Welcome to Firefly, the open-source, open-hardware device for Ethereum. Update your firmware at firefly.box/flash ✨

Earth
We’ve put out a quick article for Firefly but also wanted to extend a huge “Thank You” to @thedaofund, @quantstamp and @wintermute_t for their role in helping Firefly thrive (via @GivETH). We need more of these players with strong open-source alignment to keep the future bright and free (as in speech) for all. :) blog.ricmoo.com/firefly-upda…

some great @FireflyPocket hacking
I’ve just spoken to @TMIYChao from the Ethereum Foundation and he liked what I’ve done, I’ve received some useful feedback and now I know what I need to work on.

Amazing times at @ETHPrague, seeing old friends and making new ones! <3 A few cool Firefly hacks coming out of the woodworks too as we handed out 250 free devices to hackers and attendees, with over 1,100 in the wild now! If you hacked on Firefly, share it replying to this tweet or tagging @FireflyPocket. :) We’re also in the Giveth round if you want to help put more free devices out into the world, every dollar is amplified by its quadratic funding. :) qf.giveth.io/project/firefly…

Hardware wallet security should be open, readable, and affordable. @FireflyPocket is building an open-source Ethereum hardware wallet with public hardware schematics, open firmware, and human-readable transaction verification on-device.

Hey @ricmoo nice to meet you IRL. My friend made two-player DOOM on two Firefly devices. Here is Proof-of-Other-Player aka PoOP 💩 You see the other player in green, right before he got shot in the back. {Oh, it's Ethereum (it always was)}

It's time to scale Firefly production so we can get more devices into the hands of developers ✨ We just published an RFP with a $5k USDC reward for an injection molded case for the Firefly Pixie. Firefly Forum 👉 forum.firefly.app/t/rfp-inje…

Check out @FireflyPocket: made for @ethereum hardware (devkit), open-source for developer customization. In use here as a PoC wallet + mini gaming device, built to be secure, affordable, and hackable. Learn more → firefly.app
I spent some time over the weekend vibecoding (to distract myself from the news) and updated the @FireflyPocket firmware with some games and a PoC Ethereum wallet. Thanks @ricmoo for the giveaway at @EFDevcon Bangkok. Such a cute/cool hardware . github.com/shayanb/pixie-fir…

I’m at @ETHGlobal Cannes, with a couple Firefly DevKit devices to hand out. Drop by and visit me if you’d like one to play with, hack on or just satiate your FOMO. Or just chat about Firefly or Ethers.js. :)
Curious what goes into assembling a Firefly Pixie DevKit? We've got a couple hundred more ready for ETHCC, come find us! Hack the Planet! :)
