Key terms and concepts used throughout this documentation.
MEV (Maximal Extractable Value)Profit available from reordering, inserting, or censoring transactions within a blockchain block. Formerly called 'Miner Extractable Value' in proof-of-work systems.
Atomic transactionA transaction that either fully executes (all operations succeed) or fully reverts (all operations are undone). No partial execution is possible. This guarantees that you cannot lose your principal in an atomic MEV trade.
MempoolThe queue of unconfirmed transactions waiting to be included in a block. MEV bots scan the mempool to identify profitable opportunities before transactions are finalized.
RugpullA type of cryptocurrency scam where token creators attract buyers, then drain all liquidity from the trading pool — making the token worthless and leaving buyers with irrecoverable losses.
DEX (Decentralized Exchange)A protocol for trading tokens peer-to-peer without intermediaries or centralized custody. Examples: Uniswap, PancakeSwap, Raydium.
GasThe fee paid to network validators for processing and confirming transactions. Gas costs vary by network — from fractions of a cent on Solana to several dollars on Ethereum mainnet.
Non-custodialA system where users retain full control of their private keys and funds at all times. The platform cannot move, freeze, or seize your assets. Nonce is non-custodial by design.
Sandwich tradeAn MEV strategy where a bot places a buy order before a detected large swap (front-running) and a sell order after it (back-running), profiting from the price impact caused by the large swap.
SlippageThe difference between the expected price of a trade and the actual price at which it executes. Higher slippage means worse execution; MEV bots can exploit transactions with high slippage tolerance.
Front-runningSubmitting a transaction ahead of a detected pending transaction to profit from the anticipated price movement. A key component of sandwich trades and certain arbitrage strategies.
