What you need to know

Privacy for the Solana to zkSync Era direction

Where offered, Private Route is intended to reduce an obvious direct association between the Solana sending wallet and zkSync Era 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 zkSync Era. 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.

zkSync Era destination-side visibility

zkSync Era exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is a zero-knowledge rollup using EraVM and native account-abstraction features while settling proofs to Ethereum. Execution, fee estimation, and contract compatibility can differ from a byte-for-byte Ethereum assumption. The destination delivery and later activity can remain observable even when the provider path reduces a direct association.

Solana deposit role versus zkSync Era 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. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. 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. zkSync Era separately exposes the destination 0x account, asset receipt, contract logs, and later gas-funded activity.

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. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

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. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Private Route for USDC → USDC

Solana account, token, program, signature, and fee activity remain public, and zkSync Era wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on Solana to USDC on zkSync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Base58-encoded Solana account address and destination-side EVM 0x account address; it does not hide either chain's public records.

Private Solana to zkSync Era Bridge FAQs

What must be verified for a private Solana to zkSync Era bridge?

Check the exact source and destination asset representations, live privacy status, provider, amount, region, source gas, destination address, fees, and any verification request. Standard bridge support is not proof of private availability.

Which Solana bridge records remain public?

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 deposit, gas funding, representation, confirmations, amount, and sending-address history remain observable.

Which zkSync Era records remain public after receipt?

zkSync Era exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is a zero-knowledge rollup using EraVM and native account-abstraction features while settling proofs to Ethereum. Execution, fee estimation, and contract compatibility can differ from a byte-for-byte Ethereum assumption. Delivery and later activity remain observable even if the provider path reduces direct wallet association.

Can the EVM transaction and Solana signature still be compared?

Potentially. They use different ledgers, but amount, timing, token representation, provider observations, address reuse, and later consolidation can still create context.

Does private Solana to zkSync Era bridging guarantee no KYC?

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. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.
