COTI's V2 mainnet has run a garbled-circuit confidential EVM since March 2025, the first on-chain implementation of the technique, built with Soda Labs. Contracts stay Solidity, privacy arrives as parameters rather than a rewrite, and selective disclosure is built in. The live surface includes COTI's Privacy Portal with seven private ERC-20s and a confidential MetaMask Snap. The honest limit is reach: the privacy is real but confined to COTI's own chain, and the multichain Privacy-on-Demand plan has not shipped yet.
Bubble on COTI
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.
