“Our platform leverages advanced machine learning algorithms to evaluate every transaction in real-time. In addition to detecting threats and sending alerts, it enables companies deploying smart contracts to block malicious transactions in real-time so they never have to pause their web3 applications,” added Gravrock.

The tool has now been upgraded to include malicious URL data, enabling it to flag the latest types of threats and smart contract scanners, a representative told CoinDesk on Tuesday.
