Privacy considerations for SOL to LINK
Where offered, Private Route is designed to reduce an obvious direct association between the sending wallet and received assets; it does not make SOL on Polygon or LINK on Scroll activity anonymous or invisible. Polygon exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Polygon PoS uses an EVM sidechain architecture with its own validator checkpoints and gas balance. Its token representations and bridge behavior are separate from Ethereum L1 even when wallets use the same 0x account. 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. Native SOL pays Solana fees and participates in the Solana account model. Wrapped SOL is an SPL token account representation and tokenized SOL on another network is not native SOL. LINK is an oracle-network utility token represented by network-specific contracts. It is not the gas asset on Ethereum or EVM rollups, and bridged LINK contracts require separate verification. Token contracts, approvals, wallet reuse, recognizable amounts, close timing, and later consolidation can create association signals. Private routing changes only part of that observable transaction context. Identity-verification requirements are separate and must be checked in the live flow.
What remains visible on Polygon
Polygon exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Polygon PoS uses an EVM sidechain architecture with its own validator checkpoints and gas balance. Its token representations and bridge behavior are separate from Ethereum L1 even when wallets use the same 0x account. POL is the native gas asset for Polygon. Reusing the sending address, approval pattern, or recognizable amount can preserve source-side context.
What remains visible on Scroll
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. Receiving-address reuse, immediate consolidation, and later transfers can create destination-side associations.
Polygon source role versus Scroll destination role
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Those source-side events remain visible. 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. That receipt and later destination activity remain visible.
Polygon and Scroll keep separate account histories
The same-looking 0x wallet syntax does not combine the two ledgers. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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. 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. Rollup inclusion and settlement can also expose different timing milestones.
SOL fee-payer and account evidence; LINK approval and governance-token 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. Those source events remain 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 receipt and later destination use remain public.
What Private Route changes—and what it does not
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 Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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. 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 and provider policy for this exact route
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 Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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. 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.
