Function Lock is a security feature designed to restrict specific functionalities of a cryptocurrency wallet or related application. It ensures that certain critical actions, such as sending funds or making changes to settings, can only be performed under predefined conditions.This feature helps protect users from unauthorized access and potential theft. For instance, a wallet may implement a Function Lock that requires multi-factor authentication, such as a password or biometric verification, before allowing a withdrawal. In addition to security, Function Lock can serve as a safeguard for users who might accidentally initiate transactions. By locking certain functions, users are given a buffer against impulsive decisions that could lead to loss of funds. Overall, Function Lock enhances both security and user confidence by ensuring that important actions are closely monitored and controlled.
