To make Remix IDE interact with the network through a Chainstack node:
Get MetaMask and set it to interact through a Chainstack node. See Interacting through MetaMask.
In Remix IDE, navigate to the Deploy tab. Select Injected Provider - MetaMask in Environment.
This will engage MetaMask and make Remix IDE interact with the network through a Chainstack node.
