Trezor CEO Matěj Žák emphasized the future of Bitcoin and the critical role of self-custody in a recent interview. He discussed the company's latest hardware wallet, the Trezor Safe 7, which prioritizes open-source transparency and user privacy. The wallet includes an auditable secure element and a 90-day customer data deletion policy, reflecting Trezor's commitment to security and user control. Žák also noted the company's strategic shift to open-source design after encountering a vulnerability in a closed-source chip, leading to the development of Trezor's proprietary Tropic Square technology. The Safe 7 has experienced strong organic demand, underscoring the growing importance of self-custody in the cryptocurrency sector.
