Cross-chain message

A message submitted on one chain for authenticated delivery and execution on another.

In plain language

For the Vara–Ethereum bridge, Vara-side submission, relayer delivery, Ethereum execution and Ethereum finality are separate stages.

Why it matters

Source-chain success proves only the stages visible on that source unless destination evidence is attached.
