Trezor shipped a useful late-July stack for people who actually use their devices day to day: firmware 2.12.2 (22 July) and a follow-up 2.12.3 patch (24 July), paired with Trezor Suite 26.7.x. This is not a flashy new hardware launch — it is the kind of release that quietly reduces signing mistakes and closes edge-case gaps.
What changed in firmware
Firmware 2.12.2 focuses on transaction review quality:
- Solana — clearer confirmations for instruction parameters that used to stay hidden, plus fixes for token transfer recipients when Address Lookup Tables (ALTs) are involved.
- Ethereum — improved clear-signing coverage so more of what you approve is readable on-device.
- Tron — support for claiming voting rewards on-device.
- Bitcoin — fixes around external input misidentification and rejecting risky patterns in replacement transactions.
- Bitcoin-only firmware — an explicit error when something tries to derive a seed path that does not belong on BTC-only builds.
2.12.3 is a small but important stability fix for Safe 3 / Safe 5 (and related models) that could crash during PIN verification when upgrading from firmware older than 2.9.0.
What Suite 26.7 adds
Suite 26.7 is where most users will feel the update:
- Tron (TRX) staking available directly in Suite
- Cancel pending EVM transactions, plus view/edit nonce in the send form
- Expanded clear signing coverage for trading flows (including 1inch-related paths)
- WalletConnect entry point from the account menu
- Lower Bitcoin minimum fee option (0.2 sat/vB for Normal priority)
- Firmware prompts that pull in the security improvements for Safe 7, Safe 5, Safe 3, and Model T
If you use Trezor mainly for Bitcoin, the fee and signing fixes still matter. If you use Solana or EVM DeFi, the confirmation and cancel/nonce tools are the headline.
Who should update
- Safe 7 / Safe 5 / Safe 3 owners — update Suite first, then accept the firmware prompt from official channels only.
- Anyone stuck on firmware older than 2.9.0 — take the 2.12.3 path carefully; the PIN-upgrade crash fix exists for a reason.
- Solana and EVM power users — this release is aimed at you; older firmware will keep working, but you will miss clearer on-device reviews.
Always download Suite from trezor.io (or the vendor's official GitHub releases). Ignore email or chat “update” links — that pattern is exactly how phishing waves start after security news.
WalletLab take
Firmware hygiene is part of self-custody. A polished Suite feature is nice; accurate on-device review is what actually protects funds when a dApp or browser extension lies.
