Deploying a blockchain application with two backend and frontend directories can seem like a daunting task, but with platforms like Netlify, the process can be simplified. In this article, we will guide you through the steps to deploy a blockchain application with two directories using Netlify.

Firstly, it's important to ensure that the Application Binary Interface (ABI) of the smart contract is included in the public part of your application. This will allow the user interface to communicate with the smart contract. To do this, you can place the ABI file in the public folder of your frontend.

Next, you need to specify the environment variables in Netlify for your application. This will enable Netlify to recognize the sensitive information that your application needs to function properly. You can add these variables by accessing the "Environment" tab in your Netlify site settings.

In the Build settings of Netlify, you need to specify the runtime, base directory, build command, and publish directory. For a Next.js application, you should specify the runtime as Next.js and the base directory as "front". For the build command, you can use "yarn build" or "npm run build".
Finally, the publish directory should be set to "front/.next".

Once you have configured all the deployment options, you can push your application to Netlify using your preferred method (such as Git or the command-line interface). Netlify will automatically handle the building and deployment of your application.

In conclusion, deploying a blockchain application on Netlify can seem complicated, but it can be simplified by following the steps outlined above.
By ensuring that the ABI is included in the public part of your frontend and specifying the environment variables in Netlify, you can ensure the proper functioning of your application. Finally, by configuring the build options correctly, you can safely deploy your application on Netlify.
