Just now, to earn some testnet points, I checked three blockchains and five wallets.

Halfway through, I forgot which chain I was on.
UX really can wear people out...
As for asset fragmentation, honestly, it's not that you're forgetful, it's that the tools force you to act like an accountant.

My current rough method: mainly use one wallet as a "cash account," and the others are just one-time accounts;
leave only a little gas on each chain, and transfer the rest that can be bridged back to the main chain/main protocol—don't scatter tokens everywhere.
Also, give addresses nicknames + simple notes (what this address is for, what permissions it has),
otherwise in a couple of weeks you'll be left with the haunting question, "Is this my address?"

And about the recent speculation on whether the mainnet will issue tokens,
the more people chase points, the more they should hold back:
first, think through the worst-case scenario = nothing at all + a bunch of permissions granted.
If the protocol hides risks and doesn't disclose them clearly, I’ll just block it outright,
to avoid cursing myself later.
