Data platforms CoinGecko and on-chain security firm CER have released a ranking of the most popular self-custody crypto wallets, with MetaMask dominating the market. As self-custody awareness grows, wallet security is under increased scrutiny—yet most brands lack full audits or penetration testing.
Top 4 Wallets Control 66.6% Market Share
The report reveals that the top ten crypto wallets by installs cover 81.2% of global crypto users. Notably:
- MetaMask (2016) leads with 22.66 million downloads
- The top 4 wallets account for 2/3 of total market share
- Mobile app installs (61.6M) far exceed browser extensions/desktop apps (19.55M)

Why Self-Custody Matters
FTX's collapse accelerated self-custody adoption:
- 80% of users now store assets in hot wallets (CoinGecko)
- 70% still use CEXs, highlighting demand for exchange-backed self-custody solutions
Security Gaps: Only 13.3% Pass Penetration Tests
CER's security audit report found alarming gaps:
- Just 6/45 top wallets underwent penetration testing
- Only 3 wallets (MetaMask, ZenGo, Trust Wallet) tested their latest versions
Penetration testing simulates cyberattacks to identify vulnerabilities before launch—skipping this risks financial/reputational damage from exploits.
Key Security Insights:
- Most developers prioritize bug bounties over full audits due to cost
- Open-source wallets aren’t inherently secure unless combined with bounty programs
- Hardware wallets reduce hack risks but don’t guarantee transaction safety
- Security hierarchy: Browser extensions > Mobile apps > Desktop applications
- Established brands generally have stricter security reviews
Choosing a Secure Wallet: 6 Checklist Items
- Check CER’s wallet ratings
- Prefer audited brands with public test results

FAQs
Q: Is MetaMask still the safest wallet?
A: While widely used, its extension version has higher risks than newer mobile-focused alternatives like ZenGo.
Q: Should I avoid all closed-source wallets?
A: Not necessarily—some proprietary wallets (e.g., Ledger Live) undergo rigorous private audits.
Q: How often should wallets update?
A: Monthly updates with disclosed security patches are ideal. Avoid wallets stagnant for 3+ months.
Q: Are hardware wallets unhackable?
A: No—they’re resistant to remote attacks but can be compromised via physical tampering or supply-chain interference.
Q: What’s the biggest wallet security mistake?
A: Storing recovery phrases digitally (screenshots/cloud) instead of offline metal plates.
