AMM is comprised of two smart contracts AMMExchange and LeverageTrade. This project uses the hardhat framework for contract development and deployment.
The AMMExchange contract defines an exchange supporting the swapping of ERC20 tokens (TWD and USD).
- addLiquidity: adds liquidity to the pool
- exchange: exchange an asset for another. When passing
pathas an the second argument to this function, the fist index is the input token and the second (last) index is the output token.
The LeverageTrade contract is an implementation of a Leverage AMM exchange. It supports depositing any ERC20 token as collateral and the leverage trading of any ERC20 token and Ethereum.
- depositToken: deposit collateral to the system. Ensure allowance has been set for the contract.
- getRemAccountValue: retrives the remaining account value for a pool
- openLongPosition: opens a leveraged position; buys ETH
- openShortPosition: opens a leveraged position; sells ETH
- getAmountOut: input the amount of asset A and the leverage, and it returns the amount of asset B you will get after exchange
- getAmountOut2: input the amount of asset B you want to exchange and the leverage, and it returns the amount of asset A you should provide
- getPositions: view your leveraged positions for a set pool

$ git clone git@github.com:Kifen/AMM.git
$ cd AMM
$ npm install
To run test, npm run test
These contracts have been integrated to oneclickdapp. To test via a GUI, make use of:
The USD Coin Dapp and TWD Token Dapp can be used to interact with the pool tokens for the AMMExchange; especially minting and setting allowances and approvals.
