Chain-agnostic privacy coprocessor for confidential on-chain transactions
Bubble is Soda Labs' privacy layer for public blockchains. Built on garbled-circuit MPC, it processes developer-defined workloads from different chains without exposing the underlying private data publicly or to Soda Labs, supporting confidential transfers, private and non-linkable balances, and privacy-preserving portfolio and treasury management. Authorized parties can request scoped decryption for compliance, and a Bubble Validator Network lets participants verify that private computations were performed faithfully. It is live on COTI, Ethereum, Polygon, Arbitrum and Base, with Optimism, BSC, Avalanche, XDC and Solana listed as coming next.
