How the Sasquatch deposit route works

1. Select the source

Choose the DAI asset and Base 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

DAI representation on both sides

DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path. The same stablecoin ticker does not make the two network records or contracts interchangeable.

ETH source gas and ETH destination readiness

A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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.

Base to Optimism L2 handoff

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

Base deposit-side execution

Base is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Base. EVM 0x account address A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger.

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.

Base to Optimism bridge mistakes

Route-specific mistakes include sending on a network other than Base; using a destination that is not valid for Optimism; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. 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 receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Private Route for DAI → DAI

Base wallet, token-transfer, contract, log, and gas activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this DAI on Base to DAI 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.

Base to Optimism FAQs

What DAI representation leaves Base?

DAI is a contract representation on Base with 18 decimals at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb. ETH, not DAI, pays gas unless both symbols are the same. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.

What DAI representation arrives on Optimism?

DAI is a contract representation on Optimism with 18 decimals at 0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1. ETH, not DAI, pays gas unless both symbols are the same. 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 receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Does the same DAI ticker guarantee the same ledger form?

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

Which gas balances matter for this bridge?

A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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 Base address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

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

Can I bridge DAI from Base to Optimism without KYC?

Requirements are checked for the live DAI Base 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.
