Hereinafter, embodiments of the present invention having the above-described features will be described in more detail with reference to the attached drawings.

In the system for providing unlisted coin trading platform services according to an embodiment of the present invention, a trading app for buying and selling unlisted coins is installed, and a first electronic wallet 111 that stores virtual assets exchanged at an equivalent price for the amount to be purchased is installed. A buyer terminal 110 is installed, which transmits purchase information of the purchase quantity and purchase price for a specific unlisted coin, issues unlisted coins, and a trading app for buying and selling unlisted coins is installed, and a specific quantity of unlisted coins to be sold is installed. The stored second electronic wallet 121 is installed, and the unlisted coin selling server 120 transmits the selling information of the selling quantity and selling price for the unlisted coin, and receives, verifies and matches the buying information and selling information, It is transmitted to the buyer terminal 110 and the unlisted coin selling server 120, respectively. When purchase approval information is received from the buyer terminal 110, the total purchase amount of the first electronic wallet 111 is transferred to the sale of the second electronic wallet 121. Determine whether the total amount is exceeded, transfer unlisted coins from the second electronic wallet 121 to the first electronic wallet 111, and transfer virtual assets from the first electronic wallet 111 to the second electronic wallet 121. , including the unlisted coin trading platform server 130, the aim is to minimize risk when trading unlisted coins and ensure safe trading.

Hereinafter, with reference to FIGS. 1 and 2, the unlisted coin trading platform service provision system of the above-described configuration will be described in detail as follows.

First, the buyer terminal 110 is a terminal that participates in unlisted coin trading by going through an authentication process and registering on an unlisted coin trading platform. It is equipped with and installed a trading app or trading app for buying and selling unlisted coins, and is a terminal that participates in unlisted coin trading. A first electronic wallet 111 such as Metamask, which stores virtual assets exchanged at an equivalent amount, such as virtual currency or NFT (Non-Fungible Token), is installed, and purchase information of the purchase amount and purchase amount for a specific unlisted coin is installed. It is transmitted to the unlisted coin trading platform server (130).

Here, the buyer terminal 110 is exemplified as paying with virtual assets of the first electronic wallet 111 when purchasing unlisted coins, but it may also be possible to make payment by replacing it with cash.

Meanwhile, only when the exchange value of the virtual asset of the first electronic wallet 111 is verified, evaluated, and recognized by the unlisted coin trading platform server 130, the unlisted coin trading platform server 130 By allowing participation in trading on unlisted coin trading platforms, the reliability of unlisted coin trading platforms can be increased.

Next, the unlisted coin selling server 120 is a component that issues and sells unlisted coins. It registers on the unlisted coin trading platform through an authentication process, and a trading app or trading app for buying and selling unlisted coins is installed, and the person who wishes to sell is installed. A second electronic wallet (121), such as MetaMask, in which a certain amount of unlisted coins are stored, is installed, and the sale information of the sale amount and sale price for the unlisted coins is transmitted to the unlisted coin trading platform server (130).

Next, the unlisted coin trading platform server 130 receives purchase information from the buyer terminal 110 and sell information from the unlisted coin selling server 120, verifies the authenticity of the purchase information and sell information, and verifies the purchase information. The selling information is matched and transmitted to the buyer terminal 110 and the unlisted coin selling server 120, respectively.

Here, the buyer's personal information included in the purchase information and the operating entity information included in the sale information can be encrypted, transmitted to the unlisted coin trading platform server 130, and decrypted to protect against external hacking, etc.

In addition, when the unlisted coin trading platform server 130 receives purchase approval information from the buyer terminal 110, it determines whether the total purchase amount of the first electronic wallet 111 exceeds the total sale amount of the second electronic wallet 121. Thus, the unlisted coin is transferred from the second electronic wallet 121 to the first electronic wallet 111 and stored, and the purchase price for the unlisted coin is transferred from the first electronic wallet 111 to the second electronic wallet 121. Send and store the corresponding virtual asset.

In this way, the unlisted coin trading platform server 130 verifies the authenticity of the buying and selling information and identifies virtual assets, false electronic wallet accounts, and false trading information resulting from manipulation of false digital records by internal forgery or external hacking. By identifying forgery and alteration, it is possible to block false transactions between virtual assets and unlisted coins.

Meanwhile, the unlisted coin transaction platform server 130 calculates the conversion value into cash through the valuation module 131, and unlists the virtual assets of the first electronic wallet 111 and the second electronic wallet 121. By evaluating and verifying the value of the coin, the purchase transaction is approved by determining whether the purchase price and purchase price according to the value of the virtual asset and unlisted coin are appropriate or justified prior to the transaction. If not, the purchase transaction is approved at the buyer terminal (110 ) and the unlisted coin trading platform server 130 can also be notified so that they can be used for trading transactions.

Here, the valuation module 131 evaluates the virtual asset of the first electronic wallet 111 through the real-time price of the reference exchange, and calculates the standard price according to the business agreement concluded between the unlisted coin issuer and the trading platform operator. Through this, you can evaluate the unlisted coins of the second electronic wallet (121).

In addition, the unlisted coin trading platform server 130, through the verification module 132, connects the first electronic wallet 111 corresponding to the buyer terminal 110 during the previous transaction on the relevant trading platform or another trading platform with which a business agreement exists. By determining whether the buyer's personal information and the second electronic wallet (121) corresponding to the unlisted coin selling server (120) and the operating entity information are blacklisted, the trading transaction participants are verified to limit or fundamentally block the trading transaction to reduce risk. You can also minimize the burden and ensure safe transactions.

In addition, the verification module 132 determines the shares of listed stocks, unlisted stocks, assets, intellectual assets, etc. of the issuing company corresponding to the unlisted coin selling server 120, corresponding to the total amount of unlisted coins to be sold or to be sold. By setting part or all of the coins as collateral and registering the total amount of unlisted coins corresponding to the collateral ratio for sale, the exchange value of the unlisted coins is secured, thereby limiting the indiscriminate issuance of unlisted coins whose exchange value is not recognized. , blocks the consignment or registration of false sales volume such as scam coins, and even after the transaction of unexpected false sales volume is performed, the purchase money is returned to the buyer on the premise of collateral and the collateral is recovered in the corresponding proportion to protect the buyer. By protecting it, it can also increase the reliability of the unlisted coin trading platform.

In addition, the unlisted coin trading platform server 130 sets and registers the total sale volume of unlisted coins in accordance with changes in the value of collateral by the verification module 132, thereby limiting excessive or indiscriminate issuance of unlisted coins. It is also possible to minimize the devaluation of unlisted coins.

In addition, the unlisted coin trading platform server 130 links and transmits temporary short-term temporary ownership of the shares of the issuing company as a certain percentage corresponding to the purchase price of the unlisted coin purchased to the buyer terminal 110 for verification. It is also possible to compensate for the buyer's damage when trading unlisted coins with no market value, such as scam coins that were not filtered at the time of registration.

Meanwhile, the unlisted coin selling server 120 that issues unlisted coins was previously exemplified as the selling entity, but the seller terminal 140 may be included to enable peer-to-peer transactions (P2P coin trading) for unlisted coins.

In other words, a trading app for buying and selling unlisted coins is installed on the seller's terminal 140, a third electronic wallet 141 such as MetaMask that stores a specific quantity of unlisted coins to be sold is installed, and the selling amount for the unlisted coins is installed. The sale information of the and sale money can be transmitted to the unlisted coin trading platform server (130).

In addition, the unlisted coin trading platform server 130 receives purchase information and sell information, verifies and matches them, and transmits them to the buyer terminal 110 and the seller terminal 140, respectively, and receives purchase approval information from the buyer terminal 110. Upon receipt, it is determined whether the total purchase amount of the first electronic wallet (111) exceeds the total sale amount of the third electronic wallet (141), and the unlisted coin is transferred from the third electronic wallet (141) to the first electronic wallet (111). Then, the virtual asset is transferred from the first electronic wallet 111 to the third electronic wallet 141, and as mentioned above, the verification module 132 is used to transmit the virtual asset corresponding to the buyer terminal 110 at the time of the previous transaction. It is also possible to determine and verify whether the 1st electronic wallet 111 and the buyer's personal information and the 3rd electronic wallet 141 corresponding to the seller's terminal 140 and the seller's personal information are blacklisted.

For example, the unlisted coin transaction platform server 130 calculates the conversion value into cash through the valuation module 131, and unlists the virtual assets of the first electronic wallet 111 and the third electronic wallet 141. By evaluating and verifying the value of the coin, the purchase transaction is approved by determining whether the purchase price and purchase price according to the value of the virtual asset and unlisted coin are appropriate or justified prior to the transaction. If not, the purchase transaction is approved at the buyer terminal (110 ) and the seller's terminal (140) can be notified so that it can be used for sales transactions.

Here, the valuation module 131 evaluates the virtual asset of the first electronic wallet 111 through the real-time price of the reference exchange, analyzes the change in transaction price and issuance amount during the previous transaction of the corresponding unlisted coin, and analyzes the third electronic wallet ( 141) unlisted coins can be evaluated.

In addition, the unlisted coin trading platform server 130, through the verification module 132, connects the first electronic wallet 111 corresponding to the buyer terminal 110 during the previous transaction on the relevant trading platform or another trading platform with which a business agreement exists. By determining whether the buyer's personal information, the third electronic wallet (141) corresponding to the seller's terminal (140), and the seller's personal information are blacklisted, the transaction participants are verified to limit or fundamentally block the transaction to reduce the burden of risk. It can also be minimized to ensure safe transactions.

In addition, during peer-to-peer transactions for unlisted coins through the unlisted coin trading platform server 130, the unlisted coin trading platform server 130 exchanges virtual assets according to previous transactions on the relevant trading platform or other trading platforms with which it has a business agreement. By verifying the history of changes in value and the amount of unlisted coins held, rapid transaction approval, transaction restrictions, or transaction blocking can be carried out during the subsequent Nth transaction, and virtual assets corresponding to the corresponding sale amount of the Nth transaction are performed. It is possible to block false transactions between virtual assets and unlisted coins by verifying whether they hold and unlisted coins respectively.

In addition, as mentioned above, the unlisted coin trading platform server 130 issues a certain percentage corresponding to the purchase amount of the unlisted coin purchased from the first buyer terminal 110 even during the Nth individual transaction. Stability can be provided by linking and transmitting temporary short-term temporary ownership of the company's shares to the secondary buyer terminal 110, thereby compensating for damage to subsequent buyers during the Nth transaction.

Meanwhile, the unlisted coin trading platform server 130, through the auction module 133, sells or purchases by auction method or reverse auction method between the buyer terminal 110 and the unlisted coin selling server 120 or the seller terminal 140. You can also have it done.

In addition, the unlisted coin trading platform server 130, upon request from the unlisted coin selling server 120 or the seller terminal 140, provides cash, gift certificates, travel vouchers, exchangeable points, or You can also provide points for purchasing products.

In addition, when registering an unlisted coin with no previous transaction history from the unlisted coin selling server 120 or the seller terminal 140 to the unlisted coin trading platform, the unlisted coin trading platform server 130 registers and sells the corresponding Similar to the theme of unlisted coins, NFC coin, Oracle coin, IoT coin, smart contracts coin, DeFi coin, simple payment platform coin, game market coin, advertising industry coin, data storage Accidents or crimes of unlisted coins such as service coins, decentralized exchange coins, computing power rental service coins, authentication services, coins, content production and brokerage coins, platform coins, SNS content coins, Bitcoin group-related coins, and Ethereum group-related coins. Analyze risks such as relevance to limit sales volume or decide whether to register, and analyze coin transaction information such as trading volume and issuance volume of unlisted coins similar to the theme, market capitalization, and price information (price fluctuation trends, etc.) to determine sales volume. can be determined, and through this, if the trend of the theme passes, there is no marketability for the technology of the theme, or the size of the trading market for the theme is reduced, the unlisted coin trading platform server 130 provides financial By selecting healthy or marketable unlisted coins and registering them for sale, you can encourage safer transactions for buyers.

In addition, the unlisted coin trading platform server 130 provides a deposit or rental service for part or all of the unlisted coins from the buyer terminal 110 who purchased the unlisted coins through the unlisted coin trading platform, thereby providing an unlisted coin trading platform. The server 130 receives unlisted coins from the buyer terminal 110, stores them in the corresponding electronic wallet, and provides interest according to the deposit period or rental period to the buyer terminal 110, thereby facilitating simple holding of the buyer terminal 110. In addition to profits and losses due to market fluctuations, additional interest income can be provided to increase the utilization rate of the unlisted coin trading platform.
