Snapchain:Solana Smart Contracts

Snapchain is a full-stack Web3 platform combining a no-code smart contract builder with a Next.js frontend for Solana blockchain applications. Create and deploy production-ready dApps without writing Rust code.

🌟 Snapchain Features

• Visual Contract Builder: Drag-and-drop interface for Solana programs
• Cross-Chain Ready: Built-in support for Polkadot and NEAR ecosystems
• One-Click Deployment: Direct to Solana devnet/mainnet from UI
• Wallet SDK: Integrated Phantom, Solflare, and Ledger support
• Template Contracts: Marketplace, NFT, DAO, and DeFi starters

⚡ Getting Started

Prerequisites

• Node.js 18+ & npm 9+
• Solana CLI (brew install solana-cli)
• Phantom Wallet (Browser Extension)

Installation

1. Clone the Snapchain repository:

git clone https://github.com/https://github.com/adityajha2005/snapchain.git

cd snapchain

2. Install dependencies:

npm install

3. Configure environment:

cp .env.example .env.local

Add your credentials:

NEXT_PUBLIC_SOLANA_CLUSTER=devnet
NEXT_PUBLIC_SNAPCHAIN_API_KEY=your_api_key_here

🛠️ Snapchain Workflow

1. Build Contracts Visually

   • Drag blockchain components (Tokens, NFTs, Governance)
   • Export as Solana Program (Anchor-compatible)

2. Deploy Contracts

# Using Snapchain CLI
snapchain deploy ./contracts/my_dapp.json --network devnet

# Or via dashboard interface

3. Integrate with Frontend

// src/config/snapchain.ts
export const SNAPCHAIN_CONTRACTS = {
  NFT_MARKETPLACE: process.env.NEXT_PUBLIC_NFT_CONTRACT!,
  TOKEN_FACTORY: process.env.NEXT_PUBLIC_TOKEN_CONTRACT!,
};

🖥️ Frontend Integration

Connect Wallet

import { useSnapchain } from "@snapchain/react";

const { connectWallet, connectedAddress } = useSnapchain();

return (
  <button onClick={connectWallet}>
    {connectedAddress ? truncateAddress(connectedAddress) : "Connect"}
  </button>
);

Execute Contract Method

const { execute } = useSnapchainContract("TOKEN_MINT");

const handleMint = async () => {
  const result = await execute("mintTo", {
    recipient: connectedAddress,
    amount: 100,
  });

  if (result.success) {
    toast.success("Tokens minted!");
  }
};

📈 Deploy to Production

1. Build production bundle:

npm build

2. Deploy to mainnet:

snapchain deploy --network mainnet-beta

3. Host frontend:

npm run dev
