What Are the Risks of Web3?
Before learning about security audits in web3 the first question in your mind is the security risks in web3. For starters, it’s more secure than web2 due to some basic principles.
However, web3 security challenges arise from a variety of factors, including integration mechanisms between web3 and web2 architectures.
On the other hand, some security issues may arise from the functionality of blockchain, smart contracts, IPFS, and other Web3 components.
Furthermore, the web3 network relies on communication, creating problems for timely error resolution. Here is an outline of the most common security risks in the web3 domain.
No encryption and no authentication for API queries
Web3 applications must rely on API prompts and responses, which do not guarantee authentication from connection endpoints.
It is important to understand that web3 is fully decentralized and front-ends still rely on web2 technologies for easy integration for user endpoints.
As most Web3 API queries do not contain cryptographic signatures, they are subject to data interception, attacks along the way, and many other security risks.
Decentralized storage systems are not isolated
The most distinctive feature of web3 is decentralization, meaning that any connected node can store and access data on the blockchain.
Given the nature of data stored in decentralized storage systems, you should recognize the importance of a web3 security audit to address many privacy and security issues.
Research shows that data anonymity is a myth.

Importance of Web3 Security Audits
The top web3 security risks show that security issues in web3 pose significant challenges to web3 adoption. Why do businesses rely on web3 solutions when they lose millions due to web3 security risks?
On the other hand, Web3 security audit best practices help identify security problems before they cause any harm. Web3 has the potential to offer consumers the most powerful ‘next Internet’.
However, web3 security risks can create challenges for businesses and consumers that adopt web3 solutions.
Among the most popular ways businesses use Web3 are decentralized applications and DeFi. In addition, decentralized storage systems are also emerging as promising web3 use cases for businesses.
Considering the value of blockchain, smart contracts, dApps, and DeFi solutions, it is important to make a start on web3 solutions to protect against security risks. Security audits not only help identify potential vulnerabilities or errors but also help fix security issues faster.
Best Practices for Web3 Security Checks
“What is web3 auditing?” You may be surprised at the answers. Before getting into the best practices. Web3 auditing refers to a set of procedures performed to inspect a web3 system or application before it is deployed. Interestingly, you cannot complete the security check for web3 in one step.
At the same time, you need to follow some precautions and tips to get the desired result without interruption. Best practices help improve the security of Web3 applications and mitigate risks with smart contracts.
Let’s look at best practices for Web3 auditing at various stages of the audit process.
Before Preparing the Audit
Before starting a web3 audit, it is important to review a web3 security audit example and follow best practices in your inferences.
Prior audit preparation is essential to ensure an effective and efficient audit. Here are some notable best practices in the pre-audit preparation phase.
Familiarize yourself with smart contract functionalities
First, you need to understand the functionality and purpose of a smart contract along with the desired use cases.
You should thoroughly review the specifications, documentation, and requirements of the smart contract.
This will help you gain a deeper understanding of the desired functionality of the web3 solution.
Design and Architecture Review
The next step in a Web3 security audit focuses on a comprehensive review of the design and architecture of the smart contracts that power the Web3 solution. It helps you identify potential vulnerabilities and design flaws in a smart contract for a web3 application.
You should consider things like access control mechanisms, contract structure, data flow, and contract interactions.
It is also important to ensure the performance of the smart contract by established guidelines, performance standards, and best practices.
Collection of important information
The web3 audit process also includes gathering relevant information about the smart contract. Examples of important information required for a web3 security audit checklist include the contract’s ABI, source code, contract address, and assembled bytecode.
ABI serves as a critical tool to support interactions between a Web3 application and a smart contract.
Knowledge of the deployment environment
You can improve the web3 audit process by understanding the deployment environment during the initial audit preparation phase.
A Web3 application’s deployment environment includes a blockchain platform, appropriate protocols, and a preferred network for deployment.
Monitoring the deployment environment for a web3 application helps identify web3 security issues in a specific context. During deployment, you need to know important technical details and limitations.
Set clear audit objectives
One of the most important best practices for web3 auditing is setting clear goals. Web3 audits without clearly defined scopes usually end up with incorrect results.
On the other hand, best practices of web3 security auditing further emphasize the need to define the scope of web3 auditing.
A scope can define specific roles, contracts, and areas of a web3 application that should be subject to audits.
In addition, you must define the audit objectives, timeline, and deliverables together with the contracting team. It is also important to identify guidelines for communication, communication styles, and communication channels.
Review the contract
The second step of the web3 security audit process deals with contract review, which is the most important part of the audit.
The Contract view provides a comprehensive overview of the source code and smart contract that power a Web3 application.
With a thorough inspection, you can review the assessment of the overall security posture as well as find possible vulnerabilities.
Here are some of the most popular best practices in contract review for web3 applications.
Follow Security Best Practices
It is important to follow the important guidelines for creating smart contracts and fulfill the established best practices for web3 security.
For example, you must follow important safety aspects for solidity contracts.
Any web3 security audit example shows how Solidity’s security checks can help detect common security flaws such as access control issues, re-access, and integrity compliance or errors.
Verify the Security Data Policy
The Web3 audit process improves information management security. You should look at how a smart contract handles sensitive data, including external dependencies, user data, and contract state variables.
Also, it is important to review the agreement for data sanitization, secure storage practices, and data leak prevention.
Check External Dependencies
An assessment of web3 security auditing may also involve examining external dependencies such as oracles, libraries, and APIs.
It is important to ensure that all dependencies are backed up, updated, and audited to minimize potential exploits or vulnerabilities.
You should also validate smart contract interactions with external contracts and ensure validation and authentication of external contracts.
On top of that, the audit should ensure that the agreement also leverages security mechanisms to facilitate smooth interactions.
Check event logging and debugging methods
A key best practice for web3 auditing during the contract review phase focuses on event logging and review methods for error correction.
Auditors should follow a proper web3 security audit checklist to see if web3 application procedures for debugging are documented and detailed and required for auditing.
Additionally, auditors should consider robust debugging to help prevent unexpected adverse events or errors.
