To retrieve Base blockchain wallet balances with USD pricing, fetch ETH balances and ERC-20 token holdings via RPC, then enrich them using CoinGecko market prices. This yields a complete portfolio view with total USD value.

Yes, you can inspect Base transaction gas fees and decoded ERC-20 transfers by retrieving transaction fields and gas metrics, estimating L2/L1 fee context, and decoding ERC-20 transfer events directly from transaction logs.

Querying Base network stats does not strictly require a custom RPC endpoint because it defaults to the mainnet URL, but you can override the connection using the BASE_RPC_URL environment variable for custom network access.

To detect a Base proxy contract implementation, resolve the EIP-1967 standard storage slot to identify the underlying logic contract address. This also helps detect if an address is a contract and identify common token interfaces.

Whale detection in Base transaction analysis is the process of identifying large transfers within the latest block. It monitors network health and surfaces significant token movements for on-demand operational intelligence.

CoinGecko rate-limit retry behavior for token pricing works by automatically retrying HTTP price queries when the API responds with a rate limit error, ensuring reliable USD enrichment during Base wallet portfolio retrieval.
