Cross-Chain Bridge Network

Shared-L2 · hub & spoke

One Panda L2, 6 chains. Deposits are locked on each spoke and credited 1:1 to the shared L2; cross-chain messages route hub↔spoke by rollupId; each spoke settles its own batches. The relayer is a single N-chain process.

How it flows
  1. User deposits on a spoke → locked in PandaBridge.
  2. Relayer credits the shared L2 BridgeBalance (Invariant A).
  3. Messages route hub↔spoke by rollupId (isolated).
  4. Each spoke settles its own batches via PandaVerifier (Invariant B).
