What you need to know

WETH input identity and handling

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on zkSync Era. The recorded zkSync Era representation uses 18 decimal places. 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.

Leaving zkSync Era L2 for Ethereum L1

zkSync Era inclusion and its ethereum settlement are distinct from final receipt on Ethereum. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.

WETH unwrap or exchange input check

WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the source token on zkSync Era. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Ethereum destination execution

Ethereum is a L1 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Ethereum. EVM 0x account address An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.

LINK output identity and receiving

Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

zkSync Era source execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on zkSync Era. EVM 0x account address A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum.

EVM-to-EVM execution boundary

zkSync Era and Ethereum can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.

Mistakes specific to WETH zkSync Era to LINK Ethereum

Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Ethereum; running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

Private Route for WETH → LINK

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

Swap WETH on zkSync Era to LINK on Ethereum FAQs

What exactly leaves zkSync Era as WETH?

WETH is a contract representation on zkSync Era with 18 decimals at 0x5AEa5775959fBC2557Cc8789bC1bf90A239D9a91. ETH, not WETH, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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.

What exactly arrives on Ethereum as LINK?

LINK is a contract representation on Ethereum at 0x514910771af9ca656af840dff83e8264ecf986ca. ETH, not LINK, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.

Why does the WETH to LINK direction matter?

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. On 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.

What changes between the source and destination asset roles?

WETH is the deposited token input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending WETH?

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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

Can the wrapped asset pay native network gas?

No. 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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.

What funds the zkSync Era source transaction?

ETH is the native gas asset for zkSync Era. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. WETH is token-tracked and can need approval before transfer.

Can I swap WETH on zkSync to LINK on Ethereum without KYC?

Requirements are checked for the live WETH zkSync to LINK Ethereum quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
