Swap WETH from Polygon to USDT on Arbitrum One
Swap WETH from Polygon to USDT on Arbitrum One. Polygon WETH leaves Polygon. Tether USDT is what can arrive on Arbitrum One. You are not delivering Arbitrum WETH, and you are not staying in ether.
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Polygonscan records the WETH. Arbiscan records Tether on chain id 42161. Not Nova. POL is required even though the asset is WETH. Arbitrum One will not treat Tether as gas.
Arbitrum Tether is not native USDC
Polygon fee is POL, not this WETH
USDT will not pay Arbitrum
Mainnet WETH is the wrong inventory

Frequently asked questions
What is the best way to swap WETH from Polygon to USDT on Arbitrum One?
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. XAUConnect compares live routes and lets your own wallet sign.
Is 0xFd08 the token I am selling?
No. You sell Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 is Tether on Arbitrum One, chain id 42161, not Nova. Polygonscan shows the first. Arbiscan shows the second. Approving Arbitrum USDT does not move the WETH. Stay on chain id 137 and approve only the Polygon WETH.
Why is Arbitrum WETH unchanged?
Because this quote does not buy 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. ETH is not WETH, and the output is Tether. If you needed the wrapper, stop. Look for USDT on Arbiscan after POL has paid the Polygon fee. Nova will not list it. Mainnet WETH is a different chain and a different contract.
What if I spend my last POL?
The send on chain id 137 fails before Arbiscan has a credit. WETH cannot replace POL. Keep a remainder of the native coin. About 2 second blocks are not a promise about the bridge. The destination still needs ETH later to move the USDT. Fund that ETH before the token has to move.
