Plutus Application Backend (PAB) provides developers with a quick way to create decentralized financial applications. Plutus will make it easy to focus on the frontend and business logic of your application. By taking care of the backend infrastructure, Plutus frees up developers’ time to focus on application development. This is possible thanks to the features of Plutus Core which provide the building blocks for decentralized applications.

Plutus, a platform that provides a native smart contract language as well as the infrastructure and tools required to implement smart contracts on Cardano, was launched with the Alonzo protocol upgrade. The Plutus platform enables developers to create decentralized apps (DApps) that interact with distributed ledgers via scripting capabilities.

In order for the ADALend protocol to function properly, PAB smart contracts and libraries are necessary. It serves as the cornerstone of an ecosystem that will allow for the development of a trustless financing environment. With its strong adaptability, PAB is well suited to different lending protocols and projects with similar characteristics. It is intended to provide this capability while still maintaining a high level of security and scalability throughout the platform. As a result, ADALend intends to construct their smart contracts with an emphasis on security, maintainability, and modularity, while also having the ability to dynamically load and unload functionality depending on the business’s requirements.

Plutus Application Backend (PAB) presents discoverable interfaces to external clients, like a mobile application and a website. PAB is also responsible for the security and user authorization of the financial data. It will be able to handle complex integration and business logic, which are required for the broader financial ecosystem.

PAB will track on-chain information for smart contract uses. While PAB will not be responsible for making decisions on lending, it will be responsible for the entire customer experience, from the time the customer enters their information and requests a loan, to the time the user is entitled to receive the tokens that have been lent to them. PAB will allow ADALend to be designed in a way that allows for a near-infinite number of lending services and users to interface with Plutus easily and securely.

The PAB is capable of switching fluidly between emulated and non-emulated (real network) operating environments. Unit tests, integration tests, property-based tests, and so on are made easier to create as a result of this improvement. Because the backend can receive and distribute messages, the PAB will enable the ADALend development team to interface with it with relative ease. As a result, the team can send standard requests to endpoints that have been exposed by the PAB and which correspond to actions and operations that any individual smart contract is capable of performing on its own.
