What makes Optimism fees lower than Ethereum?

Optimism batches transactions and posts compressed data to Ethereum L1. Users share the L1 calldata cost, resulting in 5–10x fee savings versus mainnet.

What is the Bedrock upgrade's effect on fees?

The Bedrock upgrade reduced Optimism fees by ~40% by improving compression and removing unnecessary data from L1 batch submissions.
