If you created your Sui wallet addresses using a seed phrase, you can recover them by opening the wallet, clicking the address bar on the top right, and selecting 'Add'.

If you're using Suiscanner and noticing familiar activity from addresses you used to control, but only one is now showing in your Sluch Wallet, it’s likely that the missing addresses were part of the same original wallet but created as additional accounts derived from your seed phrase. Most wallets like Sluch, Sui Wallet by Mysten, or Ethos use HD wallets, meaning multiple addresses can be generated from the same recovery phrase using different derivation paths. If you're only seeing one address now, your current wallet setup might just be loading the first default account.

To recover those missing addresses, open your Sluch Wallet and look for an option to add or restore additional accounts. This usually means clicking something like “Add Account,” “Recover Account,” or even “Import using mnemonic.” Once you enter your original seed phrase, the wallet should generate the full set of addresses tied to it, and the ones you saw on Suiscanner will reappear. Just make sure you're entering the exact same recovery phrase you used before—any change in words or order will generate a different wallet entirely.

If you're unsure which wallet originally managed those addresses, you can also try importing the same seed phrase into another wallet that supports Sui, like Sui Wallet by Mysten, Surf, or Ethos, and check if the addresses appear there under different accounts.
