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.
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.

- Event Detection & Structuring - Events are automatically parsed, decoded, and structured
- Flexible Subscriptions - Define subscriptions based on addresses, contracts, event types, or custom criteria
- Instant Delivery - Matching events are instantly pushed via webhooks with sub-second latency
