Smart contract vulnerability and exploitation has been a dark whisper among crypto enthusiasts for some time. The DAO hack to wormhole attacks and other DeFi bridge attacks, made the decentralized world confused!
Being popular in security, blockchain technology has been adapted by a lot of users. Though smart contracts are deployed over blockchain, they are not without risks.
An auditing is the last thing a smart contract may need before deploying into blockchain to enhance code correctness for optimized performance.
Let’s go through few most asked doubts about smart contract auditing.
What is a Smart Contract Auditing?
The foremost aspect of understanding the smart contract auditing process is its definition. The audit process for a smart contract focuses on scrutiny of the code used for underwriting the terms and conditions in the smart contract. With the help of such an audit, smart contract developers could easily identify the vulnerabilities and bugs before the deployment of smart contracts.
Generally, third-party entities carry out smart contract audits to ensure a thorough review of the code. On the other hand, enterprises can choose professional, smart contract auditors for carrying out the audit process.
Why are Smart Contract Audits are important?
It is quite important to test the code thoroughly before deploying the smart contract. Once you write the smart contract to the blockchain, it is impossible to change the code. Deploying smart contracts without proper audits could result in untoward circumstances such as discrepancies in the desired performance of the contract. At the same time, inadequate audit processes could also land you up with risks such as loss of personal data or data theft.
There are few more factors to do an audit !
- An audit provides an extra layer of security to a smart contract.
- This helps in enhancing investors trust in that particular project.
- Optimizes code functionality.
- Impart protection against thefts and hacks.
How do Smart Contract Audits work?
Gathering Information
It helps to define the audit scope, expected business behavior, project’s goal, and architecture. Auditors must be able to access documents such as the whitepaper, the business logic, the technical documentation, etc.
Module Tests
The auditor runs analysis and scans on the code line-by-line to find out vulnerabilities. This is called manual testing, although automated audit tools usually accompany it for speedy and thorough verification of the smart contract.
Results for refactoring
The auditor provides an initial report with detailed results and recommendations, and after refactoring the code, a final report will be issued after postcode refactoring and final analysis.
Can I conduct a smart contract audit myself?
It is possible for one to conduct a smart contract audit.
One must be aware of common smart contract vulnerabilities, but it is still recommended that you get your code audited by dedicated and experienced security auditor.
Out-sourcing the audit process to a third party provides a different dimension to your smart contract. External auditing imparts an unbiased view of the project and significantly reduces the chances of hacking.
What are Smart Contract Security risks?
Smart contract flaws could pose a security risk and are tempting targets for malicious cyber criminals. In fact, if there are no external exploiters, there is a risk of capital collapse and financial losses in some cases.
Here are a few vulnerabilities commonly observed in smart contracts.
1. Re-Entrancy
2. Broken access control
3. Front running
4. Floating Pragma
5. Arithmetic Over/Under Flows
6. Unexpected Ether
7. Delegate call
8. Entropy Illusion
9. Short Address/Parameter Attack
10. Unchecked CALL Return Values
11. Denial Of Service (DOS)
12. Block Timestamp Manipulation and many more.
In fact, new vulnerabilities enter the ecosystem always and then, making it imperative to go for periodic smart contract audits.
