View All on GitHubAI Summary: Develop a NestJS-based dispute resolution system that integrates with smart contracts. This involves automating dispute detection, implementing a multi-tier arbitration system (automated and human), managing evidence (using IPFS), incorporating voting, enforcing timelines, handling appeals, and executing resolutions via smart contracts. A reputation system for arbitrators is also required. Thorough testing is crucial.
AI Summary: Build a robust transaction processing engine in NestJS using the saga pattern. This includes implementing atomic transactions, distributed transaction handling, automatic retries, rollback capabilities, transaction status tracking and logging, smart contract integration, queue management, and idempotency handling. Thorough testing is required to validate atomicity, saga pattern implementation, rollback, retries, and performance under load.
AI Summary: Develop a NestJS service to monitor blockchain events in real-time. This involves creating event listeners, processing pipelines, data storage, robust error handling (retries, dead-letter queue, circuit breaker), and handling blockchain reorganizations. Thorough testing is required to ensure reliability, accuracy, and scalability.
AI Summary: Implement a comprehensive audit trail and compliance system in NestJS, including logging all operations, ensuring immutability with cryptographic verification, meeting regulatory (AML/KYC, GDPR) requirements, providing reporting and export capabilities, managing data retention, and offering search and filtering functionalities. This involves creating a dedicated module with interceptors, designing database entities, implementing compliance algorithms, and thorough testing.
AI Summary: Develop a comprehensive user management system in NestJS, including registration, profile management (with KYC/AML verification, preferences, and picture uploads), activity tracking, account suspension/recovery, search/filtering, and privacy settings. This requires creating a UserModule with CRUD operations, user entities, file upload and KYC integration services, DTOs, validation, and logging, along with thorough testing.
AI Summary: Implement robust security middleware in a NestJS application, including input validation (class-validator), rate limiting (Redis), CORS configuration, Helmet.js integration, SQL injection/XSS protection, API key management, request/response sanitization, and security audit logging. Thorough testing is required to cover vulnerabilities, edge cases, and configurations.
AI Summary: Implement a robust authentication and authorization module for a NestJS application using JWT, Passport.js, and RBAC. This includes features like refresh tokens, multiple authentication strategies, role-based access control, password hashing, rate limiting, session management with Redis, email verification, password reset, and 2FA support. Thorough testing is required.
AI Summary: Develop a cryptographic services module in NestJS for an escrow platform. This involves implementing digital signatures, encryption/decryption, key management, hashing, and message signing for blockchain transactions. The module should include robust testing, security considerations, and potentially hardware security module integration.
AI Summary: Implement a multi-channel notification system in NestJS, supporting email, SMS, push notifications, and in-app messaging. This includes building a template engine, integrating with external providers (SendGrid, Twilio), using Bull queues for asynchronous processing, and a WebSocket gateway for real-time updates. The system must also handle user preferences, delivery status tracking, retries, and provide a notification history and audit trail.
AI Summary: Develop a real-time analytics and reporting service using NestJS. This involves creating an AnalyticsModule, implementing interceptors for data collection, designing data entities and aggregation logic, building a report generation service, and integrating with a time-series database. The service should track various metrics (transaction volume, user engagement, escrow success rate, disputes, revenue), generate custom dashboards, and export reports in multiple formats (PDF, CSV, Excel). Thorough testing is required to ensure accuracy, performance, and functionality.
AI Summary: Develop a NestJS-based escrow management module with features including escrow creation, multi-milestone support, automated fund release based on defined conditions, status tracking, smart contract integration, real-time notifications, audit trails, and bulk operation support. Thorough testing across the escrow lifecycle, state transitions, smart contract integration, and performance is required.
