MYRIADFLOW CONTRACTS

Smart Contracts for MyriadFlow

You'll find here the NFT contracts, tests for that contract, a script that deploys those contracts. It also comes with a variety of other tools, preconfigured to work with the project code.

Installation

1. Clone the repo by using

git clone https://github.com/MyriadFlow/smartcontracts

1. Install the dependencies by using the command yarn. This way your environment will be reproducible, and you will avoid future version conflicts.

Configuration

1. Rename the file .env.example to .env
2. Update the values of the given parameters:

ETHERSCAN_API_KEY=
POLYGONSCAN_API_KEY=
ROPSTEN_URL=
RINKEBY_RPC_URL=
MATICMUM_RPC_URL=
ETHEREUM_RPC_URL=
MNEMONIC=

1. ETHERSCAN_API_KEY is required to verify the contract deployed on the blockchain network. Since we're using the Polygon Testnet, We need to get the API key from https://polygonscan.com

2. Next we need to update the RPC URL based on the network of our choice. Since we have chosen the Polygon Testnet, we need to provide MATICMUM_RPC_URL from the https://alchemy.com or https://infura.io. In case if we choose, Rinkeby or Ropsten, we need to update their respective RPC URLs.

3. Lastly we need to provide the wallet from which the gas will be deducted in order to deploy the smart contract. We provide the MNEMONIC i.e., The seed words from the ETH wallet/metamask to pay for the transaction. Ensure that there are enough funds in the wallet to pay for the transaction.

Compiling Contracts

Next, if you take a look at contracts/, you should be able to find StoreFront.sol & Marketplace.sol and the Rarible Royalties Library.

Compile the smart contract by using

yarn hardhat compile

or

yarn compile

Testing Contracts

This project has tests that uses @openzeppelin/test-helpers. If we take a look at test/, you should be able to find various test.js.

To run the tests, we can use command:

yarn test
&&
yarn coverage

Deploying Contracts

Next, to deploy the contract we will use a Hardhat script. Inside scripts/ we use launch.js and run it with suitable network, you like

yarn launch --network maticmum

API documentation

see documentation here

Etherscan Verification

To try out Etherscan verification, we need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Polygon Testnet - maticmum. Then, copy the deployment address and paste it in to replace DEPLOYED_CONTRACT_ADDRESS in this command:

yarn hardhat verify --network maticmum --constructor-args MarketplaceArguments.js DEPLOYED_CONTRACT_ADDRESS
yarn hardhat verify --network maticmum --constructor-args StoreFrontArguments.js DEPLOYED_CONTRACT_ADDRESS

where MarketplaceArguments.js & StoreFrontArguments.js is a javascript module that exports the argument list.

Marketplace Contract

StoreFront Contract

Finally, visit the contract address on the Blockchain Explorer (PolygonScan) and interact with the smart contract at section Read Contract and Write Contract
