ShieldAI Transaction Firewall

ShieldAI intercepts malicious crypto transactions before your wallet signs them. Real-time phishing detection, AI risk scoring, and asset simulation on BNB Chain. What ShieldAI does Most security tools tell you what happened after you lost funds. ShieldAI intercepts the transaction at the source by hooking eth_sendTransaction in the page context before your wallet ever sees the signature request. Every transaction gets a ShieldScore (0–100) based on: Contract bytecode fingerprinting (honeypot and rug pull patterns) Deployer wallet history and cluster analysis Tenderly pre-execution simulation showing exact asset deltas before you sign EIP-712 permit and Permit2 signature analysis Phishing site detection powered by GoPlus Security threat intelligence If the score is high risk, ShieldAI blocks the transaction and shows you a plain-English explanation of why — not just a red flag, but a sentence like: "This contract has a hidden mint function. The deployer wallet launched 3 similar tokens in the past 30 days, all drained within 48 hours." Key protections Honeypot detection — identifies contracts that let you buy but block sells Rug pull pattern matching — bytecode and deployer cluster cross-reference Wallet drainer interception — blocks Permit2 and approval exploits before signing Phishing site firewall — flags known malicious DApp URLs in real time Transaction simulation — shows you what assets will leave your wallet before you sign Wallet health scanner — surfaces high-risk open approvals Technical specification Manifest V3 service worker architecture Permissions used: storage (settings + scan history), host_permissions (phishing URL checks and API calls) All transaction data encrypted in transit via HTTPS/TLS Scan history stored locally — never uploaded Privacy policy: https://shieldbotsecurity.online/privacy.html Who builds this ShieldBot Security — open source on GitHub, active on BNB Chain ecosystem.
