How the Sasquatch deposit route works

1. Select the source

Choose the USDC asset and Ethereum network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and Optimism 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

From Ethereum L1 into Optimism L2

Ethereum source execution occurs on L1, while Optimism delivery occurs on a separate L2 ledger that settles to ethereum. ETH pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.

Ethereum deposit-side execution

Ethereum is a L1 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Ethereum. EVM 0x account address An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit.

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.

Ethereum to Optimism bridge mistakes

Route-specific mistakes include sending on a network other than Ethereum; using a destination that is not valid for Optimism; running out of ETH before the source transaction is submitted. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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

Ethereum 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 Ethereum 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.

Ethereum to Optimism FAQs

Which asset can travel from Ethereum 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?

An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 Ethereum address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Ethereum, 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 Ethereum to Optimism without KYC?

Requirements are checked for the live USDC Ethereum 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.
