A CLI tool for generating and managing Solana keypairs. `solana-keygen new` creates a keypair file at `~/.config/solana/id.json`. `solana-keygen grind` generates vanity addresses. `solana-keygen pubkey` displays the public key. `solana-keygen verify` confirms a pubkey matches a keypair. Keypairs are stored as 64-byte JSON arrays.

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.

solana-keygen (solana-keygen) Category: Developer Tools Definition: A CLI tool for generating and managing Solana keypairs. `solana-keygen new` creates a keypair file at `~/.config/solana/id.json`. `solana-keygen grind` generates vanity addresses. `solana-keygen pubkey` displays the public key. `solana-keygen verify` confirms a pubkey matches a keypair.

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.
A pair of a 32-byte Ed25519 private key and its corresponding 32-byte public key. Keypairs are used to sign transactions and derive account addresses. They are stored as 64-byte arrays (private + public concatenated) in JSON files by the Solana CLI. The private key should never be shared or exposed.
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.

The next-generation Solana TypeScript SDK (@solana/kit, formerly @solana/web3.js v2) featuring a modular, functional API. Unlike v1's monolithic classes, v2 uses composable functions and tree-shaking for smaller bundles. Key changes: pipe-based transaction building, codec-based serialization, and native support for versioned transactions. Significantly smaller bundle size than v1.

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).
