EVM Balance Skills

This skill provides guidance and implementation patterns for fetching EVM balances across multiple chains using the @evm-balance toolkit and Multicall3. It covers both SDK integration and CLI usage.

Features

• High Performance: Fetch native and ERC20 balances using Multicall3 (single RPC call).
• Multi-Chain: Native support for all chains available in viem/chains.
• Dual Address Mode: Support for XPUB (BIP-44) and Factory (CREATE2) derivation.
• Batch Processing: Efficiently query large address ranges with configurable batch sizes.
• Smart Filtering: Filter by minimum balance with correct decimal handling.
