Jumping off point for launching a new EMP

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 v12 (we recommend nvm to manage node versions) and yarn.

Note: these additional dependencies are required -- you may or may not have them on your system already:

• libudev
• libusb

These dependencies are installed on MacOSX by installing the XCode Developer Tools. For Linux, the example ubuntu installation command for additional deps is:

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. To do this, you will use Gananche, a tool that allows for the creation of local Ethereum test networks.

You should replace YOUR_NODE_URL with the URL of whatever Kovan or mainnet Ethereum node that you wish to use. Infura provides easy access to Ethereum and is one method that you could use to get your node URL.

Start ganache.

yarn ganache-fork YOUR_NODE_URL

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 --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 your deployment parameters

It is recommended to keep the default empParams struct and only customize your construction parameters by passing in the listed mandatory args. See the script or documentation for more details.
