Before testing, you need to adjust the variables NETWORK_ID and MY_CONTRACT_ADDRESS in js/blockchain_stuff.js. NETWORK_ID is the unique identifier of the chain you are using. In this example, I'm using 534351, which represents the Scroll Sepolia Testnet. If you wish to use another chain, I recommend finding the identifier on chainlist. Also, place the address of the CircomCustomLogic contract you just deployed into the MY_CONTRACT_ADDRESS variable.

Head to coinmarketcap Search for donut You'll see contract, copy the one from gnosis network Head to your metamask and add gnosis network using this Switch to gnosis after adding it to your metamask Click on add token and paste the donut contract then add it

I don't care if my transaction is leaked as long as my secret phrases are safe. Is it possible to leak your SP through a RPC? For example, there are many RPCs on https://chainlist.org/ And they have a security score for each one. Should I be worried about a low score?

With this said, chainlist.org is a commonly referenced site too. Just sharing what is in the documentation for MM :) .

3: You now need to add the Optimism network into Metamask. Go to chainlist.org, "connect wallet" (connect with Metamask), search for Optimism, click add to Metamask, approve, switch network. You'll now be on optimism.
