so i have lost my wallet then @KukaiWallet

If you have lost your wallet and do not have the seed or the keystore file, then there is unfortunately no way to recover your wallet. It is important to keep your seed and keystore file safe and secure, as this is the only way to access your wallet and funds. It is also important to back up your wallet regularly to ensure that your funds are safe. You should also make sure to use strong passwords for any wallets you create, and to never share your seed or keystore file with anyone.

When you accessed the seed based wallet using Kukai you were asked to provide a password to encrypt and download a “keystore” file that contains your private key (whether you imported the seed from elsewhere or you created it new in Kukai does not matter). If you don’t have the seed then look for that file and if you remember the password for it then you can import that keystore, the default name for the file is hd-wallet.tez
