Dagger — The road ahead!

1 min read

We are very happy to announce that we have now added Ropsten testnet support for Dagger! (already available on Mainnet and Kovan)

Dagger provides a way for your DApps and backend applications to get Ethereum blockchain events, like transactions, receipts and logs in realtime. Dagger’s push notifications are far better than polling for events via web3 and is a significantly advanced way of listening to events.

We maintain hosted infrastructure for reliable and scalable realtime events, so that you do not need to worry about this part. Matic is committed to provide this hosted service for use by production-grade applications. As of now, we do not charge for the Dagger hosted service.Please do not hesitate to get in touch with us on Telegram, if you have any queries.

Here are some examples of what you can track with Dagger on Ethereum:

  • Get real-time transaction notifications in your web or mobile app
  • Track movement of tokens from and to specific addresses
  • Listen to multi-signature wallet events
  • Get updates on order filling, debt repayments, etc. on Dharma debt contracts
  • Monitor trades on Decentralized exchange contracts such as 0x and others
  • Listen to any event on an Ethereum contract

In fact, we are so pumped about the immense potential of data in the Ethereum and broader blockchain ecosystem, we have started working on a stealth project code-named Hermione, which we are building with our friends in the open source community (more details to come soon!). Hermione will be a scalable data processing system, that can be used for a wide variety of use cases involving Ethereum data.

If you are new to Dagger, here’s where you can get started — https://github.com/maticnetwork/eth-dagger.js

var Dagger = require("eth-dagger");

// connect to Dagger ETH main network (network id: 1) over web socket
var dagger = new Dagger("wss://mainnet.dagger.matic.network"); // dagger server

// Use mqtt protocol for node (socket)
// var dagger = new Dagger('mqtts://mainnet.dagger.matic.network'); // dagger server

// get new block as soon as it gets created
dagger.on("latest:block", function(result) {
  console.log("New block created: ", result);
});
 
// get only block number (as it gets created)
dagger.on("latest:block.number", function(result) {
  console.log("Current block number: ", result);
});

Matic itself uses Dagger internally to run key components of the network. Also, there are various third-party applications that use Dagger to run their production applications.

Take Dagger for a spin, and share your feedback.
