web3-data

Two services in one skill: (1) Web3 on-chain data via Chainbase CLI — use when the user asks about blockchain data, token holders, wallet addresses, token prices, ENS domains, transactions, DeFi portfolios, or any on-chain analytics. Triggers: "top holders of", "who holds", "wallet address", "token price", "token transfers", "ENS domain", "on-chain data", "blockchain query", "SQL query on-chain", across Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Avalanche, zkSync, and other EVM chains. (2) Crypto social intelligence via Tops (chainbase tops) — use when the user asks about trending crypto narratives, social mentions, Twitter/X crypto discussions, narrative discovery, topic heat, or KOL/community signals. Triggers: "trending topics", "crypto narrative", "what's trending in crypto", "social mentions", "who is talking about", "crypto twitter", "KOL signals", "narrative search", "topic posts".

Web3 Data Explorer (Chainbase)

Query on-chain data via the Chainbase CLI.

Quick Reference

Install: npm install -g chainbase-cli (or use npx chainbase-cli)

Auth: Set API key via chainbase config set api-key YOUR_KEY, or env CHAINBASE_API_KEY. Falls back to demo key. If rate-limited, direct user to https://platform.chainbase.com to get a key.

x402 Payment: Supports pay-per-call micropayments via --x402 flag. Setup: chainbase config set private-key 0x...

# Top token holders
chainbase token top-holders 0xdAC17F958D2ee523a2206206994597C13D831ec7 --chain 1 --limit 10

# Token price
chainbase token price 0xdAC17F958D2ee523a2206206994597C13D831ec7

# ENS resolve
chainbase domain ens-resolve vitalik.eth

# SQL query
chainbase sql execute "SELECT * FROM ethereum.blocks ORDER BY number DESC LIMIT 5"

Use --json for machine-parseable output. Use --chain <id> to target a specific chain.

Chain IDs

ChainIDChainID
Ethereum1Optimism10
BSC56Base8453
Polygon137zkSync324
Avalanche43114Arbitrum42161

Default to Ethereum (chain 1) unless user specifies otherwise.

Routing Logic

Match user intent to the right CLI command:

User wantsCLI command
Latest block numberchainbase block latest
Block detailschainbase block detail <number>
Transaction detailchainbase tx detail <hash>
Wallet transaction historychainbase tx list <address>
Token info (name, symbol, supply)chainbase token metadata <contract>
Token pricechainbase token price <contract>
Historical token pricechainbase token price-history <contract> --from <ts> --to <ts>
List of holder addresseschainbase token holders <contract>
Top token holders / who holds a tokenchainbase token top-holders <contract>
Token transfer historychainbase token transfers --contract <addr>
Native token balance (ETH/BNB)chainbase balance native <address>
ERC20 token balances of walletchainbase balance tokens <address>
DeFi portfolio positionschainbase balance portfolios <address>
ENS domains held by addresschainbase domain ens <address>
ENS name → addresschainbase domain ens-resolve <name>
Address → ENS namechainbase domain ens-reverse <address>
Space ID resolve (BSC)chainbase domain spaceid-resolve <domain>
Space ID reverse (BSC)chainbase domain spaceid-reverse <address>
Call smart contract functionchainbase contract call --address <contract> --function "fn" --abi '[...]' --params '[...]'
Anything not covered aboveSQL API: chainbase sql execute "SELECT ..."

Workflow

  1. Identify intent — Determine what data the user needs
  2. Resolve identifiers — If user gives token name (e.g. "USDT"), look up the contract address. Common tokens:
    • USDT: 0xdAC17F958D2ee523a2206206994597C13D831ec7 (ETH)
    • USDC: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (ETH)
    • WETH: 0xC02aaA39b223FE8D0A0e5c4F27eAD9083C756Cc2 (ETH)
    • DAI: 0x6B175474E89094C44Da98b954EedeAC495271d0F (ETH)
    • WBTC: 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 (ETH)
    • If unknown, use chainbase token metadata <contract> or ask the user for the contract address
  3. Select command — Use the routing table above; fall back to SQL API for complex/custom queries
  4. Execute — Run the CLI command. Add --json when you need to parse the output programmatically
  5. Present results — Format data clearly with tables for lists, highlight key insights

Global Options

All commands support these options:

OptionDescriptionDefault
--chain <id>Target chain1 (Ethereum)
--jsonMachine-parseable JSON outputfalse
--page <n>Page number for paginated results1
--limit <n>Results per page20
--x402Enable x402 micropayment modefalse

SQL API Fallback

When CLI commands don't cover the query, translate user intent to SQL:

chainbase sql execute "SELECT from_address, SUM(value) as total FROM ethereum.token_transfers WHERE contract_address = '0x...' GROUP BY from_address ORDER BY total DESC LIMIT 20"

Common table patterns (replace ethereum with chain name):

  • {chain}.blocks — Block data
  • {chain}.transactions — Transactions
  • {chain}.token_transfers — ERC20 transfers
  • {chain}.token_metas — Token metadata
  • {chain}.logs — Event logs

SQL constraints: max 100,000 results per query.

For full command help, run chainbase --help or chainbase <command> --help.


Crypto Social Intelligence (Tops)

Query crypto social signals via chainbase tops. No API key required — free to use.

Service: Tops — trending narratives, topic discovery, Twitter/X mentions. Base URL: https://api.chainbase.com/tops (called internally by the CLI) Rate limit: 10 req/s · 60 req/min · 600 req/hour (per client IP)

Quick Reference

# List trending crypto topics (default: English)
chainbase tops trending
chainbase tops trending --language zh   # Chinese
chainbase tops trending --language ko   # Korean

# Get structured details for a topic
chainbase tops topic <topic_id>

# Get posts/tweets under a topic
chainbase tops posts <topic_id>

# Search narrative candidates by keyword
chainbase tops search "RWA"
chainbase tops search "AI Agent"

# Search recent Twitter/X mentions
chainbase tops mentions "Ethereum ETF"

Use --json for machine-parseable output.

Routing Logic

Match user intent to the right subcommand:

User wantsCLI command
What's trending in crypto right nowchainbase tops trending [--language <lang>]
Details / summary of a specific topicchainbase tops topic <topic_id>
Raw tweets / posts under a topicchainbase tops posts <topic_id>
Find topics related to a narrative keywordchainbase tops search <keyword>
Recent Twitter/X mentions of a project or keywordchainbase tops mentions <keyword>

Workflow

Trend Tracking

  1. chainbase tops trending → get current top topics (note id fields)
  2. chainbase tops topic <id> → dive into summary, keywords, representative tweets
  3. chainbase tops posts <id> → retrieve raw tweets for sentiment analysis

Narrative Discovery

  1. chainbase tops search <keyword> → find candidate topics from a vague term
  2. Cluster/summarize candidates, identify the target topic ID
  3. chainbase tops topic <id> → confirm topic details

Real-time Monitoring

  1. chainbase tops mentions <keyword> → monitor social mentions of a project/token
  2. Extract stance, sentiment, key voices from results

Data Schemas

Story (topic): id, keyword, summary, score, current_rank, rank_status (new/up/down/same), is_new, authors[], tweet_urls[], first_tweet_time, snapshot_time

Tweet: id, text, media_json, user → {user_id, name, screen_name, blue_verified, profile_image}

xlsx

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .xltx, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
