Sweep Taproot and native Segwit v0 cash in a single transaction utilizing Bitcoin Core pockets

Commonly you’d use walletcreatefundedpsbt after which walletprocesspsbt. However since you have solely obtained two cash in your pockets that you simply need to sweep you may merely use sendall.

Let’s stroll by means of a copy of your state of affairs. I’ve created two regtest-WIF-encoded personal keys:

• cRZ9wuYhwKYm82rXfSk9hhc9beJy6p7rV4y3aoAdzqFD6YAUVQcJ (akin to 029d759b09cec94b6f2bd322cedd5d136e7f24a4936998fe24da09827d8a12e9dd)
• cVFkDn9fS1rwU1SR7geC3rgoGNXLpZXsnrCq2gutYVsGA2FoLpCD (akin to 03bd0d0b820dae844107803c9323fe73e81b9adf8abe329930ae9311dab6c3573e)

I am creating a brand new pockets and importing a tr() and wpkh() descriptor.

$ bitcoin-cli -regtest createwallet repro_stackexchange
{
  "identify": "repro_stackexchange",
  "warning": ""
}
$ bitcoin-cli -regtest -rpcwallet=repro_stackexchange importdescriptors '[{"desc":"tr(cRZ9wuYhwKYm82rXfSk9hhc9beJy6p7rV4y3aoAdzqFD6YAUVQcJ)#uj39yr2v","timestamp":"now"},{"desc":"wpkh(cVFkDn9fS1rwU1SR7geC3rgoGNXLpZXsnrCq2gutYVsGA2FoLpCD)#nayxphlw","timestamp":"now"}]'
[
  {
    "success": true
  },
  {
    "success": true
  }
]

Now i am sending a coin to every descriptor:

$ bitcoin-cli -named -regtest -rpcwallet=important sendtoaddress handle=bcrt1ps66a3wss3l0ay0agnkd57cfu6qrw26z632e0kez0ppjzkyaq0vhskxlrvs quantity=0.00042 fee_rate=1
b2e975dee4ab0c68748e85fc847d7ef3fef44f53ee95e4765b1cc2b2c33939d2
$ bitcoin-cli -named -regtest -rpcwallet=important sendtoaddress handle=bcrt1q9vsfxgf4t3wmtj9429g539txyv4p2qnuak03sv quantity=0.00043 fee_rate=1
e34a3b8116f328d2b1529134dfcc795fbe27eae3991eeb017bc582879cb73b81

We are able to see that the copy pockets obtained the 2 cash:

$ bitcoin-cli -regtest -rpcwallet=repro_stackexchange listunspent 0

  {
    "txid": "e34a3b8116f328d2b1529134dfcc795fbe27eae3991eeb017bc582879cb73b81",

  {

    ],
    "protected": false
  }
]

Now i am going to get the transactions confirmed and sweep the cash utilizing sendall:

$ bitcoin-cli -regtest -rpcwallet=important generatetoaddress 1 $(bitcoin-cli -regtest -rpcwallet=important getnewaddress)
$ bitcoin-cli -named -regtest -rpcwallet=repro_stackexchange sendall recipients="["bcrt1qre2fezscuke8qaj9ham2klddj2rt7m4s78tvqq"]" fee_rate=1
{
  "txid": "a39b70bf4636bb78053d10a3bc03eb6866e6777e84aeb274bb4002a543b7bb99",
  "full": true
}

Let’s examine the transaction. It does certainly spend the 2 cash from the pockets (one Taproot and one native segwit v0 as you may see from the witness):

$ bitcoin-cli -regtest getrawtransaction a39b70bf4636bb78053d10a3bc03eb6866e6777e84aeb274bb4002a543b7bb99 1
