a view very concrete examples relevant to a project like yours:
- With EEZ: Anyone with funds on Ethereum can e.g. buy/bake “bread” with a single tx from Ethereum. This tx could directly trigger things on Gnosis (like buying/staking/ bread)
So generally you will no longer need a dedicated wallet with xDAI on Gnosis - anything than can be done on Gnosis can directly be done from any mainnet wallet.
The same if true for the other direction: Anything that can be done on Ethereum can be done from a Gnosis account. So, e.g. you can hold Bread on Gnosis and with a single tx swap this into another asset on Ethereum and send this asset (lets say USDC to e.g. any CEX or offramp service that accepts USDC on Ethereum)
More examples: you can read any price oracle on Ethereum directly from Gnosis. You can use protocols (e.g. register a name) on ENS or .wei again, directly from a Gnosis wallet.
