How Can I cross bridge between Ethereum and Layer 2 Network?

[VicManton]

I have been on the look for a very cheap and fast way to do some cross-bridging between Ethereum and Layer 2 networks without using risky third-party bridges?

I would suggest the gateways or bridges from Optimism or Arbitrum, they are supported, well-known and provide secure ways to do what you need.

Probably zklink.. one of the feature is native asset aggregation. To fully understand it read this.

Your only choice is using the native bridge. However, it may be costly because you must pay all the fees to do your transaction. The only best way to use third-party bridges. It's too costly for me to paid 20 bucks just for a transaction.

I have often bridged my funds. I have tried native bridges from Optimism, Arbitrum, and even Blast.

The only way for you to remove the third-party bridge is to use the L2 developer's own bridge. I don't even see another possible solution for this.
