According to WuTalk, UniSat has released a security update on August 2026. The browser extension wallet v1.7.19 has updated the default mnemonic length for new wallets from 12 words to 24 words and optimized the wallet creation and mnemonic management process. UniSat stated that this is part of a long-term security configuration upgrade. Existing 12-word wallets still comply with the BIP-39 standard, so there’s no need to migrate urgently just because of the default setting change. Several recent community security reports have also been addressed with fixes or reinforcements based on their impact. https://(wublock123.com)/news/unisat-wallet-default-mnemonic-12-to-24-no-action-needed-66284
