Air-gapped Bitcoin cold storage on feature phones.
Zero cost. Plausible deniability. Your keys, your control.

[Robin Linus @robin_linus]

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.

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.

[Santosh V | Student of Bitcoin @studentofbtc]

India is almost invisible on the global Bitcoin stage.

We export talent but don’t build brands.

This accelerator was an attempt to change that.

Here is what 9 teams built over 12 weeks with 0.1 BTC on the line.....👇

[Cryobrick @cryobrick]

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

[Santosh V | Student of Bitcoin @studentofbtc]

India's first Bitcoin accelerator 🥳

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.

[TFTC @TFTC21]

New open-source project Cryobrick converts cheap KaiOS feature phones into offline Bitcoin hardware wallets.

Fully air-gapped and disguised as a Compass app.

[Cryobrick @cryobrick]

@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.

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

[Cryobrick @cryobrick]

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

[Cryobrick @cryobrick]

@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.

[Cryobrick @cryobrick]

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

[Cryobrick @cryobrick]

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

[Cryobrick @cryobrick]

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