Overview

Real-time transaction firewall for EVM wallets

Sentinel is a transaction firewall that sits between dApps and your wallet. It intercepts every transaction, decodes it into plain English, scores the risk, and blocks dangerous approvals, Permit2 phishing, and scam contracts before your wallet signs. Works with MetaMask, Rabby, and any EVM wallet.
