ShieldAI Transaction Firewall is a free Chrome add-on designed to bolster security for users engaging in blockchain transactions. This tool provides real-time analysis of transactions initiated in Web3 applications, assessing the risk associated with each transaction before wallet confirmation. It categorizes risks into four verdicts: SAFE, CAUTION, HIGH RISK, and BLOCK RECOMMENDED, allowing users to make informed decisions. Additionally, it offers a plain-English explanation of potential transaction impacts, along with a breakdown of threat signals and a safety score.

One of the standout features of ShieldAI is its capability to store local scan history within the browser, ensuring privacy by not collecting sensitive information such as private keys, seed phrases, or passwords. The tool only transmits transaction metadata for analysis, and users can configure the API endpoint at runtime for added security. ShieldAI is ideal for those seeking greater awareness of risks in the evolving landscape of Web3 transactions.
