Glossary OS

Plain meaning

Start with the shortest useful explanation before going deeper.

A software development strategy where multiple related packages, programs, or applications are stored in a single version-controlled repository. In Solana development, monorepos commonly contain multiple on-chain programs, their test suites, client SDKs, and frontend applications in one repository. Tools like Cargo workspaces (Rust), npm/pnpm workspaces (TypeScript), and Anchor's workspace configuration support monorepo patterns, enabling shared dependencies and atomic cross-package changes.

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

Serialization, memory, data structures, and core engineering basics.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Definition: A software development strategy where multiple related packages, programs, or applications are stored in a single version-controlled repository. In Solana development, monorepos commonly contain multiple on-chain programs, their test suites, client SDKs, and frontend applications in one repository. Tools like Cargo workspaces (Rust), npm/pnpm workspaces (TypeScript), and Anchor's workspace configuration support monorepo patterns, enabling shared dependencies and atomic cross-package changes.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

Anchor.toml

The configuration file at the root of every Anchor project that defines program IDs, cluster endpoints, wallet paths, test scripts, and deployment settings. Key sections include [programs] (mapping program names to pubkeys per cluster), [provider] (default cluster and wallet), [scripts] (custom test commands), and [test] (test framework configuration). Anchor CLI commands read this file to determine build and deployment targets.

Branch

CI/CD (Continuous Integration / Deployment)

Automated pipelines that build, test, and deploy code when changes are pushed. For Solana programs: CI runs `anchor build`, `anchor test`, linting, and security checks. CD automates deployment to devnet/mainnet with multisig approval. GitHub Actions, GitLab CI, and Vercel are common tools. CI/CD catches bugs early and ensures reproducible builds.

Testing (Solana Programs)Solana Verify (solana-verifiable-build)

Open term

Branch

Git

A distributed version control system for tracking code changes across development teams. Essential for Solana development workflows: feature branches for program changes, pull requests for code review, tags for release versions. Solana Verify uses git repos to verify on-chain programs match public source. GitHub hosts most Solana ecosystem repositories.

A JavaScript runtime built on Chrome's V8 engine that enables server-side JavaScript execution. Node.js uses an event-driven, non-blocking I/O model. In the Solana ecosystem, Node.js is used for: running Anchor tests (Mocha/Jest), backend services, transaction bots, indexers, and CLI tools. npm/yarn/pnpm manage JavaScript package dependencies.

Programming Fundamentals

Rust

A systems programming language emphasizing memory safety, zero-cost abstractions, and concurrency without a garbage collector. Rust uses an ownership model with borrow checking at compile time to prevent data races and null pointer bugs. It is the primary language for Solana program development (via Anchor or native solana-program crate) and the Agave validator client.

Programming Fundamentals

TypeScript

A statically typed superset of JavaScript that compiles to plain JavaScript. TypeScript adds type annotations, interfaces, generics, and enums to catch errors at compile time. It is the standard language for Solana client-side development—wallet adapters, dApp frontends, test suites, and SDK interactions (web3.js, Anchor client) are typically written in TypeScript.

Programming Fundamentals

JavaScript

The ubiquitous scripting language for web development, running in browsers and Node.js. JavaScript is dynamically typed and event-driven. Most Solana dApp frontends and scripts use JavaScript/TypeScript with libraries like @solana/web3.js. Node.js enables server-side JS for backend services, indexers, and bot development.
