...So if that real so its a very good decision.
The problem with high commissions in the Ethereum network cannot be solved with the help of bridge. Using the bridge, you move your cryptocurrency to another alternative network with a lower commission, but when transferring, you will still need to pay a commission on both networks.
If they can lower the transfer fee, why not? But if not, why move it to unfamiliar network? ETH already earned their credibility as a network, this is why people are trusting this despite of high gas fee. But if they will move to another network which we have no idea about their foundation or if they will stay long in the market, they have no assurance if they can get the services they want. We can only assess their performance once they are already up and running. If they are still in the development stage, then, we can't talk about them yet.
