# Ecological Closed Loop

**Design of multiple "strong destruction deflation" protocol**

1\. In the multielement ecological circulation system of MetaFinance,

The mechanism with multiple "strong deflation destruction" is cleverly designed, so that the total MEFI token circulation continues to decrease and deflation destruction is triggered by the participation of users.

2.In the MetaFinance platform system, under the circumstance of reduction in new users and aggregate orders and in the mechanism with multiple "strong deflation destruction", the on-chain behavior of only existing participating users will also make the total MEFI circulation continue to decrease.

**Destruction mechanism and path:**

**1.**&#x31;00% is destroyed directly when a user redeems the USDTs at the platform's current MEFI value.

**2.**&#x33;% of the Swap trading fee on the decentralized exchange is destroyed directly.

**3.**&#x4D;echanism for the destruction of MEFI tokens as the invitation reward: When there is no superior recommender or the superior recommender participates in Hand game PK less than five times, the redundant MEFI tokens for rewards will be directly destroyed.

**4.**&#x54;he MEFI token destruction mechanism when receiving the invitation reward: Only 70% invitation reward can be received and 30% of the invitation rewards should be given to the superior recommender. The MEFI tokens of 30% reward are directly destroyed if there is no superior recommender.

**5.**&#x4D;EFI token destruction mechanism when receiving the MetaFinance-NFT benefits and rewards: Only 80% of NFT interests and rewards can be received and the rest 20% should be given to the superior recommender holding NFT. 20% will be directly destroyed if there is no superior recommender.

**6.**&#x57;hen a user participates in NFT prop card pledge mining, the system forces MEFI tokens to be sold (and destroyed) according to the current price of MEFI each time the user withdraws the income, and the user obtains the stablecoin USDTs.

**7.**&#x54;he MEFI tokens consumed when activating the NFT prop card for "card collection mining" are directly destroyed.
