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 LINK?
LINK is a contract representation on Base at 0x88fb150bdc53a65fe94dea0c9ba0a6daf8c6e196. ETH, not LINK, pays gas unless both symbols are the same. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Why does the ARB to LINK 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, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
What changes between the source and destination asset roles?
ARB is the deposited token input; LINK 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 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
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 LINK on Base without KYC?
Requirements are checked for the live ARB Ethereum to LINK 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.
