Solana memecoin & Pump.fun glossary
The terms below are the working vocabulary of a Pump.fun launch - what a bonding curve is, why volume velocity matters more than raw volume, what Jito and MEV mean, and what happens at graduation. Each definition is written to stand on its own, so you can skim to the one you need. For how these pieces fit together in practice, see the volume-bot guide and the trending playbook.
Pump.fun
A Solana launchpad where anyone can deploy a token in seconds. New tokens trade against a bonding curve until they hit a cap and migrate to a Raydium pool. Pump.fun also surfaces tokens through a trending feed driven by volume and social activity.
Bonding curve
A pricing formula that sets a token's price directly from how much of the supply has been bought. Each buy moves the price up the curve and each sell moves it down, with no order book. On Pump.fun the curve is the entire market for a token until it graduates.
Volume bot
Software that places real buy and sell orders on a token across many separate wallets, on timed and varied intervals, to build the volume and activity signals that a launchpad or DEX ranks on. A Pump.fun volume bot pairs trades with comments and favorites so the footprint reads as a community.
Solana volume bot
A volume bot built for the Solana chain, using Solana wallets, RPC submission and Jito relays. It generates on-chain trading volume on Solana tokens, most often Pump.fun launches and their post-migration Raydium pairs.
Trending feed
Pump.fun's ranking of tokens by momentum rather than market cap. It weighs how fast a token's signals are climbing right now - volume velocity, unique-holder growth, comment cadence and favorites - and favors activity that looks like independent people arriving.
Volume velocity
The rate at which trading volume is accumulating, not the raw total. The trending feed rewards a steep, recent slope, so a token building volume quickly can outrank an older one sitting on a larger but flat number.
Unique holders
The count of distinct wallets holding a token. Because it is the hardest signal to fake, both algorithms and human buyers treat a high holder count as strong evidence of genuine interest - two hundred holders beats two whales.
Auto-comments
Comments posted on a token's Pump.fun page from many distinct wallets, ideally in varied voices and languages, loosely correlated with trades. A moving chart with no comments looks wrong; comment cadence is one of the signals the feed reads.
Favorites
Stars placed on a token by distinct wallets, feeding the watchlist-velocity signal that can surface a token before its volume is obvious. Spread across many wallets, favorites read as organic attention.
Wallet fleet
The set of separate wallets a volume bot trades from. A serious tool rotates a fresh fleet each session, funds each wallet with randomized amounts and never reuses addresses across runs, so the activity does not cluster to one source.
Wallet persona
A behavior profile assigned to a wallet - such as whale, retail, dev or skeptic - with its own trade size, timing and comment voice. Personas make a fleet's activity read as a mix of different participants rather than one script.
Jito
A Solana infrastructure provider whose bundles let transactions be submitted through a private relay with a tip, instead of the public mempool. Routing trades through Jito hides them from public-mempool observers and shields them from sandwich bots.
MEV
Maximal Extractable Value - profit that bots capture by reordering, inserting or front-running transactions. On a DEX, the common attack is a sandwich, where a bot buys just before and sells just after a victim's trade to skim the price impact.
Anti-MEV routing
Submitting trades through a private relay such as Jito, with randomized tips and irregular timing, so they cannot be seen and sandwiched in the public mempool. It protects both the price you get and the privacy of your pattern.
Graduation
The moment a Pump.fun token completes its bonding curve by hitting the cap. At graduation, accumulated liquidity is deposited into a Raydium pool, the bonding-curve page stops taking orders, and the token trades as an ordinary DEX pair.
Migration
The handoff of a graduated token from the Pump.fun bonding curve to a Raydium AMM pool. It is often the highest-visibility moment of a launch, since external aggregators list the new pair and a wider audience arrives.
Raydium
A leading Solana automated market maker. After a Pump.fun token graduates, its liquidity moves into a Raydium pool where it trades against a constant-product curve, and where aggregators like Dexscreener pick it up.
AMM
Automated Market Maker - a DEX model where trades execute against a liquidity pool by formula rather than an order book. Price moves with pool depth and trade size, and slippage scales with how much liquidity sits in the pool.
Cross-DEX mirror
Optionally mirroring a token's volume across additional Solana DEXes such as Meteora and Orca, so the token shows activity on more than one venue and gains visibility on multi-DEX aggregators.
Non-custodial
An operating model where a tool never holds your primary private key. You fund a deposit wallet, the tool derives disposable sub-wallets from it, and unused deposit is refunded when a session stops. The main wallet stays under your control throughout.
Volume curve
A preset that shapes how a session's volume is delivered over time - for example gradual, burst, stealth or whale. The curve controls the rhythm of buying and selling so the tape matches the launch strategy.
Buy/sell ratio
The proportion of buys to sells in a session. A slight buy bias trends the chart upward without looking mechanical; an even or sell-heavy ratio holds or eases price. It is one of the core tunable parameters of a volume bot.
That is the core vocabulary. When you are ready to put it to work on a launch, open the dashboard, or read the volume-bot guide for how these terms fit together in practice.
