Privacy projectSoda Bubble supportBubble: Enterprise confidential finance. Built by Soda Labs. Technology: garbled-circuit MPC.
Privacy-preserving portfolio management and confidential transactions across any L1, L2 and cross-chain operation. Garbled-circuit MPC with NIST-standard AES-256, measured at roughly 500 confidential transactions per second sustained, end to end, at about 14 cents per million transfers, so confidentiality is not paid for in latency or in fees. Contracts stay standard EVM, nothing has to be rewritten, and disclosure is governed by the contract rather than by an operator. The same engine runs in production on COTI, where it has more than 125 million transactions behind it. Live on Ethereum, Polygon, Arbitrum, Base and COTI.

What is garbled-circuit mpc?
Several parties jointly evaluate a function over encrypted inputs using garbled circuits and secret sharing, so no single party ever holds the plaintext.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
