Title: Can't import a bech32 address to an existing wallet
Post by: darkv0rt3x on September 18, 2022, 07:12:20 PM

Hi

I'm trying to import a bech32 address to my Bitcoin Core wallet and I can't make it happen.

These were the steps:

Code:

$ bitcoin-cli --named --rpcwallet=MyWatchWallet importaddress label="incoming-from-xxxxxxxx" address="bc1qxxxxxxxxxxxxxxxxxxx" rescan=true p2sh=false
error code: -4
error message:
This type of wallet does not support this command

This is the wallet info:

Code:

 bitcoin-cli --rpcwallet=MyWatchWallet getwalletinfo
{
  "walletname": "MyWatchWallet",
  "walletversion": 169900,
  "format": "sqlite",
  "balance": 0.00000000,
  "unconfirmed_balance": 0.00000000,
  "immature_balance": 0.00000000,
  "txcount": 0,
  "keypoolsize": 0,
  "keypoolsize_hd_internal": 0,
  "paytxfee": 0.00000000,
  "private_keys_enabled": false,
  "avoid_reuse": false,
  "scanning": false,
  "descriptors": true,
  "external_signer": false
}

I'm using

Code:

$ bitcoin-cli --version

You are getting that error because importaddress (and importprivkey) are not supported on descriptor wallets[1]. Try making a wallet without descriptors and try again.

Alternatively, you can use importdescriptors to a descriptor wallet.
If the address is from Bitcoin Core, use getaddressinfo to get the address' descriptor and import it to your watching only wallet.
If from other wallets, construct a descriptor based from the address' pubKey and script type.

e.g. (RegTest):
getaddressinfo bcrt1q45ylq9spcg0q5aqzjcfu9ndxqawj28trxylq85

Code:

"desc": "wpkh([057761c1/0'/0'/1019']02b11c7ade3d64dc2a7fbaf43af8a021cc23a834895d3c16fbb276961f40380467)#sdng4gmc",

Import to MyWatchWallet (prvKey disabled):

Code:

importdescriptors "[{ \"desc\": \"wpkh([057761c1/0'/0'/1019']02b11c7ade3d64dc2a7fbaf43af8a021cc23a834895d3c16fbb276961f40380467)#sdng4gmc\", \"timestamp\":0,\"label\": \"incoming-from-xxxxxxxx\"}]"

Import to MyWatchWallet (prvKey disabled):

Code:

importdescriptors "[{ \"desc\": \"wpkh([057761c1/0'/0'/1019']02b11c7ade3d64dc2a7fbaf43af8a021cc23a834895d3c16fbb276961f40380467)#sdng4gmc\", \"timestamp\":0,\"label\": \"incoming-from-xxxxxxxx\"}]"

I tried getaddressinfo in my online node. But the address in question is not from this node and I got no field named "desc": like in your case!
I tried with 2 wallets I have in this online node.

Code:

$ bitcoin-cli --rpcwallet=MyWatchWallet getwalletinfo
{
  "walletname": "MyWatchWallet",
  "walletversion": 169900,
  "format": "sqlite",
  "balance": 0.00000000,
  "unconfirmed_balance": 0.00000000,
  "immature_balance": 0.00000000,
  "txcount": 0,
  "keypoolsize": 0,
  "keypoolsize_hd_internal": 0,
  "paytxfee": 0.00000000,
  "private_keys_enabled": false,
  "avoid_reuse": false,
  "scanning": false,
  "descriptors": true,
  "external_signer": false
}

and:

Code:

$ bitcoin-cli --rpcwallet=p2tr-wallet getwalletinfo
{
  "walletname": "p2tr-wallet",
  "walletversion": 169900,
  "format": "sqlite",
  "balance": 0.00000000,
  "unconfirmed_balance": 0.00000000,
  "immature_balance": 0.00000000,
  "txcount": 0,
  "keypoolsize": 4000,
  "keypoolsize_hd_internal": 4000,
  "unlocked_until": 0,
  "paytxfee": 0.00000000,
  "private_keys_enabled": true,
  "avoid_reuse": false,
  "scanning": false,
  "descriptors": true,
  "external_signer": false
}

Both are descriptor wallets but no field named "desc"

Code:

$ bitcoin-cli --rpcwallet=MyWatchWallet getaddressinfo bc1qxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
{
  "address": "bc1qxxxxxxxxxxxxxxxxxxxxxxxx",
  "scriptPubKey": "0014xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "ismine": false,
  "solvable": false,
  "iswatchonly": false,
  "isscript": false,
  "iswitness": true,
  "witness_version": 0,
  "witness_program": "bbxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "ischange": false,
  "labels": [
  ]
}

and

Code:

$ bitcoin-cli --rpcwallet=p2tr-wallet getaddressinfo bc1qxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
{
  "address": "bc1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "scriptPubKey": "001xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "ismine": false,
  "solvable": false,
  "iswatchonly": false,
  "isscript": false,
  "iswitness": true,
  "witness_version": 0,
  "witness_program": "bbxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "ischange": false,
  "labels": [
  ]
}

So, I presume I need to do this in the same node as the one where the addresses were created?

Yes, getaddressinfo should be used to the node and wallet where the address belongs. Otherwise, it wont return with its descriptor.
Additionally even if it's not from a descriptor wallet, it will return with a desc.

Here's my test (RegTest):
[To see the wallet type] getwalletinfo -rpcwallet=miner_wallet getwalletinfo

Code:

{
  "walletname": "miner_wallet",
  "walletversion": 10500,
  "format": "bdb",
...
}

[Export an address' descriptor (no private key)] getwalletinfo -rpcwallet=miner_wallet getaddressinfo bcrt1q45ylq9spcg0q5aqzjcfu9ndxqawj28trxylq85

Code:

{
  "address": "bcrt1q45ylq9spcg0q5aqzjcfu9ndxqawj28trxylq85",
  "scriptPubKey": "0014ad09f01601c21e0a74029613c2cda6075d251d63",
  "ismine": true,
  "solvable": true,
  "desc": "wpkh([057761c1/0'/0'/1019']02b11c7ade3d64dc2a7fbaf43af8a021cc23a834895d3c16fbb276961f40380467)#sdng4gmc",
  "iswatchonly": false,
...
}

  "iswatchonly": false,
...
}

Ok, but my goal was to be able to import a bech32 address, created in an offline node, in a different online node, so that I didn't need to go to the offline node every time I need something from that address.
But I'll try that just to test it out on my own. Then, I'll paste here my results or if I was able to do it or not!

Yes, that's the goal.
You have to get the address' descriptor from the offline node just one time.

You can even make an HD watching-only wallet with this method (but through the parent descriptors instead).

Ohh, ok I see...
I'll try that as soon as I can and will post if I succeed or not! Thanks a lot!

Ok, so I just tried to import the descriptor and chose to scan the blockchain late 2018. How long will it take approximately? Too many hours?

Edited;
Well, the thing didn't work but for some other reaasons:

Code:

$ bitcoin-cli --rpcwallet=MyWatchWallet importdescriptors "[{\"desc\": \"wpkh([bbcm4cmclite4m8p957cm8347tyowa87rcyam8ao8a3w4cnwclgrhw4o4)#aaaabbbb\", \"timestamp\":1538352000, \"label\": \"imported-from-old-offline-node\"}]"
error: timeout on transient error: Could not connect to the server 127.0.0.1:8332 (error code 0 - "timeout reached")

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

Yep, the error is totally unrelated to the command used and it's pretty much self-explanatory.

For the rescan, it depends on your system's specs. Could be minutes to hours.

I got this error but I think the rescan is still going in the background, because yesterday, iirc, I tried to run the command again and I got that message saying the rescan was info in or something like that. The above error message makes no sense because everything is running. Both bitcoin node and LN node.

Ok, so I just checked and the address was imported. I assume this is now a watchonly address in this wallet, right?

Edited 1;
The imported address says it is "iswatchonly": false,, this means it has the PKs available?I thought this would be a WatchOnly address! Can anyone clarify this, please?

But the descriptor only contains the pubKey, as you can see in the getaddressinfo's result, it's the same as the pubKey.
Also, when you go to the send tab, you won't have any option to "Send" but only "Create Unsigned".

I wonder if showing that it's "iswatchonly": false, is a bug or intended.

It is intended insofar as descriptor wallets do not distinguish between watchonly and spendable internally as legacy wallets do. This distinguishing happens at the wallet level now rather than at a script level, so wallets are watchonly, not items contained within a wallet.

Thanks for the clarification.

@darkv0rt3x In addition to only having the public key, (based from the above) Creating a descriptor wallet with "Disable Private Key" option will make the wallet watching-only.
In my quick test, it wont accept a descriptor with privKey.
On the other hand, a descriptor wallet with private keys enabled wont accept the example descriptor in my test since it only has a pubKey.

Thank you both @achow101 and @nc50lc for clarifying. I think I can call this one solved.
