Privacy on this networkBubble privacy enabledArbitrum is a public blockchain network. Confidentiality on Arbitrum: Bubble live · no native privacy.
Arbitrum's 2026 roadmap sketches three confidentiality models, and its own FAQ confirms network-level confidential execution is not live yet, with the Arbitrum One variant subject to a DAO vote. Today privacy is app layer: Railgun and Fluidkey, plus Renegade's dark pool for matching. Hinkal was exploited for roughly $820,000 in July 2026 and has its contracts paused pending investigation, so it is not a live option right now. This is also where we run our benchmarks: 15,000 private ERC-20 transfers in July 2026, around 500 confidential transactions per second sustained and 750 at peak, measured end to end including chain confirmation.

Bubble on Arbitrum
Confidential transfers run here through the Soda SDK today. Assets stay where they are, the network keeps ordering and settling, and Bubble adds a private environment above it. The public sees that a transaction settled; entitled parties see what they are authorized to see.
Private by design.
