How the Sasquatch deposit route works

1. Select the source

Choose the ETH asset and Optimism network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and ZKsync Era destination network.

3. Create the order

Open the live route and follow the exact deposit instructions.

4. Track delivery

Use the receipt and status page until the destination funds arrive.

What you need to know

ETH source representation

Ethereum is classified as a native asset for this route. ETH uses a native asset on Optimism. The recorded Optimism representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

Optimism to zkSync Era L2 handoff

This route crosses two L2 execution environments. Optimism settles to ethereum, while zkSync Era settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

ETH destination representation

Ethereum is classified as a native asset for this route. ETH uses a native asset on zkSync Era. The recorded zkSync Era representation uses 18 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

zkSync Era receipt-side execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on zkSync Era. EVM 0x account address A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Optimism deposit-side execution

Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Optimism. EVM 0x account address An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay.

Optimism to zkSync Era bridge mistakes

Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for zkSync Era; running out of ETH before the source transaction is submitted. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Private Route for ETH → ETH

Optimism wallet, token-transfer, contract, log, and gas activity remain public, and ZKsync Era wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Optimism to ETH on ZKsync Era 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.

Optimism to ZKsync Era FAQs

What ETH representation leaves Optimism?

ETH is listed as the native representation on Optimism; ETH is used for network gas. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

What ETH representation arrives on zkSync Era?

ETH is listed as the native representation on zkSync Era; ETH is used for network gas. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Does the same ETH ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a native ETH and a native ETH. Match the source and output details in the live quote.

Which gas balances matter for this bridge?

An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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 bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Optimism address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Optimism, selecting a representation not listed by the quote, or entering an address invalid for zkSync Era can prevent normal detection or receipt.

Can I bridge ETH from Optimism to ZKsync Era without KYC?

Requirements are checked for the live ETH Optimism to ZKsync Era 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.
