As indicated by the blog entry published on September 9, SatoshiLabs’ new BTC firmware is currently accessible to download for both Trezor One and Trezor Model T. The firm additionally underscored that it intends to present a “stable version” of Bitcoin-only firmware in the next month’s rollout, saying:
“From now on, we will be producing four different versions of firmware — regular (full altcoin support + U2F/WebAuthn) and Bitcoin-only, for both Trezor One and Model T. […] We have created a customized version of both our firmware and Wallet designed for everyone who supports the idea of Bitcoin. Every Bitcoin maximalist can now enjoy the Wallet interface with nothing else but Bitcoin.”
According to the announcement, to install the new firmware, clients will require Trezor Model T (version 2.1.0 or more current) or Trezor One, access to Trezor Beta Wallet or trezorctl, and a right firmware installation file.
As previously reported in March, Trezor’s immediate rival — hardware crypto wallets maker Ledger — unveiled five purported vulnerabilities in Trezor One and Trezor Model T.
Accordingly, Trezor later guaranteed that none of the shortcomings uncovered by Ledger are “critical” for hardware wallets. It was expressed that none of them can be abused remotely, as the attacks portrayed require “physical access to the device, specialized equipment, time, and technical expertise.”
