SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Anchor-based Solana development can be complex and error-prone. This Skill provides a structured guide for building secure, maintainable programs with Anchor, covering account validation patterns, security best practices, and cross-program invocation (CPI) strategies.

Core Features & Use Cases

  • Declarative account management and IDL generation for Solana programs.
  • Security-focused patterns: account constraints, PDA bumps, and signer verification.
  • Testing and deployment workflows with Mollusk or LiteSVM, plus TypeScript client generation.
  • Practical examples for common tasks: program scaffolding, CPI interactions, and upgrades.

Quick Start

Create a minimal Anchor program skeleton that initializes a protected account with proper validation and demonstrates a CPI interaction.

FAQPage Schema
How do I write secure Solana programs with Anchor?

Secure Anchor programs require account validation patterns, PDA bumps, and signer verification. This Skill covers declarative account management, security constraints, and best practices for preventing common vulnerabilities in Solana program development.

What's the best way to test Anchor-based Solana programs?

Testing Anchor programs uses Mollusk or LiteSVM frameworks to simulate on-chain behavior. This Skill provides testing workflows, account setup patterns, and validation strategies for end-to-end program verification.

How do I implement cross-program invocations (CPI) in Anchor?

CPI in Anchor requires proper account passing, signer delegation, and instruction marshaling. This Skill demonstrates CPI patterns, security considerations, and practical examples for calling other Solana programs safely.

Can I generate TypeScript clients automatically from my Anchor program?

Anchor generates IDL (Interface Definition Language) files that automatically produce TypeScript clients. This Skill covers IDL generation, client code creation, and integration patterns for end-to-end program development.

What account validation patterns should I use in Anchor?

Anchor enforces account validation through declarative constraints: ownership checks, mutability flags, signer verification, and rent exemption. This Skill details constraint syntax, validation workflows, and security implications for each pattern.

How do I handle program upgrades and deployment with Anchor?

Anchor deployment workflows cover program initialization, upgradeable program patterns, and state migrations. This Skill provides deployment strategies, IDL management, and best practices for maintaining live programs.
