Forwarded from Tangem
The question weโve been asked most this week: is it safe to buy a Tangem from a reseller?
๐ Yes. Supply chain attacks simply donโt apply to a Tangem card. Hereโs 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 doesnโt 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, itโs yours and only yours.
We greatly appreciate our resellers' efforts to promote Tangem's mass adoption! They are in 200+ countries across every continent.

The gap between โwhat ifโฆ?โ and โlook, it works!โ has never been smaller, and that changed how we build features in Telegram.
Message @designers to submit your concepts.
โ Working, ready-to-implement code
complemented by
โ A demo video of your feature in action
โ Static mockups
โ Demo videos with no code behind them
โ Text-only concepts
No coding background? Curiosity, attention to detail and a good prompt will take you far.
The future of design isnโt drawn โ itโs built.
(An example of what is possible by our iOS designer โ this is a ready to use implementation not a motion video.)
Media is too big

We didn't go multichain to leave. We went to bring people here.
Everyone dumps on TON memes. Weโre handing them out, adding 1,000 prizes to the Keeper Multichain Mystery Raffle.
We went onchain shopping and bought some $UTYA, $DOGS, $REDO, $LAMBO, $NOT and $GROYP from the open market.
Distribution is king, Keeper remains the place to trade jettons, memecoins and all ecosystem assets.
Swap $100 crosschain in Keeper and get one ticket.

@rogozov @keeper_wallet Thank you @rogozov๐, can we expect @durov to soon give a nod to say GRAM is good for buying memes whilst he continues to build for 1b users?

Nice to see that Andrew Rogozov is bullish on memes ๐
& Snoop is promoting a new telegram game๐ฎ
Timingโฐ , 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.
