Trezor Suite October 2026 update expands passphrase length to 128 characters, adds support for Soroban smart contract tokens on Stellar, brings Arc network tokens into the wallet, and adds Cardano mobile sending alongside trade history CSV export.
Trezor Suite's October update focuses on security and asset coverage. The headline feature is extending passphrase length from 50 to 128 characters—prompted by the Coldcard firmware vulnerability that drained thousands of wallets this summer. Users with strong passphrases were protected, spurring demand for longer secret recovery phrases that can open separate wallets on the same device. The update also adds support for Soroban smart contract tokens (SEP-41 standard) on Stellar, lets you hold and send USDC and other tokens on Circle's Arc network, and brings Cardano sending to mobile. A new CSV export for trade history lets users keep records in spreadsheet tools and accounting software.
