What exactly leaves 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 source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.
What exactly arrives on Base as ETH?
ETH is listed as the native representation on Base; ETH is used for network gas. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Why does the ARB to ETH direction matter?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What changes between the source and destination asset roles?
ARB is the deposited token input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending ARB?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. 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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What funds the Ethereum source transaction?
ETH is the native gas asset for Ethereum. 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. ARB is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending ARB on a network other than Ethereum, or using an address that is not valid for Base, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap ARB on Ethereum to ETH on Base without KYC?
Requirements are checked for the live ARB Ethereum to ETH Base 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.
