I checked Swan's Address Derivation Library https://github.com/swan-bitcoin/xpub-tool.

I try to get m44 address, but I got m84. Why? Do you know is it any parameter to force return m44? I tried to pass path: "m/44'/0'/0'/0", but it did not help.

Do you have any idea?


export const addressFromXPub = (key) => {
      extPubKey: key,
      network: "mainnet",
      addressCount: 3,
    {path: "m/84'/0'/0'/0/0", address: "bc1qfgnqm6g46ys0h9gh606m76wemka2rrttrac90x"
    {path: "m/84'/0'/0'/0/1", address: "bc1qnvzdj2m4wsrcrtl30j5c304qa77v4h2s8ajp0r"
    {path: "m/84'/0'/0'/0/2", address: "bc1qjf5u77e6clwkxgf7a0shw7zq2nhqr4vjys7an0"
  • Where in your code are you trying to pass the derivation path as m/44'/0'/0'/0? I don't see it in your question. Also, xpubs already have the derivation path encoded in them. You can't change an xpub's deriv without changing the root and then create a new xpub/ypub/zpub. – m1xolyd1an Feb 27 at 3:46

The following key:


Corresponds to a level 3 public key w/index of 0x00000080 which is 0h/0'. In the context you've described it probably corresponds to "m/?/?/0'". This key's parent's fingerprint is 0x3ab9169c, so you'd need to provide the parent's full fingerprint to confirm the original derivation path.

Although m44 & m84 have the same master/root key, they have completely different level 1 keys, which would change all lower nodes. In short you can only derive m/... full paths from root keys, not child keys, which you've provided.

Edit: The key you've provided is probably meant for deriving receive & change addresses of a certain address type.

  • thanks, do you know here: iancoleman.io/bip39 which field contains the root keys? I tried both: Account Extended Public Key and BIP32 Extended Public Key to pass to addressesFromExtPubKey, but again m84 was returned, strange – János Feb 27 at 21:53
