Marketplace

NFT marketplaces are smart contracts that allow users to buy, sell, and list NFTs in a decentralized way. They function as digital storefronts where NFTs can be exchanged using smart contract logic, without the need for a centralized intermediary.

In the context of the XION ecosystem, marketplaces are critical because:

• They enable discovery and liquidity for NFTs

• They automate trustless transactions using smart contracts

• They support royalty enforcement, helping creators earn on secondary sales

• They offer customization and access control, allowing developers to tailor the buying/selling experience

By deploying a marketplace contract, developers can either create a permissionless open market for many collections or a curated shop for a single NFT series.
