At the beginning of last year, OpenSea bought the NFT marketplace aggregator Gem. Together with the OpenSea - Gem team, it has been redesigned into OpenSea Pro, and now it is the fastest and most powerful of the available NFT aggregators on the market now.
OpenSea.io returns to the standard trading platform commission of 2.5%, but through OpenSea Pro you can still place your NFT on OpenSea with zero fee during the promotion period.
