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 and pick the chains, for example Robinhood Chain and Base.
2. Your wallet confirms one launch per chain. Each chain gets the same name, ticker and picture, and its own bonding curve.
3. Buys on every chain are added up, in dollars, toward one shared graduation target. Everyone sees a single progress bar and the live race between chains.
4. When the total reaches the target, the chain holding the most money wins. Its curve graduates into a trading pool that is locked forever.
5. On the other chains buying stops. Holders there can sell back to the curve at any time and take their money, or move it to the winning chain.

Why a shared target graduates faster

A coin on one chain has to find all of its buyers on that chain. A coin on several chains draws from all of their communities at once, so the same target is usually reached much sooner. For creators that means less time in the fragile early phase; for buyers it means they can join from wherever their money already is.

Who decides the winner?

Chains cannot see each other, so a small program called a keeper adds up the curves across chains and triggers graduation. On sasa the keeper's power is deliberately narrow: it can only graduate or close a curve. It cannot move anyone's money, graduation can only send funds into the locked pool, and a chain holding almost nothing can never be made the winner. Every decision is published with a report of the numbers behind it, so anyone can check it against the chains.

Things to know

• Each chain's curve prices the coin separately, so the price can differ slightly between chains. sasa's trade box picks the cheapest chain where your wallet has funds.
• Holding the coin on a chain that did not win is not a loss by itself: you can always sell back there at the curve price.
• Network fees apply on each chain you launch on, but on the supported chains they are usually cents.
