TriMail is an all-around web3 AI-based solution for newsletters and article reading. Unlike conventional newsletter services, TriMail utilizes a combination of AI and blockchain technologies to create a flawless and secure newsletter and interest environment.
The idea of TriMail, incorporating both blockchain and AI, fascinated us. Imagine being able to receive newsletters only on topics you are genuinely interested in, all while ensuring security and privacy through blockchain technology. TriMail makes this possible with the help of Particle, Polybase, Tensorflow, and a custom SMTP server using Nodemailer.
- Seamless, secure, and engaging UX.
- Users can easily select and update their interests at any time.
- Regular and automatic mailing system.
- Custom AI model for fetching research papers based on user interests.
- Safe and secure data management.
- User's soul-bound ledger enhances security and transparency.
- Multiple sign-in options, including Gmail, phone, email, and web3 wallet.
- Fresh and user-friendly UI.
We utilized various features of the Particle network, such as wallet authentication, signing payments, managing the User's Soul Bound Token, and creating a seamless and secure user experience. The built-in wallet provided by Particle significantly improved the overall user experience.
Polybase seamlessly integrated with our requirements, enabling us to manage users' personal information, interests, and more. Additionally, by leveraging the dynamic NFT service, we easily created the User's Soul Bound Token, which can be updated simply by modifying the data on its row. Polybase was the perfect choice for this project.
-
Integrating Polybase with the Particle network:
- Integrating Polybase with the Particle network posed a challenge. We had to create a custom hook and make API calls to establish the integration.
-
Custom SMTP server:
- Setting up a custom SMTP server for regular mailing was a new experience for us. We utilized cron jobs and integrated Nodemailer with SendGrid to overcome this challenge.
-
Flask server for AI response:
- Deploying the AI model was a challenging task due to its large size, making it impractical to deploy on free hosting platforms such as PythonAnywhere or Heroku.
- Frontend: NEXT.js, ethers, Material UI
- Backend: Polybase, Particle auth, Particle connect, Flask, Node.js, Tensorflow
