Coinkite

Physical key storage and transaction approval define Coinkite, a Bitcoin hardware manufacturer behind OpenDime bearer devices and Satscard NFC products. Rather than offering an undifferentiated crypto service, Coinkite organizes its work around Coldcard wallet devices, OpenDime bearer devices, and Satscard NFC products. Changes in Bitcoin-only security model provide one reporting trigger; developments around air-gapped transaction signing or PSBT workflow support provide others when they alter device security, signing and recovery. This entry stops at the organizational boundary of Coinkite; individual device models, companion wallets and blockchain assets connected with Coinkite require their own tags when examined independently.
