What I would love to see in a wallet:

Why are you going for 0x123..456@optimism.eth instead of eth:0x123.. which is already supported by some apps (most famously gnosis safe)?

Rio de Janeiro, State of Rio de Janeiro, Brazil

Sure but if we’re using ens, then you can put chain information directly as a text record or a subdomain like optimism.vitalik.eth or polygon.randomaardvark.coinbase.id

This got discussed a lot. The main goal is to move the chain registry to ENS so that launching L2s is permissionless and not dependent on a centralized repository.
