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. :)

Thank you to everyone who has donated to Firefly in the Ethereum Security QF round on @Giveth!
There is still 1 day left to donate before the round closes if you want to support our mission of building an accessible, open source hardware wallet ✨

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.

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 .

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. :)

上周拿到的一个带屏幕的超小开源硬件钱包 @FireflyPocket ，有四个按钮，不含电池，一个 Type-C 接口。
还没发售，软件还没完善，像是个小型开发板。
