A plan byimKey Pro
The imKey Pro is the hardware wallet tied to the imToken ecosystem, one of the most widely used mobile wallets in Asia. It costs $109.99 (~€100). Its strength is the Infineon SLE 78CLUFX5000PH secure element, Common Criteria EAL6+ certified and EMVCo-compliant (the same standard as payment cards), with offline private-key generation and storage. It is designed to work paired with the imToken app (and is Rabby-compatible), which handles signing and transfers; the connection goes through the companion app and is not air-gapped. It claims support for 12 main chains and over 5,000 tokens. ⚠️ The firmware does not appear to be published as open-source and some details (connection type, corporate data) are not confirmed on the official site: the card is therefore flagged as partial.
