# EVM Blockchain Skill Query EVM-compatible blockchain data across 8 chains with USD pricing. 14 commands: wallet portfolio, token info, transactions, activity, gas tracker, network stats, price lookup, multi-chain scan, whale detection, ENS resolution, allowance checker, contract inspector, and transaction decoder. Supports 8 chains: Ethereum, BNB Chain (BSC), Base, Arbitrum One, Polygon, Optimism, Avalanche (C-Chain), zkSync Era. No API key needed. Zero external dependencies — Python standard library only (urllib, json, argparse, threading). > **Supersedes the standalone `base` skill.** Base-specific tokens (AERO, DEGEN, > TOSHI, BRETT, WELL, cbETH, cbBTC, wstETH, rETH) and all Base RPC functionality > previously living under `optional-skills/blockchain/base/` have been folded > into this skill. Pass `--chain base` to any command for Base coverage. --- ## When to Use - User asks for a wallet balance or portfolio on any EVM chain - User wants to check the same wallet across ALL chains at once - User wants to inspect a transaction by hash (or decode what it did) - User wants ERC-20 token metadata, price, supply, or market cap - User wants recent transaction history for an address - User wants current gas prices or to compare fees across chains - User wants to find large whale transfers in recent blocks - User asks to resolve an ENS name (vitalik.eth) or reverse-lookup an address - User wants to check if a contract has dangerous token approvals - User wants to inspect a ...
