💡 Inspiration

The inspiration behind ArSubscribe's on-chain transaction notification system was the growing need for individuals to stay informed and in control of their cryptocurrency activities within the decentralized finance (DeFi) ecosystem. As blockchain enthusiasts, we recognized the importance of real-time updates for wallet transactions in the ever-evolving world of cryptocurrencies.

What it does

ArSubscribe offers a seamless solution to keep users updated on their on-chain transactions. By subscribing to our notification system, users receive instant email alerts whenever any transaction involving their wallet address occurs on the blockchain. Our user-friendly landing page provides a clear and concise explanation of our protocol, illustrating why it's an indispensable tool for anyone engaged in blockchain and DeFi.

How we built it

The development of ArSubscribe's on-chain transaction notification system involved several key steps:

  • Subscription - Using Arweave as DB the user subscription data is stored as a wallet - email pair. It uses Arweave transactions with the support of tags to store the subscription data.
  • Email service - The service listens to the Arweave net via GraphQL queries for all the transactions happening pertaining to subscribed users, it pulls the transaction information including block details, and creates a notification email. The emails are sent using Arsubscribe753@gmail.com via nodemailer.
  • UI - The App offers an intuitive way to subscribe to the notifications. TO login into the app users can connect with their ArConnect wallet.

Challenges we ran into

One of the main challenges was to come up with a very light app (within 100Kb).

Accomplishments that we're proud of

We are proud to have our app deployed to the arweave.net and ready to use 🍾.

What we learned

The hackathon was a very fun experience with full of learnings.

What's next for ArSubscribe

Looking ahead, we have exciting plans for ArSubscribe:

  • Customizable Alerts: Enhancing the notification system to allow users to customize their alert preferences, including specific transaction types and thresholds.
  • Mobile App: We are exploring the development of a dedicated mobile app to provide users with even more convenient access to transaction alerts on the go.
  • Instant Alert: Currently alerts are fired when blocks are successfully mined, we want to add support for pending transactions as well.

ArSubscribe is all about helping out blockchain fans with up-to-the-minute info on their crypto moves. We're here to make sure you're always in the loop when it comes to the fast-paced universe of decentralized finance. Jump in now and keep up with all your crypto adventures
