About

Soda Labs is a privacy infrastructure company building tools for banks and payment firms to move regulated money on public blockchains while preserving privacy on transaction details such as balances, amounts, and counterparties. The company developed Bubble, a chain-agnostic coprocessor that uses garbled-circuit multiparty computation to perform calculations on encrypted data without exposing sensitive information. Bubble is currently active on Ethereum, Arbitrum, Base, and Polygon, with Solana integration planned. Soda Labs has achieved significant performance improvements, processing 500 confidential transactions per second on Arbitrum with three granted US patents and audited security.
