Privacy considerations for SUI to WBTC
Where offered, Private Route is designed to reduce an obvious direct association between the sending wallet and received assets; it does not make SUI on Solana or WBTC on Scroll activity anonymous or invisible. 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. 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. SUI is the native coin used for gas in Sui’s object-centric Move model. A token carrying the SUI ticker outside that object model is not a native Sui coin object. WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. Wrapped assets depend on a token contract and a separate underlying asset model. Wrapper interactions, approvals, unwrap activity, and the destination representation can remain public and may create additional association points. Identity-verification requirements are separate and must be checked in the live flow.
What remains visible on Solana
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. SOL is the native gas asset for Solana. 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.
Solana source role versus Scroll destination role
A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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.
Solana source activity and EVM delivery remain inspectable
Solana exposes the source signature, accounts, mint or native balance changes, programs, and SOL fee. Scroll exposes the destination 0x account, token contract or native receipt, logs, and later gas funding.
Wrapper activity can add another association point
Wrapped-token approvals, transfers, and later unwrap activity are public contract events. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
SUI coin-object evidence; WBTC custody-wrapper evidence
SUI coin-object changes, ownership, gas, and later Move interactions remain public on Sui. Tokenized SUI on another ledger creates a different public record. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. Those source events remain public. WBTC approvals, wrapper-contract transfers, custodian-linked mint or burn context, and later unwrap activity remain public. No native Bitcoin UTXO is hidden by a WBTC token transfer. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path. The receipt and later destination use remain public.
What Private Route changes—and what it does not
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 SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Verification and provider policy for this exact route
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 SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
