wormhole
Skill is based on Wormhole (reference implementation) at commit 612caaa, generated 2026-02-24.
Wormhole is a generic cross-chain messaging protocol: guardians observe finalized messages on connected chains, reach consensus, and produce Signed VAAs. Applications (Token Bridge, NFT Bridge, oracles) sit on top; the core does not hold assets or deliver messages. Use this skill to integrate contracts with the core bridge and Token Bridge, operate or reason about guardian nodes, and use Cross Chain Queries (CCQ).
