Practical overview

When it fits

Use Chio when starting or managing a Solana Pinocchio program and you want CLI support for scaffolding and common development tasks.

Who it is for

  • Solana developers building programs with Pinocchio.
  • Rust developers who want a CLI scaffold and project-task commands for Pinocchio development.
  • Teams generating IDLs or TypeScript clients from Pinocchio programs.

Documented uses

  • Create a Pinocchio project with a prebuilt directory structure and test setup.
  • Build, test, and deploy a Solana program from the command line.
  • Generate a keypair or synchronize the deployment keypair with the declared program ID.
  • Extract a program IDL or generate a TypeScript client.
Before you choose

Requirements & limits

Chio is an open-source Rust CLI available from its public GitHub repository under the Apache-2.0 license.

  • The tool is specific to Solana Pinocchio project development.
  • Project initialization uses Mollusk tests by default and supports LiteSVM as an alternative.
  • The TypeScript client flow uses Shank, Codama, and Bun.
  • The documented setup requires Rust and Cargo; development setup also lists Solana CLI tools.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
