Atomic Wallet review 2026: is it safe after the 2023 hack?
Atomic Wallet is an easy multi-coin wallet for desktop and mobile with built-in swaps and staking, but it is closed source, charges a 0.5% swap fee on top of partner costs and has never published a root cause for the June 2023 theft of more than $100 million from users. We do not recommend it for savings.
Status (as of October 2026): Active. Developed by Atomic Protocol Systems OÜ, an Estonian company (App Store listing, Oct 2026), led by CEO Konstantin Gladych. Atomic says it has 15 million users (atomicwallet.io, Oct 2026), up from about 5 million it cited in June 2023 (Decrypt, Jun 2023). Recent changes: Windows 7 and 8 support dropped (Windows 10 and 11 only), and when we checked, Atomic's downloads page said the iOS app was "temporarily unavailable" in the App Store, even though Apple's listing was still visible to us. A new US class action over the 2023 hack was filed in June 2025 (Bradley/Grombacher press release, 5 Jun 2025).
Verdict
Atomic Wallet looks friendly. One app handles Bitcoin, Ethereum, Solana, XRP, Monero and hundreds of tokens, with swaps, card purchases and staking built in. For someone who wants everything in one place, that is attractive.
The problem is trust. In June 2023, thousands of users lost more than $100 million in a theft that blockchain analysts linked to North Korea's Lazarus Group (Elliptic, Aug 2023). More than three years later, Atomic still has not said how it happened. The code is closed, so outsiders cannot check whether the cause was fixed, and there is no hardware wallet support to protect larger amounts. If you like the all-in-one design, Exodus or Trust Wallet offer similar convenience with a better track record.
At a glance
| Feature | Atomic Wallet |
|---|---|
| Type | Software wallet (desktop, mobile, browser extension) |
| Custody | Self-custody. A 12-word backup phrase and encrypted keys stay on your device |
| Chains | Atomic claims 1,000+ coins and tokens, including Bitcoin, Ethereum, Solana, XRP, Cardano, Monero, Dogecoin, Tron and BNB Chain (atomicwallet.io, Oct 2026) |
| Platforms | Windows 10/11, macOS, Ubuntu, Debian, Fedora, Android, iOS (see status note) and a Chrome extension |
| Open source | No. Some libraries are public, but the apps are closed source |
| Audits | Least Authority reviewed the wallet in 2021 and reported design flaws that could lead to total loss of funds (CoinDesk, Feb 2022). No later public audit that we could find |
| Hardware wallet support | None. Atomic's help centre says it has no native Ledger or Trezor integration |
| Price | Free |
Fees
| Action | Cost (as of October 2026) |
|---|---|
| Send and receive | Network fee only. Atomic says it adds no extra fee |
| Swaps | 0.5% Atomic fee plus the swap partner's commission, built into the quoted rate (Atomic help centre, Oct 2026) |
| Buy with card | Through third-party providers such as Simplex and MoonPay, at their rates, with KYC (KuCoin review, Mar 2026) |
| Staking | Network fee to delegate; validators keep a commission from rewards. We could not confirm whether Atomic adds its own cut |
The swap quote already includes every fee, so the only way to judge the price is to compare the amount you will receive with another service. Swaps through partner exchanges are usually more expensive than trading on an exchange or a large DEX aggregator. See wallet fees compared.

Security model
Atomic is a standard hot wallet. Your keys and backup phrase are encrypted with your password and stored on your computer or phone. Atomic says it never holds them and needs no account or KYC for basic use. That design is fine in principle, but it only protects you if the software itself is sound, and with closed code you have to take Atomic's word for that.
Incident history
| Date | What happened | Response |
|---|---|---|
| Apr 2021 to Feb 2022 | Security firm Least Authority audited Atomic and warned that users were vulnerable to attacks that could cause total loss of funds, citing cryptography issues, an incorrectly used Electron framework and outdated dependencies (CoinDesk, Feb 2022). | CEO Konstantin Gladych said some issues were patched, the rest would be fixed by Q2 2022 with a re-audit, and that none posed a risk to users. We found no published re-audit. |
| 3 Jun 2023 | Funds were drained from thousands of wallets. Elliptic put losses above $100 million across more than 5,000 wallets and attributed the theft to Lazarus (Elliptic, 2 Aug 2023). Atomic said fewer than 0.1% of its roughly 5 million users were affected (Decrypt, Jun 2023). | Atomic listed four possible causes (malware on users' devices, an infrastructure breach, injected code or a man-in-the-middle attack) but never confirmed one. It worked with exchanges and analytics firms to freeze funds; about $1 million was frozen by 14 June (Elliptic, via Decrypt). No reimbursement was announced. |
| 13 Jun 2023 | Authorities in Kazakhstan summoned Atomic's management for questioning and requested server logs (ForkLog, 13 Jun 2023). | No public outcome that we could find. |
| 10 Sep 2024 | A US federal judge in Colorado dismissed a class action by 21 users against Atomic and developer Evercode Infinite for lack of personal jurisdiction (Cointelegraph, 11 Sep 2024). | The ruling did not decide whether Atomic was negligent. |
| Jun 2025 | A new class action was filed in the US District Court for the Northern District of California, alleging Atomic ignored the 2021 audit findings (Bradley/Grombacher press release, 5 Jun 2025). | We could not confirm the case's status as of October 2026. |
The biggest concern is not that a hack happened, because many wallets have had incidents. It is that the root cause is still unknown, so nobody outside Atomic can say whether it was fixed. Compare our full wallet security incidents timeline.

Setting up safely
- Type the official domain
atomicwallet.ioyourself or use a bookmark. Search results for Atomic Wallet are full of fake "help" and "extension" pages hosted on site builders, which lead to phishing. - Download only from the official site, Google Play or the App Store, and check that the publisher is Atomic Protocol Systems OÜ.
- Create a new wallet and write the 12 words on paper. Never store them in a screenshot, cloud note or email.
- Set a strong password. It encrypts the wallet on that device, but it cannot recover your funds; only the 12 words can.
- Keep only what you would be willing to lose. Move savings to a hardware wallet such as a Ledger or Trezor, since Atomic cannot connect to one.
Atomic support will never ask for your backup phrase. Anyone who does is a scammer. More in fake wallet apps and seed phrase safety.
Pros and cons
| Pros | Cons |
|---|---|
| Supports a very wide range of coins in one app | More than $100 million stolen from users in 2023, root cause never published |
| Desktop (including Linux), mobile and extension | Closed source, so outsiders cannot verify fixes |
| Built-in swaps, staking and card purchases | 0.5% swap fee plus partner commission |
| No account or KYC for basic use | No hardware wallet support |
| Simple interface | No reimbursement for 2023 victims; litigation ongoing |
Who it suits, and who should look elsewhere
It can suit someone who needs a desktop wallet for a less common coin, such as Monero or Dash, and keeps only small amounts in it.
Look elsewhere if you are storing savings, want open-source code, or want to pair your wallet with a hardware device. Beginners are better served by a wallet with a cleaner security record.
Alternatives
- Exodus: a similar desktop and mobile multi-coin wallet with Trezor support.
- Trust Wallet: a large multi-chain mobile wallet; see Trust Wallet vs Exodus.
- Electrum: an open-source desktop wallet if you only need Bitcoin.
