Crate palinurus_core 

Palinurus — minimal wasm32-wasip2-friendly Solana substrate for ZeroClaw WIT tool plugins.

Track C (DePIN) core for the Superteam Brasil × ZeroClaw bounty. MIT-licensed. Pure logic, no wasm dependency — host-testable with cargo test; the plugins import this as a crates.io dependency and compile it into their wasm32-wasip2 components.

solana-sdk / solana-program cannot be compiled inside a WIT component (they pull in syscall stubs that don’t build for wasm32-wasip2). This crate hand-rolls only the primitives a Solana tool plugin needs:

• PDA derivation (pda::find_program_address) — reimplementation of solana_program::Pubkey::find_program_address using sha2 + curve25519-dalek.
• (more modules landing as the build progresses: base58, borsh helpers, versioned-tx construction, durable-nonce handling, RPC over the host’s wasi:http, response shaping to ~200 tokens).

Modules

base58

Base58 Pubkey newtype — the typed 32-byte Solana address used across the crate.

borsh

Borsh instruction-data helpers for Solana instructions the Palinurus plugins emit.

durable_nonce

Durable transaction nonces — the blockhash-expiry fix.

pda

Solana Program Derived Address (PDA) derivation.

response

Response shaping — keep RPC/IX outputs to ~200 tokens, not 40KB JSON.

rpc

Solana JSON-RPC 2.0 client over waki (blocking wasi:http).

versioned_tx

Versioned transaction (V0) construction — unsigned, T1 custody.
