Launch Contracts

This repo contains the smart contracts making up PrimeDAO.

Repository is organized as follows:

/contracts/test/- contracts used for tests.
/contracts/seed/- Prime Launch seed module contracts.
/contracts/utils/- utility contracts.

Development

requires

node >= 12.0

to install node modules

npm i

to compile run

npm run compile

to test

npm run test

to run coverage

npm run coverage

Environment setup

please prepare .env file

touch .env

and add the following

INFURA_KEY = infura key
MNEMONIC = mnemonic (choose our development mnemonic to be able to interact with the deployed contracts with the deployer address)
PK = private-key
ETHERSCAN_API_KEY = etherscan key

Note:.env should be created in root directory.

Deployment

This project uses the hardhat-deploy plugin to deploy contracts. When a contract has been deployed, it is saved as JSON to the deployments directory, including its address as well as its abi.

Since this is a project that is continuously being extended, it is generally not desirable to always deploy all contracts. Therefore, this project makes use of deployment tags. These are specified at the end of each deploy script. This makes it possible to deploy specific versions for a given contract as they are being developed.

There are two npm scripts that facilitate the deployment to mainnet and rinkeby. Both require the specification of tags. When using these scripts, at the end of the deployment, it automatically exports the addresses & artifacts in one file per network. These files can be found in the exports directory and, for example, can be used for dApp development.

If multiple contracts share the same ABI (e.g. multiple instances of an ERC20 token) this should be specified in deploy/sharedAbiConfig.js. If not yet available, you should manually add the shared ABI (e.g. the ERC20 ABI) to exports/sharedAbis.json. As a result, the deployment information is exported, the exports for contracts that share the same ABI will point to this shared ABI. This keeps file exports slim, which is beneficial for dApp performance. If this is still unclear, you could for example take a look at exports/rinkeby.json and look at the ABIs of the Dai and Weth contracts.

Deployment to rinkeby

General (one tag): npm run deploy:contracts:rinkeby --tags=<YOUR_TAG_NAME>

General (multiple tags): npm run deploy:contracts:rinkeby --tags=<YOUR_TAG_NAME1>,<YOUR_TAG_NAME2>

Example (deploys Migration contracts): npm run deploy:contracts:rinkeby --tags=Migration

Deployment to mainnet

General (one tag): npm run deploy:contracts:mainnet --tags=<YOUR_TAG_NAME>

General (multiple tags): npm run deploy:contracts:mainnet --tags=<YOUR_TAG_NAME1>,<YOUR_TAG_NAME2>

Example (deploys SeedV2 and Migration contracts): npm run deploy:contracts:mainnet --tags=SeedV2,Migration

Interacting with contracts

This project uses hardhat tasks to interact with deployed contracts. The associated scripts can be found in the tasks directory. To get an overview of all existing tasks you can run npx hardhat on your command line.

To get more information on specific tasks (e.g. what they do, which parameters they require etc.) you can run npx hardhat help <task_name>.

Here's an example of a command to execute a task on rinkeby: npx hardhat --network rinkeby changeOwner --address <0xsome_address>

Verify Contracts

to verify contracts, the enviornment variable should contain ETHERSCAN_API_KEY set.

npx hardhat verify --network mainnet <0xsome_contract_address>

single constructor argument can be passed as follows: npx hardhat verify --network mainnet <0xsome_contract_address> "Constructor argument 1"

multiple constructor arguments can be passed as follows: npx hardhat verify --network rinkeby 0xa1C2eab7286dB99F481682e8165d2F1F61C4D7Ad "PrimeDAO Rating Reputation" "PRR"
