Blockvyn is an AI-Native Web3 engineering protocol that delivers a complete trust layer for autonomous agents and smart contract systems. We build infrastructure that lets builders ship AI agents on-chain with verifiable legitimacy — not just promises.

Stop shipping promises. Start shipping proof.

Frontend

• HTML5 + TailwindCSS (CDN)
• Vanilla JavaScript (no framework)
• Iconify (Solar + Simple Icons sets)
• UnicornStudio (animated background)

Backend

• PHP 8.0+ (compatible with any shared hosting)
• Native SMTP client (zero dependencies)
• Anthropic Claude API integration
• HMAC-SHA256 JWT-like tokens
• Session-based OTP storage

Auth

• Email OTP via SMTP (Hostinger / any provider)
• Phantom Wallet (Solana) integration
• LocalStorage-based session persistence

This is a static site with a PHP backend. To run locally:

# Clone the repo
git clone https://github.com/blockvyn/blockvyn.git
cd blockvyn

# Copy env template
cp .env.example .env
# Edit .env and fill in your credentials

# Start PHP dev server
php -S localhost:8000

# Visit http://localhost:8000

Create a .env file (use .env.example as a template):

# Email (SMTP)
SMTP_HOST=smtp.hostinger.com
SMTP_PORT=465
SMTP_USER=noreply@yourdomain.com
SMTP_PASSWORD=your_email_password
SMTP_FROM_EMAIL=noreply@yourdomain.com
SMTP_FROM_NAME=Blockvyn

# Auth secret (generate via: openssl rand -hex 32)
AUTH_SECRET=your_64_char_random_string

# Anthropic API (for AI Agent chat)
ANTHROPIC_API_KEY=sk-ant-xxxxxxxxxxxxx
ANTHROPIC_MODEL=claude-sonnet-4-6

# Rate limits
CHAT_MAX_MESSAGES_PER_HOUR=50
CHAT_MAX_TOKENS=2048

⚠️ Place .env 1 level ABOVE public_html/ on shared hosting. Set permissions to 600.

1. Upload static files to public_html/:

   • All .html files
   • logo.png, favicon.svg, banner.png
   • .htaccess
   • api/ folder (entire)

2. Place .env in the parent directory of public_html/

3. Create email account (e.g. noreply@yourdomain.com) in Hostinger panel

4. Enable SSL (free Let's Encrypt via Hostinger)

5. Test login at https://yourdomain.com/login.html

Any LAMP / LEMP stack works. Just ensure:

• PHP 8.0+ with curl extension
• .env placed outside webroot
• HTTPS enabled
• File permissions: chmod 600 .env

Claude reply → JSON response → render in chat UI

System prompt is dynamically constructed from each agent's configuration:

• Name, Role, Personality
• Target Chain (Ethereum, Solana, etc.)
• Selected Capabilities (Trading, Treasury, Governance, etc.)
• Custom operator instructions

Each agent becomes a unique Claude persona with its own scope and personality.

• 40% — Public Sale & Liquidity
• 20% — Ecosystem & Builder Grants
• 15% — Team & Advisors (vested)
• 15% — Treasury & DAO
• 10% — Strategic Partners

• Q2 2026 — Genesis: TGE, Agent Studio public launch, first 100 verified agents
• Q3 2026 — Trust Registry: On-chain verification, SDK release
• Q4 2026 — Multi-Chain: Solana, Arbitrum, Optimism, A2A messaging
• 2027 — Permissionless registration, auditor marketplace, full DAO
