Security and ease of use is at the core of the Hodler. Using the latest advancements in microcontroller security we are able to allow the user to safely store funds offline for the long term on a secure element (micro-SD card) while always still being able to spend funds from an on-chip secure wallet isolated by ARM’s TrustZone, all derived from the same mnemonic encrypted and stored on your micro-SD card and on paper.
All of this is however abstracted away to the user to provide maximum usability with a comprehensive and intuitive mobile application (iOS & Android). The Hodler operates wirelessly using a secure custom developed BLE stack and NFC in a future revision. Power your Hodler with Qi charging (optional) meaning you hang it on your keychain, come home at the end of the day and drop your keys on a charging pad.
Optionally one could opt to store all their existing debit/credit cards on the Hodler allowing for a truly complete digital wallet encompassing fiat and crypto. We have experimented with and planned several features for the Hodler (Example: NFC card emulation, Magnetic strip spoofing etc.). We are a young team with limited resources and it would be of great value to have your feedback on what you would like to see in the wallet of the future!
