Cryptocurrencies have emerged as one of the revolutionary innovations of recent years, and with the current Trump administration in charge, it’s expected to reach the moon. However, the web3 landscape is full of mines. Developers and investors need to be very careful, a single misstep can result in the loss of millions of dollars in the blink of an eye. Similar to the traditional web2 system, a strong cybersecurity strategy is essential to combat sophisticated threats targeting the cryptocurrency ecosystem. From Advanced Persistent Threats (APTs) to vulnerabilities in smart contracts, the risks are real and pervasive.

In this buyer’s guide, we will explore a set of crucial tools that developers can leverage to implement a comprehensive cybersecurity strategy. These tools will help identify vulnerabilities, monitor networks, and safeguard digital assets, ensuring the integrity of blockchain projects and protecting against malicious attacks.

1.Smart Contract Auditing Tools

Smart contracts work by executing contracts based on the terms written in code. They are the backbone of the decentralized applications across various sectors and play a vital role in blockchain networks like Ethereum. As everyone knows, smart contracts are immutable, but once they are deployed, any vulnerabilities in the code can have serious consequences, leading to millions of dollars in losses.

MythX

Mythx is one of the powerful cloud-based smart contract auditing tools by ConsenSys. Web3 developers can integrate MythX with popular IDEs like Remix, Truffle, and VSCode to improve the security pipeline before deploying smart contracts into EVM chains. It is specially designed for Ethereum smart contracts. 

Slither

Slither is an automated auditing tool based on a solidity static analysis framework designed using Python. Slither can integrated into your CI/CD pipeline and works with Truffle, Hardhat, and others. Developers can interact with Slither through API, and its average execution time is less than 1 second per contract. Moreover, many web3 developers mentioned that it generates fewer false positives compared to other tools in the market. 

Certik

Certik is another industry-recognized player in this space, offering both automated and manual security audits. Certik’s platforms use AI to monitor and secure blockchain protocols. Certik utilizes mathematical proof to validate the correctness of smart contract code for securing the blockchain.

2.Blockchain Vulnerability Scanning Tools

Blockchain networks, by their nature, its strong and secure, but they are not immune to attacks. One notable and dangerous is the 51% attack, where a malicious actor gains the majority of the network’s computing power. Using this power, the attacker can reverse transactions that break the integrity of the network or mining hash rate. In 51% attacks, the attacker can reverse the transaction, undermining its integrity. 

While 51% attacks are rare in established blockchains with with significant mining power, smaller, less-secure networks remain at risk. This necessitates the constant scanning and monitoring of blockchain networks.

Oyente

Oyente is a smart contract analysis tool that can identify and mitigate vulnerabilities in Ethereum contracts and EVM bytecode. It was developed by researchers from the National University of Singapore in 2016. Oyenete was able to detect the DAO bug, which caused more than 60 million dollars in loss for investors in 2016.

SolidityScan

SolidityScan is one of the popular automated smart-contract vulnerability scanners available in the market. It uses AI to improve vulnerability detection in the web3 ecosystem. SolidityScan supports Ethereum, Polygon, Avalanche, Binance, and more. It also provides suggestions to speed up the remediation process.

3.Blockchain Penetration Testing

Blockchain penetration testing is a simulated attack on the web3 platform to detect vulnerabilities. It helps developers to assess the strength of your web3 application’s security. In the market, automated tools and manual testing options are available. 

Immunefi

 A bug bounty platform similar to Hackerone that connects web3 developers with ethical hackers. Web3 companies could use this platform to identify vulnerabilities.

3.Wallet Security

When it comes to securing cryptocurrencies, storing them in a secure wallet is critical. Hot wallets (connected to the internet) are less secure and vulnerable to cyber attacks, while cold wallets (offline) but challenging to connect to sometimes. For web3 companies and developers, securing the hot wallet is critical. Here are some of the tools that can implemented in your web3 platform to secure your user’s hot wallet.

Honeypot. Is

It is a tool that detects whether the smart contract you interacting with is a honeypot or not. This tool simulates a transaction to determine the nature of the smart contract. Implementing this tool can save your users from scams and theft.

Trezor Model T

Trezor Model T is one of the popular hardware wallets (cold wallet) that supports a wide range of cryptocurrencies. With a touch screen and secure PIN code, it offers strong security to cryptocurrency investors. Trezor also offers wallet backup when your device is lost. This wallet can store 14 cryptocurrencies, including well-known Bitcoin, Ethereum, and Doge. 

4.Multi-Signature Solutions

Multi-signature(multi-sig) is a type of wallet that requires multiple private keys at once to approve a transaction by spreading the risk across multiple parties. Even if one key is compromised, the wallet remains secure. This type of wallet is perfect for companies, crypto funds, and large-scale investors who want to mitigate the risk of theft of private keys.

Gnosis Safe

Gnosis Safe is one of the highly regarded multi-signature used by seasoned institutional investors and DAOs. It allows users to set their own multi-signature configurations, making sure that transactions are only authorized based on a predefined set of keys. Gnosis Safe is suited for individuals and web3 companies who are looking to secure their crypto assets from unauthorized access and security incidents. It also supports tokens and NFTs.

BitGo

Bitgo is one of the leaders in the web3 domain, offering multi-signature wallets for web3 businesses and institutional investors. It provides a secure environment with features like spending limit and multi-user access. Bitgo offers multi-signature wallets for accounts for Ethereum and other programmable blockchains.

Conclusion

The web3 domain offers more opportunities compared to other domains, but it comes with significant risks. Cyberattacks, scams, and vulnerabilities are constant threats, but with proper security tools and strategy, developers can protect their users and assets.

From smart contract auditing tools to storage solutions, this buyer’s guide offers a set of tools to keep your web3 company cybersecurity strategy futureproof. Integrating these above-mentioned tools in your web3 development will save you from the upcoming modern threats.
