Sigil - Web3 Trust Layer

Real-time transaction risk analysis. Understand what you're signing before you sign it.

Sigil helps you understand Web3 wallet requests before you approve them. Every day, crypto users sign transactions, approvals, and messages they barely have time to inspect. Sigil adds a clear security layer between the dApp and your wallet, reviewing signing requests in real time and translating risk into plain English. Before a supported wallet request continues, Sigil shows a simple verdict: Safe, Caution, or Dangerous. You also get a 0-100 risk score, key warnings, and a link to a full Sigil analysis when deeper review is available. Sigil can help identify risky token approvals, suspicious contract interactions, typed-data signatures, and other signing flows that deserve a second look. It is built for daily crypto use: lightweight, practical, and focused on helping you pause before making an irreversible on-chain decision. Features: - Real-time wallet request review - Unlimited approval detection - Typed-data and signing prompt checks - Plain-English risk verdicts - 0-100 risk scoring - Quiet, Standard, and Strict protection modes - Trusted sites and trusted contracts - Local recent-check history - Full analysis links through Sigil’s Web3 Trust Layer Sigil is not a wallet, exchange, or financial adviser. It does not sign transactions for you and it cannot guarantee that every risk will be detected. It gives you clearer context so you can make better decisions before you sign.
