What is a JEFF wallet?
A JEFF wallet is essential for managing your JEFF tokens.

Essentially, the wallet enables you to handle your JEFF tokens, offering functionalities such as sending, receiving, and overseeing your cryptocurrency holdings.
How does a JEFF wallet work?
JEFF wallets employ a dual key system to manage blockchain interactions effectively — a public key for receiving JEFF and a private key for secure transaction authentication.
