FirstMate operates a decentralized NFT marketplace aggregator that lets creators and collectors buy and sell NFTs without trading fees. It pulls listings from major marketplaces like OpenSea, LooksRare, x2y2, and Foundation to show a single view of available assets. The platform uses decentralized protocols such as Arweave, Seaport, and Reservoir to execute secure, transparent trades and offers creator tools like collector analytics, minting derivatives, and a Discord bot. Its goal is to empower artists and collectors with a fee-free, decentralized marketplace and practical tools, differentiating itself from competitors by removing fees and focusing on creators.
