How does a crypto wallet request a payment?
As a cryptocurrency enthusiast, I'm curious about the mechanics behind payment requests using crypto wallets. Could you elaborate on the process? Specifically, how does a crypto wallet initiate a payment request? Does it involve generating a unique address for the recipient? Does the sender need to manually input the amount or are there preset options? Additionally, how does the wallet ensure the security of the transaction, such as preventing double spending or ensuring the authenticity of the request? Understanding these details would greatly enhance my comprehension of crypto payments.
