[Project] OmniStack — A permissionless payment & escrow protocol on ICP, built in public. Mainnet deploy incoming.
Hey r/dfinity, I've been working on OmniStack for a few months and we're close to launching on mainnet. Want to share what we've built, why we chose ICP, and ask for your support.
What is OmniStack?
A decentralized commerce layer with:
Payments canister — creates payment requests (like Stripe Checkout, but on-chain). Merchants set up a request, buyers approve it using ICRC-2.
Settlement canister — batches and sends merchant payouts in ckUSDC/ICP on a schedule.
Escrow canister — holds funds for multiple parties with dispute resolution, enabling "Pay on Delivery".
Registry canister — links merchant IDs to payout settings and branding.
OmniWallet — a mobile wallet (iOS/Android/PWA) for regular users. Self-custodial, Internet Identity login.
Tech stack: Rust canisters, ICRC-1/2 compliance, React 19 frontend, Capacitor 8 for mobile.
Why Internet Computer?
Most "DeFi checkout" solutions involve EVM contracts, central servers, and AWS frontends. That's not decentralized.
With ICP:
The checkout UI runs directly from a canister
Payment logic is on-chain
Settlement is on-chain
Internet Identity = no seed phrase issues for regular users
ckUSDC gives us a stablecoin without bridging risks
Everything is on-chain — that's the goal.
Current status:
✅ All canisters tested locally
✅ OmniWallet complete (dashboard, transfers, payments, activity)
✅ PWA ready, Capacitor synced for iOS + Android
🔄 Mainnet launch in progress (Phase 2 this week)
📱 App Store + Google Play submissions after mainnet confirms
I'm building this alone, no funding. If you believe in this project and want to help:

Small contributions help cover canister costs during launch.
Happy to answer questions about canister design, ICRC-2 flow, or Capacitor + ICP setup. AMA.
