Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts.

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 building block that connects one definition to the larger Solana system around it.
Place the term inside its Solana layer so the definition is easier to reason about.
Wallets, signing flows, dApps, and key management concepts.
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.
Wallet (wallet-general) Category: Web3 Definition: Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts. Aliases: Crypto Wallet Related: Keypair, Wallet Adapter
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.
A TypeScript/JavaScript library maintained by Solana Labs (now under the Anza umbrella) that provides a unified interface and React context for connecting to and interacting with browser extension wallets (Phantom, Backpack, Solflare, etc.) using the Wallet Standard. It abstracts wallet-specific APIs behind a common connect/disconnect/signTransaction/sendTransaction interface, allowing dApps to support all compliant wallets without custom per-wallet integration code.
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.
Acronym for 'We're All Gonna Make It.' An expression of collective optimism and community solidarity used during bull markets, protocol milestones, and positive announcements. WAGMI reinforces group cohesion and shared belief in long-term success. The counterpart to NGMI, it originated from bodybuilding culture and was adopted by crypto communities during the 2021 bull cycle.
The vision of a decentralized internet built on blockchain technology, where users own their data, identity, and digital assets. Web1 was read-only (static pages), Web2 is read-write (platforms like social media), Web3 is read-write-own (permissionless, user-sovereign). Web3 applications use wallets instead of logins and smart contracts instead of centralized servers.
An individual or entity holding a very large amount of a particular cryptocurrency or token, enough to potentially influence market prices through their trading activity. On Solana, whale movements can be tracked on-chain by monitoring large token transfers or wallet balances via explorers and analytics tools. Whale activity is closely watched because large buys or sells can cause significant price swings, especially in tokens with lower liquidity.

An application with its backend logic running on a blockchain as smart contracts rather than centralized servers. dApps typically have a traditional web frontend that interacts with on-chain programs via RPC. Users authenticate with wallets instead of username/password. Examples: Uniswap (Ethereum DEX), Jupiter (Solana DEX), Magic Eden (NFT marketplace).
A 12 or 24-word human-readable backup of a wallet's master private key, generated using BIP-39 standard. The seed phrase can deterministically regenerate all derived keypairs (BIP-44 derivation paths). Losing the seed phrase means permanently losing access to all associated accounts. Never share, photograph, or store seed phrases digitally in plain text.
Financial services built on blockchain smart contracts that operate without traditional intermediaries (banks, brokers). DeFi includes lending, borrowing, trading, insurance, and derivatives. Key properties: permissionless (anyone can participate), composable (protocols can be combined), transparent (open-source, auditable). Solana DeFi TVL has exceeded $5B, led by Jupiter, Raydium, Marinade, and Kamino.
