User Password Protected (UPP)

User Creates Password for Protection
The encrypted private key can only be decrypted by the user-created password/passphrase. This two-factor security design is based on the Bitcoin BIP38 open-source standard.

First, create a passphrase
Use open-source software tool to auto-generate a BIP38 intermediate code based on that passphrase
Then send the intermediate code to us
A BIP38 confirmation code is engraved on each wallet
You can verify that the encrypted private key can actually be decrypted by your passphrase
