Crates#

This page lists every crate under crates/. All of them are off-chain client code. For on-chain programs, use Pina or the official Solana program libraries. Each crate's README has the exact API surface, and the parity ledgers record how much of the reference each one covers.

Release status at a glance#

No SDK implementation crate has been released to crates.io. Every crate below except the umbrella is at workspace version 0.1.0 and is consumed as a git dependency (see Installation).
Most crate names are reserved on crates.io with 0.0.0 placeholders that contain no SDK APIs. solana_kit_jupiter, solana_kit_sns, solana_kit_dapp_publisher and solana_kit_dapp_publisher_cli have no crates.io entry.
The solana_kit umbrella crate (0.0.0) is a published name reservation only. It has no SDK APIs and no dependencies. Do not add it expecting functionality.
The only released artifact is the solana-kit-publisher CLI binary, publisher-cli-v0.1.0 on GitHub Releases (see dApp Store publisher).

The no_std column shows whether the crate root is #![no_std] (with alloc). no_std + alloc is what makes a crate portable across hosts. It does not mean the crate supports on-chain use.

verification/*: private conformance, runtime and boundary harnesses.
tools/: the capability inventory, the Codama renderer and plan checkers.
packages/codama-renderers-rust-solana-kit: an NPM Codama renderer that generates Kit-based Rust program clients.
