eth_gasPrice on Optimism
Returns the node's current gas-price estimate in wei. On EIP-1559 chains, prefer eth_maxPriorityFeePerGas plus the block base fee for accurate pricing.
A single legacy number that approximates base+tip and tends to overpay on EIP-1559 chains. For accurate pricing, build maxFeePerGas from the block base fee plus eth_maxPriorityFeePerGas.
