Choose the ETH asset and Base network you currently hold.
Check the estimated output, fees, timing, and Arbitrum destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
Ethereum is classified as a native asset for this route. ETH uses a native asset on Base. The recorded Base representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
This route crosses two L2 execution environments. Base settles to ethereum, while Arbitrum settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
Ethereum is classified as a native asset for this route. ETH uses a native asset on Arbitrum. The recorded Arbitrum representation uses 18 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Arbitrum. EVM 0x account address An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately.
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.
Route-specific mistakes include sending on a network other than Base; using a destination that is not valid for Arbitrum; running out of ETH before the source transaction is submitted. 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. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Base wallet, token-transfer, contract, log, and gas activity remain public, and Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Base to ETH on Arbitrum 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.
ETH is listed as the native representation on Base; ETH is used for network gas. 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. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
ETH is listed as the native representation on Arbitrum; ETH is used for network gas. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
No. This bridge keeps the asset intent while moving between a native ETH and a native ETH. Match the source and output details in the live quote.
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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. The bridge output does not automatically fund every later gas need.
EVM 0x account address Do not substitute a Base address merely because a wallet displays both networks.
Sending on a network other than Base, selecting a representation not listed by the quote, or entering an address invalid for Arbitrum can prevent normal detection or receipt.
Requirements are checked for the live ETH Base to Arbitrum 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.
