We built the first open-source privacy-first crypto POS on Solana And we just won 🏆 for the best USD1 Integration for @radrlabs at the Solana Developers Privacy Hackathon. Meet GhostPay 👻💳

GhostPay is an open-source Merchant Kiosk Terminal Designed specifically to review and confirm payments privately. No public balance tracking. No wallet exposure. No revenue transparency to competitors.

Built using: • Raspberry Pi • 3.5” touchscreen display • Custom 3D printed enclosure • Integrated speaker for confirmations • 3D printed case Affordable. Replicable. Open.

GhostPay was built end-to-end during the hackathon : hardware + software. Open source and Replicable. If you’re building on Solana and care about privacy, let’s collaborate 👻

Huge shoutout to @RadrLabs, @originbuilder, and @PeterAngelovX 🙌 Radr’s stack was insanely smooth to integrate, the privacy layer just worked. Zero friction, clean dev experience. Solana privacy infrastructure is just getting started

@radrlabs @solana_devs Spot the 0G mouse pad

@radrlabs @solana_devs Fancy adding a tap to that? 👀

@radrlabs @solana_devs Crazzy work 🚀🚀🚀

@radrlabs @solana_devs Simple implementations are the ones that hit the hardest

@radrlabs @solana_devs Congratulations. There is no better time to ship than now.

@radrlabs @solana_devs Crazy man🫡 Simple and effective 🔥

@radrlabs @solana_devs nice well done

@radrlabs @solana_devs is this related to ???

@radrlabs @solana_devs Hi, @DsouzaJovian! How can I get one in the Philippines?

@radrlabs @solana_devs This is sick execution — privacy-first POS on Solana is a real wedge. Winning with USD1 integration is a strong signal too. 👏

Congratulations, techies for building this successful device. It helps small businesses and merchants a lot. Hope this device is everywhere in the global market in the next 5 years, and congrats on another important step toward making crypto privacy great again. and try to direct interaction from other sol wallets instead of only ghost pay.

@radrlabs @solana_devs Ecosystem goes up, thx to guys like you. Well done builders

@radrlabs @solana_devs @team556_coin did this almost a year ago. Built a whole POS system, payment gateway, and wallet system for the firarms industry and it can used with any other business.

@radrlabs @solana_devs Enjoy the moment. Forgotten in 30 days

@radrlabs @solana_devs Congratulations on the groundbreaking privacy-focused crypto POS innovation!

@radrlabs @solana_devs Insane! 🤯

@radrlabs @solana_devs great job this is going to be a game changer

@radrlabs @solana_devs @0x_Fenrir

@radrlabs @solana_devs Amazing work 🎉🥂

@radrlabs @solana_devs Nah this is a sick build 🙌🏾wow 🤯

@radrlabs @solana_devs cool stuff ser

@radrlabs @solana_devs How can I get one in swizerland?

@radrlabs @solana_devs I can send you one

@radrlabs @solana_devs Dm me

@radrlabs @solana_devs This is cool 😎

@radrlabs @solana_devs building something that prioritizes privacy is no easy feat, distribution will be the real challenge now. getting people to actually use it at scale is where most projects falter

@radrlabs @solana_devs @TrapDefi @incognitoV1_ @BlockchainBae__ @sub0man

@radrlabs @solana_devs Damn congrats 🥳

@radrlabs @solana_devs Nice👌
