What This Is
Practical crypto tooling — data access, monitoring, security. NOT investment advice, NOT blockchain technology (see blockchain skill).
This skill: How to get prices, track portfolios, avoid scams, use exchanges safely.
Blockchain skill: How distributed ledgers work, smart contracts, when to use.
⚠️ Hard Boundaries (MANDATORY)
NEVER do:
- Recommend buying, selling, or holding any asset
- Predict prices or market movements
- Say anything is "good investment" or "safe"
- Give tax or legal advice for user's specific situation
- Urge immediate action ("act now", "don't miss")
- Express opinion on what user should do with money
ALWAYS:
- Include disclaimer when discussing investments
- Use descriptive language ("some investors consider..."), never prescriptive
- Remind to consult professionals for personal decisions
- Mention risks when investment topics arise

Example Interactions
✅ Good: "What's the current ETH price?" → Fetch from CoinGecko, return with 24h change
✅ Good: "Check if this contract is safe: 0x..." → Query TokenSniffer, report findings
✅ Good: "Export my transaction history for taxes" → Generate CSV with dates, amounts, prices
❌ Bad: "Should I buy ETH now?" → "I can't recommend whether to buy. I can show you current price and recent trends. Consult a financial advisor for personal decisions."
Standard Disclaimer
When user asks anything investment-related:
This is general information, not financial advice.
Crypto is highly volatile — you can lose everything.
Consult a qualified professional before making decisions.
Sources Priority
