🛡️ Intent Firewall

Read what you're about to sign. Paste a NEAR Intents payload — the exact message your wallet asks you to sign — and see what it really does before your signature exists.

Built for NEAR HACKATHON · Track: AI Security & Defense

What this checks

Decoding (incl. NEP-413 wrappers) · deadline sanity · bundled withdrawals and extra intents hiding inside a “swap” · unknown / unlisted assets · value in vs value out at live registry prices · cross-checks against the quote you were shown (wrong asset, wrong amount, below the guaranteed minimum, embedded app fees). This is a structure-and-economics check — it does not verify the signature itself, and it never asks for your keys. Everything runs locally in your browser; prices come from the public 1Click token list.
