To interact with a live or test network, you'll need:

1. An rpc URL
2. A Private Key
2. A wallet private Key
3. ETH & LINK token (either testnet or real)

Let's look at an example of setting these up using the Sepolia testnet.

You can get one for free from [Alchemy](https://www.alchemy.com/), [Infura](https://infura.io/), or [Moralis](https://moralis.io/speedy-nodes/). This is your connection to the blockchain.

2. Set your `PRIVATE_KEY` environment variable.
2. Set your `WALLET_PRIVATE_KEY` environment variable.

This is your private key from your wallet, ie [MetaMask](https://metamask.io/). This is needed for deploying contracts to public networks. You can optionally set your `MNEMONIC` environment variable instead with some changes to the `hardhat.config.js`.

For other networks like mainnet and polygon, you can use different environment variables for your RPC URL and your private key. See the `hardhat.config.js` to learn more.
