What Is Atomic Wallet?
Atomic Wallet is a multi-chain, non-custodial cryptocurrency wallet available on Windows, macOS, Linux, iOS, and Android. It was founded in 2017 by Konstantin Gladych, previously a founder at Changelly.
The wallet is designed as an all-in-one tool for managing a diverse crypto portfolio. Rather than using multiple wallets for different chains, Atomic Wallet’s pitch is that you can hold Bitcoin, Ethereum, Solana, Cardano, Cosmos-based assets, and 300+ other coins in a single interface with built-in swap and staking capabilities.
Atomic Wallet stores private keys locally on your device. They are encrypted with your password and never sent to Atomic Wallet’s servers. This is the standard non-custodial architecture.
The 2023 Security Incident: What You Need to Know
In June 2023, Atomic Wallet suffered a serious security breach. Approximately $35 million in user funds were drained from wallets, with some estimates putting the figure higher. Blockchain analytics firms including Elliptic attributed the attack to the Lazarus Group, a North Korean state-sponsored hacking organization responsible for several other major crypto thefts.
What happened: Users reported that funds disappeared from their wallets without any action on their part. Different attack vectors were suggested, including a compromised supply chain (malicious code inserted into a wallet update), a compromised dependency, or a breach of user data.
Atomic Wallet’s response: Atomic Wallet disputed the highest estimates of losses and hired a security firm (Mandiant) to investigate. The company stated that less than 0.1% of monthly active users were affected. The company did not fully disclose the root cause of the attack publicly.
Legal actions: Affected users filed class action lawsuits in US federal court against Atomic Wallet. The legal proceedings were ongoing as of 2026.
What it means for you:
The 2023 incident is a serious data point that any prospective Atomic Wallet user must weigh. The attack demonstrated that the wallet software itself may have been compromised — not just individual users making mistakes. For a wallet that stores private keys locally, this represents a fundamental security failure.
This does not mean Atomic Wallet is necessarily unsafe today. The company updated its software post-breach and states it has strengthened security measures. But it does mean that users should:
- Be aware this incident occurred
- Not store large amounts in Atomic Wallet without understanding the risk
- Consider alternatives if security is the primary concern
- Use Atomic Wallet only for amounts they can afford to lose
We present this information transparently because making an informed decision requires knowing the full history.
Key Features
300+ Supported Assets
Atomic Wallet supports one of the widest asset ranges in the non-hardware wallet category:
| Category | Examples |
|---|---|
| Bitcoin | BTC, BTC SegWit |
| Ethereum and ERC-20 | ETH, USDT, USDC, thousands of tokens |
| BNB Chain | BNB, BEP-20 tokens |
| Solana | SOL, SPL tokens |
| Cardano | ADA |
| Polkadot | DOT |
| Cosmos ecosystem | ATOM, OSMO, others |
| Ripple | XRP |
| Litecoin | LTC |
| Tron | TRX, TRC-20 |
| Algorand | ALGO |
| Stellar | XLM |
| Avalanche | AVAX |
| And 250+ more | Various |
The breadth of support is genuinely impressive. For users holding a diverse portfolio across many chains, the ability to see everything in one interface has real value.
Built-In Exchange
Atomic Wallet has two exchange mechanisms:
Atomic Swaps: True peer-to-peer atomic swaps for BTC/LTC and a few other pairs that support the HTLC protocol. These swaps are genuinely trustless — no third party holds your funds during the swap. However, atomic swap pairs are limited, and they require both sides of the trade to have compatible protocols.
Centralized Exchange Integration: For the vast majority of swaps, Atomic Wallet uses centralized exchange partners (including Changelly and others) rather than true atomic swaps. The “atomic” branding can be misleading here — most swaps go through a centralized intermediary. You send your coins to the exchange service, they process the swap, and send back the new coins. This is convenient but is not trustless.
Users should understand this distinction: the wallet is called “Atomic Wallet” and supports some atomic swaps, but most in-wallet exchanges use centralized services.
Staking
Atomic Wallet supports staking for 25+ cryptocurrencies directly within the wallet. Supported staking coins include:
- Cardano (ADA) — ~3-4% APY
- Cosmos (ATOM) — ~15-20% APY
- Solana (SOL) — ~6-7% APY
- Tezos (XTZ)
- Algorand (ALGO)
- Polkadot (DOT)
- Kusama (KSM)
- Zilliqa (ZIL)
- NEO
- Ontology (ONT)
- And others
Staking rewards vary and are subject to network conditions. Atomic Wallet displays estimated APY rates within the interface.
Note on staking custody: Staking in Atomic Wallet may involve delegating to Atomic Wallet-operated validators in some cases. Understand the staking mechanism for each coin before delegating significant amounts.
Desktop and Mobile Availability
Atomic Wallet’s availability across all major platforms is a genuine differentiator:
- Windows
- macOS
- Linux
- iOS
- Android
Most wallets are either mobile-first or desktop-first. Atomic Wallet is one of the few wallets that offers a genuinely feature-complete experience on both desktop and mobile.
Portfolio Overview
The wallet provides a portfolio view showing all your assets, their current values in USD or other fiat currencies, and portfolio allocation by asset and category. This is useful for users managing multiple assets who want a consolidated view.
Private Key Management
Atomic Wallet stores your 12-word seed phrase and derived private keys locally, encrypted with your password. The company states that private keys never leave your device.
However, as the 2023 incident showed, local private key storage does not guarantee safety if the wallet software itself is compromised. The encryption of private keys is only as good as the integrity of the software accessing them.
Setting Up Atomic Wallet
Desktop Installation
- Download Atomic Wallet from atomicwallet.io. Verify you are on the official website — phishing sites exist.
- Install the application on your operating system
- Launch the app and select “Create Wallet”
- A 12-word mnemonic phrase is generated. Write it down on paper. Store it offline and securely. Do not take a screenshot.
- Set a strong password for the wallet
- Verify your mnemonic by confirming the words in order
- The wallet is ready
Mobile Installation
The process is identical on iOS and Android. Download from the App Store or Google Play. Verify the publisher is Atomic Wallet.
Importing Existing Wallet
If you have an existing 12-word or 24-word seed phrase, select “I already have a wallet” and enter your phrase to import your addresses.
Is Atomic Wallet Safe in 2026?
This is a nuanced question that deserves a direct answer.
What the 2023 breach demonstrated:
- The wallet software itself was likely compromised, meaning the attacker could access private keys despite local encryption
- The company did not fully disclose the attack vector, making it impossible to fully evaluate whether the root cause was addressed
- North Korean state-sponsored hackers specifically targeted Atomic Wallet users, suggesting the wallet was a high-value target
Arguments for continued use (with caution):
- The company updated software after the breach
- Local private key storage is fundamentally sound if the software is uncompromised
- Millions of users continue to use Atomic Wallet without incidents since the 2023 breach
- The wallet’s multi-chain breadth has no direct replacement
Recommended approach if using Atomic Wallet:
- Use it only for amounts you can afford to lose entirely
- Keep large holdings on hardware wallets (Ledger, Trezor, Keystone) or purpose-built secure wallets
- Keep software updated to latest versions
- Download only from the official website
- Enable password protection
For large holdings, consider using chain-specific wallets (Phantom for Solana, MetaMask for ETH, etc.) rather than Atomic Wallet, and moving long-term holdings to hardware wallets.
