When you see a popup saying "The current network does not support this chain," you might instinctively want to click "Add Network" — but you are not sure if you should. Actually, you do not need to wo

You just deleted the connection session for a DApp in your wallet, and then you suddenly remember that a transaction still shows "pending." You may worry about whether its status will be affected. The

Your wallet pops up a request saying it needs you to authorize access to multiple chains—your first reaction might be "Why does it need so many chains? I'm not even using them," and then you click rej

You just got a new phone and opened a DApp—only to find the old session didn't connect and the page is still loading. This is normal. Old wallet connection sessions cannot be used on a new phone; you

When difficulty drops from its all-time high, your first reaction might be to worry that the network has become weaker. After all, if there is less hashrate, wouldn't it be cheaper to attack the netwo
