This glossary defines 56 terms you'll meet in Solana trading bots and memecoin terminals, each in one or two sentences. Where a term involves a fee, a setting or a security risk, we link to the source or to a longer guide. Definitions reflect docs checked September 26, 2026.
Risk notice: Crypto trading is high risk and memecoins can go to zero in minutes. Trading bots use hot wallets. This page is not financial advice; only trade what you can afford to lose.
New to all of this? Start with what is a Solana trading terminal and what is Pump.fun, then come back here as you need.
A
AMM (automated market maker). A pool that prices trades with a formula instead of an order book. Pump.fun's bonding curve is a constant-product AMM (Pump.fun).
Anti-MEV. A bot setting that routes your trade privately to reduce sandwich attacks; GMGN's version needs at least 0.002 SOL in priority fees (GMGN). See MEV protection explained.
ATH (all-time high). The highest price a token has ever traded at.
Auto buy / auto sell. Rules that trade for you when a condition is met, such as buying as soon as you paste a CA or selling at a set percentage gain or loss.
B
Base fee. Solana's fixed 5,000 lamports per signature, half burned and half paid to the validator (Solana).
Bonding curve. A launchpad's pricing formula that raises the price with every buy and lowers it with every sell until the token graduates.
Bribe. Bot slang for a validator tip, usually a Jito tip, paid to get your transaction included faster (Axiom).
Bundle. On Jito, up to 5 transactions executed in order and all-or-nothing (Jito). In memecoin talk, a "bundled launch" packs token creation and buys from several insider wallets into one block, hiding how much supply insiders hold (GMGN).
Burner wallet. A separate wallet used only for trading, kept small so a compromise doesn't touch your savings. See Telegram trading bot security.
C
CA (contract address). A token's unique on-chain address; on Solana, its mint address. Trade by CA, not ticker, to avoid copycats.
Cashback. A share of the bot's fee returned to you. Trojan gives every user 20%, and Axiom's cashback lowers its net fee to 0.75%-0.95% (Axiom).
Compute units. Solana's measure of how much work a transaction does; the priority fee is priced per compute unit (Solana).
Copy trade. A bot feature that automatically mirrors another wallet's trades. See copy trading Solana wallets explained.
D
DCA (dollar-cost averaging). Splitting a buy or sell into smaller orders over time, such as BONKbot's DCA orders with a set number of transactions and interval (BONKbot).
DEX (decentralized exchange). An on-chain exchange such as PumpSwap or Raydium, where tokens trade from liquidity pools.
Dev wallet. The wallet that created a token. How much it holds, and whether it has sold or launched failed tokens before, is a key risk signal.
E
Exit liquidity. Buyers whose purchases let earlier holders sell at a profit. If you buy late into a pump, you may be someone's exit liquidity.
F
FDV (fully diluted valuation). Price times total supply, including tokens not yet circulating. Compare with market cap.
Freeze authority. The account allowed to freeze tokens in a holder's account so they can't be transferred (Solana). If active, the creator could stop you selling.
G
Graduation. When a Pump.fun token's bonding curve completes and its liquidity moves to PumpSwap (Pump.fun). Also called migration.
H
Honeypot. A token you can buy but can't sell, because the creator restricts sales (GMGN). On Solana, an active freeze authority is the main honeypot risk.
Hot wallet. A wallet whose key is online. All bot and terminal wallets are hot wallets; Trojan tells users to "always treat your wallet as a hot wallet" (Trojan).
J
Jito. The company behind the Jito-Solana validator client, which over 92% of stake ran as of January 2025, and a block engine that auctions transaction priority (Helius).
Jito tip. A SOL payment to a Jito tip account to win that auction; the minimum is 1,000 lamports (Jito).
K
KOL (key opinion leader). An influencer or caller whose posts and wallet are watched by followers. KOL wallets are popular copy trading targets, and some sell into the buying they create.
L
Lamport. The smallest unit of SOL; 1 SOL is 1,000,000,000 lamports.
Limit order. An order that executes only when a token hits your chosen price or market cap.
Liquidity. The funds in a token's pool. Thin liquidity means big price moves and high slippage.
LP burn. Destroying the LP tokens that can withdraw a pool's liquidity, so no one can pull it. Pump.fun's developer docs say LP tokens are burned when a token graduates (Pump.fun).
M
MC (market cap). Token price times circulating supply. Terminals often show launches by MC rather than price.
Mempool. A waiting area for unconfirmed transactions. Jito shut its Solana mempool service in March 2024 because it enabled sandwich attacks (CoinDesk).
MEV (maximal extractable value). Profit made by reordering or inserting transactions around yours. Sandwich attacks are the kind that hurts memecoin traders.
Migration. A token moving from a launchpad's bonding curve to a DEX pool. Axiom and Trojan offer migration buys and snipes.
Mint authority. The account allowed to create new units of a token (Solana). BONKbot's docs say it should be disabled (BONKbot).
N
Non-custodial. The platform says it can't move your funds and you can export your key. It still means a hot wallet the platform's software signs from.
P
PnL (profit and loss). Your gain or loss on a position. "Unrealized" PnL is on paper; "realized" is after you sell. Work out a trade's PnL after fees with our memecoin PnL calculator.
Priority fee. An optional fee, priced per compute unit, that raises your transaction's scheduling priority; it's charged even if the transaction fails (Solana). See priority fees and slippage.
Private key. The secret that controls a wallet. Anyone with it can take your funds, so never share it or paste it into sites.
Pump.fun. Solana's largest memecoin launchpad, where coins are free to create and trade on a bonding curve (Pump.fun).
PumpSwap. Pump.fun's DEX, launched in March 2025, where graduated tokens trade (The Block).
R
Rug (rug pull). When creators or insiders take the value out of a token, by pulling liquidity, minting, freezing or dumping supply. See how to spot a rug pull on Solana.
S
Sandwich attack. An attacker buys just before your trade and sells just after it, profiting from the price your trade moved (Helius).
Seed phrase. A list of words that can restore a wallet and every key in it. Axiom shows one at sign-up; never share it (Axiom).
Slippage. The maximum price change you accept between sending a trade and it filling. Trojan's default is 15% (Trojan).
Smart money. Wallets with strong track records that tools like GMGN highlight for tracking and copying.
Sniper. A bot, or a buyer using one, that buys a token in the first seconds of launch or migration. See best Solana sniper bot.
SPL token. A token built on Solana's token program; nearly every Solana memecoin is one.
Stop loss. A sell order that triggers when price falls to a level you set, to limit losses. Fast crashes can still fill below it.
T
Take profit. A sell order that triggers when price rises to a level you set.
Telegram bot. A trading bot you use inside a Telegram chat, such as Trojan or BONKbot.
Trading terminal. A web app with token feeds, charts and one-click trading, such as Axiom or Photon.
Trailing stop loss. A stop loss that moves up as price rises, tracking the highest price since you set it.
Trenches. Slang for the stream of brand-new launches; also the name of new-token feeds in GMGN, Trojan's web terminal and Terminal.
TWAP (time-weighted average price) order. An order split into equal slices over a period to reduce price impact. Older reviews listed it for Padre (Terminal), but Terminalpedia found no TWAP in Terminal's code (August 19, 2026).
W
Wallet tracker. A tool that alerts you when chosen wallets trade, without copying them automatically. Axiom offers tracking but no native copy trading.
WSOL (wrapped SOL). SOL in SPL token form, used inside some swaps. GMGN's bot can settle in WSOL and lets you convert it back to SOL (GMGN).
