What you need to know
zkSync Era deposit-side 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.
Select a Base-compatible output
EVM 0x account address ETH is the native gas asset for Base. The quote identifies whether the delivered asset is native, contract-based, or bridged.
Base receipt-side execution
Base is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Base. EVM 0x account address A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
zkSync Era to Base bridge mistakes
Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Base; running out of ETH before the source transaction is submitted. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
Private Route for USDC → USDC
ZKsync Era wallet, token-transfer, contract, log, and gas activity remain public, and Base wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on ZKsync Era to USDC on Base 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.

ZKsync Era to Base FAQs
Which asset can travel from zkSync Era to Base?
The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit Base output before depositing.
Which gas balances matter for this bridge?
A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. 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 zkSync Era address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than zkSync Era, selecting a representation not listed by the quote, or entering an address invalid for Base can prevent normal detection or receipt.
Can I bridge USDC from ZKsync Era to Base without KYC?
Requirements are checked for the live USDC ZKsync Era to Base 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.
