4.6. Built-in Exchange

​

LM provides an NFT trading market. This market is the main function of LuckyMeta, which is used to help players conduct NFT transactions between players, and between the vault protocol and players.

Market transactions between players use auctions to trade NFTs.

• If there is no bid within a fixed time at the end of each auction, it means the last bidder has successfully bid.

• After the auction, the successful bidders will receive the NFT obtained from the auction, and the bidders will receive their assets back.

LM's NFT market contract is connected to the OpenSea market, and players can choose to trade their NFTs in OpenSea at the same time.

LM provides a fast exchange, which is connected to DEXs such as Uniswap and QuickSwap by means of protocol calls to help players buy and sell digital assets such as LMG and LMT in DAPP with one click.

LM's built-in exchange serves third-party developers, helping third-party developers issue and trade their tokens within the LM system and provide market depth.

The Vault Protocol, controlled by the DAO, is an important player in the built-in exchange. The first batch of mystery chest in the entire market was created by the Vault Protocol through a whitelist to help players mint in the market. The protocol will use the vault assets to intervene in the prices of NFT, LMT, LMG, third-party tokens and other assets in the secondary market through a set of coding rules.
