What you need to know
Scroll deposit-side execution
Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Scroll. EVM 0x account address A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.
Select a Optimism-compatible output
EVM 0x account address ETH is the native gas asset for Optimism. The quote identifies whether the delivered asset is native, contract-based, or bridged.
Optimism receipt-side execution
Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Optimism. EVM 0x account address An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance.
Scroll to Optimism bridge mistakes
Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for Optimism; running out of ETH before the source transaction is submitted. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance.
Private Route for USDC → USDC
Scroll wallet, token-transfer, contract, log, and gas activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on Scroll to USDC on Optimism 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.

Scroll to Optimism FAQs
Which asset can travel from Scroll to Optimism?
The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit Optimism output before depositing.
Which gas balances matter for this bridge?
A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. 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 Scroll address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Scroll, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Can I bridge USDC from Scroll to Optimism without KYC?
Requirements are checked for the live USDC Scroll to Optimism 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.
