This is a really interesting aspect and has a lot of potential - such as having the ability to use cross-chain smart-contracts.

One of the much talked about obstacles for ETH going forward are rising Gas fees. 
That's just the current reality until ETH 2.0 reaches its final upgrades, there's not much anyone can do to avoid it. How do you see Gas fees playing a factor here?
Just as an example, using UniSwap atm users are sometimes paying $10 usd transaction fees (idk who much Gwei that comes to) is pretty steep for average users.

One thing that comes to mind is some wallets cover (expensive) transaction fees [ETH] or CPU [EOS] for their users - Anchor Wallet by @greymass does this or Bloks.io in the EOS ecosystem. 

Is this something that you envision could be added to Vessel down the line so average users don't get priced out by exorbitant fees?

Cheers, thanks in advance and I'll be voting for this proposal as I think it's an important step in the right direction.
