ evaluation standing in for public audits. That’s the Ledger bargain without Ledger’s decade of scrutiny — you trust the vendor, full stop. Nothing suggests the trust is misplaced; nothing lets you check, either. At $139, the Keystone 3 Pro costs $10 more and publishes everything including its secure-element firmware — that comparison is the whole review in one sentence.
Who should buy it — and who shouldn’t
- Buy it if: screen comfort drives your choice, you hold across many chains, and vendor certifications satisfy your threat model — the V20 is the nicest closed-source device in its bracket.
- Skip it if: verifiability matters at all to you — $149 buys a fully-open Keystone, $129 a fully-open Safe 5; or you want Bluetooth gone entirely, in which case see the air-gapped section of our table.
