Notifications

Numia Notifications

Numia Notifications provides a real-time, developer-friendly subscription system for tracking blockchain events across any network. Built for L1 blockchains and protocols, our notification infrastructure eliminates the need for custom indexing solutions, allowing your ecosystem to deliver responsive, event-driven experiences.

The Challenge​

In today's fast-paced, multi-chain environment, on-chain actions happen every second: transfers, swaps, NFT mints, liquidations, staking events, governance votes, and more. Most development teams spend significant resources building and maintaining infrastructure just to monitor these events—running indexers and listeners simply to power basic alerts or user activity triggers.

This infrastructure burden slows down development, increases operational costs, and diverts engineering resources from core product innovation.

The Solution​

Numia Notifications eliminates this friction by providing a production-ready, real-time event monitoring system that works across any blockchain. We handle the complex infrastructure so your developers can focus on building exceptional user experiences.

How It Works​

1. Continuous Indexing​

Numia continuously indexes on-chain activity across your blockchain network, capturing every transaction, smart contract call, and state change in real-time.

2. Event Detection & Structuring​

Events are automatically parsed, decoded, and structured through our real-time API layer, transforming raw blockchain data into clean, actionable event payloads.

3. Flexible Subscriptions​

Developers define subscriptions based on:

  • Specific wallet addresses
  • Smart contract addresses
  • Event types and methods
  • Custom filtering criteria

4. Instant Delivery​

Matching events are instantly pushed to your backend via webhooks, delivering structured JSON payloads with sub-second latency.

Key Features​

Event-Based Subscriptions​

Monitor any standard or custom on-chain event across your blockchain:

  • Token transfers and swaps
  • NFT mints, claims, and trades
  • Staking and delegation events
  • Governance proposals and votes
  • Liquidations and margin calls
  • Smart contract interactions
  • Custom protocol-specific events

Filter by wallet address, contract address, event type, or custom parameters to receive only the notifications you need.

Push-Style Webhooks​

Real-time, structured JSON payloads delivered directly to your backend endpoints:

  • Sub-second latency from on-chain to delivery
  • Reliable delivery with automatic retries
  • Configurable rate limiting and batching
  • Webhook signature verification for security

Custom Notification Templates​

Pre-built templates for common blockchain use cases:

  • Wallet activity monitoring
  • Staking and unstaking events
  • Governance participation tracking
  • NFT marketplace activity
  • DeFi protocol interactions
  • Liquidation alerts
  • Bridge and cross-chain events

Customize any template or create entirely new notification patterns for your specific needs.

Multi-Chain Support​

Monitor events across multiple blockchain networks simultaneously with a single integration. Numia Notifications is designed to be chain-agnostic, supporting any blockchain network.

Scalable Architecture​

Handle thousands of concurrent subscriptions across multiple chains without performance degradation. Our infrastructure scales with your needs, from small pilot projects to ecosystem-wide deployments.
