Public Minting

Ever needed some ERC20 tokens to test things with, but tired of looking for faucets?

Well, how about some tokens that you can just mint by yourself? That's what this is all about.

There are examples for regular ERC20 tokens (based on OpenZeppelin's contract), and Superfluid Pure Supertokens.

Etherscan verification

To try out Etherscan verification, you first need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Ropsten.

In this project, copy the .env.example file to a file named .env, and then edit it to fill in the details. Enter your Etherscan API key, your Ropsten node URL (eg from Alchemy), and the private key of the account which will send the deployment transaction. With a valid .env file in place, first deploy your contract:

hardhat run --network ropsten scripts/deploy.js

Then, copy the deployment address and paste it in to replace DEPLOYED_CONTRACT_ADDRESS in this command:

npx hardhat verify --contract contracts/StableToken.sol:StableToken --network mumbai 0xf3978Cd0b517910D55af7bA7d1278C55BcFB4a1A
