MetaPlace – NFT Marketplace
MetaPlace — NFT Marketplace
Overview
MetaPlace is the NFT marketplace of the Meta Whale ecosystem — a universal platform for trading all types of digital assets within a single contract space. Educational certificates, course programs, referral system slots and levels, as well as metaverse objects are issued as ERC-721 / ERC-1155 tokens, turning every achievement or resource into a liquid, tradable asset.
Users can freely trade NFTs on MetaPlace or external marketplaces (OpenSea, Rarible, etc.), and use them across the metaverse — from avatar customization and land ownership to education-based credentials.
Functionality
MetaPlace supports a full trading stack:
Ask Orders (Sell Orders): NFT owners list tokens with price and expiration; orders are signed off-chain (EIP-712) and executed on-chain when a buyer accepts.
Bid Orders (Buy Orders): Buyers submit signed bids or deposits; sellers can accept bids directly through smart contracts.
Auctions: Multiple formats are supported to fit different asset types:
English Auction: price increases with each bid (for rare items and unique certificates).
Dutch Auction: price decreases until first purchase (for mass drops like clothing or land plots).
Sealed-Bid Auction: hidden bids revealed at the end (for high-value NFTs).
Reserve Price Auction: minimum price must be reached (for premium assets).
All transactions are secured by smart contracts with escrow mechanics, ensuring transparency and fairness.
Ecosystem Role
MetaPlace extends the Meta Whale ecosystem by:
Turning ecosystem progress and achievements into liquid NFTs.
Enabling secondary trading of ecosystem assets with built-in royalty support (ERC-2981 standard).
Supporting in-ecosystem utility — NFTs can be applied in Meta Whale metaverse environments, educational flows, and gamified programs.
Ensuring CES token circulation — all transactions under the hood are settled in CES, even when users pay in other supported currencies, strengthening token demand.
