About the project

A marketplace
inside Telegram.

Context

GOI Market is a marketplace for digital gifts — NFT stickers — inside Telegram. People buy, sell and trade them for TON without leaving the messenger and without landing on any outside site. Not one browser tab in the whole purchase.

Development stages

From concept
to launch.

Concept

We settled the format: a Telegram Mini App paying in TON. There was one goal — make the path from "saw a gift" to "it is mine" as short as it goes.

Architecture

We took the app apart into separate pieces: shop, cart, profile, wallet connection. One task on a screen, never five at once.

Design system

We built the dark theme: a black ground, cards one tone lighter with a hairline outline, one accent — the TON blue. It settles into night-mode Telegram as if it belonged there, rather than arguing with it.

Logo

We drew the GOI logo: geometric typography in a pixel style. It is about the digital nature of the product, and it stays sharp at any size.

The shop

We built the grid of lots with prices in TON and three ways to narrow it down: by collection, by order and by price range. Each slides up as a sheet from the bottom — right under the thumb.

Wallet and payment

We connected TonConnect: a wallet links in a couple of seconds. After that, buying is one tap, with no screens in between.

Cart and checkout

We made a cart with nothing spare in it: the total and a pay button. Between the shop and the cart it is a gesture or a tap, whichever you prefer.

Testing and launch

We put it through real phones, fitted it to every Telegram screen size and shipped it through the Telegram Bot API.

Logo

A logo in digital
form.

The logo is built on geometric typography. The pixel style speaks to the digital nature of the product, and the plainness of the shape holds it legible at any size: from an icon in a chat list to a banner.

Interface

One screen,
one task.

The buyer's path

Eight screens in a row — and that is the whole path: the listings, three ways to narrow them down, a lot card, the cart, your own listed gifts and the profile with the wallet. Not one step outside.
