Need to move some ETH from Arbitrum back to Ethereum mainnet. What bridge services have you used that offer reasonable fees and fast transfers? Concerned about security since I've heard stories about bridge exploits. Any reliable recommendations?

Yes, you should use trusted bridge services that support multiple Layer 2 networks, including Arbitrum, Optimism, and Base. Before initiating a transfer, check the transaction fee, as it depends on network congestion. It is also worth comparing the fee structures on different platforms to avoid unnecessary costs. I recommend considering the Optimism bridge, as it works quickly https://defiway.com/bridges/bridge-eth- ... m-ethereum
