  • De.Fi has launched its crypto antivirus that detects phishing attacks, smart contract vulnerabilities, and other exploits.
  • De.Fi Antivirus is now available on Polygon.
  • The antivirus is free and accessible to all.

Crypto is full of scammers and grifters, often tricking users into sending them their digital assets or unknowingly granting access to their wallets and other apps they use.

However, solutions like crypto antiviruses now allow users to minimize the risk of getting scammed.

De.Fi Launches Crypto Antivirus on Polygon

De.Fi, a leading Web3 app for asset management, announced today the integration of De.Fi Antivirus on Polygon.


The De.Fi Antivirus features a suite of tools that protect users against typical harmful crypto exploits such as phishing, smart contract vulnerabilities, blind signing, among others.

Powered by machine learning algorithms and trained by smart contract auditors over the past two years, De.Fi Antivirus can identify and inform users of potential malicious exploits and vulnerabilities they might be exposed to. De.Fi’s suite of digital asset management tools is already trusted by researchers at companies like Coingecko, as well as academic institutions such as the University of London and the National University of Singapore.

Polygon is home to some of the biggest Web3 projects such as Aave, Uniswap, OpenSea and one of the most popular gateway for direct-to-consumer applications in Web3, including for enterprises like Starbucks, Reddit, Adidas, DraftKings and more. With De.Fi Antivirus, all Polygon ecosystem users can enjoy a comprehensive suite of user-friendly security tools to safeguard their digital assets.


Hamzah Khan, Head of DeFi at Polygon Labs, said the new antivirus will add a “layer of protection against harmful crypto exploits.”

“We are thrilled De.Fi is bringing their powerful suite of security tools to the Polygon ecosystem. The De.Fi Antivirus will provide users with an added layer of protection against harmful crypto exploits, ultimately elevating the standard for Web3 security.”

Scanning for Smart Contract Vulnerabilities

One of De.Fi Antivirus’ features is the De.Fi Scanner, a one-click due diligence tool that can prevent users from interacting with potentially malicious or exploitable assets. By inserting the smart contract address of a token, an NFT, or a dApp built on Polygon, the Scanner provides a comprehensive audit that highlights the contract’s safety, high-risk functions, liquidity, and token distribution analysis. 

Additionally, the De.Fi Shield can analyze the user’s wallet and the smart contracts they interacted with in the past. It provides personal risk ratings on signed transactions and enables instant revocation of risky approvals for any Polygon transaction.

Artem Bondarenko, Software Architect at De.Fi, said that the best part about De.Fi’s new antivirus is that it’s free and easily accessible to all.

“At De.Fi, we're thrilled to contribute to the safety of the vibrant Polygon ecosystem with our user-friendly security tools. Our goal is to provide a layer of protection for anyone interacting with web3 applications and tokens, giving them peace of mind. And the best part? Our tools are free and easily accessible to all.”

On the Flipside

  • As with any antivirus, users should always do their own research before deciding whether to use it or not as it may contain bugs or collect data.

Why This Matters

Crypto users can now avoid getting scammed or phished by checking the smart contracts they interact with, among other things.
