Title: Checking for balances of address [range] using Bitcoin Core using descriptors Post by: NotATether on May 10, 2023, 05:43:32 AM I'm designing a wallet that is going to use a Bitcoin Core node to fetch balances of addresses. And yes I am storing master public keys using standard BIP44 derivation. So in other words: m/44'/0'/0'/0/[0-1000 or whatever] and m/44'/0'/0'/1/[0-1000 or whatever], for legacy addresses for example. Other types of addresses are constructed similarly.
But I cannot figure out how to fetch the balance of these xpubs as a descriptor. I would prefer the UTXOs be separated from each other and tagged with the address they belong to. Of course, if I was working with single addresses, I could just use importaddress, but legacy wallets are deprecated and will be removed soon. And for example, this fails with "Error -5 missing checksum": bitcoin-cli -rpcwallet=some_wallet importdescriptors '[{"desc": "addr(<address>)", "timestamp": "now"}]' I'm running Bitcoin Core 24.0.

Example (Regtest): Code: getdescriptorinfo "addr(bcrt1qjd5q9e4du3rj4f0gux9794tmf330rtaplqkel9)" Then, include it to your importdescriptors command. Example: Code: importdescriptors "[{\"desc\": \"addr(bcrt1qjd5q9e4du3rj4f0gux9794tmf330rtaplqkel9)#xtu8a9fg\",\"timestamp\": \"now\"}]"Title: Re: Checking for balances of address [range] using Bitcoin Core using descriptors Post by: NotATether on May 10, 2023, 08:50:38 AM I tried that, and it seemed to be rescanning the wallet (I used a real address with UTXOs after block height 690000) and then I got this:
Code: error: timeout on transient error: Could not connect to the server 127.0.0.1:8332 (error code 0 - "timeout reached") followed by this (when trying again) Code: error code: -4 Which RPC do I use to check the status of the rescan?

I can see the UTXOs for the address, but now I would like to scan for an xpub with a derivation path and specific range. How may I do that?

How may I do that? importdescriptors command's arguments are listed in here: https://developer.bitcoin.org/reference/rpc/importdescriptors.html (https://developer.bitcoin.org/reference/rpc/importdescriptors.html)descriptors are documented here: https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md (https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md) Here's an example extended public key with derivation path to 'external_index/address_index' ( /0/* ) and with 'range' argument. (commonly used path for deriving receiving addresses from an xpub): Code: importdescriptors "[{\"desc\": \"wpkh(tpubDC8SbfxbQot4BA2kg476RyWA5EM5yawYj9ZUMbAtDeBEBgPNVTyAYRKDCLJQcbUP1yBus4Z9BUMSZANmaNGruFYnfPXwXBDLrPyU8vM7QWy/0/*)#wg24ts7y\",\"timestamp\": \"now\",\"range\": [0,100]}]" |
