One launch.
Every chain.
Coins begin on a Solana bonding curve that graduates at about 25 SOL, paired with SOL. From launch they trade on Base, BNB, Arbitrum and beyond too, as one token with one supply and one price. At graduation every chain gets its own pool.
One supply, held everywhere
Every token on another chain is backed by one locked on Solana. Pick a coin to see where its supply lives right now.

How a coin crosses
Begin on Solana
Your coin opens on a bonding curve paired with SOL. Everyone buys with SOL.
Name the chains
The same token is registered on each chain you choose, tied to the Solana supply.
Graduate
At about 25 SOL, liquidity settles into PumpSwap and a pool on every chain you picked. LP tokens are burned.
Trade from anywhere
Buy or sell from any chain in one step. Tokens lock on Solana and mint on the other side, so supply never grows.
Asked often
How fast do coins graduate?
At about 25 SOL, more than three times sooner than pump.fun's 85. The curve is still smoother: a 1 SOL buy moves the price about 5%, not 7%. At graduation all the SOL goes into PumpSwap, and every other chain the coin lives on gets a Uniswap pool that starts with just the coin and fills with ETH or BNB as people buy there. Every pool opens at the same price, a little above the curve's last one, and the liquidity can never be pulled.
Can I buy or sell from another chain?
Yes, from the moment a coin launches. Buy anywhere takes SOL and delivers the coin on Base, BNB or any chain it lives on. Sell anywhere takes the coin from that chain and pays you SOL on Solana. Every trade is priced on Solana, so each chain pays the same price, and every buy pushes the coin toward graduation. Bridge moves the tokens through Wormhole and pays the gas on the other side for 0.5% (at least 0.002 SOL, or 0.03 SOL on Ethereum). Trades start at 0.1 SOL. If the price moves more than 2% before your trade lands, it cancels and nothing is spent. Selling from another chain takes two signatures: one there to send the tokens (a little of that chain's gas) and one on Solana to sell.
Do I need ETH or BNB?
Not to launch or buy. You pay in SOL and Bridge covers the gas on every other chain. You only need a little ETH or BNB if you hold the coin on that chain and sell from there.
Is it a different token on each chain?
No. It is one token with one total supply. A copy is minted on another chain only when the same amount is locked on Solana.
Why do the other chains get pools only at graduation?
Trading from every chain is open from launch, but the price lives in one place: the Solana curve. Separate pools on five chains before graduation would split each coin's money into small pools whose prices drift apart, and the curve would fill slower. At graduation each chain gets its own pool, and every pool opens at the same price.
Which chains are supported?
Base, BNB Chain, Arbitrum, Ethereum and Optimism at launch, with more added over time.
Where do creator fees go?
To the creator, in SOL, on Solana, no matter where the trading happens.
