NullMask (@NullMaskio) is now live on Arbitrum (@arbitrum) $ARB, bringing its privacy tools to one of Ethereum's largest Layer 2 networks. The launch lets users move funds without exposing the link between deposits and withdrawals on a public ledger.

How NullMask Works on Arbitrum

The protocol lets users deposit $ETH and supported tokens into a shared pool. From there, they can send funds privately, swap assets and withdraw to any address. Users can access NullMask through their existing wallets, so no separate account is needed.

NullMask describes itself as a zero-knowledge (ZK) privacy protocol for private transfers and swaps. In a press release published via The Block, the project said it runs inside the wallets people already use. The release names Tomas Krnak as the founder of NullMask.

Arbitrum also announced the feature. TechFlow reported that Arbitrum said users can now privately deposit, send assets and check balances through NullMask. According to the same report, NullMask had earlier announced that its service had gone live on Arbitrum, supporting private deposits, transfers and withdrawals.

Wider Rollout Across Networks

The launch extends NullMask's reach across Ethereum, Base (@base) and Arbitrum. In its October press release, the project said it was live on Ethereum, Base, BNB Chain and Robinhood Chain, with Solana and private perpetuals listed as coming next. That release also said NullMask had processed more than $50 million in private volume since 1 October.

Separately, Cryptonews reported that NullMask has extended support to Monad ($MON). The outlet said the move gives users on the network a way to keep sending, withdrawing and depositing activity private.

Privacy tooling remains a closely watched area of crypto because public blockchains expose payments, balances and counterparties to anyone with an address. NullMask's own release makes the same point, noting that every payment on a public chain is permanent and searchable. Whether the Arbitrum deployment leads to higher usage has yet to be seen.
