Crypto Skill

A skill for handling all cryptocurrency and blockchain-related tasks: research, analysis, market data, DeFi, NFTs, wallets, security, and Web3 education.

Core Capabilities

1. Price & Market Data

• Fetch real-time or recent prices via web search (CoinGecko, CoinMarketCap, Binance, etc.)
• Report market cap, 24h volume, circulating supply, all-time high/low
• Compare multiple tokens side by side
• Identify trending coins and movers

Workflow:

1. Search "[token] price coinmarketcap" or "[token] price coingecko"
2. Pull market stats and summarize clearly
3. Note data timestamp — crypto prices change fast

2. Token & Project Research

When asked to research a token or project:

1. Search for the official website, whitepaper, and recent news
2. Cover: what it does, tokenomics, team, roadmap, backers, risks
3. Check for audits (CertiK, Hacken, Trail of Bits)
4. Highlight red flags: anonymous team, no audit, inflated supply, unclear utility
5. Never recommend buying — present facts and let the user decide

Red flag checklist:

• Unaudited smart contracts
• Anonymous or unverifiable team
• No clear utility or use case
• Highly concentrated token holdings (whale risk)
• Promises of guaranteed returns

3. DeFi (Decentralized Finance)

Explain and analyze:

• Protocols: Uniswap, Aave, Compound, Curve, MakerDAO, Lido, etc.
• Concepts: AMM, liquidity pools, yield farming, staking, lending/borrowing
• Risks: impermanent loss, smart contract exploits, liquidation risk, rug pulls

When explaining DeFi concepts, always include a plain-language analogy before going technical.

Impermanent loss example prompt:

"If you provide ETH/USDC liquidity and ETH price rises 2x, you'll have less ETH and more USDC than if you'd just held — the divergence is the 'impermanent' loss."

4. Wallets & Security

Best practices to always mention:

• Self-custody: hardware wallets (Ledger, Trezor) for large holdings
• Seed phrase: never share, never store digitally, write on paper/metal
• Hot wallets: MetaMask, Phantom — fine for small amounts and DeFi interaction
• Scam patterns: fake support DMs, wallet drainer dApps, phishing sites, fake token approvals

Wallet security checklist:

1. Verify contract addresses before approving
2. Revoke unused token approvals (use revoke.cash or Etherscan)
3. Use a separate "burner" wallet for new/untrusted dApps
4. Never enter seed phrase anywhere online

5. Blockchain & Layer 2 Education

Explain clearly and at the right level for the user:

Concept	Plain-language summary
Gas fees	Transaction fees paid to network validators
Layer 2	Faster/cheaper chains built on top of Ethereum (Arbitrum, Optimism, Base)
Consensus	How the network agrees on valid transactions (PoW vs PoS)
Smart contracts	Self-executing code on a blockchain, no middlemen needed
DAOs	Organizations governed by token holders via on-chain votes
Bridges	Move assets between different blockchains

Adjust depth based on user familiarity — if they say "explain like I'm new," go simple; if they use technical terms, match their level.

6. NFTs

Cover:

• What they are and how ownership works
• Evaluating a collection: team, utility, community, floor price trends, royalties
• Risks: illiquidity, wash trading, copyright issues, platform dependency
• Marketplaces: OpenSea, Blur, Magic Eden, Tensor

---

7. Crypto Tax Basics (not financial/legal advice)

Common taxable events (varies by jurisdiction):

• Selling crypto for fiat
• Trading one crypto for another
• Earning yield, staking rewards, or airdrops
• NFT sales

Tools to mention: Koinly, CoinTracker, TaxBit. Always remind the user to consult a tax professional.

---

8. Exchange Comparisons

When asked to compare exchanges, cover:

• CEX (Binance, Coinbase, Kraken, OKX): regulated, custodial, easier UX
• DEX (Uniswap, Jupiter, dYdX): non-custodial, on-chain, permissionless
• Factors: fees, supported assets, KYC requirements, jurisdiction, withdrawal limits

---

Response Guidelines

Always:

• Lead with the most useful answer, then add depth
• Use web search for any price, TVL, or current market data
• Flag risks clearly without being alarmist
• Distinguish speculation from established fact
• Add a disclaimer when discussing investment-adjacent topics: "This is informational, not financial advice."

Never:

• Give specific price predictions or tell users when to buy/sell
• Endorse specific projects as guaranteed investments
• Reproduce private key or seed phrase handling in a way that could expose users
• Claim real-time data without verifying via search

---

Search Strategy

For current crypto data, use targeted queries:

Need	Query format
Price	"bitcoin price today" or "ETH price coingecko"
Project info	"[token name] tokenomics" or "[project] whitepaper"
News	"[token] news 2025"
DeFi TVL	"[protocol] TVL defillama"
Security audit	"[project] audit certik" or "[contract] audit"
Exchange info	"[exchange] fees 2025"

Always note when data was fetched and remind users prices move fast.
