Get a bitcoin address on MainNet #7824

Closed Arctrix closed 2 years ago

Arctrix commented 2 years ago

Hello,

I have some bitcoin on Pionex exchange. I'd like to send it to my electrum wallet. All the bitcoin addresses I own start with "bc1". Pionex refuses to send to addresses starting with "bc", displaying that error : "Haven't supported the BTC lightning network. Please change to another address not beginning with bc."

I tried everything on my wallet, but I can't find how to generate a MainNet address, starting with something else than "bc".

Here is the information from my wallet : Wallet type : standard Script type : p2wpkh Keystore type : bip32 Lightning : Enabled

Thanks for your help

"bc1.." addresses are mainnet bitcoin addresses. They have nothing to do with Lightning. These are native segwit addresses, introduced in 2017. Modern services and wallets should be able to send to them. You should complain to that exchange to implement support for "sending to bech32".

See https://bitcoinelectrum.com/frequently-asked-questions/#why-am-i-being-told-my-address-is-an-invalid-bitcoin-address

If the receive address you got from Electrum begins with “bc1” then you may find that some other wallets and exchanges have trouble sending money to it. These addresses use a new form of encoding called bech32 which results in lower transaction fees when spending bitcoin but support for sending coins to them is not yet universal.

The solution to this problem is to run electrum with the --nosegwit command line switch and create a new Electrum wallet.

Once you’ve created a new wallet you can receive coins to it instead. You can also switch between wallets via file > open or file > recently open.

Thanks for your answer. I'll look into it, maybe I'll have to open a new wallet with CLI.
