Privacy for the zkSync Era to Scroll direction
Where offered, Private Route is intended to reduce an obvious direct association between the zkSync Era sending wallet and Scroll receiving wallet; it does not hide either blockchain. ETH is the native gas asset for zkSync Era. EVM 0x account address ETH is the native gas asset for Scroll. EVM 0x account address Similar amounts, timing, address reuse, and later consolidation can still add association signals. Identity requirements must be checked separately.
zkSync Era source-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 source deposit, gas funding, asset representation, confirmations, and sending-address history remain outside any promise of invisibility.
Scroll destination-side visibility
Scroll exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is a bytecode-compatible zero-knowledge EVM rollup that proves batches to Ethereum. Scroll inclusion and Ethereum proof settlement are distinct, and its token contracts must be verified independently from L1. The destination delivery and later activity can remain observable even when the provider path reduces a direct association.
zkSync Era deposit role versus Scroll receipt role
A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. Those deposit-side events remain public. A Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. The receipt and later activity remain public.
Two EVM histories can still be compared
zkSync Era and Scroll 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. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. 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. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
