The question we’ve been asked most this week: is it safe to buy a Tangem from a reseller?

🎉Yes. Supply chain attacks simply don’t apply to a Tangem card. Here’s why.

1. A Tangem card has no "outside."
The secure chip and NFC antenna are sealed into a single monolithic card. There's no screen, battery, port or internal wiring to tap, and no room or power for an implant: the card only draws power from your phone during the few seconds of a tap. In a seedless setup, private keys are generated inside the chip, never leave it, and every transaction is signed on the chip. The only data that crosses the NFC link is an unsigned transaction going in and a signature coming out, both of which end up public on the blockchain anyway. There is no secret in transit to intercept.

2. That's also why Tangem's authenticity check covers what matters. The Tangem app challenges the chip with a cryptographic test that only a card produced by Tangem, running Tangem's original firmware, can pass. That firmware is written to the chip once at the factory and can't be updated by anyone afterward, so it can't be swapped in transit. The app also tells you if the card was activated before it reached you, so nobody can hand you a wallet with keys they generated in advance. If you ever see that message, reset the card and the chip will create brand-new keys that only you control. Because the check covers the chip, and the chip is the whole wallet, where you bought your Tangem doesn't change your security. That includes cards bought through CryptoBilis.

So it doesn’t matter where you buy your Tangem: our official store, any of our resellers, Amazon, Best Buy, Walmart, or even a stranger in an underpass. If the app says the card is genuine, it’s yours and only yours.

We greatly appreciate our resellers' efforts to promote Tangem's mass adoption! They are in 200+ countries across every continent.

Simply Tangem. 🫡

Nice to see that Andrew Rogozov is bullish on memes 👀

& Snoop is promoting a new telegram game 🎮

Timing⏰, slowly then suddenly. I believe the best route to a true TON szn is $100m+ daily dex vol on memes, with that explosive momentum spilling into gifts, stickers, DeFi, usernames and gaming.

💎 Anatoly Makosov shared a closer look at the technology behind Gram Wallet on his 𝕏. We’ve included the details below for easy reading, or you can read the original thread here.

Behind the simple feature set of Telegram’s first Gram Wallet release is a range of technical innovations and close attention to UX:

1. All operations happen onchain through smart contracts.

2. You can send Gram to someone who has never opened their wallet or even updated Telegram.

3. Cloud backup makes the same wallet available across all your devices without importing it manually on each one. The seed phrase is split into three parts, stored in separate data centers on three continents.

4. You can disable cloud backup, rotate your seed phrase while keeping the same wallet address, and later import the wallet into another app, such as the standalone Gram Wallet app.

5. Connecting to a dapp through TON Connect makes the connection available across all your devices. There is no need to reconnect on each device.

6. Five free transfers per day, powered by Gasless & Sponsored Transactions. Further transfers cost next to nothing thanks to this year’s network fee reductions.

7. A network-wide validator vote can upgrade the Telegram wallet’s smart contract to add new functionality. The upgrade applies to all users at once, without requiring a migration. Telegram itself cannot bypass the blockchain’s rules to force wallet upgrades.

This UX combines existing TON capabilities with new developments. It builds on TON’s original architecture, where every account is a custom smart contract that can implement arbitrary logic, alongside the previously released Gasless Tx, Sub-Second, and Sub-Cent updates.

New components include Telegram’s own TON Connect implementation, the tg-wallet-v1 smart contract with key rotation support, a dedicated wallet proxy contract, and other technical innovations.

💜 We’re happy to have contributed to building it! Enjoy the new wallet in Telegram and let us know what you think.
