arbitrum-token-bridge VS OB_ReturnCabin

I've just bridged some Eth from Mainnet to Arbitrum One via https://bridge.arbitrum.io/, and the transaction looked to have completed properly.

You can bridge it with the arbitrum bridge. https://bridge.arbitrum.io/

Try https://bridge.arbitrum.io/ to see if it supports bridging between those two.

I always use https://bridge.arbitrum.io/, but I heard there are others? But why would I use them, since they all do the same`? Isn't the native one the most secure?

This will take 7 days to process, and you'll have to manually claim your ETH from the bridge site https://bridge.arbitrum.io/

Anyone managed to bridge ETH from Arbitrum back to Mainnet using Trezor (through MM) on this page https://bridge.arbitrum.io ? I have been trying for several days now, not sure if the problem is on my end or Trezor doesn't want to play nice?

Unfortunately no. I use the Arbitrum Bridge (https://bridge.arbitrum.io/) to move assets from ethereum to arbitrum. Alternatively, some DEXes such as SushiSwap (sushi.com) allow cross chain transfers, though if you're trying to do arbitrum nova for moons specifically that's supported in fewer places and the bridge is your best bet.

Getting some ETH into your vault to pay for gas fees. You can either buy some from an exchange that supports Arbitrum Nova, or use the Arbitrum bridge to move over some ETH you already have.

i tried the official bridge I guess ( bridge.arbitrum.io ) but it does not allow nova - one. I'll try orbiter finance.

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.
