Project Description

In the MVP phase EveryFin only works on the avalanche network and includes 3 big parts.

• Trading
• Stacking
• Landing

EveryFin does not develop own exchange, staking and lending mechanisms, only connects to existing smart contracts. And takes a small commission for some operations.

As an example with trading: We build a functionality on the frontend similar to Trader Joe's XYZ or Uniswap. When making an exchange, the funds first go through our proxy contracts where the commission is charged, and the remaining amount of funds goes to TraderJoeV2Router02 Address

The basic architecture scheme looks like:

User UI -> EveryFin Proxy contracts -> Traget contract

We are currently working on a proxy contract for trading part using Trader Joe's XYZ. And this part is in active development and is not finished yet

Tech Stack

Smart Contracts: Solidity

Tests/Deploy scripts: Node, Hardhat, Ganache, Mocha, Chai

Launch

Clone the project

  git clone https://git.machinadev.com/everyfin/EveryFin_Contracts

Go to the project directory

  cd EveryFin_Contracts

Install dependencies

  npm install

Running Tests

The testnet network (fuji) does not contain all the trading pairs we need, and in order not to spend a lot of real money on development we use a local fork of the main avalanche network.

You can set the block number you need or add/modify the necessary networks in the file hardhat.config.js

To run the test:

  npm run test

Deployment

Also you can deploy to contracts to the avalanche mainnet network and test all using Metamask, Remix or any other tool

 npm run deploy:avalanche

Or you can deploy to avalance testnet (fuji), but for this change the adress of TraderJoeV2Router02 and WAVAX addresses in deployment files.

npm run deploy:fuji

Environment Variables

You can run this project with your variables, just add it to your .env file (look .env.example)

MNEMONIC

SNOWTRACE_API_KEY

INFURA_KEY

The project will also run without .env, The project code, if there is no .env, will use some of its own safe variables

Roadmap

• Trading functional using proxy contracts on Avalanche network, using Trader Joe XYZ

• Staking functional using proxy contracts on Avalanche network, using Benqi.fi Staking

• Lending functional using proxy contracts on Avalanche network, using Benqi.fi Lending
