What you need to know

Privacy for the Arbitrum to zkSync Era direction

Where offered, Private Route is intended to reduce an obvious direct association between the Arbitrum sending wallet and zkSync Era receiving wallet; it does not hide either blockchain. ETH is the native gas asset for Arbitrum. 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.

Arbitrum source-side visibility

Arbitrum exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Its Nitro optimistic-rollup design executes through a sequencer and posts compressed transaction data to Ethereum. L2 inclusion and Ethereum settlement are separate milestones, so a source receipt can advance before the rollup state is final on L1. 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.

Arbitrum deposit role versus zkSync Era receipt role

On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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

Arbitrum 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.

LINK approval and governance-token evidence; LINK approval and governance-token evidence

Token allowances, contract transfers, voting or utility interactions, source gas, and later wallet consolidation can remain visible for this deposit. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. The source transfer remains public. Token allowances, contract transfers, voting or utility interactions, source gas, and later wallet consolidation can remain visible for this receipt. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later. The destination receipt and later use remain public even when direct wallet association is reduced.

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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

Private Route for LINK → LINK

Arbitrum 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 LINK on Arbitrum to LINK 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.

Private LINK Arbitrum to zkSync Era Bridge FAQs

What must be verified for a private LINK Arbitrum to zkSync Era bridge?

Check the exact LINK representations, live privacy status, provider, amount, region, source gas, destination address, fees, and any verification request. Standard bridge support is not proof of private availability.

Which Arbitrum bridge records remain public?

Arbitrum exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Its Nitro optimistic-rollup design executes through a sequencer and posts compressed transaction data to Ethereum. L2 inclusion and Ethereum settlement are separate milestones, so a source receipt can advance before the rollup state is final on L1. The deposit, gas funding, representation, confirmations, amount, and sending-address history remain observable.

Which zkSync Era records remain public after receipt?

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. Delivery and later activity remain observable even if the provider path reduces direct wallet association.

Which LINK events remain visible on this private bridge?

LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later. Both the deposit and receipt remain ledger records.
