| Singapore | Strict DPTO licensing |
6. Conclusion
2024’s attacks reveal persistent gaps in private key storage and DeFi protocol audits. While regulatory advancements like MiCA improve accountability, stakeholders must prioritize:
- Multi-signature wallets for institutional custody.
- Third-party smart contract audits.
- Cross-border AML collaboration.
FAQ
Q: How can investors mitigate phishing risks?
A: Use hardware wallets, verify contract addresses, and avoid clicking unsolicited links.
Q: What makes Ethereum a frequent target?
A: High TVL ($100B+) and complex dApp ecosystems attract exploiters.
Q: Are stolen funds recoverable?
A: Only ~25% are typically frozen; decentralized protocols limit reversibility.
