Behind the scenes: Trezor Pulse
Welcome to Trezor Pulse! This month, we’re sharing highlights from the biggest Bitcoin event in Europe, AI-generated team portraits, major Trezor Suite updates, How to spot a fake Trezor, a message from our CTO, and more!
Let’s dive into the latest updates and insights from Trezor.
Hi!
I’m Tomáš Sušánka, Chief Technology Officer at Trezor.
I might be an exception in the crypto space because I’ve been working at Trezor since 2017, which is a long time to stay with one company in this industry!
I’ve watched Trezor grow from a team of 20 into a company of around 200 people that still holds onto its crypto-punk roots, staying true to open-source principles and user-first values. Something I’ve learned is that in crypto, there are no boundaries. Whether you’re in Prague (Trezor headquarters) or San Francisco, you can build innovative products that change the world.
As someone responsible for Trezor’s technological strategy, I strive to balance usability, security, and privacy. This delicate balance is our unique selling point. Despite being fully open-source, this part of Trezor cannot be cloned.
There’s a saying in the security world that I love and firmly stand by:
“Security at the cost of usability comes at the cost of security.”
That captures exactly what we’re fighting for. Self-custody solutions must be both secure and easy to use because if people avoid them due to complexity, the whole point of crypto security falls apart.
One of the biggest challenges ahead is that it’s not just security tools getting smarter, scammers are too. Social engineering scams are becoming more sophisticated. My advice? Stay alert. Only buy devices from official sources. Never share your wallet backup. Enter the wallet backup only into a Trezor device. Always check the links you receive. And remember: our support will never reach out to you first.
Lastly, a quick note on why we support fewer coins than others: security. We only add coins when we’re sure they’re safe for users to manage. That’s also why I’m pushing for human-readable signing across the industry — to stop blind signing attacks like the Bybit hack.
Thanks for standing with us in building open-source tools that protect your digital freedom.
Take control.
Tomáš Sušánka
Chief Technology Officer at Trezor
