Swap ARB from Arbitrum One to WETH on Polygon

Swap ARB from Arbitrum One to WETH on Polygon. ARB leaves Arbitrum One and Polygon WETH arrives here on Polygon.

Sell 0x912CE59144191C1204E64559FE8253a0e49E6548. Confirm ARB on Arbiscan. Chain id 42161, not Nova. Fee in ETH, not in ARB. Receive 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Polygonscan should show WETH, which is not POL and not the sentinel. Chain id 137. Blocks about every 2 seconds. That figure does not schedule the credit or the ARB price.

Diagram for Swap ARB from Arbitrum One to WETH on Polygon — ARB leaves Arbitrum One. WETH is what can arrive on Polygon.

Governance token in, ether token out

You are not wrapping ARB. You are selling it for the WETH contract Polygon pools recognize. That contract is not Arbitrum WETH and not Ethereum WETH. Write down 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and compare Polygonscan. The minimum is a cross rate between two volatile assets. It expires. Voting weight leaves with the ARB.

WETH still cannot start a Polygon transaction

POL pays chain id 137. If you needed the gas coin, the sentinel route is the one that names POL. This page names an ERC-20. A MATIC label in the wallet is a hint you are looking at gas, not at 0x7ceB. Fund POL separately if the next step is a swap or a transfer of the WETH.

Permission lives on the ARB contract

Allowance, when required, is for 0x912CE59144191C1204E64559FE8253a0e49E6548 on chain id 42161, paid in ETH. You do not approve Polygon WETH to receive it. Polygon is only the destination. If the wallet header says Nova during the approval, the signature is on the wrong chain.

Wrong when ARB or a stablecoin should arrive

This output is not ARB, not Circle USDC, not USDT, and not POL. It is the wrong page if you meant to sell Arbitrum WETH rather than ARB. Those tickers sit near each other in a portfolio and fund completely different quotes. Check the spend address every time. Before you sign, compare 0x912CE59144191C1204E64559FE8253a0e49E6548 with 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 on their explorers and stop if either address on the quote differs. A stale minimum is a reason to ask for a fresh quote rather than signing the old one. Gas on the source chain is separate from the asset you hope to receive.

Frequently asked questions

What is the best way to swap ARB from Arbitrum One to WETH on Polygon?

Sell 0x912CE59144191C1204E64559FE8253a0e49E6548. Confirm ARB on Arbiscan. XAUConnect compares live routes and lets your own wallet sign.

Is Polygon WETH native ETH?

No. Chain id 137 does not use ETH as gas. The output is the ERC-20 at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. POL is the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. You sell ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548. Confirm WETH on Polygonscan. It will not pay fees. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Do I keep ARB on Polygon?

No. This is a sale. The governance token stays behind only in the amount you do not spend. Polygon receives WETH, not ARB. If a proposal needs your tokens, lower the trade. Chain id 42161, not Nova, is where the unsold ARB remains. About 2 seconds is a Polygon block, not a voting extension.

Which WETH address is easy to confuse with this one?

Arbitrum WETH 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and Ethereum WETH 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Neither is the receive contract, and neither is the spend. The spend is ARB. The receive is 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Compare full addresses on the two explorers. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
