Solana memecoin & launchpad glossary
The terms below are the working vocabulary of a Solana launch across Pump.fun and Bonk.fun - 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 stands 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
The best-known Solana launchpad, where anyone can deploy a token in seconds. Fresh tokens trade against a bonding curve until they reach a cap and migrate to a Raydium pool. Pump.fun also ranks tokens on a trending feed fed by buy activity and social signals.
Bonk.fun
A Solana launchpad tied to the BONK ecosystem, also known as LetsBonk and reachable at letsbonk.fun. Like Pump.fun, it deploys tokens against a bonding curve that graduates to Raydium, and it runs its own trending board with a distinct audience.
LetsBonk
The common name for the Bonk.fun launchpad and its interface at letsbonk.fun. The two names refer to the same venue; a token launched on LetsBonk follows the same curve-to-Raydium path as one launched on Pump.fun.
Bonding curve
A pricing formula that reads a token's price straight from how much of the supply has been bought. Each buy pushes the price up the curve and each sell pushes it down, with no order book involved. On Pump.fun and Bonk.fun the curve is the whole market for a token until it graduates.
Volume bot
Software that places genuine buy and sell orders on a token across many separate wallets, on timed and varied intervals, to build the activity signals a launchpad or DEX ranks on. A capable bot pairs those trades with comments and favorites so the footprint reads like a real community.
Solana volume bot
A volume bot purpose-built for Solana, relying on Solana wallets, RPC submission and Jito relays. It generates on-chain trading activity on Solana tokens - Pump.fun and Bonk.fun launches and their post-migration Raydium pairs alike.
Trending feed
A launchpad ranking that sorts tokens by momentum rather than market cap. Pump.fun and Bonk.fun each run one, weighing how fast a token's signals are climbing right now - buy velocity, holder growth, comment cadence and favorites - and favoring activity that looks like independent people arriving.
Volume velocity
The rate at which trading activity is accumulating, not the raw total. Trending boards reward a steep, recent slope, so a token building volume quickly can outrank an older one sitting on a larger but flat figure.
Unique holders
The number of distinct wallets holding a token. Because it is the hardest signal to fake, both ranking logic and human buyers read a high holder count as strong evidence of real interest - two hundred holders beats two whales.
Auto-comments
Comments posted on a token's launchpad page from many distinct wallets, ideally in varied voices and languages and loosely tied to the trades. A climbing chart with no comments looks wrong; comment cadence is one of the signals a board reads.
Favorites
Stars a token collects from separate wallets, powering the watchlist-velocity signal that can lift a token into view before its volume is obvious. Spread across many wallets, favorites read as genuine attention.
Wallet fleet
The pool of distinct wallets a volume bot places trades from. A serious tool rotates a fresh fleet each session, funds each wallet with randomized amounts, and never reuses addresses between runs, so the activity does not trace back to a single source.
Wallet persona
A behavior profile assigned to a wallet - whale, retail, dev or skeptic, for example - each with its own trade size, timing and comment voice. Personas make a fleet read as a mix of different participants rather than one script.
Jito
A Solana infrastructure provider whose bundles route transactions through a private relay in exchange for a tip, bypassing the public mempool. Routing trades through Jito keeps them out of view of mempool observers and shields them from sandwich bots.
MEV
Maximal Extractable Value - the profit bots capture by reordering, inserting or front-running transactions. On a DEX the usual 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
Sending trades through a private relay such as Jito, with randomized tips and irregular timing, so they cannot be spotted and sandwiched in the public mempool. That guards both the fill you receive and the confidentiality of your trading pattern.
Graduation
The moment a launchpad token completes its bonding curve by hitting the cap. At graduation the 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 launchpad 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 shows up.
Raydium
One of Solana's major automated market makers. After a Pump.fun or Bonk.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 design where swaps settle against a shared liquidity pool through a formula instead of a matched order book. The price shifts according to pool depth and order size, and slippage grows as the pool holds less liquidity.
Cross-DEX mirror
Optionally mirroring a token's volume onto additional Solana DEXes such as Meteora and Orca, so the token shows activity on more than one venue and gains reach on multi-DEX aggregators.
Non-custodial
An operating model in which a tool never holds your primary private key. You top up a deposit wallet, the tool spins throwaway sub-wallets out of it, and any leftover deposit is returned once a session ends. The main wallet stays under your control the whole time.
Volume curve
A preset that shapes how a session's volume is delivered over time - gradual, burst, stealth or whale, for example. The curve governs the cadence of buys and sells so the tape lines up with the launch strategy.
Buy/sell ratio
The balance of buys against sells within a session. A slight buy bias nudges the chart upward without looking mechanical; an even or sell-heavy ratio holds or eases the price. It ranks among 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.
