Smart Contract Security and Common Vulnerabilities
Smart contract security is the practice of designing, developing, testing, auditing and operating blockchain-based programs so that they behave correctly and resist unintended or malicious use.
Smart contracts are programs stored and executed on blockchain networks. They can automatically enforce rules for applications involving payments, decentralized finance, digital assets, token systems, governance and many other use cases.
The major advantage of a smart contract is that its rules can be executed automatically without requiring a traditional intermediary for every operation. However, this also creates an important security challenge: a programming error can become a financial or operational vulnerability.
