Crate sc_hop 

sc-hop — Hand-Off Protocol

Node-level ephemeral disk-backed data pool for Substrate collators, with an RPC for submit/claim/ack, best-effort on-chain promotion, per-account rate limiting, and graceful degradation when the runtime lacks HopRuntimeApi.

See the crate README for the design overview, integration guide, CLI flags, RPC reference, and error codes.
