Privacy on this networkOptimism is a public blockchain network. Confidentiality on Optimism: Vendor-gated privacy.
Privacy on the OP Stack arrived in April 2026 through Sunnyside Labs' Privacy Boost, a hybrid of ZK proofs and trusted execution offering confidential transfers and sanctions screening. It runs on OP Mainnet for that vendor's customers rather than as a protocol default, and nothing privacy related sits in the OP Stack or Superchain standards. So the guarantee rests on one vendor's hardware assumptions on top of a transparent base layer.
