Electrum Bitcoin Cash "Q" Addresses

[JollyGood]

So, I tested a desktop wallet and the receiving addresses start correctly with: "1" prefix

When I used the MPK to add to Ubuntu Digital Ocean all addresses on the server start incorrectly with: "Q" prefix

When I use testnet faucet I can receive BCH on "1" prefix addresses but when I use "Q" prefix addresses the transaction fails

Why is the Ubuntu server showing all addresses starting with "Q" when the same MPK desktop wallet shows all addresses starting with "1"?

It's not incorrect.
Addresses that start with "q" are Bech32 addresses, similar to bc1 addresses in bitcoin.
It was introduced to differentiate BCash addresses from legacy bitcoin addresses.
They're equivalent to legacy addresses that start with "1" as they have the same private keys.

When I use testnet faucet I can receive BCH on "1" prefix addresses but when I use "Q" prefix addresses the transaction fails

Bech32 addresses are a new address format and as such aren't backwards compatible.
Wallet software must be updated to support the new address type.

You can use an address translator, such as this to Convert from Bech32 to legacy format

Thank you for the reply. My desktop wallet is the latest Bitcoin Cash/Electron-Cash v3.2 and I also have v3.2 running on my Digital Ocean Ubuntu server. When I view addresses on the desktop I see "1" but on the server they are "Q".

Please advise which is the wallet that needs updating, the desktop one which already has "1" prefix or the Ubuntu server one which shows "Q" prefix? Since both are running v3.2 please advise how I am supposed to update the one that needs updating

3.2 is the latest version of electron cash.
It already supports cashaddr format.
Click the blue button on the bottom right corner of the screen near the settings icon as shown below


If the blue icon is on it will show receiving addresses in the Bech32 format; if it's off it will show addresses in the legacy base58 format.

@Xynerise thank you for the explanation, it makes sense now.

Would you know how run the desktop wallet in testnet mode?

For what wallet?
Electron cash or Bitcoin ABC?
Both should work the same way as their Bitcoin counterparts.

The windows wallet: https://electroncash.org/

I tried both downloads, ElectronCash-3.2.exe and Portable Version but neither allow running in testnet unlike Electrum which installs the testnet option in windows start menu. I can install Bitcoin Cash testnet on the remote Ubuntu server but cannot get it open or run in testnet on my windows desktop.

Since Electron cash is a fork of Electrum, the --testnet argument should work also.

Thank you, I got it working in testnet on Windows 10 using v3.2 I am running some tests to try to sync the balance of the desktop wallet to that of the Ubuntu server.

Thanks for your help
