Backend — NestJS
NestJS was selected for the backend due to its robust architecture, which leverages TypeScript and supports modular development. This allows for highly maintainable and scalable code. NestJS also provides built-in support for GraphQL and WebSockets, essential for real-time data handling and API management — which is crucial for the project’s dynamic nature. Its strong typing and dependency injection features ensure the codebase remains clean and manageable, facilitating seamless integration with on-chain technologies and ensuring secure and efficient handling of blockchain interactions.Frontend — React + Next.js
React was chosen for the frontend due to its component-based architecture, which promotes reusability and maintainability. React’s virtual DOM ensures high performance by minimizing direct DOM manipulation, resulting in faster user interface updates. Its extensive ecosystem and strong community support provide access to a wide range of libraries and tools, enabling rapid development and iteration. React’s declarative nature simplifies the development process, allowing us to create a dynamic and responsive user experience aligned with the goal of delivering an intuitive and engaging platform. Next.js powers the custom shopfront for SEO-friendliness and server-side rendering of storefront pages.Data layer
MongoDB
Primary application database — cost-efficient, reliable, and well-suited to the dynamic
schema of products, listings, and orders.
Amazon S3
Object storage for product images, banners, exports, and other binary assets.
Cloud infrastructure (AWS)
Droplinked runs on AWS using the services that map naturally to its commerce + AI workloads.| Service | Used for |
|---|---|
| ECS | Containerized service orchestration (backend, 3rdp, services) |
| ECR | Image registry for the service containers |
| CloudFront | CDN for storefronts and static assets |
| S3 | Object storage |
| EC2 | Long-running compute |
| ELB | Load balancing |
| SageMaker | ML model training and hosting |
| Bedrock | Managed foundation models (image, text, NSFW classification) |
| Lambda | Event-driven serverless workloads |
Lending logic and mechanics
Droplinked combines on-chain inventory records with attested payment-history data for loan origination. This is the foundation of the dual-token framework — Lend DROPS (DLND) for senior secured exposure to real-world trade finance, with Yield DROPS (DYLD) as junior risk-buffer capital.Origination
Combining on-chain inventory records with attested payment history data — borrowers are
underwriten using verifiable network activity rather than only off-chain bank statements.
Competitive logic flow
Compared to traditional origination lending, the on-chain flow compresses the parties
involved and the steps needed to move from application to funded principal.
Automated commercial filings
The framework supports automated commercial filings based on geography and jurisdiction
for liabilities — so the legal wrapper around each loan pool stays in sync with the
on-chain state.
