Inspiration

zrk.ua is one of most popular handmade platforms in Ukraine where anyone can create handmade store and sell unique handmade stuff. We develop this platform 7 years ago using Laravel and support it all this years. Main issue for us all this time was direct payments between craft-mans and customers - how user can pay directly to craft-man and avoid huge fees.

What it does

For this hackathon I added new payment option for our stores and solve our pain: now any craft-mans can set NEAR wallet address to enable direct crypto-currency payments. When someone create new order for this store and chose NEAR Wallet as payment option, we calculate payment amount and use NEAR blockchain for this payment.

To control payments and update database I create separate open-source solution with smart-contract (used for payments and temporary data storage of new transactions) and server-side script that connect to this smart-contract and synchronise new orders list with server database.

How we built it

I updated zrk.ua platform: add new payments method, update cart and orders processing, add payment status in database and user interface. Main issue was - how to make sure that payment was success, user pay correct amount and update our database based on blockchain transaction.
To solve this issues I created separate open-source project that process our payments and update database. I configure server-side script that connect to smart-contract and regularly check if we have new payments (used smart-contract storage). When new payment detected - server update database records and cleanup smart-contract storage.

Now store owner (craft-man) can see that payment was made for new orders, can accept it and clarify details with customer.

For testing use our demo website: demo.zrk.ua. "Try it out" links section include the link to store with enabled NEAR Wallet payment method.
