The liquidity provision service between the same type of cryptocurrency with different key assets according to an embodiment may create a trading environment so that a single cryptocurrency has a single price in the world. As for such a liquidity supply service between heterogeneous assets, a value-fixed cryptocurrency that can be used as a base has appeared and its scope is expanding, so that the applicable range of the service is gradually expanding. Key assets may include real money and cryptocurrency, such as KRW, USDt, BTC, and ETH. In the following, the key asset may be simply referred to as'key key'.

The main contents of services that provide liquidity based on heterogeneous assets are as follows.

1) Establishment of an exchange (hereinafter referred to as ``applicable exchange'') that provides liquidity between different key axes

2) Establishment of exchanges and pairs (hereinafter referred to as'Linked Exchanges' and'Linked Pairs') that bring liquidity between different key axes

3) Bid-Ask base price between heterogeneous pillars and liquidity limit reflected in applicable exchanges

4) Provide liquidity based on safety margin

5) Real-time liquidation according to transaction

6) Securing the stability of liquidity supply through continuous risk management

1) Establishment of an applicable exchange that provides liquidity between different key axes

The applied exchange to which liquidity is supplied may correspond to an exchange to which a service providing liquidity is applied based on heterogeneous stock assets according to an embodiment. For example, the applicable exchange may correspond to a cryptocurrency exchange that trades cryptocurrency ETH in won (KRW), which is a key asset.

In order to supply smooth liquidity to the applicable exchange and to unify the price difference of the linked pair that occurs due to different key pillars, it may be required to preemptively apply the liquidity provision service between the same type of currency with the same base. However, if the bid/ask price is sufficiently formed in the applicable exchange, it may not be required to preemptively apply the liquidity provision service between the same type of currency.

2) Linked Exchange and Linked Pair Setting

Select an interlocking pair to bring liquidity and an interlocking exchange that will serve as a standard for bringing liquidity to the interlocking pair. The linked pair may be determined as a pair of cryptocurrency and key assets, and the cryptocurrency forming the linked pair may be determined as a cryptocurrency commonly traded at the applied exchange and the linked exchange.

For example, if you want to link the liquidity of cryptocurrency C, which is traded in the BTC base market of Exchange A, to cryptocurrency C, which is traded in the Won-dollar base market of Exchange B, Exchange B is the applicable exchange where liquidity is supplied, A The exchange is an interlocking exchange that brings liquidity, and the C cryptocurrency forms an interlocking pair that is the object of providing liquidity based on heterogeneous assets.

For the safety of the deposited assets, the safety and persistence of transaction services can be included as a criterion for selecting an interlocking exchange, and the volatility of cryptocurrency and the safety of the network can be used as a selection criterion for selecting an interlocked pair.

The volatility of cryptocurrency aims to select the pair with the highest asset efficiency by conducting a back-test on the pair. Here, the backtest refers to the process of calculating the difference in price change of the same type of cryptocurrency traded as a heterogeneous asset. In addition, asset efficiency refers to the ratio of the size of the transaction price generated by the service to the size of the asset required to supply the service. The size of the transaction price is linked to the size of the arbitrage transaction of the service operator, which can contribute to improving the safety of the service.

If the safety of the network is high, the speed and convenience in the process of balancing the balance can increase, which can positively affect asset efficiency.

Hereinafter, the applicable exchange is an exchange that trades ETH in KRW, and the linked exchange is an exchange that trades ETH in BTC. In other words, the key asset of the applied exchange is KRW, the key asset of the linked exchange is BTC, and the applied exchange and the linked exchange trade ETH as each key asset, so the linked pair at the applied exchange is ETH/KRW, the linked exchange The interlocked pair in is ETH/BTC.

3) Set the liquidity limit reflected in the Bid-Ask base price and liquidity applied exchanges between key axes

If the applicable exchange, the linkage exchange, and the linkage pair have been selected, it is necessary to set the Bid-Ask reference price between the underlying assets for linkage. In order to provide liquidity between the same types of currencies with different bases, the Bid-Ask standard price between the base assets must be set beforehand, in order to be able to supply liquidity to the same type of cryptocurrency that is traded on the basis of different base assets. Because.

The Bid-Ask reference price between key assets is a price for buying and selling one key asset as another, and can be determined by the supply and demand of the market in which the key asset is traded. In a pair of base currency and counter currency, the Bid-Ask base price is the Bid base price, which is the price of the counter currency to buy the base currency of a specific unit, and the relative to sell the base currency of a specific unit. It consists of the Ask base price, which is the price of the currency. FIG. 1 is a diagram for explaining the Bid-Ask reference price. When the reference currency is Euro (EUR) and the counter currency is Dollar (USD), the Bid-Ask reference price is displayed. Referring to FIG. 1, the buying price of 1 euro is 1.0661 dollars, and the selling price of 1 euro is 1.0664.

The Bid-Ask reference price can be defined as an effective price that can be actually traded. If the present price of the ratio between the existing assets (e.g., the present price of BTC/KRW, USDt/KRW) is used instead of the Bid-Ask standard price based on the effective price, the settlement between the existing assets will not be properly performed and stable real-time liquidation will not be achieved. The likelihood is very high, which is a factor that can negatively affect the smooth supply of liquidity.

The Bid-Ask reference price calculated by the bank and the Bid-Ask reference price calculated in the embodiment are similar only to promulgating the difference in the Bid-Ask reference exchange rate between currencies, and their purposes and principles are different. For example, the Bid-Ask base price calculated by the bank is for the purpose of realizing the exchange rate, but the Bid-Ask base price calculated in the embodiment is the same as the supply of smooth liquidity in the service providing liquidity based on heterogeneous assets. It aims to unify the price of cryptocurrency into a single price within a certain range. Accordingly, after setting the liquidity limit, the Bid-Ask reference price is not calculated, but the size of the key asset that can be subsequently liquidated after the Bid-Ask reference price is calculated.

2 is an example of an order screen used to exchange BTC base assets and KRW base assets with each other. More specifically, FIG. 2 shows an example of an order book using BTC as a base currency and KRW as a counter currency under a trading environment between key assets. Shows the trading volume per quote at each quote price. The transaction volume per ask price is the amount in which the base currency is being traded at the corresponding quote price, and can be expressed in units of the base currency. For example, referring to FIG. 2, the amount of BTC being bought at 12872,000 won per 1 BTC is 1.2 BTC.

The order of calculating the Bid-Ask reference price between key assets in the trading environment between key assets as shown in FIG. 2 is as follows.

Set the level of safety margin for smooth liquidity supply in the service. The safety margin can be set automatically according to a specific criterion or set to a predetermined value. For example, when the applied exchange and the linked exchange are determined, the safety margin may be determined according to the fee of the linked exchange and the fee of the applied exchange.

For example, if 0.35% is set as the safety margin, half of this, 0.175%, is calculated by adjusting the most preferred bid price (201) and the highest bid price (202) in the trading market between key assets to calculate the Bid-Ask base price between key assets. Used to do. Here, 0.175% can be used to cover fees, slippage, etc. incurred to balance the imbalance between the underlying assets resulting from the liquidity supply.

In FIG. 2, when the safety margin is set to 0.35%, the Ask reference price is 12,952,000*(1+0.00175) = 12,974,666 won by additionally increasing the highest priority bid price (201), and the Bid price is the highest priority bid price (202). It is calculated as 12,872,000*(1-0.00175)=12,849,474 won, which is further downgraded.

After the Bid-Ask base price has been calculated, the size of liquidity provision can be limited by clarifying the size of the underlying asset that can be substantially liquidated.

In Figure 2, 1.35 BTC exists between 12,872,000 won in the highest priority bid price (202) and 12,849,474 won in the bid price, and 1.35 BTC exists between 12,952,000 won in the highest priority bid price (201) and 12,974,666 won in the Ask base price. In this case, the size of the reserve assets that can be liquidated for each sell and buy is calculated as 1.35 BTC. The size of the reserve assets that can be liquidated can be a limit on the liquidity provided to the linked pair.

The status of the order book for the linked pair of the linked exchange and the status of the order book between key assets are constantly changing, so it is necessary to collect near real-time data for smooth liquidity supply.

4) Provide liquidity based on safety margin

After the pair selection of the linked exchange and the Bid-Ask base price calculation, the total amount of linked pairs brought from the linked exchange can be determined according to the size of the underlying assets that can be liquidated.

Through this, only the number of linked pairs, limited to the size of the base assets that can be liquidated, is reflected in the order book of the applicable exchange, thereby minimizing the risk of open positions in real-time liquidation between key assets. The open position risk refers to the risk of an asset imbalance due to the inability to liquidate between the underlying assets after the order from the applicable exchange and the order from the linked exchange are submitted.

3 is an example of an order screen used to trade ETH cryptocurrency as a BTC base asset in a linked exchange. More specifically, FIG. 3 shows an example of an order book of an interlocked pair (ETH/BTC) in an environment in which ETH cryptocurrency is traded as a BTC base asset. And the transaction volume per quote at each quote.

When the order book status of the linked pair in the linked exchange according to an embodiment is as shown in FIG. 3, the order of determining the total amount of linked pairs brought from the linked exchange according to the size of the base asset that can be liquidated is as follows.

In the linked exchange, the amount of BTC converted by converting the transaction volume of ETH in the order book of the linked pair in BTC is accumulated for each order type (sell, buy), and the cumulative BTC conversion quantity is calculated. For quotes where the cumulative BTC conversion quantity does not exceed the size of the base asset that can be cleared, the trading volume of the linked pair is determined by the applicable exchange by reflecting the trading volume of the linked pair on the linked exchange, and the cumulative BTC conversion quantity is the amount of the base asset that can be liquidated. For quotes that do not exceed the size, the trading volume of the linked pair can be determined at the applicable exchange with a predetermined value.

The BTC conversion quantity is a value calculated by multiplying each bid price by the transaction volume per bid price. The cumulative BTC conversion quantity is calculated by cumulatively summing the BTC conversion quantity in the direction from the highest order price to the increase in the ask price when the order type is sell.If the order type is buy, BTC conversion in the direction from the highest priority bid price to a decrease in the bid price. It is calculated by accumulating the quantity.

Referring to FIG. 3, in each column, a bid price, a transaction volume per the quoted price, a BTC conversion quantity of the quoted price, a cumulative BTC conversion quantity, and a scale-down conversion quantity are displayed. The BTC conversion quantity is calculated by multiplying the asking price by the transaction volume per the quoted price, and the cumulative BTC conversion quantity is calculated by accumulating the BTC conversion quantity in the direction of increasing the bid price from the BTC conversion quantity of the highest priority ask price (301) in the case of selling. , In the case of buying, it is calculated by accumulating and summing the BTC converted quantity in the direction of decreasing the bid ask price from the BTC conversion quantity of the highest priority purchase price 302. For example, the cumulative BTC conversion quantity (1.0764048) of the ask price (311) is the cumulative BTC conversion quantity (1.03559) of the ask price (312) that is one level lower than the ask price (0.0408148). ), and the cumulative BTC conversion quantity (0.50244124) of the bid and ask price (321) is the cumulative BTC conversion quantity (0.48917524) of the bid and ask price (322) that is one level higher than the bid and ask price. It is calculated by adding (0.013266).

Since the cumulative BTC conversion quantity does not exceed 1.35 BTC, which is the size of the base asset that can be liquidated, from the highest priority ask price to the ask price of 0.00000614 ETH/BTC. This transaction volume can be reflected in the applicable exchange. On the other hand, at the ask price of 0.00000615 ETH/BTC, the cumulative BTC conversion quantity exceeds 1.35 BTC, the size of the base asset that can be liquidated at 4.55 BTC, so the trading volume per bid price of 0.00000615 ETH/BTC cannot be fully reflected on the applied exchange. For quotes in which the cumulative BTC conversion quantity exceeds the size of the base asset that can be liquidated, a predetermined minimum value may be reflected in the transaction volume per bid price of the applicable exchange instead of the transaction volume per bid price of the linked exchange.

Referring to FIG. 3, the scale-down conversion quantity may be used to reduce the transaction volume per ask price of an order book of an interlocking exchange according to a specific ratio to reduce open positions and reflect it on an applied exchange. The scale-down ratio that reduces the transaction volume per bid price of the order book of the linked exchange by a specific ratio may be set to a value in consideration of the operating budget range. The scale-down conversion quantity shown in FIG. 3 is a value obtained by multiplying the transaction volume per bid price of the linked exchange order book by 0.8 with the scale-down ratio as 80%, and the accumulated BTC conversion quantity is calculated. Downscaling the transaction volume of the linked exchange order book is for smooth liquidity supply, and the risk of liquidity provision services can be managed by adjusting the scale-down ratio. Downscaling for risk management will be described later in 5) Securing the stability of liquidity supply through continuous risk management.

The form of the order book reflected in the applicable exchange can be calculated through the Bid-Ask base price and the size of the base asset that can be liquidated based on the calculated Bid-Ask base price. It may include calculating the quoted prices of the order book and the transaction volume per quoted price corresponding to each quoted price.

4 is a diagram for explaining a method of calculating the quotes of an order book reflected in an applied exchange according to an embodiment. Referring to FIG. 4, the selling price of the linked pair may be calculated at the applied exchange by multiplying the ask price of the linked pair by a ratio (1+0.00175) according to the Ask reference price and the safety margin at the linked exchange. In addition, by multiplying the bid price of the linked pair by the ratio (1-0.00175) based on the Bid reference price and the safety margin at the linked exchange, the applied exchange may calculate the bid price of the linked pair. It was previously explained that half of the safety margin is used in calculating the Bid-Ask base price. The other half, 0.175%, is applied to the price calculation of the linked pair traded on the applicable exchange, and can be used to cover fees and slippage when liquidating the linked pair on the linked exchange.

5 is a diagram for explaining a method of calculating a transaction volume of an order book reflected in an applied exchange according to an embodiment. Referring to FIG. 5, the size of a liquidated base asset calculated based on a Bid-Ask reference price may be used to calculate a transaction volume of an order book reflected in an applicable exchange. According to an embodiment, the volume of the order book reflected in the applicable exchange may be determined based on a scale-down ratio, a maximum value per ask price, and a minimum value per ask price.

If the calculated cumulative BTC conversion quantity does not reach the limit on the size of the base asset that can be liquidated, the transaction volume per bid price of ETH/BTC can be reflected in the order book of the applicable exchange, and the cumulative BTC conversion volume is the limit on the size of the base asset that can be liquidated. If it exceeds, the transaction volume per the quoted price can be reflected in the order book of the applicable exchange at the minimum value per quoted price.

Alternatively, if a scale down is applied to the transaction volume per bid price of ETH/BTC, and the scale-down conversion quantity calculated in FIG. 3 does not reach the limit on the size of the base asset that can be liquidated, the transaction volume per quote price of the scaled down ETH/BTC is applied. It can be reflected in the order book of the exchange, and if the scale-down conversion quantity exceeds the limit on the size of the base asset that can be liquidated, the transaction volume per quotation can be reflected in the order book of the applicable exchange at the minimum value per ask price.

If the transaction volume per bid price of ETH/BTC exceeds the predetermined maximum value per bid price, the maximum value per bid price may be reflected in the order book of the applicable exchange, and the transaction volume per bid price of ETH/BTC is per predetermined bid price. If it is less than the minimum value, the transaction volume per quotation may be reflected in the order book of the applicable exchange at the minimum value per quotation.

Alternatively, if a scale down is applied to the transaction volume per bid price of ETH/BTC, and the transaction volume per bid price of the scaled down ETH/BTC exceeds the maximum value per bid price, the maximum value per quote may be reflected in the order book of the applicable exchange, and the scale If the trading volume per bid price of downed ETH/BTC is less than the minimum value per quote price, the minimum value per quote price can be reflected in the order book of the applicable exchange.

For example, referring to FIG. 5, for the ask price 501 in which the scale-down conversion quantity calculated in FIG. 3 exceeds the size limit of 1.35, a minimum value of 10 per ask price is applied, and in FIG. For ask prices (502, 503, 505) that exceed the maximum value per ask price (502, 503, 505), a maximum value of 50,000 per ask price is applied, and for the ask price (504) where the transaction volume per ask price is less than the minimum value per ask price of 10 in Fig. 3, the minimum value per ask price is 10. Applied, the volume per order book of the applicable exchange can be determined.

5) Real-time liquidation according to transaction

Based on the order book of the interlocked pair in the applicable exchange, the user(s) can order a transaction of cryptocurrency. When an order for a cryptocurrency transaction occurs, a transaction ordered at an applicable exchange may be concluded, and a transaction for liquidation may be concluded at an interlocking exchange. When a transaction for an interlocking pair occurs in an applicable exchange, a transaction sequence for liquidation according to an embodiment may be referred to FIGS. 6A and 6B.

Referring to FIG. 6A, when a user of a service purchases 1000 ETH in KRW at an applicable exchange, the transaction sequence for liquidation is as follows.

Step 1. The ETH of the applicable exchange decreases by 1000, and the KRW corresponding to the price of 1000 ETH increases.

Step 2. Remove the open position on the linked pair by buying the same quantity as the reduced ETH on the linked exchange.

Step 3. In order to settle between the base asset KRW increased in Step 1 and the base asset BTC decreased in step 2, the base asset BTC in the amount reduced by the process of step 2 is purchased in the base asset KRW in the trading market between the base assets. An exchange that purchases the base asset BTC can use an exchange that trades the base asset BTC and KRW, and it is also possible to use the applied exchange.

Referring to FIG. 6B, when a user of a service sells 1000 ETH in KRW at an applicable exchange, the transaction sequence for liquidation is as follows.

Step 1. The ETH of the applicable exchange increases by 1000, and the KRW corresponding to the price of 1000 ETH decreases.

Step 2. Remove the open position for the linked pair by selling the same quantity as the increased ETH on the linked exchange.

Step 3. In order to settle between the base asset KRW, which decreased in Step 1 and the base asset BTC, which increased in step 2, in the trading market between the base assets, the increased amount of the base asset BTC, which was increased by the process of step 2, is sold as the base asset KRW.

When the order book transaction on the applicable exchange (hereinafter referred to as ``this order'') is concluded, the order corresponding to this order (hereinafter referred to as ``reverse order'') is processed at the linked exchange, and the key assets are settled according to the main order and reverse order. An order to be made (hereinafter,'an order to adjust an underlying asset') may be proceeded. In the process, there are cases in which you have to pay a fee for each exchange, so it is essential to understand the fee system clearly.In addition, liquidity is provided because the main order, reverse order, and order to adjust the existing assets can be separately executed. For the stability of the company, it is essential to continuously adjust the safety margin by analyzing the profit and loss for each case. In addition, in the process of liquidation, it is possible to lead to an increase in the desired asset by adjusting the ratio between the existing assets.

6) Securing the stability of liquidity supply through continuous risk management

A risk management method can be applied to services that provide liquidity based on heterogeneous assets. For example, the following six risk management methods can be applied.

1. Establishment of the size of reserve assets that can be liquidated: Risk can be managed by limiting the total liquidity applied to the linked pairs of the applicable exchange according to the size of the reserve assets that can be liquidated.

2. Scale down: By reducing the order book of the linked exchange by a certain percentage and reflecting it on the applied exchange, it is possible to manage risk by reducing reverse orders submitted to the linked exchange.

3. Maximum value per ask price: By setting the maximum value per ask price reflected in the applied exchange and limiting the size of orders submitted to the applied exchange, the risk of non-trading of reverse orders on the linked exchange can be reduced.

4. Safety Margin: Risk can be managed by adjusting the safety margin to cover slippage and fees arising from reverse orders submitted to linked exchanges and orders to adjust underlying assets.

5. Reorder: When non-trading occurs in reverse orders and stock asset adjustment orders, reorders can be submitted at specific time intervals to manage open position risk.

6. Order cap: When this order is submitted at the applicable exchange, risk can be managed by identifying the assets of the linked exchange and setting the order cap so that only orders that can be reverse ordered are submitted.

The service providing liquidity based on the above-described heterogeneous stock assets may be performed in a device such as a server. An apparatus for providing a service providing liquidity based on heterogeneous assets according to an embodiment may include at least one processor that performs the above-described service operation and a memory that stores data related to service provision.
