# How to Code, Deploy, and Interact with a Polygon (MATIC) Smart Contract

Follow the full written tutorial [here](https://docs.alchemy.com/alchemy/tutorials/how-to-code-and-deploy-a-polygon-smart-contract).

Follow the full video tutorial here.

## Quickstart

1. `npm install`

2. Rename `.env-example` to `.env`, and populate the variable values.

    1. Grab `API_URL` from [www.alchemy.com](https://alchemy.com/?a=polygon-smart-contract) by setting up a Polygon Mumbai testnet app.

    2. For `PRIVATE_KEY`, use your Ethereum wallet address's corresponding private key.

    3. You can leave `CONTRACT_ADDRESS` blank until you deploy with `npx run scripts/sample-script.js`, then grab the address where you deployed your contract to.

    4. `ALCHEMY_API_KEY` is very similar to `API_URL` except you can remove the http or ws prefix.

    5. `MATIC_URL` you can grab from [www.alchemy.com](https://alchemy.com/?a=polygon-smart-contract) but make sure your Alchemy app is a Polygon Mainnet app.

3. run `npx run scripts/sample-script.js --network mumbai` to deploy your contract to Mumbai testnet

4. run `npx run scripts/greet.js --network mumbai` to modify blockchain state by calling the Greet function on your smart contract.

5. Repeat those steps with `--network matic` to deploy and interact on Polygon (MATIC) mainnet chain.
