BNB Smart Chain method guide

Last updated:

eth_feeHistory returns recent fee-market observations ending at a selected BNB Smart Chain block.

The response contains the oldest block in the window, base-fee quantities, gas-used ratios, and optional reward rows for the requested percentiles. Quantities are hex encoded; gas-used ratios are numbers between zero and one.

Use it to build fee suggestions from a block window. For a single current gas-price estimate use eth_gasPrice; for a single priority-fee estimate use eth_maxPriorityFeePerGas.
