+# Hardhat 3 Project
+
+This is a Hardhat 3 project, which uses the native Node.js test runner (`node:test`) and the `viem` library for Ethereum interactions.
+
+
+
+## Building
+
+To build, run:
+
+```shell
+npx hardhat build
+```
+
+
+
+### Running Tests
+
+To run all the tests in the project, execute the following command:
+
+```shell
+npx hardhat test
+```
+
+You can also selectively run the `node:test` tests:
+
+```shell
+npx hardhat test nodejs
+```
+
+
+
+### Make a deployment to Next Testnet
+
+This project includes an example Ignition module to deploy a contract to our testnet.
+
+To run the deployment to Next Testnet, set your mnemonics in an .env file (MNEMONICS=...) and run:
+
+```shell
+npx hardhat ignition deploy --network next ignition/modules/PowersOfTwo.ts
+```
