EasyDAG: The Conversational BlockDAG Assistant

A submission for the BlockDAG Hackathon 2025. visit https://easydag-for-blockdag.onrender.com/ to access the deployed website

Overview

EasyDAG is a web application designed to make smart contract development on BlockDAG accessible to everyone. While blockchain technology can be complex for newcomers, our project significantly lowers this barrier with a dual-mode AI assistant. This allows both beginners and experts to generate, understand, and discuss smart contracts using natural language.

Key Highlights

Dual-Mode AI Assistance

The contract generator can be switched between two convenient modes:

• Conversational Mode: Chat with a friendly, knowledgeable AI powered by Google Gemini 1.5 Flash to ask questions about BlockDAG and smart contracts in plain English.
• Protocol Builder Mode: Generate secure, ready-to-use smart contract templates using a clean, form-based interface with no coding experience required.

Multi-Contract Support

Build three essential contract types out-of-the-box:

• ERC-20 Tokens
• Staking Protocols
• Vesting Contracts

Interactive Community

EasyDAG features a dynamic community forum where users can post questions, create blog entries, upvote or downvote posts, and collaborate with others.

Secure Wallet & Guest Authentication

The user-friendly interface includes auto-expanding chat inputs, hover-to-preview contract templates, and dynamic forms that adapt to your choices for a clean, responsive experience.
