What is a memecoin? Meaning, how they work and the risks

By the arky team · Last updated: 5 Oct 2026

This guide comes from arky, the trading terminal on Circle's Arc chain, where people trade and launch memecoins every day. It explains what a memecoin is, where the idea came from, how memecoin prices are set, and the risks, without the hype.

What does memecoin mean?

A memecoin (also written meme coin) is a cryptocurrency that started from an internet meme or has some other humorous character (Wikipedia: Meme coin). In February 2025 staff at the US Securities and Exchange Commission described memecoins as crypto assets "inspired by internet memes, characters, current events, or trends", bought mainly "for entertainment, social interaction, and cultural purposes", and "akin to collectibles" with limited or no use (SEC staff statement on meme coins, 27 Feb 2025).

In practice a memecoin is a standard token, often an ERC-20 or a Solana SPL token, with a name, a ticker, a picture and a story. Nothing in the code makes it a memecoin. What makes it one is that its value rests on attention and community, not on cash flows or a product.

Memecoin vs altcoin vs stablecoin: what is the difference?

A memecoin is one kind of altcoin (any coin that is not Bitcoin), defined by having no purpose beyond its community; a stablecoin is the opposite, built to hold a steady dollar price.

On Arc the two meet: memecoins are priced and traded in USDC, which is also the chain's gas token.

A short history of memecoins

Memecoins went from a single joke coin in 2013 to millions of tokens a year, and each wave made launching cheaper and faster.

The Arc wave changed the unit rather than the idea: coins priced in dollars, with gas paid in USDC. See memecoins on Arc for that market today.

How are memecoin prices set?

A memecoin's price is set by trades against a pool of money, so it moves with every buy and sell rather than by any valuation. There are two common setups:

• Bonding curve. A contract sells and buys back the token along a formula. Each buy adds money to the reserve and raises the price. When the reserve reaches a threshold, the coin "graduates" to a DEX pool. See what is a bonding curve.
• Liquidity pool. Tokens and money sit in an automated market maker such as Uniswap, and the ratio between them sets the price.

Two numbers mislead beginners. Market cap is price times total supply, so a coin with a billion tokens and a thin pool can show a large market cap that nobody could sell into. Price per token means little on its own: a coin at $0.0001 is not cheap if a billion of them exist. Liquidity depth tells you more than either.

Why do people buy memecoins?

People buy memecoins for the chance of a large gain, for the community, and because it is fun. The appeal is asymmetric: a small stake could multiply many times if a coin catches on. That asymmetry is also the trap, because the coins that multiply are a tiny minority. On pump.fun the vast majority of tokens never gain enough traction to graduate (Wikipedia).

What are the risks of memecoins?

The main risk is simple: most memecoins go to near zero. The rest of the list:

1. Rug pulls. Insiders remove liquidity or dump a hidden supply.
2. Honeypots. Contracts that let you buy but block or heavily tax selling.
3. Concentrated supply. A few wallets, including snipers that bought in the first block, hold most of the coins.
4. Fake activity. Wash trading and bundled wallets make a chart look busy.
5. Volatility. Moves of 50% in an hour are normal, both ways.
6. Base-token risk. A coin priced in SOL or ETH also moves with that token. Coins priced in USDC on Arc do not have this layer.
7. Impersonation. Copycat tickers and fake celebrity coins. Always check the contract address.
8. Tax and law. Gains are often taxable, and rules differ by country.

A practical pre-buy checklist is in how to avoid rug pulls on Arc.

Where do memecoins trade in 2026?

Most memecoin trading in 2026 happens on launchpads and DEXs on Solana, Base and BNB Chain, and since September 2026 on Arc. arky is the trading terminal on Arc: it shows new coins live, lets you buy memecoins on Arc with USDC, and lets you make a memecoin of your own. The same balance also trades Bitcoin up or down rounds and crypto perps on Arc. Terms like graduation and slippage are defined in the arky glossary.
