Which wallets survived hacks and how they responded
From 2018-2024, Ledger and Trezor secure chips were not mass-breached; users were hit via phishing and fake apps. Hot wallets like Atomic Wallet (2023, ~$100M) fared worse. POOL BTC covers BTC wallets: who survived incidents, how teams responded, and what to do after a breach headline.
TL;DR: hardware wallets survived data leaks and phishing because private keys never left the chip; good response = fast postmortem, signed updates, honest comms. After an incident: update firmware/app, enable 2FA, never type seed on websites. See also crypto cards after the bear market (CEX risk) and card security.
What counts as a wallet «surviving a hack»?
POOL BTC criteria: after a public incident the product stays online, the team ships a fix or official statement within 30 days, and self-custody architecture is intact (no seed leak from vendor servers). Exchange hacks (Mt.Gox, FTX) are custodial accounts, not wallet products.
Which wallets survived incidents with strong responses?
Six cases where users with proper hygiene kept self-custody and teams communicated clearly (June 2026, products still active).
| Wallet | Year | Incident | Keys/funds | Team response |
|---|---|---|---|---|
| Ledger | 2020 | customer DB leak (emails/addresses) | keys not leaked | email alerts, bounty, 2FA push |
| Trezor | 2020-2024 | phishing + counterfeit devices | 0 from chip | genuine check, open firmware |
| MetaMask | 2022-2024 | drainer phishing, not code hack | victims lost funds | blocklist, tx simulation, alerts |
| Electrum | 2018 | fake update binaries | users who installed fake | signed releases, warnings |
| BlueWallet | 2023 | Lightning vuln (patched) | minimal | 48h hotfix, postmortem |
| Sparrow | 2024 | dependency 0-day (fast) | 0 | public GitHub issue + release |
Where response was weak or losses large?
Not «all hot wallets are bad», but incidents with notable losses or slow communication.
| Wallet | Year | What happened | Communication | Lesson |
|---|---|---|---|---|
| Atomic Wallet | 2023 | unclear vector, ~$100M | slow status updates | lesson: unaudited hot wallet |
| Trust Wallet iOS | 2023 | Web3 module vuln | limited losses | patch, trust hit |
| MyEtherWallet | 2018 | CDN DNS hijack | some users | push to hardware signing |
*Amounts illustrative from public reports. Not financial advice. For BTC: prefer hardware signing + verify address.
How should users respond after a hack headline?
- Do not panic-type your seed on «urgent support» sites.
- Update only from the official site or app store; verify PGP/signatures.
- After email leak (Ledger 2020) - stronger passwords, hardware 2FA, expect phishing.
- Move large balances to a new address only if device compromise is plausible.
- Compare models in the POOL BTC wallet hub.

Frequently asked questions
Were Ledger or Trezor hacked so all devices lost BTC?
No mass breach of the Secure Element chip. There were customer DB leaks, phishing, and counterfeit hardware. Losses hit users who typed seed on fake sites or bought clone devices.
Was MetaMask hacked?
The extension was not mass-hacked to steal all keys. Losses came from approve scams and drainer sites. MetaMask added warnings and blocklists, but you still own every signature.
What to do after a Ledger email leak?
Expect phishing «urgent update» mail. Update only via ledger.com, never enter 24 words online. Consider a fresh receive address for large holdings.
Which wallet patched vulnerabilities fastest?
Open-source Bitcoin clients (Sparrow, BlueWallet) often ship in 24-72h with public issues. Ledger/Trezor cycles are slower due to firmware audit, but patches are signed.
Should I leave Atomic Wallet after 2023?
If you held serious funds in Atomic - yes, migrate to hardware + desktop signer (Sparrow, Ledger). Use hot mobile only for spending float.
