Thermos Mini-App: NFT Gift Aggregator on Telegram
Thermos is a Telegram-based mini-application designed to help users collect, manage, and trade NFT gifts, created by swap.coffee team.

Nowadays, we have different apps and marketplaces for buying and selling NFT gifts. Finding the best option for your transaction can be time-consuming. The Thermos Telegram Mini-App, built on the TON blockchain by the swap.coffee team, simplifies this process by collecting NFT gifts from different marketplaces into one app, making it easier to browse, compare, and manage them in a single place. So, basically, it’s an NFT gift aggregator app.
What Is Thermos and How Can It Be Used?
Thermos is a Telegram-based mini-application designed to help users collect, manage, and trade NFT gifts, created by swap.coffee team. Instead of checking different marketplaces one by one, Thermos brings all available options together, saving time and effort. Whether you’re a collector or a seller, this app provides a simple and organized space to handle everything.
You can access Thermos directly from Telegram and use it in English, Russian, Ukrainian, or Chinese. Once inside, you can browse NFT gifts, compare prices, make purchases, and even list your own NFTs for sale.
Key Features and Advantages of Using Thermos for Selling & Buying NFTs
- Gift aggregation: Thermos gathers NFT gifts from various marketplaces, helping you find the best price without switching platforms.
- Multilingual support: The app is available in four languages—English, Russian, Ukrainian, and Chinese.
- No user fees: You won’t pay any fees when buying gifts. Instead, partner marketplaces like Tonnel and Portal handle the fees.
- Cashback rewards: When you buy gifts through Thermos, you receive cashback, making each purchase more rewarding.
- Simple interface: The layout is clean and easy to navigate, even for new users.
- Flexible selling: You can sell NFT gifts, whether you bought them through Thermos or elsewhere. You even get to choose which market to sell on. A small listing fee of 0.1 TON per gift applies.
- Built on TON: Thermos operates on the TON (The Open Network) blockchain, which supports fast and secure transactions and is closely integrated with Telegram services.
Why Use Thermos for Buying NFTs?
Thermos stands out for its convenience and user-focused design. By bringing multiple marketplaces together, it saves you the hassle of searching through each one individually. You get better price visibility, cashback incentives, and a no-fee buying experience, all from a simple interface within Telegram.
Another advantage is its flexibility for sellers. Whether your NFT gifts came from Thermos or somewhere else, you can list them for sale and decide which market to use. This level of control is not always available in similar apps.
Possible Drawbacks
While Thermos is helpful, there are a few things to keep in mind:
- Mobile issues: Some users have reported technical problems when using the app on smartphones—for example, the shopping cart may reset when the page refreshes.
- No TON withdrawals: Currently, the app does not allow you to withdraw TON coins, which may limit your ability to manage your balance.
These are minor issues for many users, but it’s essential to be aware of them if you plan to use the app frequently or on mobile. Anyway, all these issues are expected to be fixed soon.
