SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

It removes the need for manual blockchain research by answering Base (Ethereum L2) questions—like wallet balances, token details, transaction contents, and gas costs—in one place with USD enrichment.

Core Features & Use Cases

  • Wallet portfolio + token holdings: Retrieves ETH balance and a set of well-known Base ERC-20 holdings for an address, optionally enriched with CoinGecko USD prices.
  • Transaction inspection: Pulls a transaction and receipt, calculates L2/L1 fees, and decodes common ERC-20 transfer events from logs.
  • Token, contract, and gas analysis: Fetches ERC-20 metadata and total supply, detects EOA vs contract plus ERC interface support and proxy implementation (EIP-1967), and estimates L2 gas costs with L1 context notes.
  • Whale detection and network stats: Scans the latest block for large transfers and summarizes current network health plus ETH/USD.

Quick Start

Ask: get the Base portfolio for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 with USD values and the top 20 tokens.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check a Base blockchain wallet portfolio with USD pricing for ERC-20 tokens?▼

To check a Base wallet portfolio with USD pricing, retrieve the ETH balance and well-known ERC-20 token holdings for an address, then enrich the values using live CoinGecko USD prices for an aggregate portfolio valuation.

Can I inspect a Base L2 transaction and see decoded ERC-20 transfer events?▼

Yes, you can inspect a Base L2 transaction by pulling the transaction and receipt, calculating L2 and L1 fees, and decoding common ERC-20 transfer events directly from the transaction logs.

How do I estimate Base gas costs and get L1 fee context?▼

Estimate Base gas costs by fetching L2 transaction gas estimates while also retrieving L1 context notes, which explain the additional data availability fees inherent to Ethereum L2 networks.

How do I detect whale transfers on the Base network?▼

Detect whale transfers on the Base network by scanning the latest block for large ERC-20 token transfers, allowing you to identify significant on-chain movements and wallet activity.

Does this Base blockchain analytics tool detect proxy contracts and ERC interface support?▼

Yes, it detects whether an address is an EOA or a contract, checks for ERC interface support, and identifies proxy contract implementations following the EIP-1967 standard on the Base network.

What do I need to query Base RPC and retrieve blockchain data?▼

You need a valid Base wallet address or transaction hash to query the Base RPC node, and the helper script runs using only the Python standard library without external dependencies.
