Taproot Multisig There are three wallets used to create a wallet. All work is based on this https://github.com/bitcoin/Bitcoin/blob/master/doc/multisig-tutorial.md. Here are the external and internal xpubs of each.

Wallet 1 (External + internal xpub)

Wallet 2 (External + internal xpub)

Wallet 3 (External + internal xpub)

Here is my description.

external_desc="tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh"

For the first debate tr Use and use the internal xpub of wallet 1. sortedmulti_a Use the outside to configure 2-3. I call getdescriptorinfo command:

 ./build/src/bitcoin-cli -signet getdescriptorinfo $external_desc

  "descriptor": "tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh",
  "checksum": "546p4cqh",
  "isrange": true,
  "issolvable": true,
  "hasprivatekeys": false

And I used the description to import the descriptor JSON to the wallet. This is what I used to make JSON.

external_desc_sum=$(./build/src/bitcoin-cli -signet getdescriptorinfo $external_desc | jq '.descriptor')
multisig_ext_desc="(\"desc\": $external_desc_sum, \"timestamp\": \"now\")"

After that, I call importdescriptors New empty wallet method:

./build/src/bitcoin-cli -signet -named createwallet wallet_name="multi_tr" disable_private_keys=true blank=true
./build/src/bitcoin-cli -signet -rpcwallet="multi_tr" importdescriptors "$multisig_ext_desc"
./build/src/bitcoin-cli -signet -rpcwallet="multi_tr" getwalletinfo

The response of the importer is as follows:

  "name": "multi_tr"

(
  
    "success": true,
    "warnings": (
      "Range not given, using default keypool range"
    )
  
)

The output of GET wallet information is as follows.

  "walletname": "multi_tr",
  "walletversion": 169900,
  "format": "sqlite",
  "balance": 0.00000000,
  "unconfirmed_balance": 0.00000000,

    "height": 234655
  

After seeing this output, I was excited and I wanted to create a new address for funding the Multisig wallet, but an error occurred.

./build/src/bitcoin-cli  -signet -rpcwallet="multi_tr" getnewaddress
error code: -4
error message:
Error: This wallet has no available keys

After finding an alternative, I found it deriveaddresses The method for the use of the use worked and I was able to search for some addresses.

./build/src/bitcoin-cli  -signet deriveaddresses "tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh" "(0,2)"

)

My question is as follows:

• The first method is why generatenewaddress Doesn’t it work?
• no see deriveaddresses How to be recommended for general use? If so, I think we need to store the used range to create a new address every time (because the same range creates the same address). Therefore, if you use (0,0) range, you must use (1,1) and so on.

thank you
