What LINK representation leaves Arbitrum?
LINK is a contract representation on Arbitrum at 0xf97f4df75117a78c1a5a0dbb814af92458539fb4. ETH, not LINK, pays gas unless both symbols are the same. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.
What LINK representation arrives on Optimism?
LINK is a contract representation on Optimism at 0x350a791bfc2c21f9ed5d10980dad2e2638ffa7f6. ETH, not LINK, 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Does the same LINK ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a LINK contract token and a LINK contract token. Match the source and output details in the live quote.
Which gas balances matter for this bridge?
On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 Arbitrum address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Arbitrum, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Can I bridge LINK from Arbitrum to Optimism without KYC?
Requirements are checked for the live LINK Arbitrum 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.
