### Deploying to Testnet

Watch this [5 minute Loom video ](https://www.loom.com/share/ddd9f2136e044fb5a241d9da281f31b8)describes the basics of getting setup on our Art Blocks contract.

{% hint style="info" %}

Infura: <https://www.infura.io/faucet/sepolia>

Bright Moments: <https://faucet.brightmoments.io/> (please post in your artist channel in the Discord, tagging [Henry](https://app.gitbook.com/u/nCoTKF1lYeX5JwzmZ6qAhqT2fsl2 "mention") with your wallet address to be added. 3 ETH p/hour)
{% endhint %}

1. Visit the staging home page: <https://artist-staging.artblocks.io/>.
2. Connect your wallet associated with the artist address you provided to the Bright Moments team and sign the nonce to connect to the Art Blocks staging website.
3. Visit your project’s test environment by going to the Sepolia URL, replacing the last field (PROJECT-ID) with your Project ID: [https://sepolia-artist-staging.artblocks.io/engine/fullyonchain/projects/](https://sepolia-artist-staging.artblocks.io/engine/fullyonchain/projects/0x6Ceab51Fc8EE931Df84d3db66E747b617EB7dE21/PROJECT-ID)[0x8651eFeBA58F94A3785113B6Bc60a50Aa305df4c/PROJECT-ID](https://sepolia-artist-staging.artblocks.io/engine/fullyonchain/projects/0x8651eFeBA58F94A3785113B6Bc60a50Aa305df4c/PROJECT-ID)
