How crossr works

Cross-chain

Launching signs one transaction on the home chain. The LaunchRelay sends the manifest to every other chain through LayerZero V2, where the peer launchpad deploys the same token address and opens that chain's curve in its own coin (ETH on Robinhood, BNB or a BEP-20 on BNB Chain, …).
If a chain is not wired to the relay yet, the creator can create that leg directly on that chain with the same manifest.
The TokenBridge burns on the source chain and mints on the destination, so global supply is constant. Bridged tokens can be sold into the destination curve (up to what that curve has sold) or its pool, which keeps prices aligned across chains through arbitrage.

The first chain is where you sign. Every chain gets its own curve in the coin you pick and its own share of the supply.
