I'm testing segwit bech32 addresses and generated the following using bitcoinjs:

address: bc1qc7u5njf4nf2rj3zys642mfc7nct6kdven8j4e9

private key: 5Kkzs8XrJNAmf9VQDFeGBfaRvSByAvPK6DbDXw5BVqswWaXSG2Y

When I import this private key into electrum 3.0.5, it imports it as the following address: 1KD3SE71kGAcxw57BvcmUzsHwx3QxdPBW7

How do I go about sweeping funds from the bc1... address if electrum 3.0.5 sees the legacy format address instead?

Use Electrum 3.1.1 and prepend "p2wpkh:" to the private key before importing or sweeping it. For example:

p2wpkh:5Kkzs8XrJNAmf9VQDFeGBfaRvSByAvPK6DbDXw5BVqswWaXSG2Y

  • how do you output the segwit address just to make sure it matches that private key? – Patoshi パトシ Mar 24 '18 at 4:23

    bitcoin.address_from_private_key("p2wpkh:5Kkzs8XrJNAmf9VQDFeGBfaRvSByAvPK6DbDXw5BVqswWaXSG2Y") in the console tab of electrum (view menu> show console if you can't see that tab) – Abdussamad Mar 24 '18 at 4:28
  • thanks! I'm curious to how did you even figure this out to put "p2wpkh:" in front of the address? – Patoshi パトシ Mar 26 '18 at 16:19
  • @Patoshiパトシ It's in the release notes for 3.1: github.com/spesmilo/electrum/blob/master/RELEASE-NOTES#L72 – Abdussamad Mar 27 '18 at 14:38
