xDAI dApp Development Workflow?

#1

How would I go about testing and deploying a dApp for the the xDAI sidechain? Is there a preferred version of solidity? Do web3 and ethersjs still work? Just getting started and looking for help understanding the process.

You deploy the app the same way you deploy on Mainnet. You have to use different native token (xDai) and RPC endpoint.
