Decentralized Token Swapping Method with Low Slippage Point and High Liquidity
The present invention discloses a decentralized token swapping method with low slippage point and high liquidity. The present invention relates to the technical field of decentralized token exchanging, specifically, providing liquidity to a liquidity pool by a liquidity provider, depositing a X token and a Y token into the liquidity pool in an equal value ratio in a mortgage mode; providing liquidity to X maker pool and Y Maker Pool by X maker and Y maker independently. In the present invention, a Taker determines to swap from the liquidity pool or the maker pools based on a random number. The present invention can effectively reduce the swapping slippage points: if the leverage rate is n, then the slippage point can be reduced to 1/n of the Uniswap mode, and more demand can be provided. For instance, users who plan to sell one asset for another over a period of time can provide liquidity, rather than only rely on users in an equal ratio mortgage to provide liquidity.
1 . A decentralized token swapping method with low slippage point and high liquidity, characterised in that the method comprises the following steps:
providing liquidity to a liquidity pool by a liquidity provider, depositing a X token and a Y token into the liquidity pool in equal value ratio through mortgage;
providing liquidity to a X Maker Pool and a Y Maker Pool by a X maker and a Y maker independently;
wherein, the X Maker Pool records the amount of X token in the X Maker Pool, an amount of Y token in the X Maker Pool, a transaction fee rewarding pool of the X Maker Pool, an average swapping rate historically accumulated by the amount of Y token in the X Maker Pool, and an average token deposition time of the X maker in the X Maker Pool;
wherein the Y Maker Pool records the amount of Y token in the Y Maker Pool, an amount of X token in the Y Maker Pool, a transaction fee rewarding pool of the Y Maker Pool; an average swapping rate historically accumulated by the amount of X token in the Y Maker Pool, and an average token deposition time of the Y maker;
when the X maker deposit X token into the X Maker Pool, recording the deposited amount of X token and the time of the last X deposition through a contract account;
when the Y maker deposit Y token into the Y Maker Pool, recording the deposited amount of Y token and the time of the last Y deposition through a contract account;
a Taker determines to swap from the liquidity pool or swap from the maker pools based on a random number.
2 . The decentralized token swapping method with low slippage point and high liquidity according to claim 1 , characterized in that,
when the Taker swaps from the liquidity pool, a change in demand causes a fluctuation of the price, and a reasonable price is formed through the operation and competition from Takers in different directions;
when the taker swaps from the X Maker Pool or the Y Maker Pool, the price is based on the current price of the liquidity pool,
when the taker swaps Y for X, the amount of X token in the X Maker Pool decreases, the amount of Y token in the X Maker Pool increases, and in the meanwhile the transaction fee rewarding pool of the X Maker Pool is accumulated;
when the taker swaps X for Y, the amount of Y token in the Y Maker Pool decreases, and the amount of X token in the Y Maker Pool increases, and in the meanwhile the transaction fee rewarding pool of the Y Maker Pool is accumulated.
3 . The decentralized token swapping method with low slippage point and high liquidity according to claim 2 , characterized in that:
when the X maker deposits X into the X Maker Pool, and withdraws swapped currency Y form a Y pool in the X Maker Pool, the price is based on the average swapping rate historically accumulated by the amount of Y token in the X Maker Pool, a required transaction fee is related to the deposition time;
wherein if the deposition time is less than the average token deposition time of the X maker, a transaction fee is required to be paid, and the transaction fee adds into the transaction fee rewarding pool of the X Maker Pool;
wherein if the deposition time is more than the average token deposition time of the X maker, a transaction fee is obtained, and the transaction fee is taken from the transaction fee rewarding pool of the X Maker Pool.
4 . The decentralized token swapping method with low slippage point and high liquidity according to claim 3 , characterized in that:
when a value of the asset swapped and completed in the X Maker Pool or the Y Maker Pool is not as high as an off-site value, the X maker or the Y maker is replaced.
5 . The decentralized token swapping method with low slippage point and high liquidity according to claim 4 , characterized in that:
the method further includes a timing module, and the time module starting a timing when the X Maker Pool or the Y Maker Pool is replaced,
when the timing of the time module is less than a preset minimum duration, the X Maker Pool or the Y Maker Pool is not allowed to be replaced,
when the timing of the time module is larger than the preset minimum duration, the X maker or the Y maker is allowed to trigger a switch.
6 . The decentralized token swapping method with low slippage point and high liquidity according to claim 5 , characterized in that:
when the swapping in one of the mark pools reaches a predetermined ratio, and when a next maker starts to perform deposition, the mark pool is switched to a new mark pool, the newly deposited X or Y is automatically deposited in to the new mark pool, and the average swapping rate is re-accumulated again,
and the makers who deposited X or Y into the previous mark pool can only withdraw X or Y from the previous mark pool.
7 . The decentralized token swapping method with low slippage point and high liquidity according to claim 6 , characterized in that: the predetermined ratio is 90%.
