DEX (General Concept)

A decentralized exchange allowing peer-to-peer token trading without a centralized order book or custodian. Users trade directly from their wallets. DEXs use automated market makers (AMMs) or on-chain order books. Advantages: no KYC, self-custody, censorship-resistant. Disadvantages: potential for higher slippage, smart contract risk, and MEV extraction.

Mental model

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.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

Wallets, signing flows, dApps, and key management concepts.

Why builders care

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.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

DEX (Decentralized Exchange)

A protocol for trading tokens directly on-chain without a centralized intermediary. Solana DEXs use either AMM pools (Raydium, Orca, Meteora) or on-chain order books (Phoenix, OpenBook). DEXs are composable—aggregators like Jupiter route through multiple DEXs for optimal pricing.

Branch

AMM (Automated Market Maker)

A protocol that enables token swaps using algorithmic pricing against pooled liquidity instead of matching individual buyers and sellers. AMMs use mathematical formulas (typically constant product x*y=k) to determine prices based on the ratio of tokens in a liquidity pool. On Solana, major AMMs include Raydium, Orca, and Meteora.

Branch

CEX (Centralized Exchange)

A traditional cryptocurrency exchange operated by a company that custodies user funds and matches orders on internal systems. Examples: Coinbase, Binance, Kraken. CEXs offer fiat on/off ramps, high liquidity, and familiar UX but require KYC and trust in the operator. Users deposit crypto and trade against the exchange's internal ledger, not directly on-chain.

Diamond Hands

Holding a position through extreme price volatility without selling, implying conviction and psychological resilience. The diamond emoji became shorthand during the 2021 bull cycle across crypto and meme stock communities. Diamond hands is celebrated when the asset eventually recovers or appreciates, but can also lead to significant losses if conviction is misplaced. Counterpart to paper hands.

NFT (General Concept)

A unique, non-interchangeable digital token representing ownership of a specific asset—artwork, collectibles, music, game items, domain names, or real-world assets. NFTs are verified on-chain and can be traded on marketplaces. Unlike fungible tokens (where each unit is identical), each NFT has distinct properties. Major Solana NFT marketplaces: Magic Eden, Tensor.

Web3

Web3

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.

Web3

dApp (Decentralized Application)

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).

Web3

Wallet

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.

Web3

Seed Phrase (Mnemonic)

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.
