The short answerOneKey Pro is the closest thing to an open-source Ledger: comparable multi-chain coverage, well-built software across desktop, mobile and browser, air-gapped QR signing and a secure element. The company is younger and has already had to patch a researcher-disclosed hardware issue on an earlier model.

What we liked, and what fell short
Liked- Open-source firmware with broad multi-chain support
- Air-gapped QR signing plus fingerprint unlock
- Actively developed software across desktop, mobile and browser
Fell short- Shorter operating history than the established vendors
- An earlier model had a disclosed and patched hardware vulnerability
Why the marks landed where they did
The trade-off most buyers face is coverage versus openness — Ledger for chains, Trezor or BitBox for verifiability. OneKey is a serious attempt to remove it: open firmware, a secure element, and support for Bitcoin, Ethereum, Solana, Cosmos, Tron and a long list beyond.
Product quality
The hardware is well made, with a large touchscreen, fingerprint unlock and both USB and air-gapped QR workflows. The software stack — desktop app, mobile app, browser extension — is unusually complete for a hardware vendor and works reliably, which matters more day to day than specification sheets.
The vendor question
OneKey is younger than the incumbents and an earlier model had a hardware vulnerability disclosed by researchers, which the company patched and acknowledged. Handled properly, but it is a shorter record to judge than Trezor's decade. For a device holding significant value over many years, vendor longevity is part of the security model.
Who should use it
Multi-chain users who want open firmware and are comfortable with a newer vendor. Anyone whose priority is the longest possible track record should choose Trezor or BitBox and accept narrower coverage.
FAQ
Is OneKey open source?+
Yes, its firmware is open, which is its main advantage over Ledger at comparable chain coverage.
Has OneKey had security issues?+
Researchers disclosed a hardware vulnerability in an earlier model, which OneKey patched and acknowledged. The current Pro model has no known issues.
Which chains does OneKey Pro support?+
Bitcoin, Ethereum and EVM chains, Solana, Cosmos, Tron and a wide list of others — coverage approaching Ledger's.
Does OneKey Pro support air-gapped signing?+
Yes, by QR code, alongside USB and NFC options.
