Klaytn-DEX Project

Open-source DEX for Klaytn. This repository is for smart-contracts part of DEX.

Deploy

Before deployment, please, set up all required parameters in your .env file described in the .env.example.

Using command line

To deploy all DEX Smart Contracts, please run

npx hardhat run scripts/deployDEX.ts --network `network`

command with the specified network argument. In case of hardhat network deployment, there is no need to provide any additional parameters. The network should be configured in your hardhat.config.ts file in HardhatUserConfig.networks section. Please, refer to the Hardhat Networks Configuration guide for more information. Currently, the following networks are already configured:

• hardhat (default)
• baobab (Klaytn Baobab Testnet)

Example:

npx hardhat run scripts/deployDEX.ts --network baobab

Example (default hardhat network):

npx hardhat run scripts/deployDEX.ts

Using Docker

Docker and docker-compose are required for this step.

You can see the following in docker-compose.yaml. Please update DEX_NETWORK_NAME you want to deploy.

version: "3.7"

services:
  app:
    build: .
    volumes:
      - ./.env:/app/.env
      - ./deployments:/app/deployments
    environment:
      DEX_NETWORK_NAME: baobab

docker-compose up --build

Tests

Before running tests, please, provide the following parameters in a .env file: MNEMONIC, FORKING(true/false) and FORKING_URL (in case of FORKING is true). To run all unit tests, please run

npx hardhat test

Forking

You can start an instance of Hardhat Network that forks the specified network via its Archive Node RPC endpoint. It will simulate having the same state as the network, but it will work as a local development network. Please, refer to the Hardhat Forking guide for more information. To use this feature you need to set up FORKING parameter as true and provide FORKING_URL in your .env file. After setting up forking parameters you can run all the tests on the forked network

npx hardhat test

or launch the deployment script

npx hardhat run scripts/deployDEX.ts

to simulate the deployment process to the forked network.
