Arbitrum Adds Private Transfers, Deposits and Balance Checks via NullMask

Privacy tooling arriving on a major Layer 2 matters because transparent balances are a practical barrier for institutions and treasuries that want onchain settlement without exposing positions to competitors. The disclosure gap is the real story: no launch date, fee structure or supported assets means users cannot yet assess cost, liquidity or compliance exposure. Whether NullMask publishes those details, and whether the feature attracts institutional flow rather than just retail privacy demand, is the open question worth watching.
