# 12. Uniqueness of EGGVERSE
The final version of EGGVERSE not only lists and trades all NFTs through blockchain tracking technology, but also uses MSC (Multi SmartContract) technology that allows NFTs using any mainnet to be traded through desired cryptocurrency. We will provide services that maximize the versatility and scalability of the exchange. In addition, EGGVERSE can include more diverse contents by allowing real-life NFTs to be traded in order to solve the problem that existing NFT exchanges do not diversify products and focus only on fields such as digital art. Lastly, by providing a reverse auction system, buyer-centered NFT transactions were strengthened.
Meanwhile, as the NFT market overheats, various problems are becoming issues in the NFT market platform. In some existing NFT markets, vulnerabilities are emerging in terms of security, and recently, an incident in which about 750,000 USD was stolen by using security vulnerabilities in Opensea's front technology has occurred. In addition, the act of making copies of other NFTs without permission, the act of issuing NFTs even though they do not own content, and the act of making NFTs similar to securities occurred, causing the market to become turbid. Jack Dorsey's first tweet The Cent Exchange in the US, where NFTs were traded for about $2.9 million, also took measures to suspend trading on its own. In order to solve these issues of the existing NFT market, the real version of EGGVERSE has introduced the following original trading methods and technologies.

1. NFT compatible re-trade technology: Ultimately, more than 50 million NFTs of all mainnets such as Ethereum, Polygon, Solana, Klaytn, EOS, and Wave are tracked, and items such as price, transaction volume, and popularity are displayed on the EGGVERSE platform and automatic NFT registration without the NFT owner's separate sales registration process. It is a technology that allows buyers to freely propose bids and trade whenever the owner is satisfied with the part. In the real version of EGGVERSE, which has been commercialized and distributed, Opensea's API linkage allows the EGGVERSE exchange to trade Opensea's NFTs on its own, leading to an exponential influx of users and the supply of NFT contents.
2. Standardless technology: EGGVERSE aims to support standardless technology that goes beyond universal standardization for NFT transactions, including currently used NFT standards such as ERC721 and ERC1155 standards and other NFT standards. At the current EGGVERSE real version stage, it is possible to trade OpenC's NFTs, other exchanges' NFTs that follow the ERC721 standard, and strategically supported NFTs. Through the implementation of non-standard technology, it is possible to flexibly and continuously respond to transactions for various NFTs that increase exponentially.
3. Multi SmartContract Technology: MSC technology is a technology under development by the EGGVERSE team and is a smart contract that provides transactions through the desired cryptocurrency regardless of the type of NFT's mainnet. Currently, as the first phase of MSC, it supports Ethereum, Polygon, and Klaytn mainnet NFTs for the first time in Korea, and in the second phase, mainnets such as Solana, Flow, BSC, EOS, and Wave will be supported.
4. Real-life linked NFT: Safe real-life transactions are supported through escrow smart contract technology, and product information and authentication are provided through NFT.
5. User-centered decentralized login method support: Currently, EGGVERSE supports not only Metamask as a wallet for login, but also 60 wallets through wallet connect, as well as Coinbase and KakaoTalk's Klip wallet. We will continue to support login through an excellent decentralized wallet that many users use.
6. Pursuit of product diversity: Existing NFT markets register and sell pre-made NFTs, but EGGVERSE registers original products that have not yet been converted into NFTs. As a result, EGGVERSE's products cover all products that can be traded in real life without limitations on the types of products such as movable property, real estate, IP (Intellectual Property Rights), investment and loan, and can technically trade all products that are traded offline. can In addition, it will not only link NFTs with OpenSea Exchange, which is currently the largest NFT exchange, but will also crawl the blocks of its own mainnet to support transactions of all NFTs.
7. Prevention of fake NFT transactions: Due to the nature of NFTs, blocking the act of making NFTs through copies is not desirable from a decentralization point of view, and it is practically impossible to prevent the production of fake NFTs in the current system. However, it is technically possible to prevent trading of fake NFTs, and EGGVERSE develops an escrow smart contract to provide users with a process to review fake content to block damage to users and the market caused by fake NFTs.
8. NFT theft prevention: By omitting the centralization process that can exist on the platform, NFTs are prevented from being transmitted without authentication through the owner's wallet, thereby preventing NFT theft.
Table 3. Comparison of other NFT exchanges and EGGVERSE
Table 3 is a comparison of other NFT exchanges and the EGGVERSE platform. EGGVERSE's unique features include an escrow function for safe transactions of real-life NFTs, a reverse auction function that enables buyer-oriented transactions, a DM (Direct message) function that can improve the reliability of transactions, and a bidding smart that records all details of each transaction. Contracts and finally, there is real goods trading.
