Bridge Integration

MPC signing for cross-chain bridge transfers

The Lux Bridge uses MPC for threshold signing of cross-chain transfers. Each bridge transaction requires t-of-n MPC nodes to produce a valid signature.

Flow

  1. User initiates transfer via Bridge UI
  2. Bridge API validates and creates intent
  3. MPC nodes receive signing request via NATS
  4. Each node produces a threshold signature share
  5. Shares are aggregated into a valid signature
  6. Transaction is broadcast to the destination chain
