Anchor

Anchor is a development framework for building secure Solana programs, also known as smart contracts. Described as a leading framework for Solana development, it is designed to help developers create production-ready applications more efficiently while reducing potential vulnerabilities through built-in security features. Anchor supports key stages of the development process, including writing, testing, deploying, and interacting with programs.

The Anchor documentation guides developers through installation and local environment setup, as well as a quickstart for building their first program. Those who prefer to begin without installing tools can use the browser-based Solana Playground. The framework’s resources also cover program structure, account types and constraints, program-derived addresses, cross-program invocation, and interface definition language files. Additional documentation addresses client libraries, testing tools, SPL token interactions, custom errors, events, verifiable builds, and security considerations such as Sealevel attacks. Anchor provides a command-line interface and links to its GitHub repository and developer communities on Discord and Stack Exchange.
