# Communication

An important point to make the service run smoothly was to make fault-resilient communication between each entity in our protocol. 

From smart contract to platform, or from platform to backend service, we took time to create a robust inter-related communication protocol. 

Each stage of a loan request is handled by multiple levels of checkups to avoid the loss of any assets and the closing of each loan. Therefore, communication acknowledgements were placed between each entity. \
\
These entities are the SmartContract, The Bi-level Web3 API we’ve created, The Front-end platform, the back-end services and the Database.
