At their core, relay applications function as intermediaries that relay information between two or more parties. These applications ensure that data flows smoothly from one system to another, even when these systems may not be directly compatible or cannot communicate with each other on their own. Relay applications can be found in various sectors, such as telecommunications, IoT (Internet of Things), messaging platforms, and even blockchain technology.

    For example, in telecommunications, relay applications allow different network protocols to communicate with each other, enabling users across various networks to interact without technical difficulties. In messaging platforms, these applications ensure that messages are relayed from one device to another, maintaining the integrity and timeliness of the communication. Similarly, in the realm of IoT, relay systems help devices with different communication standards work together efficiently.
