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.

• Tatum's Chiliz Faucet for Testnet.

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

1. 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:

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 \
