Cryobrick

Man, it’s easy to get black-pilled seeing all this dystopian stuff like VPN bans for age verification and the broader push toward digital IDs, social credit systems, and CBDCs. But seeing people all around the world tinkering to make Bitcoin better freedom money makes me bullish!

@connyb @bitcoinl4b Sandeep wanted to keep the demo streamlined hence he didn't go the ideal but a longer route of using the microSD card to transfer the PSBT and keep the device completely air-gapped. QR signing coming soon. Thanks for your support.

@bitcoinl4b @cryobrick Sandeep plugged a cable into the “air gapped” phone during this illegible demo And, uh, feature phones are getting harder and harder to get hold of, only a few new ones exist in the markets near me But yeah it’s always been an appealing approach

Cryobrick es un proyecto de cold storage Bitcoin airgapped que corre en feature phones basicos, esos celulares de teclado fisico que cuestan pocos dolares, el concepto es simple, el celular queda completamente desconectado de internet y funciona como hardware wallet de bajo costo, el app se llama Compass y permite crear y restaurar carteras Bitcoin sin ninguna conexion de red, costo de hardware cero, plausible deniability porque parece cualquier otra app, your keys your control, proyecto nuevo creado en diciembre de 2025, vale la pena seguirlo en cryobrick.com​​​​​​​​​​​​​​​​ 🧡⚡️

Thanks @studentofbtc for the opportunity, it was an incredible experience participating in this Accelerator. The memories of interacting and working with these amazing group of builders will be cherished.

The 12 weeks flew by. Lots of learning and lots of growing. Let's make it count.

Cryobrick introduces an air-gapped Bitcoin cold storage solution that runs on basic feature phones. The phone remains completely disconnected from the internet and functions as a low-cost hardware wallet. Using the “Compass” app, users can create and restore wallets fully offline. No internet, near-zero cost, and strong plausible deniability.

New open-source project Cryobrick converts cheap KaiOS feature phones into offline Bitcoin hardware wallets. Fully air-gapped and disguised as a Compass app.

@AjayJosh8 @cryptoamanclub think about it this way: what happens if you lose your hardware wallet or it breaks? Your funds are safe as long as you've the mnemonics. You just restore your wallet on a new device.

@cryptoamanclub What if we lost that phone or its broken ???

Hello everyone, thanks for showing your love and support for CryoBrick. We really appreciate it. Order CryoBrick 👇 cryobrick.com Our GitHub 👇 github.com/cryobrick

@realkdc1 @BitcoinArchive @RunwithBitcoin We're trying to get it done faster. Thanks for the support.

@BitcoinArchive @RunwithBitcoin Bitcoin keeps getting better and adoption keeps growing 🟠 x.com/bitcoinintelxy…

Your old Nokia 3310 can now become a Bitcoin wallet. This open source wallet, Cryobrick, can be hidden on basic cellphones like any normal app, giving you private and offline custody. Play Snake and HODL on same device. - @RunwithBitcoin

@elgabocrypt @BitcoinArchive @RunwithBitcoin Not quick enough. Thanks for the support.

@BitcoinArchive @RunwithBitcoin We went from smartphones to “snake game = cold storage” real quick.

@CryptoJerryNL @BitcoinArchive @RunwithBitcoin We have some more Opsec Features not shown in the video. Stay tuned and thanks for the support.

@BitcoinArchive @RunwithBitcoin Cool concept but the security model depends entirely on the phone never being compromised or seen. Cold storage is only as strong as your opsec

@ImCryptOpus @BitcoinArchive @RunwithBitcoin Thanks for the support.

@BitcoinArchive @RunwithBitcoin Retro tech meets crypto, genius innovation, guys?

@Nftdegenmaxi @BitcoinArchive @RunwithBitcoin Only cockroaches and OG Nokia 3310 survive a fallout.

@BitcoinArchive @RunwithBitcoin My Nokia is for defense purposes

@MacroBombastic @BitcoinArchive @RunwithBitcoin Exactly, thanks for the support.

@BitcoinArchive @RunwithBitcoin Bro you are totally missing out on the simplicity of it all.

@CryptoMemeRaj @BitcoinArchive @RunwithBitcoin We tested it, CryoBrick's battery lasted for a month with minimal use and 3-4 days with very heavy usage. We're talking 10 to 15 hours of continuous use.

@BitcoinArchive @RunwithBitcoin snake and bitcoin on a nokia. imagine the battery life, my portfolio tracker could never

@aussiExau @BitcoinArchive @RunwithBitcoin OG Nokia 3310 is a collectible, might be worth more than Bitcoin itself.

@BitcoinArchive @RunwithBitcoin Brilliant idea, time to bring my old 3310 back for Snake and some cold-storage HODL vibes.

@JunoCrypto3 @BitcoinArchive @RunwithBitcoin We'll try and implement it. Thanks for the support.

@BitcoinArchive @RunwithBitcoin Snake high score doubles as security feature

@trynormie @BitcoinArchive @RunwithBitcoin We think so too, that's why we made it. Thanks for the support.

@BitcoinArchive @RunwithBitcoin snake and hodl is diabolical
