Recover Cardano change addresses by scanning the internal HD role
A Shelley wallet restored with only its receiving-address branch can miss change. The role component of a CIP-1852 derivation path distinguishes external and internal addresses.
Scan the account’s two payment roles
The examples identify the same account and index seven. Role zero derives the external payment key. Role one derives the internal payment key commonly used for change. Use the wallet’s original derivation convention and address construction.

If a transaction sends change to the second path, extending only the external index range never discovers that key. Scan both roles with the wallet’s address discovery policy and check actual transactions or UTxOs on the correct network.
Keep staking and payment roles separate
The staking role serves a different credential and does not replace the two payment branches. Recovery also depends on the correct root-key generation scheme, passphrase and account index. A matching path string by itself cannot identify the original wallet. cips.cardano.org Cardano CIP-1852
