SentinelAI protects your wallet from malicious approvals, phishing contracts, and hidden transaction risks before you sign.
SentinelAI works automatically in the background — decoding and scoring every signature before it reaches your wallet.
Every site is checked against live phishing & typosquat blocklists (MetaMask + ScamSniffer) in real time.
The instant a dApp asks you to sign, SentinelAI pauses the request — before your wallet ever opens.
Raw calldata is decoded to plain English — 4byte signatures + AWS Bedrock AI explain exactly what you're signing.
Simulation, threat intelligence, and approval analysis produce a 0–100 risk score with clear reasons.
A clear verdict with Reject or Proceed. SentinelAI never auto-signs — you always make the final call.
The same Guardian engine that powers the overlay also runs continuously in the background.
Over $180M in assets protected. Here's what our users say.
“SentinelAI caught a malicious Uniswap clone approval that would have drained my entire USDC balance. The AI explanation made it crystal clear why it was dangerous.”
“The approval scanner showed me 47 unlimited approvals I had no idea about from old dApps. One-click revoke saved me hours and probably saved my wallet.”
“I use the Transaction Simulator before every major interaction. It's like having a security audit on-demand. The risk score meter is incredibly accurate.”
“The Threat Intelligence feed alerted me about a fake Aave deployment 3 hours before it was listed on any other security site. Real-time is not an exaggeration.”
“Went from anxious every time I sign a transaction to completely confident. The AI Copilot explains contract interactions in plain English — no more guessing.”
“We mandate SentinelAI for every wallet in our fund. The wallet health score gives our compliance team a single number to track. Absolutely essential tool.”
