3/ @100xDevs @kirat_tw First time touching Solana. ~5 days. Shipped: – Offline USDC payments (durable nonce) – On-device intent parsing (local Llama) – Private transfers via MagicBlock – Mobile Wallet Adapter, native Android APK

We built Kumo for Solana Frontier 2026. an offline-first USDC payments app that keeps working when the signal drops. Offline. Private. Built for real-world payments. And we didn’t stop at the main track. We also built for three sidetracks. 🧵

@beeman_nl @dev3pack Thank you, keep pushing with Kumo.

@KumoApp_ @dev3pack Congratulations with winning this price! Loved seeing the offchain transactions and local-first approach! Very innovative! 👏 Hope you keep on building! 💪

Proud to share that Kumo placed 2nd in the Solana Mobile track 🏆 On top of that, we were also selected for the accelerator program an incredible opportunity to keep building and pushing the project further. Excited for what’s next.

Just submitted Kumo to the Dev3pack Global Hackathon! @dev3pack Kumo lets Solana Mobile users create, sign, queue, and settle USDC payments even when connectivity disappears. Check it out 👇 hack.dev3pack.xyz/projects/jx743…
