Lately I've been messing around with multi-chain wallets again, and when assets are scattered, it feels like the room has been overturned by a cat: some in Chain A, some in L2, and a bunch of leftover Gas coins that haven't been spent. My simple method is to divide them into "frequently used" and "long-term" categories; for frequently used, I keep two or three chains plus a main wallet, and the rest are stored in cold wallets or separate addresses, with clear notes explaining "why it's here," otherwise I forget in a couple of weeks. Watching everyone discuss whether they'll migrate before and after a major public chain upgrade, I'm actually more worried about a bunch of residual authorization and cross-chain bridge records in the wallet... To put it plainly, don't pursue full coverage; first, control the paths you can explain clearly, and you'll cut down half of the chaos.
