[Feature] Sample env file in the Codebase

🚀 Feature Request: Add a .env.sample File

Description

Introduce a .env.sample file to the repository to standardize and simplify the setup process for managing environment variables.

Motivation

Managing environment variables without a clear template can be challenging, especially for new developers. The absence of a .env.sample file leads to confusion about:

• Which variables are required.
• The purpose of each variable.
• The expected format or example values.

Adding a .env.sample file will streamline onboarding and reduce errors caused by misconfigured or missing variables.

Proposed Solution

Create a .env.sample file in the root of the repository with the following:

• Placeholders for all required environment variables.
• Comments explaining the purpose of each variable.
• Example values (if applicable).

Example

# Required API key for authentication
API_KEY=your_api_key_here

# RPC endpoint URL
RPC_URL=https://your.rpc.url

# Private key for signing transactions
PRIVATE_KEY=your_private_key

Inizia ispezionando il repository alla ricerca di riferimenti a variabili d’ambiente e di istruzioni di configurazione esistenti. Crea il file .env.sample nella root con segnaposto, commenti e valori di esempio per le variabili richieste identificate. Il lavoro è completato quando il file documenta le variabili necessarie per la configurazione senza esporre credenziali reali.
