Can I settle channel states on a different chain than the one where the channel was created?

I want the user to be able to:
create a channel on Chain A -> Create an app session & use the application -> Submit the state on chain B and collect this assets (assuming chain B has liquidity)

Is it possible to do with the current clearnode implementation?
If not, can I implement this without breaking the architecture of erc7824 / nitrolite?

Yes, I suppose, the resize functionality can help, but in order to withdraw on chain B the user should open a channel there first.

[gabrielantonyxaviour]

yes, exactly. The user needs a channel on chain B, but what if we could combine the channel creation and withdrawl on Chain B in the same transaction.

for ex, I could create a channel on Chain A. use the application, have multiple signed states and finally commit them on chain B with would create the channel and get the funds for me.

The user cannot perform an attack my claiming on multiple chains because the signed app state clearly mentions on which chain the user can withdraw the funds from.

Still this flow needs to be battle tested for more edge cases, cause we are providing liquidity on chain B for the user funds to avoid cross chain bridging (Assuming we handle it in our infra side)
