# Anchor

> Wiki for Anchor: the Rust framework for Solana programs (smart contracts) — program structure & macros, account constraints/types, PDAs, CPI, IDL, errors/events, SPL tokens (anchor-spl), the TS/Rust clients, testing, the CLI/AVM toolchain, and program security.
> Covers: Anchor — the Rust framework for Solana programs (smart contracts): program structure and macros (#[program], #[derive(Accounts)]), account constraints and types, PDAs, CPI, the IDL, errors/events, SPL tokens via anchor-spl (incl. Token-2022), the TypeScript and Rust clients, testing (litesvm/mollusk/fuzzing), the anchor CLI and avm toolchain, verifiable builds, and program security.
> Not covered: Broader Solana concepts — the account model, runtime, RPC, SPL internals, staking — are in the solana wiki. Also out of scope: the exhaustive account-constraint/type reference (catalogued), native (non-Anchor) program development, and Anchor changes after v1.1.1 / the source fetch date below — see the Anchor docs.
