Data sources
Events, calls, blocks, transactions, and timers.
Marketplace + trigger builder
Web3 notifications, built as connected flows
Create notification projects from blockchain events, enrich them with external data, test the result, and let users subscribe to ready-made scenarios.
Triggers
Define the moment that should become a signal.
Enrichment
Add RPC, GraphQL, HTTP, Chain State, or Value history.
Transform
Shape raw data into clean output for rules and messages.
Templates
Package trigger logic into ready-made scenarios.
Subscriptions
Let users choose topics, filters, and delivery channels.
Explore notification projects
Find networks, protocols, and community projects with ready-made notification scenarios, or create a private workspace project before publishing.
Ethereum
evmcontracts
Contract events, transactions, and reusable app workflows.
Polkadot
substrateevents
Runtime events, governance activity, and account signals.
Polygon
evmscaling
Bridge, contract, and app activity alerts for Polygon projects.
Arbitrum
l2evm
L2 transaction, contract, and ecosystem notification flows.
How teams can use Web3alert
Web3alert separates technical trigger logic from the user-facing subscription experience. Builders keep control; users get simple scenarios.
Build a notification project
Create a public, private, or invite-only project for your protocol, dApp, community, or internal workflow.
Design smart triggers
Choose a blockchain source, add conditions, enrich the event, and shape the output users will receive.
Publish ready-made scenarios
Group triggers into templates so users can subscribe without understanding the underlying logic.
Deliver where people already are
Send alerts to Telegram, Discord, Slack, or webhooks from the same reusable flow.
From raw on-chain data to useful signals
Listen
Track blockchain activity or timer-based checks from project data sources.
Enrich
Bring in external and runtime data only when the source event is not enough.
Shape
Separate machine-readable output from clear human notification content.
Preview
Test a trigger before it becomes part of a project users can subscribe to.
Delivery channels
Webhook
WebhookComplex enough for builders, simple enough for subscribers
Marketplace-ready
Publish projects publicly, keep them private, or share access with a link.
Powerful without noise
Keep complex providers, transforms, and filters behind a simple subscription experience.
Built for teams
Use workspaces to manage projects for protocols, products, and communities.
