Deploy Pegasys V2 Script

This package includes a CLI script for deploying the latest Pegasys V2 smart contracts to any EVM (Ethereum Virtual Machine) compatible network.

Usage

This package vends a CLI for executing a deployment script that results in a full deployment of Pegasys Protocol v2. Get the arguments for running the latest version of the script via npx @pollum-io/v2-deploy --help.

As of v0.0.1 the arguments are:

> npx @pollum-io/v2-deploy --help
Usage: npx @pollum-io/v2-deploy [options]

Options:
  -pk, --private-key <string>               Private key used to deploy all contracts
  -j, --json-rpc <url>                      JSON RPC URL where the program should be deployed
  -w9, --weth9-address <address>            Address of the WETH9 contract on this chain
  -ncl, --native-currency-label <string>    Native currency label, e.g. ETH
  -o, --owner-address <address>             Contract address that will own the deployed artifacts after the script runs
  -s, --state <path>                        Path to the JSON file containing the migrations state (optional) (default: "./state.json")
  -v1, --v1-core-factory-address <address>  The V2 core factory address used in the swap router (optional)
  -g, --gas-price <number>                  The gas price to pay in GWEI for each transaction (optional)
  -c, --confirmations <number>              How many confirmations to wait for after each transaction (optional) (default: "2")
  -V, --version                             output the version number
  -h, --help                                display help for command

The script runs a set of migrations, each migration deploying a contract or executing a transaction. Migration state is saved in a JSON file at the supplied path (by default ./state.json).

To use the script, you must fund an address, and pass the private key of that address to the script so that it can construct and broadcast the deployment transactions.

The block explorer verification process (e.g. Etherscan) is specific to the network. For the existing deployments, we have used the @nomiclabs/hardhat-etherscan hardhat plugin in the individual repositories to verify the deployment addresses.

Note that in between deployment steps, the script waits for confirmations. By default, this is set to 2. If the network only mines blocks when the transactions is queued (e.g. a local testnet), you must set confirmations to 0.

Development

To run unit tests, run yarn test.

For testing the script, run yarn start.

To publish the script, first create a version: npm version <version identifier>, then publish via npm publish. Don't forget to push your tagged commit!

FAQs

How much gas should I expect to use for full completion?

We estimate 30M - 40M gas needed to run the full deploy script.

When I run the script, it says "Contract was already deployed..."

Delete state.json before a fresh deploy. state.json tracks which steps have already occurred. If there are any entries, the deploy script will attempt to pick up from the last step in state.json.

Where can I see all the addresses where each contract is deployed?

Check out state.json. It'll show you the final deployed addresses.

How long will the script take?

Depends on the confirmation times and gas parameter. The deploy script sends up to a total of 14 transactions.

Where should I ask questions or report issues?

You can file them in issues on this repo and we'll try our best to respond.
