A code audit examines the smart contract source code for vulnerabilities — reentrancy, access control flaws, integer overflows, logic errors. It is a necessary but insufficient component of a security program. A full security review includes the code audit plus: economic modeling of incentive exploits (can someone game your tokenomics?), infrastructure review (key management, deployment pipelines, multisig configurations), and threat modeling for the specific attack vectors your protocol faces.

For token launches specifically, the economic layer matters as much as the code layer. A technically secure contract with exploitable tokenomics is still a vulnerable system. If you are designing your token's economic model, Forgd's tokenomics tools can help stress-test your parameters before they go to audit.
