How to launch a token on multiple chains at once

Traditional launchpads make you pick one chain. Your coin can then only be bought by people who already have funds there, and everyone else has to bridge first, which most of them never do. A multi-chain launch removes that choice: the same coin goes live on several chains at once, and every buyer can use the chain they are already on.

How it works on sasa

1. You create the coin once on Create a coin with a name, ticker and picture, and choose a first buy on each chain in USDC.
2. The coin goes live on Base, BNB Chain, Robinhood Chain and Arc at the same moment, with the same contract address everywhere. Each chain gets a real DEX pool: coin/ETH on Uniswap v4 on Base and Robinhood Chain, coin/BNB on PancakeSwap Infinity on BNB Chain, and coin/USDC on Arc. Each chain's pool starts at a market cap of about $3,000.
3. For five minutes anyone can buy and sell on any of the four chains. Because the pools are ordinary DEX pools, DexScreener, GMGN and trading bots see the coin from the first second.
4. When the five minutes are up, the chain whose pool holds the most money, valued in dollars with Chainlink prices, wins.
5. The other pools close. Their money is converted at the Chainlink price and moved into the winner's pool minus a 2% hand-over fee, and holders' coins on those chains are moved to the winning chain automatically. The winning pool is locked forever.

Why a race instead of one chain

A coin on one chain has to find all of its buyers on that chain. A coin on four chains draws from all of their communities at once, and the market decides where it lives on instead of the creator guessing. Every race ends with a winner, so there is no long, fragile phase of waiting for a target that most coins never reach. Best chains to launch a meme coin compares the four crowds.

Who decides the winner?

Nobody picks it by hand. The rule is fixed in the contract: after five minutes, the pool holding the most money in dollars, using Chainlink prices, wins, and ties are settled by a fixed rule in the contract too. Each pool's balance is public on its chain, so anyone can check the result. Once the money has moved, the winning pool is locked: nobody, not the creator and not sasa, can pull it. How to check if liquidity is locked shows how to verify it yourself.

Things to know

• During the race each chain has its own pool, so the price can differ slightly between chains for a few minutes.
• With a sasa account, you add and withdraw USDC on the Base network only. Buys on BNB Chain, Robinhood Chain or Arc are funded from that same USDC balance in the background. See moving USDC between chains without a bridge.
• As a creator you pay a first buy and a network fee on each chain; network fees are usually a few cents. How big should your first buy be? helps you size it.
• After the race, the coin trades only on the winning chain.
