The Solana memecoin glossary

A plain-English Solana memecoin glossary

Memecoin culture moves faster than its own dictionary, and the same word often means slightly different things on Twitter, in a Telegram call and in a block explorer. The entries below aim for the plain, honest meaning - what the term actually points at on-chain - rather than the hype version. Where a term connects to how a volume campaign is shaped, we keep the site's idea that volume is a waveform you steer, not a single number you buy.

New to launches? The volume guide walks through a full campaign, and the bonding curve explained goes deep on the one mechanic every Pump.fun token shares. Terms are grouped loosely from launch mechanics to market plumbing to tooling and risk.

Pump.fun

A Solana launchpad where anyone can deploy a token in seconds and trade it against an automated bonding curve, with no upfront liquidity required from the creator. It is the default venue for fair-launch memecoins on Solana.

Bonding curve

A pricing formula built into the contract that sets the token price automatically from how many tokens have been bought: each purchase pushes the price up along the curve, each sale pushes it down. It lets a token trade instantly at launch without a traditional order book or seeded pool.

Graduation

The moment a Pump.fun token has sold enough of its bonding-curve supply to hit its threshold and migrate to an open market, where its collected liquidity is deposited into a Raydium pool. After graduation the token trades on a standard AMM rather than the curve.

Raydium

A major Solana automated market maker and liquidity venue where tokens trade after they leave the Pump.fun bonding curve. Graduated tokens get a Raydium pool seeded with the SOL their curve accumulated. See the bonding curve explainer for how the handoff works.

Liquidity pool

A smart-contract reserve holding two assets - typically a token and SOL - that traders swap against. The ratio of the two assets in the pool sets the price, and deeper pools move less per trade.

AMM

Short for automated market maker: a protocol that prices swaps with a formula against a liquidity pool instead of matching buyers and sellers through an order book. Raydium is the AMM most Pump.fun tokens land on after graduation.

Slippage

The difference between the price you expect and the price you actually get, caused by the pool moving between when you submit a trade and when it settles. Thin liquidity and large orders both widen slippage.

Market cap

The token price multiplied by its circulating supply, used as a rough headline size for a memecoin. On the bonding curve it is often quoted as a fully diluted figure, so treat it as a signal of attention rather than of real money that could be withdrawn.

SOL

The native token of the Solana blockchain, used to pay transaction fees and as the base asset most memecoins trade against. Bonding-curve buys and Raydium swaps are almost always priced in SOL.

Contract address (CA)

The unique on-chain address that identifies a specific token, sometimes called its mint. Traders paste the CA to verify they are buying the right token, and it is the only identifier that cannot be faked by copycats.

Volume bot

Software that directs many wallets to buy and sell a token on a schedule, producing real on-chain trading volume so a launch reads as active to the feed and to passing traders. A volume bot buys visibility by making genuine activity legible; it does not create demand - see bundler vs volume bot.

Volume waveform

The live curve of a campaign's buys and sells over time, viewed as a shape rather than a total. A believable waveform has amplitude and rhythm without an obvious repeating interval; a flat trickle or a single vertical wall reads as fake.

Rotating wallet fleet

A pool of many separate funded wallets that a campaign cycles through so trades come from a wide set of addresses instead of one busy account. Rotation across fresh wallets is what stops on-chain activity from looking like a single actor talking to itself.

MEV

Maximal extractable value: profit that block producers or bots capture by reordering, inserting or censoring transactions within a block. On Solana it shows up as bots front-running or sandwiching trades to skim value from ordinary swaps.

Sandwich attack

A form of MEV where a bot places a buy just before your trade and a sell just after it, pushing the price against you so it pockets the difference. Larger swaps into thin pools are the usual targets.

Jito

A Solana infrastructure project best known for its block-engine and bundle system, which lets searchers submit ordered groups of transactions with tips to validators. It is central to how MEV and transaction bundling work on Solana.

Bundler

A tool that packages several transactions to execute together in a set order, often used at launch to buy a large share of supply in the same block a token is created. A bundler concentrates buying into one moment, which is the opposite of the spread-out shape a volume waveform aims for.

Snipe

To buy a token in the first block or first seconds after it launches, usually with automated tooling, in the hope of getting in before the price climbs the curve. Snipers can dominate early supply, which is why fair-launch distribution is prized.

Holder

A wallet that currently owns a nonzero balance of a token. Holder count is a rough gauge of how widely distributed a token is, and steady holder growth is one of the signals a healthy launch tends to show.

Trending feed

The ranked list of tokens a launchpad surfaces to traders based on recent activity such as volume, trade frequency, holder growth and social engagement. Getting onto the trending feed during the launch window is what most campaigns are chasing.

Rug pull

When a token's creator abandons or drains a project - pulling liquidity, dumping their supply or disabling trading - leaving other holders with worthless tokens. It is the defining risk of unvetted memecoins and the reason people verify contracts before buying.

Non-custodial

A design where you keep control of your own funds and keys and the tool never holds them for you. A non-custodial campaign takes only a public contract address and the SOL you choose to fund, and never asks for a seed phrase or private key.

Anti-MEV routing

Sending transactions through paths or private channels designed to reduce their exposure to front-running and sandwich bots. It aims to get trades included without broadcasting them where predatory bots can react first.

Auto-comments

An engagement feature that posts comments on a token's launchpad page at a set frequency, so the discussion area is not silent while volume runs. It is meant to keep the social signal consistent with the trading activity, not to fabricate a community.

Auto-favorites

An engagement feature that adds a token to watchlists or marks it as a favorite at a chosen pace, feeding the watch signal some feeds weigh. Like auto-comments, it exists to keep the whole picture coherent rather than to guarantee an outcome.

Memecoin

A token whose value comes mostly from attention, community and culture rather than a product or cash flow. Solana memecoins are typically fair-launched, cheap to deploy and highly volatile.

Deployer

The wallet that created a token by paying to mint it on the launchpad. Traders inspect the deployer's history and holdings to judge intent, since a deployer holding a large share of supply can dump it.

Fair launch

A launch where everyone buys from the same bonding curve at the same starting terms, with no pre-sale, team allocation or insider pricing. Pump.fun's model is fair-launch by default, though snipers and bundlers can still skew who gets in first.

Bonding curve graduation threshold

The specific amount of curve supply that must be sold, or market cap that must be reached, before a token graduates from Pump.fun to a Raydium pool. Hitting the threshold triggers the liquidity migration and the switch from curve pricing to AMM pricing.

Non-fungible attention

The idea that a memecoin's scarce resource is not its supply but the market's attention at a given moment, which cannot be duplicated or reclaimed once it moves on. It is why timing and visibility during the launch window matter more than raw token counts.
