FAQPage Schema
How do I check Base wallet balances and token holdings with USD values?

To check Base wallet balances with USD values, you can query on-chain data enriched with CoinGecko pricing. This provides fast access to token holdings and their current USD valuations for any Base address without managing multiple tools.

What is the best way to trace ERC-20 and ERC-721 transfers on Base?

Tracing ERC-20 and ERC-721 transfers on Base is handled by querying transaction details with on-chain decoding. The Skill applies batch RPC calls to extract and decode transfer events, optionally adding price context for ERC-20 tokens.

Can I estimate Base gas costs and check network health using an RPC endpoint?

Yes, you can estimate Base gas costs and check network health by querying a Base RPC endpoint. The Skill retrieves real-time network stats and gas cost estimates using live ETH prices fetched from CoinGecko.

Does this on-chain data query tool support contract inspection and token metadata lookups?

Yes, the tool supports Base contract inspection and basic token metadata lookups. It uses on-chain decoding via batch RPC calls to assess contract behavior and retrieve token details directly from the Base network.

How do I analyze whale activity and live network stats on the Base blockchain?

Analyzing whale activity and live network stats on the Base blockchain is done by querying on-chain data with batch RPC calls. The Skill retrieves large transaction traces and real-time network health metrics enriched with USD pricing.

What are the limitations of querying Base on-chain data with CoinGecko pricing?

Limitations include reliance on CoinGecko for USD pricing accuracy and a Base RPC endpoint for data retrieval. The tool implements robust retry handling for RPC failures, but complex contract interactions may not fully decode without specific ABI inputs.
