[Enhancement]: cross chain address book

[marsrobertson]

Describe the enhancement

I'm aware I'm doxxing myself but my ENS names are on chain anyway, I'm not running darknet marketplace, I err on the side of adoption, simplicity, usability. Please don't hack me.

Steps to reproduce

1. Paste address that is in the address book on Ethereum - Binance deposit address
2. Change the chain
3. Paste the same address on Fantom - not found

Cross chain address book would be nice

• I have the same address cross chain
• My frens (anon dudes on the internet) have the same address
• Exchanges have the same address

I've tried to search for "address book" in open issues and didn't find, that's why opening a new issue.

Cross chain addresses do not always match. (See wintermute OP token exploit)

[marsrobertson]

Cross chain addresses do not always match.

Exception rather than a rule.

99% they match.

Balance of usability and security is towards unified address book.

Are there any genuine use cases where the same 0x123...ABC address belongs to different people?

In case of $OP and Wintermute:

It doesn’t necessarily work across chains. “Having control over mainnet Safe doesn’t guarantee control on other EVM compatible chains (unlike ordinary wallets),” Wintermute explained in a message to the Optimism community on the Layer 2’s forum.

I still believe it is an exception, not a rule. Since then, has any action been taken on the Gnosis Safe side to avoid similar exploits in the future?
