Introduction

Near Postcards dApp is an example of a fully decentralized Near protocol service that stores all data directly on the blockchain itself, including design templates and web interface.

Inspiration

We have long wanted to combine in one project small features that we liked while working on other projects.

Finally, we managed to create an example of dApp for programmers of the Near ecosystem, how you can integrate your application into the official web wallet, and provide users with access from it in 2 clicks.

What it does

The service provides the ability to send NFT images simulating paper postcards with a postage stamp with the flag of the country of origin, postal seals and stamps.

The sender can write a short text (200 characters) which will be displayed on the NFT postcard.

Challenges we ran into

At first it was a bit unusual to use web4 instead of vps server.

It was necessary to create a contract of a small size and fit in it both graphic postcard templates and a web interface.

The result was good, the contract file size is 430kb

What's next for Near Postcards

The project was created as an example to show various kinds of small solutions for applications.

But if the service is used, then over time we will add more and more country flags to it, as well as new features.
