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.
Place the term inside its Solana layer so the definition is easier to reason about.
Anchor, local validators, explorers, SDKs, and testing workflows.
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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.

Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
Web-based blockchain browsers that index and visualize Solana ledger data including transactions, accounts, blocks, validators, and token metadata in human-readable form. Explorer.solana.com is the official Solana Labs explorer; Solscan (solscan.io) is the most popular community explorer offering DeFi analytics and token holder data; SolanaFM (solana.fm) provides enhanced transaction decoding, program labeling, and cross-program invocation graphs — all connect to RPC nodes and indexers to serve their data.
The JSON-RPC 2.0 protocol interface through which clients communicate with Solana nodes to query chain state, submit transactions, and subscribe to events. Solana exposes a rich set of HTTP and WebSocket endpoints (e.g., getAccountInfo, sendTransaction) that abstract direct peer-to-peer network participation, making RPC the primary integration point for wallets, dApps, and indexers.
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.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
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.

A comprehensive mobile development toolkit for building Solana-native Android dApps, including an SDK for wallet integration, a Seed Vault for secure key management, and the Solana dApp Store for distribution outside traditional app stores. SMS enables mobile-first interaction with Solana programs, token management, and transaction signing from Android devices.

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).
