-### Networks
+The Hardhat environment relies on the following environment variables. The `dotenv` package will attempt to read them from the `.env` and `.env.secret` files, if they are present.
 
-By default, Hardhat uses the Hardhat Network in-process.

+| `PKEY_TESTNET`     | private key for test/development use on `testnet` network     |
+| `PKEY_MAINNET`     | private key for production use on `mainnet` network           |
+| `REPORT_GAS`       | if `true`, a gas report will be generated after running tests |
 
-To use an external network via URL, set the `NODE_URL` environment variable and append commands with `--network generic`:
+### Networks
 
-```bash
-NODE_URL="[NODE_URL]" yarn run hardhat test --network generic

+By default, Hardhat uses the Hardhat Network in-process. Two additional networks, `mainnet` and `testnet` are available, and their behavior is determined by the configuration of environment variables.
