The Altura marketplace

The Altura marketplace was carefully designed to make it easy for all different types of gaming projects to be monetized on our platform. ### Overview **Blockchain Support** The Altura Marketplace, like the rest of the Altura platform, supports seven different blockchains: Ethereum, BNB Smart Chain, Polygon, Arbitrum, Optimism, Fantom, and Avalanche. **Seaport Contract** Altura leverages the Seaport marketplace contract, developed by OpenSea, which is the most secure & gas-efficient marketplace engine. It is, on average, 30% more gas efficient than other marketplace engines **Order-book system** NFTs, with a supply greater than 1 (ERC1155 only), can have multiple listings. When listing an NFT, users can specify the currency, price & amount of the NFT they want to sell. **Offers system** Buyers can make an offer to buy an NFT at a specific price (and currency), and can set when their offer expires **Currencies: native-chain coin + stablecoins** Users can list their NFTs in the native coin of the chain (ETH, BNB, MATIC, FTM, AVAX) and stablecoins on that chain (USDC, USDT & BUSD (on BSC)) **Notification system** Receive notifications when you sell an NFT (receiving notifications for when an NFT you own receives an offer coming soon). **Likes & views** Users can like NFTs and view their liked NFTs on their profile pages.
