To restore a Cardano wallet using a recovery phrase:
- Open your Cardano wallet software (e.g., Daedalus, Yoroi).
- Choose the 'Restore Wallet' option.
- Select the type of wallet you're restoring (e.g., Shelley-era wallet).
- Enter your recovery phrase words in the correct order. Most Cardano wallets use 24 words, but some may use 15.
- Create a new spending password for the restored wallet.
- Wait for the wallet to sync with the blockchain and verify your balance.
- Once restored, immediately transfer funds to a new wallet if you suspect the recovery phrase might have been compromised.
Always keep your recovery phrase secret and stored securely offline.
