In a Friday blog post, OpenSea said that the upcoming marketplace protocol called Seaport, will give users the option to buy NFTs by offering assets other than Ether (ETH).
On platforms built using Seaport, users can agree to offer ETH / ERC20 / ERC721 / ERC1155 items in exchange for an NFT, implying bartering a combination of assets.
This means that bidders can acquire NFTs using a combination of different assets instead of a single cryptocurrency like ETH. For instance, users can offer a combination of NFTs and cryptocurrencies that totals the value of the NFT that they are looking to acquire.
Seaport also allows people to filter NFTs collections by traits, enabling them to purchase NFTs featuring their preferred trait.
Offerers can also combine partial fills of offered items with criteria-based items to create standing offers to buy or sell multiple NFTs that all share a given characteristic.
The protocol will also support tipping, as long as the amount does not exceed that of the original offer.
