A Simple L2 Zksync AMM

This is a simple AMM which stores two tokens and it's balance in the smart contract and exposes the functions to withdraw, swap. This doesn't have any fee or incentive mechanism. It based on the simple formula which is used by the Uniswap protocol i.e. p*q = K (Where K is the total liquidity in the pool and p and q the token1 and token2 respectively) Deployed at 0x00D15247D811e5E1E2476078596De53C68754eee (zksync testnet) test account used (0xDEcc3156Bd9826a0034D829C35Dc3679Be5ac529)

Frameworks

• Solidity (v0.8.0)
• Hardhat (for compiling, deploying and testing)
• Node (v16.0.0)

Steps to run the project

1. Clone the project and install the dependencies (make sure you have latest node and hardhat installed)

yarn install 

2. Add your private key in deploy.ts file and your ETH network URL in hardhat.config.ts

const wallet = new Wallet("<YOUR_PRIVATE_KEY>"); //deploy.ts

zkSyncDeploy: {
    zkSyncNetwork: "https://zksync2-testnet.zksync.dev",
    ethNetwork: "", // Can also be the RPC URL of the network (e.g. `https://goerli.infura.io/v3/<API_KEY>`)
  }

3. Compile the contracts (to see if they are successfully compiled check if "artifacts-zk" and "cache-zk" folders are created in your repo

yarn hardhat compile

4. Deploy the contract. Make sure you have enough ETH for the transactions in your wallet for Goerli testnet.

yarn hardhat deploy-zksync
