Firefly firefly.eth was originally created for a Blockgeeks Lab Blockchain Hackathon, where it placed second, and was later revived after a period of limited development activity. The project is backed by ENS DAO, which has supported its continued development. Firefly firefly.eth publishes all hardware schematics, PCB designs, firmware, and tooling as public repositories through its GitHub organization.
Firefly firefly.eth's current hardware offering, the Firefly Pixie DevKit, is built around an ESP32-C3 32-bit RISC-V microcontroller and features USB-C, Bluetooth LE, a display, and programmable buttons. The device can sign Ethereum transactions, messages, and attestations, and also supports running games and custom firmware. The DevKit is aimed at developers, security researchers, and experimenters rather than general consumers, and the project notes it is not yet ready for retail distribution. Current hardware does not include a secure boot or enclave, though future devices plan to offer a secure-boot option alongside research into more transparent alternatives.
