Privacy for the Polygon to Solana direction
Where offered, Private Route is intended to reduce an obvious direct association between the Polygon sending wallet and Solana receiving wallet; it does not hide either blockchain. POL is the native gas asset for Polygon. EVM 0x account address SOL is the native gas asset for Solana. Base58-encoded Solana account address Similar amounts, timing, address reuse, and later consolidation can still add association signals. Identity requirements must be checked separately.
Polygon source-side visibility
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. The source deposit, gas funding, asset representation, confirmations, and sending-address history remain outside any promise of invisibility.
Solana destination-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 destination delivery and later activity can remain observable even when the provider path reduces a direct association.
Polygon deposit role versus Solana receipt role
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Those deposit-side events remain public. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. The receipt and later activity remain public.
Public EVM deposit and public Solana delivery
Polygon exposes the 0x sender, gas, approvals, and deposit event. Solana exposes the receiving accounts, mint changes, program calls, signature, SOL fee, and later activity. Private Route does not make either record disappear.
WETH wrapper and unwrap evidence; WETH wrapper and unwrap evidence
WETH approvals, wrapper transfers, and later unwrap activity remain visible contract events. A private route does not turn WETH into an unrecorded native ETH balance. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. The source transfer remains public. WETH approvals, wrapper transfers, and later unwrap activity remain visible contract events. A private route does not turn WETH into an unrecorded native ETH balance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. 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 EVM deposit account and Solana receiving account. The 0x transaction, approval, gas, Solana signature, token-account changes, amounts, and timing remain public evidence. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
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 Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
