How Anypair works
Most launchpads pair every coin with ETH. On Anypair the creator picks the pair: ETH, a stablecoin, BTC, a real-world asset like a tokenized stock, or any token with a real pool on Uniswap, Aerodrome or PancakeSwap. Holders earn from every trade, paid in any assets the creator picks.

Launching
- Name it. A name, a ticker and a logo. Name and ticker are written into the coin and can't change.
- Pick the pair. Search any token on Base. The site checks its pools on Uniswap, Aerodrome and PancakeSwap and tells you right away if it can be used.
- Choose holder rewards. Turn them on or off. If they're on, pick up to four assets holders can be paid in: ETH, stablecoins, BTC, real-world assets or any token with a real pool.
- Launch. Optionally buy some in the same transaction, with ETH, then sign.
All 1,000,000,000 coins go into a Uniswap V4 pool at a $3,000 market cap, whatever the pair. Nobody gets an allocation, and the pool is open from the first block.
Pairs
A pair can be any ERC-20 on Base, crypto or real-world asset, that trades against ETH or USDC in a pool deep enough to price it: at least $2,500 on its ETH or USDC side. The start cap and every USD figure use a price from the pool the token really trades in.
| Where the token trades | How it's priced |
|---|---|
  ETH, USDC | Chainlink |
 Uniswap V3 | 30-minute average price |
| Uniswap V4 | A slow price that follows the pool by about 1% a minute |
 Aerodrome Slipstream | 30-minute average price |
| Aerodrome classic | Average reserves over the last 30 minutes or more |
 PancakeSwap V3 | 30-minute average price |
Averages mean one big trade can't fake a price. For a token that only trades on Uniswap V4, new launches against it wait after a sharp jump or crash, until the slow price catches up.
Uniswap V4 pools with hooks count too, so tokens from launchers like Bankr, Clanker and Zora can be pairs and reward assets as soon as their pool is deep enough.
Fee-on-transfer and rebasing tokens don't work as pairs.
B20 tokens
B20 is Base's native token standard, used for stablecoins and real-world assets. B20 tokens work as pairs and as reward assets like any other token. Their issuers can pause transfers or limit who may hold them, so a launch checks that transfers are open to Anypair's contracts and is refused if they aren't.
An issuer can change those rules after launch. If they pause transfers or block Anypair's contracts, trading through Anypair stops until they lift it. Holders keep their rewards and can claim them in whatever form the issuer still allows.
Fees
Every buy and sell pays 2%, taken in the pair token. The split is fixed when the coin launches.
Creators claim their share from the coin page or their portfolio, paid in the pair token.
Holder rewards
Each trade's holder share is spread over every wallet holding the coin, in proportion to its balance, the moment the fee arrives. Pools and the launchpad's own contracts don't count as holders.
Rewards build up in the pair token. When you claim, you choose how to take them:
Selling or sending your coins doesn't lose rewards already earned. They stay claimable.
Trading
On the site you always pay and receive ETH. If the pair is something else, the router swaps ETH into the pair on the way in and back to ETH on the way out, through the same pools that price it.
Trades from anywhere else (Uniswap, aggregators, bots) go through the same pool and pay the same 2%, so holders and creators earn from those too.
The first seconds
- Launch blockOnly the creator can buy.
- First 6 secondsNo wallet can buy or hold more than 3% of the supply.
- First 20 secondsThe fee starts at 99% and falls to 2%.
Sniping the start doesn't pay.
Rules in the contracts
- The 2% fee and its split are set at launch. No function changes them.
- Coins have no owner and no mint function. The supply is fixed at one billion.
- Holder rewards are only ever paid to the holder they belong to.
- A creator's reward assets are fixed at launch and can't be swapped later.
FAQ
Why pair with something other than ETH?
A coin paired with USDC has a stable unit of account. One paired with a tokenized stock ties it to a real-world asset. One paired with cbBTC or AERO puts its trading volume into that community's token. Holders who believe in an asset can be paid in it.
What does a launch cost?
Only gas. Base gas is a fraction of a cent to a few cents. A first buy is optional.
Why was my pair refused?
Usually because its pools are too thin to price it safely, it only trades against something other than ETH or USDC, or it has no price history yet. A B20 token is also refused if its issuer has paused it or doesn't let Anypair's contracts move it. The launch form tells you which.
Can holders be paid in something other than the pair?
Yes. The creator can pick up to four reward assets, any token with a real pool on Base. Holders can still always claim in the pair token or ETH instead.
Can I pair with a B20 token?
Yes. Stablecoins and tokenized stocks issued as B20 work as pairs and reward assets, as long as they trade in a pool deep enough to price them and their issuer lets Anypair's contracts move them.
What happens to the platform share?
It pays for running the site and the infrastructure behind it.
