In late December 2025, Trust Wallet suffered a serious security breach affecting its Chrome browser extension version 2.68. A malicious update released around December 24 contained hidden code that silently extracted users’ decrypted seed phrases after wallet unlock. As a result, attackers rapidly drained approximately 7 million dollars across multiple blockchains, including Bitcoin, Ethereum, and Solana.

The incident was first flagged on Christmas Day by on chain investigator ZachXBT. Investigations revealed a classic supply chain attack. Malicious code was implanted as early as December 22 and sent sensitive data to a fake domain designed to mimic Trust Wallet’s analytics infrastructure. Once seed phrases were exposed, wallets were irreversibly compromised.

Trust Wallet responded quickly by releasing version 2.69 on December 25 and urging immediate updates. The mobile app and other platforms were not affected. Trust Wallet, supported by Binance founder Changpeng Zhao, confirmed full reimbursement for victims through its support process, backed by funds such as Binance SAFU.

While refunds softened the impact, the incident highlights a critical reality. Software wallets remain vulnerable to malicious updates, compromised dependencies, and silent data exfiltration. Once a seed phrase is exposed in a software environment, security is permanently lost.

Serenity follows a fundamentally different approach. With sAxess, a biometric hardware card, and sBox secure storage, private keys and seed phrases never exist in an exposed software environment. They remain isolated in hardware and accessible only through biometric verification, making silent extraction or remote theft impossible even during compromised updates.

True self custody starts with eliminating attack vectors, not reacting after damage is done.
