What Is Smart Contract Audit?
Definition
A smart contract audit is a professional security review of code — identifying vulnerabilities, logic errors, and attack vectors before deployment.
Auditors review code line by line for reentrancy attacks, integer overflows, access control issues, and economic exploits.
- Standard tokens from CoinDevTools — NO audit needed. Battle-tested templates.
- Custom smart contracts — YES. Any custom Solidity or Rust code should be audited.
- DeFi protocols — YES. Protocols managing user deposits MUST be audited ($5K-100K+).
Audit firms: Trail of Bits, OpenZeppelin, Certik, Halborn, Ackee Blockchain.
