Once this step is done: For future bridging, I recommend Orbiter.finance https://www.orbiter.finance/ (lower gas fees) to bridge to ZKSync.

In step 5 it says "Go to https://www.orbiter.finance/ and do the following: Select Arbitrum Nova as the network you're bridging from, Select Arbitrum One for the network you're bridging to."

Visit the Orbiter website and connect your MetaMask wallet to the site. Initiate the bridging process, allowing you to move your Ethereum from Arbitrum One to Arbitrum Nova. Follow the prompts and wait for the confirmation.

Seeing your other comments you converted BTC to ETH then sent said ETH to your wallet on the zkSync network, if that's what you did, it simply the same address as your eth wallet, if you want to take your ETH out of the zksync network, you can use https://www.orbiter.finance/ from there you can select zksync Era as the source network and then send it to the network of your choice, the destination address is the same as the one the original funds come from.

I used https://www.orbiter.finance as a bridge.

https://www.orbiter.finance, layerswap just a few I found. Let me know if you need more..

The bridges I use to go from ETH mainnet to Polygon (and vice versa) are umbria and orbiter fiance. Never had any issues with these and a lot of people here use them because they are usually pretty fast and have relatively low fees, but as a disclaimer I just want to add always use anything you're connecting your wallet to at your own risk. And don't take any help offered to you in the DMs as they will be scammers. Good luck!

You can always use the official bridges, but I love using Orbiter.finance for bridging, it's one of the cheapest options and works basically instantly.

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

You can check out a list of EVM chains here: https://chainlist.org/

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.

https://chainlist.org add chains with 1 click pretty much

You can also add the network you want to test in advance. How to add these test networks quickly? First, you can open https://chainlist.org/, check “Include Testnets”, search for the corresponding test network, and add it directly to your wallet.

Infura provides what's called an RPC endpoint. RPC is the way you expose a node to people who want to talk to it from a web browser etc. You can run your own node, using a normal computer, but it needs a big SSD drive (around 2TB) which costs a couple of hundred dollars. If you want to use a node hosted by somebody else, there are lots of other companies providing them. A good one is Alchemy. You can see a long list of publicly available RPC nodes for Ethereum (and also similar lists for other chains) at https://chainlist.org/
