Atomic Wallet review 2026 examines Monero support after the 2023 hack. We assess current safety for XMR users based on verified incidents, fixes, and ongoing complaints.
Atomic Wallet functions as a non-custodial multi-asset software wallet. Private keys and the 12-word recovery phrase are generated and stored locally on the user device, encrypted by a password, and never transmitted. The wallet supports over 1,000 coins and tokens across dozens of blockchains.
Native Monero support covers deposits, sends, swaps, and balance management. An update released January 19, 2023 resolved earlier synchronization and display problems; deposits made after that date require no further action, while older balances may still need a support-assisted rescan with the view key. The company has never released its full source code.
Users can access in-app swaps through third-party liquidity providers, staking for selected assets, and fiat on-ramps via partner services where KYC requirements may apply at the provider level. The application runs on Windows, macOS, Linux, iOS, and Android, with an additional browser extension option. The official site states the wallet is trusted by 15,000,000 users worldwide.
Elliptic’s June 13, 2023 analysis placed losses above $100 million spread across more than 5,500 wallets. On-chain researcher ZachXBT’s early June tracking showed at least $35 million moved, with some contemporaneous reports later suggesting totals could exceed $50 million as additional victims surfaced.
Both sets of figures were attributed to the Lazarus Group on the basis of consistent laundering patterns through mixers such as Sinbad and exchanges including Garantex. Atomic Wallet’s June 5, 2023 statement initially claimed the incident affected under 0.1 percent of monthly active users; the company later revised that figure upward to less than 1 percent.
The exact root cause was never disclosed. Atomic listed four possible attack vectors but did not confirm which, if any, had been exploited. No compensation was paid to affected users, and the company’s public materials contain no reference to the event.
Atomic Wallet encountered additional security issues after the 2023 incident. On April 10, 2025, a malicious npm package named pdf-to-office targeted older Windows builds (versions 2.91.5 and 2.90.6) of the wallet and Exodus by patching local files to redirect outgoing transactions. Users were advised to verify installations and avoid untrusted packages.
In August 2026, multiple Trustpilot reviews described unauthorized withdrawals of BTC, ETH, and USDT, including cases where devices remained offline and seed phrases were stored separately. Two U.S. class-action lawsuits alleged that the company knew of security issues from a 2021 audit yet failed to act. The Colorado case was dismissed on September 10, 2024, for lack of personal jurisdiction. A California case filed on June 5, 2025, was amended in November 2025. No compensation has been paid to victims.
No new confirmed mass-drain events matching the 2023 scale have been independently verified beyond these user complaints.
Atomic Wallet resolved earlier Monero synchronization and balance-display problems through an update that took effect on January 19, 2023. Deposits sent after this date process normally without the previous display or sync errors. Pre-fix users may still encounter incomplete balances and can require support-assisted rescans that rely on their view key to correct the record.
The company has never published its full source code. Official documentation also omits any post-incident audit reports that would confirm the 2023 vulnerabilities were fully closed.
No quantified figures on Monero transaction fees or success rates are available from primary sources. Users must rely on general statements rather than measurable performance data when evaluating the wallet for ongoing XMR activity.
| Wallet | Custody Model | Source Availability | Monero Sync Method | Known Incident History | Platform Coverage |
|---|---|---|---|---|---|
| Atomic Wallet | Non-custodial; private keys and 12-word phrase generated and stored locally, encrypted with password | Full source code never published | Monero sync and balance issues fixed in update effective January 19, 2023; pre-fix deposits may require support-assisted rescans using view key | June 2023 incident with losses exceeding $100 million across more than 5,500 wallets (Elliptic analysis, June 13, 2023); additional user reports of unauthorized withdrawals in August 2026 | Windows, macOS, Linux, iOS, Android, browser extension |
The verified briefing supplies no data on any other non-custodial Monero wallets, so no further rows or comparisons are possible.
Atomic Wallet remains non-custodial with keys stored locally, yet user reports of unauthorized withdrawals continued into August 2026 even on offline devices. No independent verification confirms that the 2023 vulnerabilities have been fully closed.
Elliptic estimated losses exceeding $100 million across more than 5,500 wallets as of June 13, 2023. Atomic stated fewer than 1 percent of monthly active users were impacted, but no compensation has been paid to any victims.
Atomic addressed certain Monero synchronization problems in an update on January 19, 2023. However, the company has never published details on the root cause of the main breach or released post-incident audit results confirming full remediation.
Users should avoid running untrusted packages after the April 2025 malicious npm incident that targeted versions 2.91.5 and 2.90.6. Checking file integrity against official sources and monitoring outgoing transactions for unexpected address changes remains necessary.
Monero users seeking stronger verified privacy controls often consider dedicated wallets that publish full source code and maintain transparent security practices, as Atomic has not released its complete codebase.
No compensation has been paid to victims. Two U.S. class-action lawsuits alleging prior knowledge of security issues resulted in one dismissal for jurisdictional reasons, while the second case remains active without resolution.
