How offline signatures work

How can I use offline signatures to protect my assets?

Key generationThe user generates a pair of public and private keys on a computer without an internet connection. The private key is used to sign transactions, while the public key can be shared with others for address verification.

Create TransactionThe user creates unsigned transaction information in an offline environment.

Transaction SignatureThe user signs the transaction with their private key, generating the signed transaction information.
