This project manages the fee computations for requests on the MUON network.

##How it works A group of trusted entities is carefully chosen to operate this fee server and oversee the fee processing. These entities run the "fees backend" project on dedicated servers, and their addresses are included as fee service providers within the Muon Core's configuration.

The rationale behind having multiple servers, rather than a single one, is to enhance trustworthiness and reduce reliance on a single endpoint.

Users can deposit fees into different contracts on various blockchain networks. The list of all contracts that need to be checked to determine the total balance of a user is defined in the URL 'config/contracts.json'.

First, run npm i to install the project's dependencies. Make a copy of the .env.example file and rename it to .env.

In the .env file, Set the MongoDB connection in the MONGODB_CS variable and establish the appropriate Redis connection by providing the REDIS_URL.

Then place the signer's private key in the SIGNER_PK field and its corresponding public key in the SIGNER field.

Inside the MUON node's global configuration file, located at config/global/default.net.conf.json, there's an object dedicated to the fee server configuration:

"fee": {
    "endpoint": "__URL_TO_FEE_SERVER__",
    "signers": [
      "__SIGNER_PUBLIC_KEY__"
    ]
},

The address for the fee server instance needs to be set within this object, and the same signer's public key must also be added here.

##Running fee server You can initiate this project by executing the npm start command.
