To build a more effective smart contract security risk assessment system, multi - layer verification is crucial. Firstly, conduct formal verification, which uses mathematical methods to prove the correctness of the code logic. Secondly, employ experienced third - party auditing firms that specialize in blockchain security. They can identify common vulnerabilities like re - entry attacks and integer overflow. Additionally, implement continuous monitoring after deployment, tracking any abnormal contract behavior in real - time to detect potential risks promptly.​
