What are the critical security features of the latest Trezor.io/start v25.7.4 version

The latest Trezor.io/start v25.7.4 introduces several critical security features and enhancements:

• Passphrase wallet flow improvements: The process for opening or creating passphrase-protected wallets has been refined, delivering clearer guidance to users. This workflow not only boosts user confidence but also reduces the risk of errors, ensuring your assets are accessed only by you.
• Solana address validation: New safeguards alert users when attempting to send funds to risky system-derived token or staking addresses, enhancing protection against common user mistakes and attacks on the Solana network.
• Wallet Connect transaction previews: Users now see transaction details before confirming any action via Wallet Connect, increasing transparency for EVM-based operations and reducing the risk of accidentally signing malicious transactions.
• Address poisoning protection: Trezor Suite proactively detects and flags suspicious transactions that may be part of address poisoning attacks—helping you avoid receiving tokens from malicious actors.
• PIN and passphrase security: All sensitive operations, such as transaction signing and wallet management, require device-level PIN confirmation and optionally a unique passphrase, isolating your private keys from software threats.
• Firmware authenticity checks: When connecting your device, Trezor Suite verifies firmware integrity to prevent potential attacks from counterfeit or tampered devices.
• Discreet mode: You can activate this feature to hide sensitive account balances and activity from possible onlookers, further protecting your privacy in shared environments.
• Transaction and message clarity: Enhanced previews for EIP-712 messages and 1inch Fusion swap details help users verify exactly what they're signing, strengthening defenses against phishing and social engineering.
• Frequent fee rate updates: Blockchain transaction fee rates are now updated every minute so estimates remain current and less prone to manipulation.
• Tor integration: By routing connections through the Tor network, users benefit from increased privacy against network observers.
• Separate passphrase wallets: The suite enables the use of multiple hidden wallets from the same seed phrase, protected by different passphrases. This allows experienced users to compartmentalize funds and mitigate the risk of compromise.

These security upgrades, combined with a transparent, open-source codebase and regular security audits, ensure that Trezor Suite v25.7.4 continues to set high standards in digital asset protection.
