Swap USDT from Arbitrum One to WETH on Polygon

Swap USDT from Arbitrum One to WETH on Polygon. Tether USDT leaves Arbitrum One and Polygon WETH arrives on Polygon.

Tether you sell is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Arbiscan, chain id 42161, not Nova. Fee in ETH. WETH you can receive is 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Polygonscan should show it. It is not POL and not the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Chain id 137 charges POL. Blocks are about 2 seconds. Do not read that as the route's deadline.

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

Ether on Polygon is an ERC-20

There is no native ETH balance on chain id 137. 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 is the contract pools use. This route can credit it. It will not show up as a gas balance, and it will not pay fees. If you paste Ethereum's WETH address into Polygonscan, you are looking at the wrong deployment. Arbitrum WETH is what you are not selling. The input is Tether only.

Six decimals against eighteen

USDT on Arbitrum One uses six decimals. Polygon WETH uses eighteen. Whole tokens on the quote are the safe comparison. The trade is a sale of a dollar token for ether exposure, so the minimum moves. Refresh it. A quiet quote from ten minutes ago is not a promise. Polygon will not lock the ETH price while the message is in flight.

Two fee tokens frame the position

ETH gets the swap off Arbitrum One. POL gets the WETH moving on Polygon. Neither is the output. Wallets that say MATIC mean the native POL gas row. If that row is empty, plan a top-up before you need to unwind. USDT allowance, when required, is on 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, not on the WETH you are receiving.

Wrong for a stablecoin that stays stable

If you wanted Circle USDC on Polygon, including the native contract and not USDC.e, this WETH output is the wrong shape. If you wanted POL, it is wrong. If you wanted to keep Tether, Polygon's USDT contract is a different route. Nova is wrong. So is a same-chain wrap of ETH on Arbitrum One.

Frequently asked questions

Tether you sell is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.

Can Polygon WETH pay gas?

No. Gas is POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 137. WETH is 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You spend Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. An old MATIC label refers to the gas coin, not to this WETH. About 2 seconds is a block interval, not a fee credit. Confirm the address on the explorer before you sign.

Is this WETH the Ethereum contract?

No. Ethereum WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Confirm 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 on Polygonscan, chain id 137. Arbitrum WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and is not the token you sell. The spend is Tether on chain id 42161, not Nova. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Does starting with USDT mean I receive USDT?

No. The output ticker is WETH. Polygon USDT would be 0xc2132D05D31c914a87C6611C10748AEb04B58e8F, and this page does not name it. If you needed a dollar token on Polygon, pick a stablecoin output. The minimum WETH is a market figure and expires with the quote. Confirm the address on the explorer before you sign.
