Swap USDT from Arbitrum One to USDC on Polygon

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

Sell Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One. Arbiscan, chain id 42161, not Nova. Gas in ETH. Receive native Circle USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygon, six decimals. Polygonscan is the check. That is not USDC.e at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174. Chain id 137, gas in POL, blocks about 2 seconds. The block time is not a credit promise.

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

Native USDC and USDC.e still split Polygon

0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 is Circle's native USDC on Polygon PoS. The older bridged token, USDC.e, is a different contract that many pools still list. This route does not deliver USDC.e. If your destination app has not migrated, the Circle balance will look invisible to it. Check the app's allowlist against Polygonscan before you sell Tether into the wrong dollar.

Same six decimals, different companies

Arbitrum USDT is Tether. Polygon USDC in this quote is Circle. Both show six decimals, so a small fee looks like a small fee rather than a decimal trick. It can still be a real gap. Read the minimum. Do not assume a treasury that accepts Tether will accept Circle, or the reverse. The ticker change is the point of the page.

POL later, ETH now

Receiving USDC does not give you POL. Chain id 137 will not move that USDC for free. Some wallets label POL as MATIC. The sentinel is the gas coin either way, and this output is not the sentinel. How to bridge assets between chains keeps the source approval on Arbitrum One, where ETH pays to move 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9.

Wrong if you needed the bridged dollar

Stop if the app wants USDC.e. Stop if you wanted Polygon USDT at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F, because that would keep Tether's ticker. Stop if you wanted WETH or POL. Stop on Nova. Stop if you confused this Circle address with Arbitrum's own Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831.

Frequently asked questions

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

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

Is 0x3c499c the bridged USDC.e token?

No. 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 is native Circle USDC on Polygon. USDC.e is a different, older contract. This route can credit the native one only. You spend Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One. Confirm the receive page on Polygonscan. If your pool still wants USDC.e, this arrival will not match.

Do I need POL before the USDC is useful?

You need POL, chain id 137, before you can transfer or sell that USDC. This route does not include the gas sentinel. A MATIC label in an old wallet usually means the same native fee token. You also need ETH on Arbitrum One to start.

Are the two stablecoins from the same issuer?

No. Tether issues the USDT you sell. Circle issues the USDC you can receive. Both are six decimals. Neither is Maker DAI. Read the minimum, because a dollar target does not make the quote exactly one for one. Arbiscan is for the spend. Polygonscan is for 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359.
