The more you use multi-chain wallets, the more they feel like drawers that get more cluttered the more you stuff them; not a lot of money, but a bunch of addresses... I currently mainly have two sets: one "hot wallet for frequent use" that only holds small amounts for interactions, and another "cold one" as a storage warehouse, which I try not to move unless necessary. Keep only a little gas on each chain, don’t try to allocate everything at once—anyway, I’ll keep moving things around later.

Recently, that bunch of testnet incentives and reward expectations have made people itchy, and the easiest way to fragment assets into chaos: crossing chains once here, claiming rewards once there, and eventually forgetting which address did what. My simple method is: after each interaction, I casually note in a memo "chain + last four digits of address + what I did," and at the end of the month, I consolidate unused small coins back to the main chain/main address. Focus less on the balance, more on whether I’m actually using it. I don’t know if the mainnet will issue tokens or not, but I’ll get my accounts in order first.
