A smart contract audit team is selecting tools to automate the detection of common vulnerabilities like reentrancy and integer overflow. They want to integrate the tools into their CI/CD pipeline. Which tool selection is most appropriate?

Use a blockchain explorer to monitor transactions for vulnerabilities.

Use a unit testing framework only, and rely on developers to write tests for every vulnerability.

Use a static analysis tool like Slither and a fuzzing tool like Echidna, and run them as part of the CI pipeline.

Use a manual code review checklist and a text editor to search for common patterns.

A smart contract has a complex function that processes user-supplied data. The team wants to uncover edge-case vulnerabilities that might not be covered by manual tests. Which approach is most effective?

Deploy the contract on a testnet and invite users to test it

Use a fuzzing tool to generate random inputs and monitor for reverts or unexpected behavior

Write additional unit tests for the function with various inputs

Perform a manual review of the function's logic
