Strong as hardware. Fast as hot wallets.
With the power of the @solanamobile you can turn any USB drive into a key signer
No proprietary hardware.
No vendor lock-in.
Just self-custody built for the next generation of Solana users.
Coming Soon

Introducing Blockchain x Quantum Hackathon in collaboration with @Fidelity (@FCATalyst) and Quantum Ireland.
€15,000 in prizes
23-24 May, @dogpatchlabs
Quantum computers capable of breaking today’s cryptography are getting closer to reality. While major blockchains are preparing to transition to post-quantum algorithms, there’s a critical issue flying under the radar: new cryptography brings new risks and unknowns. Now is the time to embrace crypto agility.
With @DublinTechWeek around the corner, there’s no better moment to get involved.

Stop trusting hardware wallets.
You’re still trusting:
• the manufacturer
• the firmware
• the supply chain
Coldstar doesn’t ask for trust.
Bring your own hardware.
Keep your keys.
Own the entire system.
Real self-custody.

GM!! Wallet holders..
@buildcoldstar lets you turn a simple USB into a real cold wallet.
No expensive hardware.
No hidden systems.
Just open-source security and full control over your keys...

Have you ever thought you could store your crypto offline…
using something as simple as a USB?
instead of relying on a 12-word phrase you could forget or lose
All you need is your windows or Linux or Mac PC
I made a quick walkthrough on how this works with Coldstar 👇

Fun fact: the first ever Bitcoin hardware wallet prototype was literally a USB stick with custom firmware.

The first ColdStar users are born 💫
@buildcoldstar founder @devsyrem turned our Talent Hub attendees’ standard USBs into cold-storage wallets.
No magic involved, just ColdStar’s CLI-first program that converts any USB drive into a @solana-native cold wallet.
One to watch out for @colosseum 👀

Forgot to mention that there is a @buildcoldstar wallet in Málaga somewhere with 10 SOL
I’d say it’s somewhere here 👀
