 26 | ## Project Description
 27 | 
 28 | A dapp to mint your own text-based **Eternal Character NFT**.
 29 | 
 30 | **Eternal Characters** are the residents of **Eternal Domain world**. They consist of 3 main characteristics, Area of Control, Weapon and Rank.
 31 | 
 32 | **Area of Control -** Fire, Wind, Wave, Earth, Light, Shadow, Thunder, Space, Time, Gravity, Ice
 33 | **Weapon -** Sword, Spear, Shield, Hammer, Saber, Axe, Bow, Staff, Wand, Fist, Dagger, Scythe, Mace, Blade, Katana
 34 | **Rank -** Lord, King, Emperor, Venerable, Ancestor, Saint, God
 35 | 
 36 | ## Workflow
 37 | 
 38 | 1. Enter the dApp and connect the wallet to rinkeby network.
 39 | 2. Click on the Mint Character button.
 40 | 3. Metamask pops up and asks to confirm the transaction.
 41 | 4. After the transaction is successfully processed the user can see the minted character.
 42 | 5. The minted character is also added to My NFT page under Minted Characters section.

/frontend/README.md:
--------------------------------------------------------------------------------
 1 | This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
 2 | 
 3 | ## Getting Started
 4 | 
 5 | First, run the development server:
 6 | 
 7 | ```bash
 8 | npm run dev
 9 | # or
10 | yarn dev
11 | # or
12 | pnpm dev
13 | # or
14 | bun dev
15 | ```
16 | 
17 | Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
18 | 
19 | You can start editing the page by modifying `app/page.js`. The page auto-updates as you edit the file.
20 | 
21 | This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
22 | 
23 | ## Learn More
24 | 
25 | To learn more about Next.js, take a look at the following resources:
26 | 
27 | - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
28 | - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
29 | 
30 | You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
31 | 
32 | ## Deploy on Vercel
33 | 
34 | The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
35 | 
36 | Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
