Cross-chain Message Demo
Watch how bridges securely ferry messages and tokens between blockchains — step by step, in real time.
Configure your cross-chain message above
Choose a source chain, destination chain, bridge protocol, and payload — then hit Send Message to watch the full journey unfold.
Source chain emits
Your dApp calls a bridge contract on the source chain. It locks or burns tokens and fires an on-chain event with the encoded payload.
Off-chain relay picks up
Watchers (relayers, oracles, validators, or guardians depending on the protocol) listen for the event and prepare to carry it across.
Proof or consensus
The relay proves the message is valid — via DVN signatures, a Merkle proof, light-client verification, or an optimistic fraud window.
Destination executes
Once verified, the bridge contract on the destination chain mints, unlocks, or calls your target contract — completing the message journey.
