Colibri is a free and open source DIY project, with the goal to enable everyone with $5 and access to a laptop and Internet™ to create their own secure crypto hardware wallet, using off-the-shelf ESP32 hardware development boards.
Head over to colibri.diy to find build instructions and more information!
a nice side effect from creating my project website though is that it includes a setup wizard, so you'll finally be able to actually do something with your Colibri wallet 😅 plus I've wrapped up the code I've used into a TS/React SDK that can be reused for the MyEtherWallet fork! just need some more time and energy, but soon ™️
Any of these low-cost ESP32 development boards (ranging from ~$3 to ~$15 on Aliexpress) can be turned into a fully functional and secure crypto hardware wallet with colibri.diy - ofc fully free and open source
The project is still in the pre-release stage, but if you like tinkering with Arduino & hardware, check out the github repository for the firmware and build instructions.
While there haven't been too many major changes, I've added base address derivation for Solana and Polkadot/Substrate chains, and added DASH, DGB and ZEC support in the "Bitcoin-like" category.
In the background, I've also
prepared a Nextra.js skeleton for the companion webapp
planned the site's structure, functionality and content
sketched out the complete GUI design for the display integration in v0.1.x
The next release will be focused around the companion webapp, so that you can actually set up your wallet without having to resort to BLE debugging tools to do so.
After that's out of the way, I'll be integrating everything into a MyEtherWallet fork, so it finally starts to feel like a real hardware wallet :)
DIY crypto hardware wallet, based on cheap ESP32 board - build yours easily with Arduino IDE, starting at $4 in parts! - GitHub - xtools-at/colibri: DIY crypto hardware wallet, based on cheap ESP3...
I'm Martin and have been working on a free and open-source, fully DIY crypto hardware wallet for a couple of months now. I' ve just published the first functional preview of the firmware, which can be built by anyone easily using Arduino IDE, and flashed to a variety of $5-off-the-shelve ESP32 boards from Aliexpress.
The first release will allow for storing up to 30 encrypted seed phrases, and Ethereum signing via Bluetooth Low Energy. Under the hood, it's powered by the cryptographic libraries written and used by Trezor.io.
Support for more interfaces and chains can be added fairly easily due to a modular structure, and there is a whole roadmap planned to extend functionality (starting with support for displays).
