MEV (Maximal Extractable Value)

The profit validators/block producers can extract by reordering, inserting, or censoring transactions within a block. MEV includes frontrunning (trading before a large order), sandwich attacks (surrounding a swap with buy/sell), and arbitrage. On Solana, Jito's block engine provides an MEV auction system where searchers submit bundles with tips.

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.

Branch

MEV (Maximal Extractable Value)

The profit a block producer (leader) or sophisticated trader can extract by controlling the ordering, inclusion, or exclusion of transactions within a block — including strategies like front-running, back-running, sandwich attacks, and arbitrage. On Solana, MEV dynamics differ from Ethereum because there is no public mempool; transactions are forwarded directly to the current leader, making latency and validator relationships central to MEV capture. The Jito infrastructure provides the dominant MEV marketplace on Solana through bundles and tips.

Branch

Sandwich Attack

A form of MEV where an attacker places one transaction immediately before (front-run) and one immediately after (back-run) a victim's large AMM swap: the front-run buys the asset first, driving up the price the victim pays, and the back-run sells the asset immediately after the victim's transaction at the inflated price, extracting the difference as profit. On Solana, sandwich attacks are facilitated through Jito bundles, which allow searchers to atomically guarantee ordering of multiple transactions within a block. Victims can mitigate exposure by setting tight slippage tolerances (e.g., 0.1–0.5%) and using DEX aggregators that route across multiple pools to reduce single-pool price impact.

Branch

Arbitrage

The practice of profiting from price differences for the same asset across different markets. On Solana, arbitrage bots exploit price discrepancies between DEXs (e.g., SOL/USDC on Orca vs Raydium) or between spot and perpetual prices. Arbitrage is often executed via Jito bundles for guaranteed atomic execution and front-running protection.

Mooning

Describes a token's price increasing dramatically and rapidly. 'When moon?' is the canonical impatient question asked by holders waiting for significant price appreciation. The term derives from 'to the moon,' a phrase popularized by Dogecoin and broader crypto communities expressing hope for extreme upward price movement. Often used hyperbolically for any notable price increase.

Web3dex-general

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.

Web3nft-general

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.
