Once you've finished setting up MetaMask, you will need to select the appropriate network in order to interact with Zesty Market. Zesty currently functions on Rinkeby, which is one of the test networks, or testnets, available on Ethereum. No real money will be used on the testnet, which makes it a risk-free way of trying out the platform. Switching networks is as easy as going to the top drop-down and selecting Rinkeby Test Network. Once Zesty launches on Matic, this section will be updated with steps on how to switch to using Matic as well.
