Welcome to Web3alert

Web3alert is a service for creating and receiving Web3 notifications.

It turns blockchain/runtime events, external data, and user-defined conditions into clear alerts that can be delivered to Telegram, Discord, Slack, webhooks, and other channels.

What you can do

As a user, you can:

• subscribe to ready-made marketplace integrations;
• create subscriptions for your workspace;
• keep addresses, resources, and data sources in one working context;
• receive alerts for selected events, addresses, contracts, runtime calls, or custom conditions.

As a project or integration owner, you can:

• create a project;
• describe triggers that read data from blockchain or timer sources;
• add providers, filters, transforms, and defaults;
• build templates and topics so other users can subscribe more easily;
• import triggers from ABI, Substrate metadata, or other supported descriptions.

Core idea

Web3alert is built around a small set of entities.

Projects describe integrations. A project can be a blockchain network, protocol, contract, community project, or a set of custom events.

Triggers describe which source items to read, how to filter them, how to enrich them, and what output to produce.

Templates turn triggers into understandable subscription scenarios for users.

Subscriptions connect a selected trigger/template with a workspace, inputs, filters, resources, and delivery settings.

Resources manage delivery channels and related external connections.

Data sources describe data origins: blockchain endpoints, runtime metadata, and custom source runtimes.

Addresses help store and reuse addresses in subscriptions and filters.

Where to start

If you want to use ready-made alerts, start with Subscriptions and Create subscription.

If you want to create your own integration, start with Projects, Triggers, and Templates.
