Lately, I've been messing around with multi-chain wallets, and asset fragmentation really drives me crazy: some assets are on chain A, some on chain B, and there are dust balances from a few testnets... just looking at it is annoying. My simple method is to keep only one "main wallet" as a storage, and treat other chain wallets like pockets; use them and then consolidate. Once a week, I set a fixed day to count everything, and move the static assets to the same chain/same address, so I don't have to look for change every day.

Recently, modularization and the DA layer are being talked about enthusiastically; developers are probably thrilled, but users (like me) are just confused: the more chains there are, the more fragmented the wallets become. Honestly, management doesn't rely on memory but on rules: before transferring, clearly write down "why am I doing this on this chain," if you can't answer, then don't transfer. Just start with that.
