I used to be quite stubborn, always saying "I only look at on-chain data," thinking that the data wouldn't lie to me.

As a result, when I opened multi-chain wallets, my assets were shattered: some gas on this chain, an NFT lying on that chain, another address locked with inexplicable LP tokens...
On-chain data is indeed real, but you can easily get overwhelmed by it yourself.

Now I have a simple approach: my main wallet only does two things—large transactions and cold storage;
each chain has a fixed "small change wallet" dedicated to paying gas and testing new protocols;
for blockchain games, I even open a separate isolated wallet, so I don't risk my main assets to inflation, studios, or price spirals.
Once a week, I do a reconciliation; if I find it too fragmented, I merge accounts, and if I need to cut losses, I do—no dragging it out.

Honestly, having more wallets doesn't make you safer; it just makes you more likely to forget, and in the end, you might rug yourself.
For now, this is enough—staying alive is the most important thing.
