Privacy for the Linea to Arbitrum direction
Where offered, Private Route is intended to reduce an obvious direct association between the Linea sending wallet and Arbitrum receiving wallet; it does not hide either blockchain. ETH is the native gas asset for Linea. EVM 0x account address ETH is the native gas asset for Arbitrum. EVM 0x account address Similar amounts, timing, address reuse, and later consolidation can still add association signals. Identity requirements must be checked separately.
Linea source-side visibility
Linea exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is a zero-knowledge EVM rollup that batches execution and proves state to Ethereum. L2 transaction inclusion, proof completion, and Ethereum settlement are different stages, while token contracts remain specific to Linea. The source deposit, gas funding, asset representation, confirmations, and sending-address history remain outside any promise of invisibility.
Arbitrum destination-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 destination delivery and later activity can remain observable even when the provider path reduces a direct association.
Linea deposit role versus Arbitrum receipt role
A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. Those deposit-side events remain public. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. The receipt and later activity remain public.
Two EVM histories can still be compared
Linea and Arbitrum 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.
Native ETH gas and value evidence; Native ETH gas and value evidence
Native ETH can expose both transfer value and gas funding on the selected network. Rollup balances, Ethereum L1 balances, and WETH contracts remain separate public records. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. The source transfer remains public. Native ETH can expose both transfer value and gas funding on the selected network. Rollup balances, Ethereum L1 balances, and WETH contracts remain separate public records. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees. 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 Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
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 Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
