hopper-sdk vs jiminy vs jiminy-core
Side-by-side comparison of Rust crates
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.
The zero-copy standard library for Solana programs built on Hopper Runtime. Account layout, validation, PDA, Token/Mint readers, Token-2022 screening, CPI guards, DeFi math, AMM, slippage, lending, staking, vesting, multisig, distribution, Merkle, Ed25519, Pyth oracle. Declarative macros for error codes, instruction dispatch, and account checks. no_std, no_alloc, no proc macros, BPF-safe.
Core systems layer for Jiminy: account layout, zero-copy IO, validation, PDA, sysvar access, math, time checks. Declarative macros for error codes, instruction dispatch, and account uniqueness. no_std, no_alloc, no proc macros, BPF-safe.
