Calyx
Calyx is a cross-chain token launchpad that lets participants join sales using any supported asset in a single transaction, with no bridging or swapping.

What is Calyx?
Calyx is a launchpad for founders running fixed-price or pro-rata token sales across multiple chains. Founders configure built-in KYB compliance and multi-chain distribution; participants join sales with assets they already hold from any supported chain and claim or trade tokens once the sale ends. Cross-chain routing and settlement run on NEAR Intents in the background.
