When you create your first contract, you will come across this first screen in the wizard.
Choose your preferred blockchain to publish your NFTs to. HyperMint currently supports Ethereum, Polygon, and Solana (Beta).
Ethereum is preferred choice for smaller collections that indicate and imply some exclusivity as well as high value. Polygon is preferred choice for large collections that need to be minted at scale as gas fees are much lower on Polygon.
*Please note that HyperMint will cover any gas fees if your NFTs are on the Polygon network.
