Nexus Explorer

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.

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 transfers
• Realtime Monitoring System: Continuously tracks intent status changes, transaction fills, and deposits across both Cosmos and EVM chains
• Crosschain Infrastructure (via Avail Nexus SDK): Enables unified asset management across multiple chains with automatic routing

The monitoring system includes:

• Intent Monitor: Tracks intent lifecycle from creation to fulfillment, monitors status changes, and syncs data across multiple networks
• Transaction Syncer: Continuously monitors Cosmos and EVM chains for fill and deposit transactions, ensuring real-time data synchronization
• Database Layer: PostgreSQL with connection pooling for efficient storage and retrieval of intent data, transaction history, and user activity

The frontend stack includes:

• Next.js 15 + TypeScript: For type-safe development with React Server Components for optimal performance
• PostgreSQL: For robust data storage with connection pooling and efficient querying
• Avail Nexus SDK: For crosschain asset bridging, unified balance management, and transaction simulation
• Tailwind CSS: For responsive mobile-first UI optimized for blockchain data visualization
• React Query: For efficient data fetching and caching of blockchain data

Nexus Explorer transforms complex blockchain data into accessible, real-time insights for developers and users navigating the Arcana ecosystem.
