How to audit smart contracts with your AI

Connect Cronoscan to your agent to pull on-chain data for technical analysis. Once connected, your AI can inspect code and interfaces without you leaving your chat.

Short answer

How can I audit smart contracts using my AI?

Your agent pulls the verified source code and ABI directly from the Cronos block explorer. This lets you run security checks and logic audits on live contracts immediately. You get a breakdown of the technical outcomes below.

Audit outcomes.

What your agent produces.

The results of a technical inspection.

LOGIC

Vulnerability checks

The AI reads the source code to find common patterns like reentrancy. You get a list of specific lines to check.

INTERFACE

Function analysis

By pulling the ABI, your agent understands how to interact with the contract. This helps in testing function inputs.

STANDARDS

Compliance reports

The AI compares the contract against standards like ERC-20. It flags deviations from expected behavior.

HUMAN

Manual review needed

The AI flags suspicious logic, but you must perform the final sign-off. You make the call on the security impact.

The workflow

What your AI does when a contract address is provided.

The agent uses the Cronoscan MCP to fetch the data needed for a technical review.

  1. Fetch source code

    The agent grabs the verified Solidity or Vyper code from the block explorer to see what is deployed on-chain.

    get_source_code

  2. Retrieve ABI

    It pulls the Application Binary Interface to map out the contract's functions and parameters.

    get_abi

  3. Inspect bytecode

    If source code isn't available, the agent can look at the raw contract code to understand the logic.

    proxy_eth_get_code

  4. Analyze logic

    The agent combines the code and ABI to run security checks and identify potential flaws.

    get_source_codeget_abi

  • Audit the smart contract at 0x123... and look for reentrancy vulnerabilities.

  • Get the ABI for 0xabc... and explain how the transfer function works.

  • Check the source code for 0x789... to see if it follows ERC-20 standards.

  • Pull the code for 0xdef... and summarize the access control logic.

FAQ

How the audit process behaves

  • 01

    Can the AI deploy or change the smart contract?

    No. The AI can only read data from the blockchain. It cannot execute transactions or modify code.

  • 02

    What happens if the source code isn't verified?

    The AI will use the bytecode instead. It can still analyze the logic, but the results are harder to interpret than verified source code.

  • 03

    Does the AI replace a professional auditor?

    No. The AI acts as a first-pass tool to find flaws and summarize logic. A human must always perform the final security review.

  • 04

    Can I audit contracts on Ethereum using this?

    No. This specific connector is built for the Cronos blockchain.

  • 05

    Can the AI find hidden functions in the contract?

    Yes, by pulling the ABI and source code, the AI can identify all declared functions.
