## Connect to Mainnet and Testnet

Chiliz Chain is available through a Mainnet for your production projects, and has a Testnet for testing purposes. The Chiliz Testnet is called Spicy Testnet.

## Obtain testnet tokens

You can obtain free test CHZ tokens through a faucet, allowing you to experiment on Spicy Testnet without the financial risk of testing on Chiliz Mainnet.

There are currently two faucets available:

* [Spicy Faucet](https://spicy-faucet.chiliz.com/).
* [Tatum's Chiliz Faucet for Testnet](https://tatum.io/faucets/chiliz).

For more details on faucets, go to our dedicated page:

## Deploy and verify a contract

Building a smart contract is an essential part of the creative project that leads to a dApp for Chiliz Chain — or any blockchain, really.

There are two steps that you **must** go through once you have built your dApp's smart contract:

1. Deploying the contract on Chiliz Chain.

[deploy-a-smart-contract](https://docs.chiliz.com/develop/basics/deploy-a-smart-contract)
{% endcontent-ref %}

2. Verifying that contract.

## Run a Chiliz Chain Node

Running your own Chiliz Chain node provides control and privacy but demands more technical skill and resources.

This page gives you the essential parameters to launch your node:

```bash
docker run \
-v $(pwd)/my-datadir:/datadir \
--name ccv2-node \
-p 8545:8545 \
-p 8546:8546 \
chilizchain/ccv2-geth:latest \
--chiliz \ # for Chiliz Mainnet. Use --spicy for Spicy Testnet.
--datadir=/datadir \
--ipcdisable \
--http \
--http.addr=0.0.0.0 \
--http.api=eth,net,web3,debug,txpool \
--http.port=8545 \
--http.corsdomain="*" \
--http.vhosts="*" \
--ws \
--ws.addr=0.0.0.0 \
--ws.api=eth,net,web3,debug,txpool \
--ws.port=8546 \
--ws.origins="*" \
```
