Chronology
Lifecycle timeline
Tangem card-shaped wallet launched
Product: Tangem Wallet Card
Tangem states that its card-shaped Tangem Wallet was introduced in late 2021.
Tangem Ring opened for public preorders
Product: Tangem Ring
Tangem opened public preorders for the Tangem Ring on July 17, 2024 after unveiling the wearable hardware wallet at the 2023 Cardano Summit.
Tangem released iOS 5.19.1 and Android 5.19.2 to fix mobile-app log exposure
Product: Tangem App
Tangem's official security changelog records a December 27, 2024 security/bugfix release that fixed the mobile-app logging bug for the same seed-phrase plus in-app-support condition.
Tangem App logging bug could include private-key material in diagnostic logs
Product: Tangem App
Tangem disclosed that when a wallet was activated with a generated or imported seed phrase, a bug in the mobile app's NFC logging mechanism could write the private key into app logs. Potential exposure required the user to also contact Tangem support through the app within seven days, allowing those logs to be included with the support interaction.
Tangem Mobile Wallet launched
Product: Tangem Mobile Wallet
Tangem introduced the Mobile Wallet as a free self-custody wallet available directly inside the Tangem app, with encrypted wallet keys stored in the smartphone security environment rather than a Tangem card or ring.
