hopper-sdk

v0.2.1crates.io· Rust

Off-chain SDK for the Hopper zero-copy state framework. Parses receipts, decodes account state through segment-aware partial reads, builds instructions from a ProgramManifest, and narrates state diffs for indexers and explorers. Neither Pinocchio, Anchor zero-copy, nor Quasar ships a symmetric off-chain SDK of this shape. Hopper does because Hopper owns the layout_id fingerprint, segment roles, receipt wire format, and policy graph on both sides of the program boundary.
