# 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.
