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.

Dencun upgrade with EIP4844 is likely later this year, which will bring lower cost Layer 2 transactions. Follow the readiness of EIP4844: https://github.com/ethereum/pm/blob/master/Breakout-Room/4844-readiness-checklist.md Prague + E starname upgrade is probably 2024, possibly focused on EOF, then followed by a Verkle tree focused upgrade, but none of this has been decided.

The live date for the Shanghai upgrade is likely to be April 12, occurring at epoch number 620,9536. This was announced during the All Core Developers Execution Layer #157 call on 16 March 2023.

On December 8, 2022, the Ethereum core team held an All Core Developers (ACD) meeting. The Ethereum team agreed to target March 2023 as the release date for Shanghai’s mainnet launch. However, this is a tentative date based on the assumption that the Zhejiang, Sepolia, and Goerli testnets are successful.

Shanghai is the next major upgrade for the Ethereum network, following the Merge in September 2022. Key highlights of what to expect include:
