Sign a transaction with MetaMask, watch ShieldTrade decide.

Connect your MetaMask wallet pointed at the active demo chain. Pick a scenario below. MetaMask will sign the EVM transaction locally in your browser; the demo then forwards the same transaction fields to the live Gateway, which runs capability resolution, the EVM simulator, the risk engine, and policy — and returns the same ALLOW / BLOCK / WARN / CHALLENGE / REVIEW verdict a real tenant would receive.

Connect MetaMask and pick a scenario to see the live decision.

What you are looking at

Sign with your wallet on the active demo chain.

Decision is the only authoritative output. It is set by Hard Gate 2 (deterministic) and Tenant Policy.
Risk Assessment is advisory. It cannot authorize or deny. The demo includes it so you can see how a HIGH/CRITICAL risk level coexists with an ALLOW decision.
Hard Gate 2 BLOCK cannot be overridden by risk, ML, or operator approval. The BLOCK scenario demonstrates this fail-closed behavior.
Signing stays in your wallet. The demo server never sees the private key — it only forwards the fields MetaMask already signed.
