Smart Contract Audit

A smart contract audit is a security review of contract code intended to identify vulnerabilities, design flaws, and other risks before or after deployment.

✦ Key Insight

Smart contracts can control large amounts of value, and programming errors may be difficult or impossible to reverse after exploitation.

✕ Common Misconceptions

An audit is not a guarantee of safety. Scope can be limited, code can change afterward, and vulnerabilities can remain undiscovered.

Detailed Explanation

Auditors examine how a smart contract behaves and whether attackers could exploit it. Reviews may combine manual code analysis, automated tools, testing, and formal methods.

In Practice

“Before launching a lending protocol, a team hires independent security researchers to review its borrowing, liquidation, access-control, and oracle logic.”

Smart Contract

A smart contract is blockchain-deployed code that can hold state and execute predefined rules when called.

Due Diligence

Due diligence is the process of investigating and verifying important information before making a decision or taking financial risk.

Honeypot Token

A honeypot token is a malicious or heavily restricted token that users can buy but ordinary holders cannot successfully sell under normal conditions.

Contract Verification

Contract verification demonstrates that published smart-contract source code compiles to bytecode corresponding to the code deployed at a blockchain address.

Proxy Contract

A proxy contract forwards calls to separate implementation code and can, in upgradeable designs, allow that implementation to be replaced later.
