anchor init / anchor build / anchor test

Anchor CLI commands for project lifecycle. `anchor init <name>` scaffolds a new project (program, tests, Anchor.toml). `anchor build` compiles to SBF and generates the IDL. `anchor test` builds, starts a local validator, deploys, and runs Mocha/Jest tests. `anchor deploy` deploys to the configured cluster. `anchor verify` checks deployed bytecode.

Plain meaning

Start with the shortest useful explanation before going deeper.

Anchor CLI commands for project lifecycle. `anchor init <name>` scaffolds a new project (program, tests, Anchor.toml). `anchor build` compiles to SBF and generates the IDL. `anchor test` builds, starts a local validator, deploys, and runs Mocha/Jest tests. `anchor deploy` deploys to the configured cluster. `anchor verify` checks deployed bytecode.

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 tool or abstraction that removes friction from shipping on Solana.

Technical context

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

Anchor, local validators, explorers, SDKs, and testing workflows.

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.

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 Framework

The most popular framework for building Solana programs in Rust. Anchor provides macros (#[program], #[account], #[derive(Accounts)]) that auto-generate boilerplate for account validation, serialization, discriminators, and error handling. It includes a CLI (anchor init/build/test/deploy), IDL generation, and TypeScript client generation. Reduces program code by ~80% compared to native development.

Branch

Solana CLI

The official command-line tool for interacting with Solana clusters. Key commands: `solana balance`, `solana transfer`, `solana program deploy`, `solana config set --url`, `solana airdrop` (devnet). Configuration in `~/.config/solana/cli/config.yml` sets the default cluster URL and keypair path.

Developer Tools

Anchor v0.31

A major release (March 2025) of the Anchor framework introducing custom discriminators (overriding the default 8-byte discriminator to save transaction space), LazyAccount for on-demand deserialization to reduce compute costs, and stack memory optimizations for init constraints. Positioned as a major milestone on the roadmap toward v1.0.

Developer Tools

#[account] Macro (Anchor)

The Anchor macro applied to structs to define on-chain account data layouts. `#[account]` auto-derives Borsh serialization, adds an 8-byte discriminator prefix (SHA-256 of 'account:<Name>'), and implements space calculation. Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.

Developer Toolscargo-build-sbf

cargo-build-sbf

The Cargo subcommand that compiles Rust programs to Solana Bytecode Format (SBF). It invokes the Solana-specific LLVM toolchain (platform-tools) to produce an ELF binary deployable on-chain. Replaces the older `cargo build-bpf`. Typically invoked via `anchor build` which calls it internally. Output goes to `target/deploy/<name>.so`.

Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.

Developer Tools

#[derive(Accounts)] (Anchor)

The Anchor macro that defines the accounts struct for an instruction. Each field specifies an account with validation constraints. Account types include: `Account<'info, T>` (deserialized), `Signer<'info>` (must sign), `Program<'info, T>` (program reference), `SystemAccount<'info>`, and `UncheckedAccount<'info>` (no validation, use carefully).

Developer Tools

Anchor Constraints

Declarative validation rules on Anchor account fields. Key constraints: `#[account(mut)]` (writable), `#[account(init, payer=x, space=n)]` (create), `#[account(seeds=[...], bump)]` (PDA validation), `#[account(has_one=field)]` (field equality), `#[account(constraint = expr)]` (custom boolean), `#[account(close=target)]` (close and reclaim rent).
