If you import a mnemonic and find that the generated wallet address is a new wallet address (inconsistent with the previously expected wallet address), there may be three cases that need to be checked one by one.
Case 1: The backup mnemonic is not the address of this wallet.
Because Dalong Wallet can manage multiple wallet addresses. Suppose you have two wallet addresses A and B. In the backup, the mnemonic of the A wallet is incorrectly assigned to the address of the B wallet, which will cause the import of the B wallet, but the import of the A wallet is a mnemonic, so The resulting address is the address of the A wallet, not the address of the B wallet that you want to import.
Tip: You can backup the mnemonic and back up its corresponding wallet address to avoid such problems.
Case 2: mnemonic transcript error
Another possibility is the mnemonic transcript error. If the transcript is wrong, there will be a small possibility to generate a new wallet address.
Case 3: Path setting problem
In addition, it is also possible that you have set the path, about the cognitive problem of the path, you can click here to view. Generally, when importing a wallet, the default path can be used. It is theoretically feasible to set the path by itself, but it will increase the difficulty of backing up the wallet.
