Stub Package for Launching a New EMP
The purpose of this repository/package is to make it easy to customize your EMP deployment. Feel free to use this repository in place or fork and customize it.
Install system dependencies
You will need to install nodejs (we recommend the latest stable version, nodejs v14, and nvm to manage node versions) and yarn.
Note: these additional dependencies are required -- you may or may not have them on your system already:
libudevlibusb
Example ubuntu installation command for additional deps:
sudo apt-get update && sudo apt-get install -y libudev-dev libusb-1.0-0-dev
Install packages
yarn
Run the deployment script on a mainnet fork
It's a good idea to try out your deployment on a fork before running it on mainnet. This will allow you to run the deployment in a forked environment and interact with it to ensure it works as expected.
Start ganache.
yarn ganache-fork your.node.url.io
In a separate terminal, run the deployment script (it defaults to using localhost:8545 as the ETH node, which is desired in this case). Note: mnemonic is optional here -- without it, ganache will use its default pre-loaded account.
node index.js --gasprice 50 --mnemonic "your mnemonic (12 word seed phrase)" --priceFeedIdentifier USDETH --collateralAddress "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2" --expirationTimestamp "1643678287" --syntheticName "Yield Dollar [WETH Jan 2022]" --syntheticSymbol "YD-ETH-JAN22" --minSponsorTokens "100"
Now you should be able to use localhost:8545 to interact with a forked version of mainnet (or kovan) where your
contract is deployed.
Run the deployment script on mainnet or kovan
node index.js --gasprice 50 --url your.node.url.io --mnemonic "your mnemonic (12 word seed phrase)" --priceFeedIdentifier USDETH --collateralAddress "0xd0a1e359811322d97991e03f863a0c30c2cf029c" --expirationTimestamp "1643678287" --syntheticName "Yield Dollar [WETH Jan 2022]" --syntheticSymbol "YD-ETH-JAN22" --minSponsorTokens "100"
Customize the script
The script should be fairly easy to read and understand. It is recommended to keep the default empParams and customize your construction parameters by passing the listed mandatory args. See the script for more details.
We encourage you to fork this repo and customize the script as you see fit!
