What it means for you
OneKey is the open-source-purist alternative to Ledger and Trezor with comparable hardware quality at slightly lower prices. For HNW users who specifically want auditable firmware end-to-end across a broad set of assets, OneKey is a credible choice. Smaller user base means fewer community-backed integrations than Ledger.
