🚀 Proud to join the @Tangem Ambassador Program!

As a blockchain educator, I’m excited to help more people understand self-custody and secure crypto ownership.

Thank you, @Tangem, for this opportunity! 🔐

My Tangem app makes it all simple.

I hold my crypto and pay with USDC via #TangemPay all in one place.

No jumping between exchanges, external wallets or apps. Just fast, simple payments when needed.

Today, I paid at McDonald’s with Tangem Pay⚡️

We have some difficult news to share. Unfortunately, one of our shipping providers has experienced a data breach that exposed sensitive order data. This affects new customers in the US, UK, Sweden, Colombia, Brazil, Italy, and Portugal who received an order within the 90 days prior to August 8th, 2026.

The data exposed:

- Full names
- Shipping addresses
- Phone numbers
- Email addresses

The incident affects 11,742 customers with full exposure (name, email, phone number, shipping address) and 1,947 customers with partial exposure (name, city, email). The breach is limited due to Trezor’s strict 90-day data storage policy (we were also able to negotiate the same terms with fulfillment partners, who follow the same policy).

All affected customers have been contacted separately by email.

Our systems and devices remain secure, but affected customers could experience an increase in phishing attempts.

NEVER enter your wallet backup on a website or share it with anyone, and only check for updates on official Trezor channels.

We are deeply sorry to the community and those affected.

We are investigating this situation and will post updates on our blog:

Big week for Solana. Fast UX, growing ecosystem, and real-world adoption keep pushing the space forward. Curious to see what’s next. 🚀

@cz_binance Securing a seed phrase is one of the biggest barriers to self-custody. That’s why solutions like @Tangem are so interesting—they keep users in control of their private keys while simplifying the experience. Do you think seedless wallets will become the new standard?

[Instituto Blockchain @InstitutoBlock]

“Not your keys, not your coins.” Exactly why I use @Tangem. I keep full control of my private keys inside a certified Secure Element, with a simple and secure self-custody experience.

As a blockchain educator, I’ve learned that security is only effective if people can actually use it. That’s why I value @Tangem: strong security architecture, simple user experience, and true self-custody without unnecessary complexity.

Last week’s Coldcard exploit ($85M+ drained so far) is still reverberating. @CoinDesk asked hardware wallet makers to weigh in — story by @sndr_krisztian.

Our CTO @lazutkinandrew: open-source firmware alone doesn’t guarantee security. “Security comes from strong architecture, thorough testing and independent verification.”

@MDXreal @Vishhnooooo @Ledger Respectfully, I disagree. @Tangem combines strong security with simplicity. Private keys stay inside the secure chip, and the NFC experience makes self-custody easier for more people.

[Instituto Blockchain @InstitutoBlock]

@MDXreal @Ledger I value @Tangem because it makes self-custody simple without compromising security. Private keys stay inside the card, NFC is intuitive, and backup cards help users stay in control of their assets. Simplicity is key to broader self-custody adoption.

@0_3_BTC Tangem: easy to use and secure.
Ledger: great, but requires a bit more technical knowledge.
Trezor: also excellent, with a slightly steeper learning curve.

The founder of QuadrigaCX died. Then investigators discovered the exchange’s wallets had been empty 8 months before his death.
One lesson still stands:

“Not your keys. Not your coins.”
