One surface for marketplace, wallet, and loyalty
Qart is an open-source bitcoin commerce app for people, shops, and local networks. It brings inventory, payment, identity, and receipts into one system instead of splitting them across disconnected tools.
Inventory that travels with you
Keep track of what you own, list what you want to sell, and move between personal and merchant contexts without switching products.
Payments that settle directly
Qart is built around bitcoin-native checkout, low-fee transfers, and receipts that stay linked to the transaction.
Identity that stays yours
Handles, contacts, follows, and order history are part of the product, not something rented from a third-party platform.
What Qart combines
Most commerce stacks fragment the experience into storefronts, wallets, loyalty software, reporting tools, and API gateways. Qart keeps those layers in one product so the flows stay coherent.
Marketplace
List items, browse other sellers, check out, and manage orders.
Wallet
Manage balances, addresses, transactions, and direct payments.
Merchant tooling
Run POS, loyalty, prepaid cards, and reports for real shops.
Programmable commerce
Use the 402 paygate, checkout APIs, and keypair auth for new flows.
In one account
Items and listings
Personal inventory and active market listings live side by side.
Wallet and transfers
Keep balances, request payments, and move funds directly.
Merchant operations
Switch into POS, orders, and reporting when you are running a shop.
Identity and trust
Handles, follows, reviews, and receipts reinforce the network over time.
Principles
Open source
The code is inspectable, forkable, and deployable on your own terms.
Data ownership
Your contacts, items, and transaction history should not be trapped in someone else's silo.
Peer-to-peer default
Payment, messaging, and exchange should work directly between participants whenever possible.
Programmable commerce
Receipts, loyalty, and APIs should be first-class product features, not bolt-ons.
