🔧 Installation & Deployment

Metalog uses dfx (Dfinity SDK), Node.js, and Vite for deployment.

1️⃣ Install Dependencies

# Install Dfinity SDK (dfx)
sh -ci "$(curl -fsSL https://internetcomputer.org/install.sh)"

# Check dfx version
dfx --version

# Clone repository & install dependencies
git clone https://github.com/recov-ai/ICP-Hackethon.git metalog

cd metalog

npm install

---

2️⃣ Configure Environment Variables

Ensure the .env file is set up in metalog_frontend/.env:

VITE_BACKEND_CANISTER_ID=<CANISTER_ID_METALOG_BACKEND>
VITE_FRONTEND_CANISTER_ID=<CANISTER_ID_METALOG_FRONTEND>
VITE_AUTH_PROVIDER=https://identity.ic0.app

🔹 Replace <CANISTER_ID_METALOG_BACKEND> and <CANISTER_ID_METALOG_FRONTEND> with the actual canister IDs after running dfx deploy.

---

3️⃣ Run on Local Network

dfx start --background

rm -rf .dfx node_modules .vite

dfx deploy --network local

npm run dev

🔗 Access the application:

• 👉 Frontend: http://localhost:5173/?canisterId=<CANISTER_ID_METALOG_FRONTEND>
• 👉 Backend Candid UI: http://127.0.0.1:4943/?canisterId=<CANISTER_ID_METALOG_BACKEND>

4️⃣ Deploy to ICP Mainnet

To deploy to the ICP main network:

dfx deploy --network ic

🔹 Once complete, use the new canister ID for the .env before restarting the application.

💡 ICP Integration in Metalog

Metalog uses Internet Computer Protocol (ICP) to support application security, privacy, and scalability. Here are some key aspects of ICP integration in Metalog:

✅ 1. Identity & Authentication

• Users log in via Internet Identity (II) at identity.ic0.app.

• Each user is assigned a Principal ID, ensuring decentralized and secure authentication without email or passwords.

✅ 2. Smart Contract (Canister) for Backend

• metalog_backend acts as a smart contract (canister) on the ICP blockchain.

• Stores all user data, transactions, and logic in the backend canister.

• No centralized servers, all data is managed within ICP's blockchain ecosystem.

✅ 3. Security & Decentralization

• No centralized database → User data is stored in decentralized canisters.

• Enhanced privacy → Only users have full control over their data.

• No third-party access → No company can access or control user data.

• Uses ICP Stable Memory to ensure persistent and secure data storage.

✅ 4. ICP Token Payments

• Consultation sessions are paid using ICP Tokens, directly integrated into Metalog.

• ICP Wallets are supported for seamless transactions.

• No credit cards required, transactions are executed via ICP’s blockchain, ensuring transparency and speed.
