Atomic Wallet review

Do not put bitcoin in Atomic Wallet, and if you already have some there, move it. Over two days on June 2 and 3, 2023, users across bitcoin, Ethereum, TRON, XRP, Litecoin, Dogecoin, BNB, Polygon and Stellar watched their balances leave at once. Elliptic put the losses above $100 million across more than 5,500 wallets, one of the largest thefts ever suffered by the users of a single self-custody wallet, and attributed the operation to North Korea's Lazarus Group based on laundering patterns matching earlier state linked thefts, including funds pushed through the Sinbad mixer.

What makes this a caution rather than a bad month is everything that came after. Atomic first said under 0.1% of users were affected, then under 1%, figures that did not survive contact with the on-chain evidence. It listed four possible causes, device malware, an infrastructure breach, injected code and a man in the middle attack, and never said which one it was. No compensation has been paid. Two US class actions have made the same allegation, that the company knew of security problems from a 2021 audit and did not act on them. The first, Meany v. Atomic Protocol Systems in Colorado, was dismissed on September 10, 2024 because the court found it had no personal jurisdiction over an Estonian company and a UAE one, which settled nothing about whether the allegation is true. A second, Alasu v. Atomic Protocol Systems, was filed in the Northern District of California on June 5, 2025 and amended that November.

Then there is the website. Read atomicwallet.io today and you would never learn any of this happened. The homepage advertises "Trusted by 15,000,000 users worldwide", promises no accounts, no verification and no KYC, and still carries testimonial cards attributed to CZ, Charlie Shrem and John McAfee, who died in 2021. There is no incident notice, no post-mortem, and no link to one anywhere on the page. A wallet may survive being attacked. Declining to explain it to the next person who downloads it is a separate decision, and it is the one this record is about.

If you still hold coins in Atomic Wallet, the safe move is not to import your recovery phrase into a new app. If that phrase was exposed in 2023, importing it carries the exposure with it. Create a brand new wallet elsewhere, with a phrase generated on a device Atomic never touched, and send the coins to it.
