The Sola Incident is a clear example of how unverified and poorly protected smart contracts can be devastating in DeFi ecosystems. Without access controls, even simple functions like token withdrawals can be hijacked. The attacker used a patterned strategy, exploiting multiple unaudited projects with the same approach. By studying these incidents, crypto users and builders can learn to prioritize contract verification, access restrictions, and on-chain monitoring. Staying alert and informed is crucial for maintaining security in a decentralized world.
