Privacy for the Solana to Arbitrum direction
Where offered, Private Route is intended to reduce an obvious direct association between the Solana sending wallet and Arbitrum receiving wallet; it does not hide either blockchain. SOL is the native gas asset for Solana. Base58-encoded Solana 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.
Solana source-side visibility
Solana exposes account keys, transaction signatures, token-account changes, program calls, amounts, fees, and timing. It uses an account-and-program execution model with transaction signatures rather than EVM hashes. SPL tokens use mint and token-account records, and a receiving wallet may need the correct associated token account plus SOL for later activity. 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.
Solana deposit role versus Arbitrum receipt role
A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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.
Public Solana deposit and public EVM delivery
The source signature, account keys, token-account changes, programs, and SOL fee remain visible. Arbitrum separately exposes the destination 0x account, SOL receipt, contract logs, and later gas-funded activity.
SOL fee-payer and account evidence; SOL fee-payer and account evidence
Native SOL balance changes, fee-payer accounts, signatures, and later token-account activity remain visible on Solana. Tokenized SOL elsewhere follows a separate contract ledger. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. The source transfer remains public. Native SOL balance changes, fee-payer accounts, signatures, and later token-account activity remain visible on Solana. Tokenized SOL elsewhere follows a separate contract ledger. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native. The destination receipt and later use remain public even when direct wallet association is reduced.
Cross-chain linkability limits
Private routing can reduce a direct association between the Solana source account and EVM receiver. The source signature, program and token-account changes, destination contract logs, gas, amounts, and timing remain public. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Verification status is separate from privacy status
Provider policy is evaluated for the exact Solana mint or native asset, the other network representation, amount, and region. Cross-ecosystem wallet compatibility and no-KYC status are separate checks. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
