Nexus Explorer

Problem Statement

Nexus Explorer is a comprehensive blockchain explorer platform that provides realtime monitoring and exploration capabilities for the Nexus ecosystem.The platform combines advanced transaction monitoring with seamless crosschain capabilities to create a unified experience for tracking and analyzing transactions across multiple blockchain networks.The platform enables users to explore intent based transactions across the Nexus ecosystem. Users can browse intents with advanced filtering, search by Intent ID or signature addresses, and view comprehensive transaction details including sources, destinations, signatures, and execution history.The platform also features an integrated monitoring system that continuously tracks intent status changes, transaction fills, and deposits across both Cosmos and EVM chains, ensuring real time data synchronization and comprehensive transaction visibility.The real time monitoring infrastructure tracks intents and transactions across Cosmos and EVM chains Avail Nexus SDK for crosschain transfers and unified balance management.

Solution

I combined TypeScript, PostgreSQL, and realtime monitoring infrastructure to create a comprehensive blockchain explorer experience.The architecture is split into the following components:Next.js Frontend: React based interface for exploring intents, viewing transaction details, and managing crosschain transfersRealtime Monitoring System: Continuously tracks intent status changes, transaction fills, and deposits across both Cosmos and EVM chainsCrosschain Infrastructure (via Avail Nexus SDK): Enables unified asset management across multiple chains with automatic routingThe monitoring system includes:Intent Monitor: Tracks intent lifecycle from creation to fulfillment, monitors status changes, and syncs data across multiple networksTransaction Syncer: Continuously monitors Cosmos and EVM chains for fill and deposit transactions, ensuring real-time data synchronizationDatabase Layer: PostgreSQL with connection pooling for efficient storage and retrieval of intent data, transaction history, and user activityThe frontend stack includes:Next.js 15 + TypeScript: For type-safe development with React Server Components for optimal performancePostgreSQL: For robust data storage with connection pooling and efficient queryingAvail Nexus SDK: For crosschain asset bridging, unified balance management, and transaction simulationTailwind CSS: For responsive mobile-first UI optimized for blockchain data visualizationReact Query: For efficient data fetching and caching of blockchain dataNexus Explorer transforms complex blockchain data into accessible, real-time insights for developers and users navigating the Arcana ecosystem.
