$ETH

An **ETH marketplace** is a decentralized platform built on Ethereum, enabling peer-to-peer trading of digital assets like NFTs, tokens, or virtual goods. Powered by smart contracts, it ensures secure, trustless transactions without intermediaries. Popular examples include **OpenSea** (NFTs), **Uniswap** (tokens), and **Rarible** (creator economies). Users connect wallets like MetaMask to buy, sell, or auction items, paying gas fees in ETH. Benefits include transparency, global access, and censorship resistance, but challenges like high fees and scalability persist. ETH marketplaces drive Web3 adoption, merging finance, art, and tech in a decentralized ecosystem.
