Juicebox V5 Suckers - Cross-Chain Token Bridging

Problem

Bridging project tokens between chains while maintaining their proportional treasury backing requires understanding a complex three-phase protocol with merkle proofs, chain-specific AMBs, and careful state management.

Context / Trigger Conditions

Apply this knowledge when:

• Building cross-chain bridging UIs
• Encoding prepare(), toRemote(), or claim() transactions
• Querying pending/claimable bridge transactions
• Fetching merkle proofs from Juicerkle
• Understanding why a bridge is "stuck" in pending state
• Implementing emergency exit flows
• Working with JBSuckerRegistry to find bridge routes
