Vitalik Buterin has called for better wallet security that protects users from losing cryptocurrency, not only from hackers. In a recent exchange on social media, the Ethereum co-founder pointed to forgotten passwords, lost devices, software failures and missing backups as common ways users can permanently lose access to their assets.
These losses are different from theft because there may be no attacker to blame. Buterin argued that wallet providers and the wider crypto industry should treat accidental loss as a serious security problem rather than an unavoidable consequence of self-custody.
Reminder: there’s also plenty of people who have lost huge amounts of crypto to *loss* rather than theft.
Software bug, forgotten password, lost device, paper wallet burned down in LA fire, upgraded device without backing up data …. lots of ways for that to happen.
Because…

Why crypto loss remains difficult to solve
Self-custody gives users control over their private keys, but that control also makes recovery difficult. MetaMask’s current guidance, for example, warns that users who lose their Secret Recovery Phrase and do not have another supported recovery method may permanently lose access to their accounts.
One of the most well-known examples of permanent loss involves James Howells, who says a hard drive containing the private key for 8,000 Bitcoin was accidentally discarded in 2013. His case illustrates the problem particularly clearly: the Bitcoin remains on the blockchain, but access depends on recovering the private key stored on the missing drive. A 2025 High Court judgment confirmed that the Bitcoin itself does not physically exist on the hard drive or in the landfill.
Howells has also pursued legal efforts to access the landfill, following his earlier crypto loss story. His appeals were rejected in 2025, and he later moved away from plans to excavate the site.
Social recovery offers another approach
Buterin has long advocated social recovery wallets, which allow trusted guardians to help a user replace a lost key without giving those guardians control over the user’s funds during normal use.
The model addresses a weakness in the traditional single-key wallet. If the key is stolen, a hacker can potentially take the funds. If the key is lost, the legitimate owner can face the same outcome without any attacker being involved.
That makes recovery design an important part of wallet security. Better backup systems, recovery mechanisms and user education could reduce losses without removing the self-custody features that attract users to crypto.
The issue also extends beyond accidental loss. HTX Global Advisor Justin Sun previously called for stronger crypto security after a major exchange hack, highlighting the industry’s separate challenge of protecting assets from active attackers.
For wallet providers, the challenge is therefore broader than preventing theft. A secure wallet also needs to give legitimate users practical ways to recover access when keys, devices or backups fail.
