# Atria

Atria is Pulsy's off-chain backend for event-driven blockchain workflows. It turns on-chain events into real-time actions by running feeds that read blockchain data, apply custom logic, and deliver structured outputs.

## Quick Start

<Columns cols={2}>
  <Card title="Create, Test, and Deploy a Feed" href="/atria/dashboard/create-test-and-deploy-a-feed">
    Build a feed with AI or manually, test it against chain data, and start it.
  </Card>

  <Card title="Create an Output" href="/atria/dashboard/create-an-output">
    Set up a reusable connector with AI or manual configuration.
  </Card>
</Columns>

Use Atria when your team needs to monitor wallets, contracts, protocols, treasuries, bridge flows, DEX activity, lending risk, stablecoin movements, or other on-chain events without building the full ingestion and runtime layer yourself.

## What Atria Does

* Reads blockchain data from configured networks.
* Runs feed logic.
* Emits structured results only when your conditions match.
* Delivers matching results to outputs.
* Supports cloud, self-managed, private, and on-prem deployment models.

## The Core Idea

Atria is built around a [feed](/atria/core-concepts/what-is-a-feed). A feed is the primitive you use to build workflows: it selects a data source, runs event logic, optionally reshapes the payload, and triggers the next action through an output.
