In this method, users create a transaction and sign it with their private key.
The signed transaction is then sent to the blockchain network for validation and execution. This ensures that only the owner of the private key can perform the transaction.
Advantages:
A high level of security is required when signing with a private key.
More control over payment funds, as customers manage them directly.
Disadvantages:
Transactions sent to the blockchain network will incur additional transaction fees.
More complex integration requires an understanding of transaction signing and validation processes.
