A lightweight local Solana validator for development. Runs a single-node cluster on localhost:8899 (RPC) and localhost:8900 (WebSocket). Supports `--clone` to copy mainnet accounts, `--bpf-program` to load programs, and `--reset` to clear state. Processes transactions instantly without PoH delays. Useful for rapid iteration but doesn't simulate network conditions.

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.
The practice of developing and testing Solana programs against a local validator (solana-test-validator) or in-process test harness (Bankrun, LiteSVM). Local development allows instant transaction confirmation, free airdrops, account cloning from mainnet, and rapid debugging. Programs are deployed locally before moving to devnet for integration testing.

The Rust crate (solana-sdk) providing types and utilities for building Solana clients and programs. For on-chain programs, use `solana-program` (no-std compatible subset). For off-chain clients, use `solana-sdk` (full features including keypair generation, transaction signing). The SDK includes types like Pubkey, Instruction, Transaction, and Account.
Solana's built-in testing framework that spins up a lightweight BanksClient runtime to execute programs in an isolated environment without a full validator. Supports adding programs, setting account state, advancing slots/time, and processing transactions. The foundation for most Solana program integration tests.

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.
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.
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).
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).
