When creating your account, you will have the choice of minting your NFTs on Polygon or Ethereum. We encourage our merchant to decide between the blockchains depending on factors such as gas fees and the NFT value when being sold.
Ethereum 
The advantage of using Ethereum is that this is the "premium" NFT blockchain network and provides access to the most liquidity. The disadvantage is that the NFT buyer will have to pay for gas fees for processing their transaction. Note that sellers on RareCircles do not pay for gas fees.
Polygon 
The advantage of using Polygon is that their network will have much lower gas fees than the Ethereum network. Gas fees are almost non-existent on Polygon and are paid by RareCircles. We recommend choosing Polygon if you are selling items for less than $300 each.
