Re: Bitcoin Taproot transaction STEP BY STEP on bitcoin-cli...

Use PSBT instead of raw transaction:

First import the necessary descriptor to the wallet (command already provided).
Secondly, create a transaction:

Code:

createpsbt "[{\"txid\":\"<TXID>\",\"vout\":<N>}]" "[{\"<address1>\":<amount1>},{\"<address2>\":<amount2>}]"

Thirdly, process the psbt (update, sign):

Code:

walletprocesspsbt "<PSBT from above command>"

Fourthly, finalize it:

Code:

finalizepsbt "<processed PSBT from above command>"

Lastly, send it to mempool:

Code:

sendrawtransaction "<signed raw transaction from above command>"
