The Bridge Guardian gates withdrawals on a cross-chain bridge. Load any of the three preset attack shapes (Ronin, Wormhole, Nomad), try to release, and read the verdict. A naive bridge would have paid out on each one.

Pulled from Across Protocol, the intent-based bridge that fills cross-chain transfers on Base. Each row is a real fill that already landed. Click one to load it into the review pipeline above; the agent will read the fill (origin chain, amount, recipient) and decide whether it looks suspicious. Same flow as the synthetic presets.
