🧡 A special delivery from Tangem has arrived in Madrid!
Being a Tangem Ambassador is about more than representing a brand. It’s about being part of a global community promoting blockchain education, financial freedom and self-custody.
Because true digital sovereignty begins with knowledge and the ability to take control of your own assets.
A big thank you to the @Tangem team for this special gift and for making us part of this journey.
From @Madrid to the world! 🇪🇸🌍
🔐 NOT YOUR KEYS, NOT YOUR CRYPTO.

YOUR CRYPTO. YOUR KEYS. YOUR DECISION.
Imagine waking up tomorrow and discovering that:
• Your exchange has suspended withdrawals.
• A platform you trusted has been hacked.
• A bridge has paused operations.
• Your account is under review.
• Your funds are temporarily inaccessible.
Now ask yourself one question:
Do you actually own your crypto, or do you simply have a balance on someone else’s platform?
This is one of the most important lessons in the crypto industry.
When your assets remain on a centralized exchange, you depend on its infrastructure, policies, security and ability to process withdrawals.
Self-custody changes that relationship.
With a hardware wallet like @Tangem, you hold your private keys and retain control over how and when you access your assets.
No exchange withdrawal approval.
No dependency on a centralized platform to authorize access to your wallet.
But let’s be clear: self-custody doesn’t eliminate every risk. You still need to protect your keys, verify transactions and understand the networks you use.
Because financial sovereignty isn’t just about owning Bitcoin.
It’s about having the freedom and responsibility to control it.
Don’t wait for the next crisis to understand the value of self-custody.
Not your keys, not your crypto.
🔐 Take control with Tangem.

🚨LEDGER SPY IMPLANT FOUND IN EUROPE TOO!
@0xJohannes_ says a Ledger he bought in store from an official European reseller had extra cables inside. A clean device does not.
He says it looks like an older version of the spy implant.
@MagicalTux said the antenna is labeled as a Eurasian version, so more could be out there.
Reports now include Asia, South America, and Europe.
Always buy from the maker.

What if a major risk to your crypto wallet came from something you couldn’t see?
Recent security reports remind us that hardware wallet architecture matters.
🔐 It’s not just how we protect our keys — but how we design the systems protecting them.

🚨 I LOST $23,050 IN CRYPTO THROUGH @SafePal TODAY.
3 out of my 4 SafePal wallets were drained. All 4 were created separately on the same iPhone, with different seed phrases.
My seed phrases were written in a physical notebook. I never knowingly approved any transactions.
I never clicked on any suspicious links, never downloaded any fake apps, and no one else has access to my iPhone.
Yet 3 wallets were emptied while the 4th remained untouched.
@safepal_support , HOW DID THIS HAPPEN?
I need a proper investigation and a clear explanation. How can 3 separately created wallets be compromised under these circumstances?
$23,050 lost. No answers yet.
I'm sharing this publicly because I want @SafePal to take this seriously and address what happened. 🧵

闲置(电池坏掉)的ledger冷钱包已拆，前两张图是我的，第三张图是网友发的有间谍部件的。
看起来我这款应该没有被篡改。
从技术角度看，这个冷钱包去掉金属外罩，直接用手就能抠开，如果有人想要篡改，是非常容易的，连工具都不需要，想开就开。
第四张图是锂电池的背面，用的普通双面胶，轻轻一抠就掉。
整个钱包电路板看起来不复杂，所以不法分子很容易就能破解，并且想怎么修改都是可以的。
想象一下，你即便是在官网买的，海关查包裹，放进去一个间谍部件，我是说如果，没有诋毁任何一个国家海关的意思。
即便没有被安装间谍软件，这么一个简单的东西，你敢把钱放里面？有的人甚至大几百万U放里面，想一想都背后发凉，头顶冒汗。

¿Por qué Tangem no necesita seed phrase?
#TangemWallet no elimina la clave privada
En modo seedless, se genera y protege en el chip
No necesitas gestionar 12/24 palabras
Seedless≠sin clave privada
Otro modelo de autocustodia
¿Qué pasa dentro del chip? 👀

🇪🇺 NEW: The ECB launches Pontes, enabling digital euro payments for tokenized wholesale transactions between banks.

🇪🇺BREAKING: ECB launches “Digital Euro” for banks as Pontes begins tokenized finance pilot.
President of the European Central Bank, Christine Lagarde announces The ECB is launching Pontes today, a platform that will connect private blockchain networks with the TARGET system, allowing banks to settle tokenized assets directly in central bank money.
“It's digital euro made available for banks,” the ECB says, allowing institutions to transact using tokenized assets and DLT “faster, without friction," she adds.
Pontes is the first step toward the ECB’s broader Appia ecosystem for tokenized financial markets, while consumer-facing digital euro testing is planned for mid-2027.
