What exactly leaves Base as ETH?
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.
What exactly arrives on Ethereum as ARB?
ARB is a contract representation on Ethereum at 0xb50721bcf8d664c30412cfbc6cf7a15145234ad1. ETH, not ARB, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Why does the ETH to ARB direction matter?
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. On receipt, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
What changes between the source and destination asset roles?
ETH is the deposited native-asset input; ARB is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending ETH?
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. 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 Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
What funds the Base source transaction?
ETH is the native gas asset for Base. 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. ETH is recorded as native on this source.
What is the most dangerous wrong-network mistake here?
Sending ETH on a network other than Base, or using an address that is not valid for Ethereum, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap ETH on Base to ARB on Ethereum without KYC?
Requirements are checked for the live ETH Base to ARB Ethereum 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.
