There are three main components of the smart contract as outlined below

DMM Router:

• The main smart contract that serves all users’ and providers’ transactions.

• There are three main functions that will be executed and written in the DMM Router

  which are:

  • to add liquidity

  • to remove liquidity

  • to swap tokens

• For the first time when a user uses a DMM Router, the user has to approve the router to transfer tokens to execute transactions; future transfers will not need this approval

• To add liquidity, the amount of the token pairs will be added to the pool and users will receive LP tokens back. This LP token is called EF-DMM-LP token. The fee for swapping will be shared between liquidity providers and Evry.Finance decentralized exchange platform at a ratio 1 to 4/

• To remove liquidity and retrieve the tokens back from liquidity pools, users will remove the EF-DMM-LP token and transfer back to their wallet address the amount of tokens they added. The price will be adjusted to the price level at the time of execution.

DMM Factory:

• Allows for the creation of pools. Admins are able to create pools for traders to swap tokens and for providers to provide the liquidity of the pool. Only authorized addresses with admin permissions will be able to create pools.

• Allows for Fee configuration. The swapping fee and governance fee can be configured only by authorized addresses. Changes are not immediately and any change will be notified to all users including liquidity providers, and trades. Changes will only be executed after some time has passed.

User management

• A super admin will be assigned to the deployed contract to control all liquidity pools and allow for configuration and other functionality of the system.
