Privacy for the BNB Chain to zkSync Era direction

Where offered, Private Route is intended to reduce an obvious direct association between the BNB Chain sending wallet and zkSync Era receiving wallet; it does not hide either blockchain. BNB is the native gas asset for BNB Chain. EVM 0x account address ETH is the native gas asset for zkSync Era. EVM 0x account address Similar amounts, timing, address reuse, and later consolidation can still add association signals. Identity requirements must be checked separately.

BNB Chain source-side visibility

BNB Chain exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. BNB Smart Chain uses EVM execution with BEP-20 token contracts and BNB for gas. A BEP-20 deposit is not an ERC-20 deposit even when the ticker and 0x address syntax look familiar. The source deposit, gas funding, asset representation, confirmations, and sending-address history remain outside any promise of invisibility.

zkSync Era destination-side visibility

zkSync Era exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is a zero-knowledge rollup using EraVM and native account-abstraction features while settling proofs to Ethereum. Execution, fee estimation, and contract compatibility can differ from a byte-for-byte Ethereum assumption. The destination delivery and later activity can remain observable even when the provider path reduces a direct association.

BNB Chain deposit role versus zkSync Era receipt role

A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. Those deposit-side events remain public. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The receipt and later activity remain public.

Two EVM histories can still be compared

BNB Chain and zkSync Era use separate chain identifiers, balances, contracts, transaction hashes, and gas records even when address syntax matches. Sequencer inclusion and settlement timing can add further observable milestones.

Cross-chain linkability limits

Private routing can reduce an obvious link between two EVM accounts, but source approvals, gas, logs, destination contract or native receipt, and later activity remain on separate chain histories. Sequencer and settlement timing can add correlation evidence. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Verification status is separate from privacy status

The provider must support the exact L2 direction, asset contracts, amount, and region. Rollup support and privacy routing do not imply that identity verification, account, or custody requirements are absent. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Private Route for USDC → USDC

BNB Chain wallet, token-transfer, contract, log, and gas activity remain public, and zkSync Era wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on BNB Chain to USDC on zkSync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
