FAQPage Schema

How do I fetch Base chain wallet balances and ERC-20 token holdings with USD pricing?▼

You can fetch Base wallet balances and USD pricing by running a Python standard-library CLI that batches RPC calls to a Base endpoint and retrieves market valuations via CoinGecko.

Do I need an API key to query Base network stats and transaction data?▼

No, you do not need an API key to query Base network stats. The tool retrieves transaction data and network health metrics directly through a Base RPC endpoint and CoinGecko without requiring authentication.

Can I trace transactions and detect whale movements on the Base L2 network?▼

Yes, you can trace transactions and detect whale movements on the Base L2 network by applying the tool's transaction tracing and whale detection features to the on-chain data fetched via batch RPC calls.

What is the best way to inspect Base smart contracts and analyze gas usage?▼

The best way to inspect Base smart contracts and analyze gas usage is using a Python CLI that performs contract inspection and gas analysis directly against a Base RPC endpoint without requiring external API keys.

Does this Base chain data tool work without installing external Python dependencies?▼

Yes, this Base chain data tool works without external Python dependencies because it runs entirely on the Python standard library, executing batch RPC calls to fetch on-chain data and USD pricing.

What limitations exist when fetching live Base network health and token metadata via RPC?▼

A limitation of fetching live Base network health and token metadata via RPC is dependence on public endpoint reliability and CoinGecko pricing availability, which may affect real-time data accuracy during high network congestion.
