# Base Blockchain Skill Query Base (Ethereum L2) on-chain data enriched with USD pricing via CoinGecko. 8 commands: wallet portfolio, token info, transactions, gas analysis, contract inspection, whale detection, network stats, and price lookup. No API key needed. Uses only Python standard library (urllib, json, argparse). --- ## When to Use - User asks for a Base wallet balance, token holdings, or portfolio value - User wants to inspect a specific transaction by hash - User wants ERC-20 token metadata, price, supply, or market cap - User wants to understand Base gas costs and L1 data fees - User wants to inspect a contract (ERC type detection, proxy resolution) - User wants to find large ETH transfers (whale detection) - User wants Base network health, gas price, or ETH price - User asks "what's the price of USDC/AERO/DEGEN/ETH?" --- ## Prerequisites The helper script uses only Python standard library (urllib, json, argparse). No external packages required. Pricing data comes from CoinGecko's free API (no key needed, rate-limited to ~10-30 requests/minute). For faster lookups, use `--no-prices` flag. --- ## Quick Reference RPC endpoint (default): https://mainnet.base.org Override: export BASE_RPC_URL=https://your-private-rpc.com Helper script path: ~/.hermes/skills/blockchain/base/scripts/base_client.py ``` python3 base_client.py wallet <address> [--limit N] [--all] [--no-prices] python3 base_client.py tx <hash> python3 base_client.py token <contract_...
