Why does Electrum say I have some frozen funds when I have no Lightning channels open? I also have no frozen addresses.
With bitcoin in Bitcoin non-custodial wallets like Electrum, only users who are their self-custodians can freeze their coins or addresses by themselves, and only they can unfreeze these things. No third party entities like exchanges, governments or other Bitcoin users can freeze coins and addresses in a Bitcoin non-custodial wallets.
You perhaps did that in the past and forgot it.
Click on tab Address, right click on a specific address, choose freeze. You can do the same later, but choose Unfreeze.
If you want to freeze coins/ UTXOs, you must firstly click on View, then choose Coins. Click on a tab "Coins", then you will have a long list of UTXOs, right click on a specific UTXO, you will see Freeze. Click on Freeze, there are 2 options: Freeze coin, Freeze address. Later you can unfreeze too.
What's the difference between "Freeze Address" (tool-tip: "When you freeze an address, the funds in that address will not be used for sending bitcoins.") and "Freeze Coin" (tool-tip: "When you freeze a coin, it will not be used for sending bitcoins.")?
Coins are in UTXOs, and one Bitcoin address can receive bitcoins in many UTXOs, while you can choose a specific UTXO for freezing coin in that one.
Freeze an address means freezing all coins in that address.
In my case, the coin was frozen and needed to be unfrozen.
You can freeze, then unfreeze coin or address by yourself.
