What you need to know
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.
Select a Scroll-compatible output
EVM 0x account address ETH is the native gas asset for Scroll. The quote identifies whether the delivered asset is native, contract-based, or bridged.
Scroll receipt-side execution
Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Scroll. EVM 0x account address A Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll.
Optimism to Scroll bridge mistakes
Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Scroll; 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. A Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll.
Private Route for USDC → USDC
Optimism wallet, token-transfer, contract, log, and gas activity remain public, and Scroll wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on Optimism to USDC on Scroll 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 Scroll FAQs
Which asset can travel from Optimism to Scroll?
The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit Scroll output before depositing.
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 Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. 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 Scroll can prevent normal detection or receipt.
Can I bridge USDC from Optimism to Scroll without KYC?
Requirements are checked for the live USDC Optimism to Scroll 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.
