Optimism native transfer fee is $0.0000051 (p50, 24h). Optimism uses an OP Stack EIP-1559 fee market with a near-zero priority fee (single sequencer, no public mempool to bid against); a native ETH transfer is 21000 gas. The L1 blob-posting cost, quoted by the GasPriceOracle predeploy for a 113 byte transfer, is included in this figure and is usually the larger of the two components. Computed via `eth_feeHistory` plus `getL1Fee` on the Optimism RPC times live ETH price.
