What's Pinocchio?

Zero-dependency, no-std entrypoint. No codegen, no IDL — the developer hand-writes account parsing against the raw C ABI (sol_invoke_signed_c).

Tiny binary and low compute-unit cost, at the price of manual safety and no self-description. The choice for a hot path — routing, MEV, high-frequency — where every CU and lamport of rent is optimized.

Built by Anza (the Agave client team).

What it is

A drop-in replacement for the solana-program crate — not an Anchor-style framework. Its core innovation is zero-copy AccountInfo: instead of deserializing account data into an owned struct, it returns a pointer directly into the input buffer, eliminating a major class of memory copies and cutting CU usage on hot instructions. It has zero external dependencies and is no_std. It's completely unopinionated — no IDL, no account-validation helpers, no standard layout — so you bring Shank + Codama to generate IDLs and clients yourself. Still unaudited and not at full feature parity with solana-program.

When to pick it

Programs that process enormous volume where CU cost is the bottleneck — token programs, AMM hot paths, Ore-style mining. Not beginner-friendly.

How it looks on-chain

No enforced discriminator or account layout, and no on-chain IDL — so it can't be positively identified from account data. The tiny, dependency-free binary is the main tell, which is why we label it 'inferred'.

Others in the wild: Steel (Ore team — near-native performance on solana-program), Seahorse (Python → Anchor), and Poseidon & Quasar (TypeScript → Rust). Transpilers inherit their lowering target's fingerprint: a Quasar or Poseidon program that compiles down to Anchor will look like Anchor on-chain — discriminators and all.
