Important Security Notice Regarding Web Wallet

We recently identified and resolved a vulnerability affecting the Minima Web Wallet infrastructure.

The issue may have allowed a malicious actor to scan exposed private keys and access funds belonging to some Web Wallet users who logged in between 20th March and 8th May.

If you used Web Wallet during this period, we strongly recommend that you:

• Check your wallet balance and transaction history immediately
• Review for any unauthorised transactions or unexpected transfers
• Contact querysupport@minima.global as soon as possible if you believe your wallet may have been impacted
• Generate a new wallet to create a fresh set of private keys
• Move your funds to the newly generated wallet as a precautionary security measure

We want to be fully transparent with the community. Significant effort and industry best practices were applied to secure the infrastructure supporting Web Wallet. However, no internet-connected software or platform can ever be guaranteed to be 100% secure.

This challenge is becoming increasingly difficult across the entire industry, particularly in the era of AI-driven vulnerability discovery and automated exploitation.

As always, the most secure way to protect your tokens is to run your own Minima node and maintain full self-custody of your private keys. Self-custody removes reliance on hosted infrastructure and significantly reduces exposure to third-party attack surfaces.

We sincerely apologise for the concern this may cause and are continuing to investigate, monitor, and strengthen our systems.

Thanks,
Your Minima Team
