Swap USDC from Polygon to USDT on Arbitrum One
Swap USDC from Polygon to USDT on Arbitrum One. Circle USDC leaves Polygon. Tether USDT is what can arrive on Arbitrum One. The issuer changes, and the destination is not Arbitrum Nova.
Sell 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on chain id 137. Buy 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on chain id 42161. Polygonscan shows the debit. Arbiscan shows Tether. POL pays the source. ETH, not ARB, pays later fees on Arbitrum One. Arbitrum One is the network in the wallet header, not Nova.
Nova is a different network
USDC.e will not sell
Tether is not Circle on arrival
USDT cannot pay Arbitrum

Frequently asked questions
What is the best way to swap USDC from Polygon to USDT on Arbitrum One?
Sell 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on chain id 137. Buy 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on chain id 42161.
Is Arbitrum Nova the same place as this USDT?
No. This credit is on Arbitrum One, chain id 42161, at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Nova is a different network and will not list it. Arbiscan for One is the explorer. You sell Circle USDC on Polygon, chain id 137, not USDC.e. POL pays the source fee. Nova will not list this Tether credit.
Will this USDT pay gas on Arbitrum One?
No. Gas is ETH, not Tether and not the ARB token. This quote does not buy the native ETH label. Keep ETH on chain id 42161 or the new USDT cannot move. There is no published finish time for the bridge leg. Arbiscan shows the token, not a gas stipend.
What if I wanted Circle USDC on Arbitrum?
Then this route is wrong. Native USDC there is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. The older bridged USDC.e is a different contract again. This page buys Tether. Switch the output before you approve 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygonscan. USDC.e is a different Arbitrum contract, not this output. Switch to the native contract before you approve.
