Nullmask does not require any change in user behavior. Users continue using the wallets and workflows they are already accustomed to. The protocol installs as a new EVM network and operates transparently within the wallet.
Nullmask does not require any code modifications in wallets. It simply installs as a new EVM network and already works in MetaMask and any wallet that supports custom RPC endpoints and EIP-1559 transactions.
Spending authority never leaves the wallet. Unlike other privacy protocols that extract private keys or require custom signing, Nullmask authorizes shielded transactions using standard EIP-1559 transactions. This makes the protocol more resilient to phishing attacks.
Most privacy solutions extract spending authority from the wallet. Nullmask does not — the spending authority never leaves the wallet.
Nullmask authorizes shielded transactions using standard EIP-1559 transactions, which are already implemented in every hardware wallet. No modifications to the wallet's code are needed.

MegaETH
Base
BSC
Every deposit is screened by chain analysis tools before approval. The guard service ensures illicit funds cannot enter the privacy pool. A novel revocation key mechanism enables retrospective taint recovery if deposits are flagged after approval.
Shield any whitelisted ERC-20 token alongside native ETH. The protocol supports fee-on-transfer tokens with automatic delta-accounting.
