Embed transaction intelligence in your wallet
Use Case
Add Transaction Intelligence to Your Wallet
Your users shouldn't sign transactions they don't understand. EthIntel's API, widget, and Snap make every transaction readable.
Embeddable Widget (27KB)
Drop a single script tag to show transaction explanations anywhere. Self-contained with Shadow DOM — no CSS conflicts. Supports light/dark themes and all 8 chains.
REST API (26 Endpoints)
Full JSON API with SSE streaming for real-time decode progress. Explain transactions, profile addresses, simulate before signing, assess risk — all in one API.
Pre-Signing Simulation
POST /api/scan with the raw transaction before the user signs. Get back a plain-English summary + safety score + risk signals. Show users what they're about to approve.
MetaMask Snap
Transaction insight panel that shows explanations + safety scoring before every signature. Works with onTransaction and onSignature hooks.
