Deploying Appchains on Avail using Mandara ( Incentivized Testnet)

I will be introducing a simple guide on recent avail Incentivized challenge on the Goldberg Testnet.

Previously, we have attempted few challenges on Avail Testnet. Here is another opportunity to earn more points in preparation of Avail Mainnet.

However, Listing and adding your Appchains to public dashboard isn’t available publicly. This is the best time to get started early as there might be limitations to number of Appchains deployers.

This Article won’t cover how to get started with VPS or Virtual Machines to get your Roll App running.
