OpenHW Arduino Pro Mini

OpenHW Arduino Pro Mini is a community-driven project and does not have a public headquarter.

OpenHW Arduino Pro Mini runs on standard microcontroller platforms such as AVR, ESP, and STM32. Private keys are generated and stored locally on the device. Transactions are signed offline and then transferred to a host computer for broadcasting to the network.

OpenHW Arduino Pro Mini was released around June 24, 2019.

OpenHW Arduino Pro Mini is categorized as a hardware wallet and cold wallet. OpenHW Arduino Pro Mini is an open-source, do-it-yourself project that demonstrates how to build a hardware wallet from off-the-shelf components.

OpenHW Arduino Pro Mini has not been involved in any major scandals, hacks, or criminal charges. OpenHW Arduino Pro Mini is open source and non-custodial. As a DIY project the security depends on correct assembly and usage by the builder, and it does not carry the same formal audits as commercial wallets.
