Swap USDT from Arbitrum One to POL on Polygon

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

Sell 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, Tether on Arbitrum One. Arbiscan, chain id 42161, not Nova. Keep ETH for the fee. Receive native POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137. Polygonscan shows the account balance. That is not WETH and not a stablecoin. Blocks are about 2 seconds. No fill time is promised by that figure. A wallet may still name this gas coin MATIC.

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

Use this when Polygon cannot pay its own fee

POL is what chain id 137 charges. If you are empty, tokens you already hold there are stuck. This route sells Arbitrum Tether for that gas coin. It does not sell it for WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. It does not mint a BEP-20 lookalike. The sentinel is the native balance. If an exchange wants a contract address, native POL may not be what their form expects.

Tether does not redeem into a fixed POL amount

USDT targets a dollar. POL does not. The minimum on the quote is the bound, and it expires. Six decimals in, eighteen out. Read whole tokens. How to bridge assets between chains is the procedural background. It will not hold the POL price while you compare explorers.

Source network check

The approval, when needed, is Tether on chain id 42161. ETH pays it. Nova will sign against the wrong chain. Arbitrum USDT is not Polygon USDT, so do not expect 0xc2132D05D31c914a87C6611C10748AEb04B58e8F to be the thing you spend. Polygonscan is only the destination side, and only for the POL balance rather than a token page at the sentinel.

Wrong if a dollar balance was the goal

Circle USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 is a different output. So is Polygon USDT. So is WETH. This page is only for native POL. It is the wrong page if you thought the sentinel meant ETH, and the wrong page if you wanted to keep Tether's issuer all the way through.

Frequently asked questions

What is the best way to swap USDT from Arbitrum One to POL on Polygon?

Sell 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, Tether on Arbitrum One. Arbiscan, chain id 42161, not Nova.

Why does my wallet say MATIC if the route says POL?

Polygon's native gas coin is POL. Some wallets still print the older MATIC label for that same balance. The sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 137 is that gas coin, not a separate token and not ETH. You spend Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Confirm the balance on Polygonscan.

Is POL the same as Polygon WETH?

No. WETH is the ERC-20 at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. This route credits native POL instead. WETH will not pay gas. POL will. If you wanted ether exposure, you are on the wrong page. About 2 seconds is a Polygon block interval, not a reason to ignore the ticker.

What do I need on Arbitrum before this works?

Tether at the address above, plus native ETH for gas on chain id 42161, not Nova. POL cannot pay the source fee. You do not approve POL to receive it. If the quote expires, request a new minimum, because POL's price against USDT can move.
