Arbitrum is rolling out confidentiality features designed to give businesses more control over sensitive onchain operations. The platform allows organizations to protect private transaction data while maintaining the option to selectively share information with customers, partners, auditors, and regulators. Key capabilities include: - **Configurable privacy controls** for transaction flows and treasury activity - **Built-in compliance tools** with screening, monitoring, and access controls - **Selective disclosure** mechanisms for regulatory requirements The features are part of Arbitrum's broader push into enterprise adoption, alongside a pilot program with LG Electronics for an onchain advertising network. The approach aims to address a common business concern: how to leverage blockchain's efficiency without exposing commercially sensitive data or sacrificing regulatory compliance. Arbitrum positions these tools as infrastructure-level solutions rather than add-ons, allowing businesses to define privacy and compliance policies directly into their blockchain operations.
