2. What is a smart contract audit? • Security auditing allows you to inspect your project's smart contract code. Contracts are typically written in the Solidity programming language and are available through GitHub. • Security audits are especially important for DeFi projects with multi-million dollar transactions or large numbers of participants.

3. An audit generally consists of four steps: • The audit team conducts a preliminary review of the smart contract. • The results of the analysis are provided to action items. • The project team makes changes based on the issues found. • The audit team issues a final report, taking into account new changes and remaining errors. Many users consider smart contract auditing when investing in new DeFi projects. Auditing is standard procedure for large projects. Meanwhile, reports from major audit firms are seen as more valuable in the eyes of investors.

4. Why do you need smart contract auditing? • Since smart contracts are used to transfer or lock important funds, they can be hacked. Small mistakes in code can lead to huge losses. • For example, the DAO hack on the Ethereum blockchain resulted in $60 million in ETH theft and a network hard fork. • Since blockchain transactions are irreversible, it is very important to ensure the security of the project code. The particularity of blockchain technology makes it difficult to withdraw funds. • To solve the problem after the fact, it is best to find possible loopholes in the project in advance.

5. How Smart Contract Auditing Works • Smart contract auditing is a fairly common service. While the audit firm's approach may vary slightly, a typical audit looks like this: • Determine the scope of the audit. The specification of a smart contract is determined by the purpose and overall architecture of the project. The specification helps audit teams understand the goals of the project when writing and using code. • Initial quotation based on workload. • test. Verification tools and methods are up to the audit team. Automatic and manual controls are usually used. • Create a draft report with errors found and submit it to the project team for correction. • A final report is issued, taking into account all actions taken by the team to address the issues identified. • gas efficiency

6. Smart Contract Vulnerability • Most audits involve checking contracts for security vulnerabilities. While some problems are superficial, many bugs in bsc smart contract auditing can only be fixed with the help of sophisticated tools and strategies. • For example, weak smart contracts combined with market manipulation could be vulnerable to flash loans. • To detect these issues, auditors try to break contracts and simulate hacking. Common vulnerabilities include: • Recursive call: A smart contract calls another external contract before committing changes. After that, the external contract can recursively interact with the original smart contract in an invalid way because its balance has not yet been updated.

7. Platform Security Vulnerabilities • Most audits involve examining the network using the smart contracts hosted on it and the APIs used to interact with the DApp. • If the project is vulnerable to DDoS attacks or the interface is compromised, users run the risk of connecting their wallets to malicious blockchain applications. In conclusion • Fortunately for investors and users, smart contract auditing has become the gold standard. On the other hand, when most projects are audited, it becomes increasingly difficult to judge their value, so it is important that you read the audit firm's report yourself. Even if you're not tech-savvy, you can read the feedback and the severity of potential problems.
