zkBob is a privacy-enhancing smart contract wallet for Web3 that allows for confidential transactions using zero-knowledge proof technology (zk-SNARKs). It enables users to privately send, receive, deposit, and withdraw funds like USDC and ETH on networks such as Polygon and Optimism, while keeping wallet contents and transaction amounts private. The platform incorporates compliance features like daily limits and optional KYC. For developers, zkBob offers an SDK to integrate privacy features into their applications and a direct deposit contract for simplified private payments. The project also includes the BOB stablecoin and is actively promoted by its decentralized team through participation in blockchain conferences and hackathons.
