Prices polled every 12s from public RPCs; the 10-block prediction uses exponential smoothing over the in-memory window (α = 0.3). This is a preview of the full gas-oracle library, which uses EMA + linear regression over a 50-block history window and returns a confidence interval. Blob-fee formula follows EIP-4844: blob_base_fee = fake_exponential(MIN_BASE_FEE_PER_BLOB_GAS, excess_blob_gas, BLOB_BASE_FEE_UPDATE_FRACTION).
