Swap ETH from Arbitrum One to USDT on Polygon

Swap ETH from Arbitrum One to USDT on Polygon. Native ETH leaves Arbitrum One and Polygon USDT arrives on Polygon.

Spend the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH. Chain id 42161, Arbiscan, not Nova. Leave gas. Receive Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on Polygon, six decimals. Polygonscan is the explorer. That is not Circle USDC. Chain id 137, fees in POL, blocks about 2 seconds. The block interval is not a delivery clock.

Tether on Polygon is its own contract

0xc2132D05D31c914a87C6611C10748AEb04B58e8F is the USDT to verify. Arbitrum Tether, 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, is not what you spend and not what you receive. You spend native ETH. Six decimals on the way in mean a familiar dollar unit, not a familiar asset. Price still moves because ETH is the thing being sold. Read the minimum USDT again if the quote ages.

The max button spends your fee

Native ETH on chain id 42161 is both inventory and gas. Keep a cushion. Wrapped ether will not fill in. If you unwrap WETH to reach this route, that unwrap is an extra transaction and also costs ETH. Do it only when the unwrapped balance is truly what you mean to sell.

Dollars that cannot pay POL

After USDT arrives, transfers on Polygon need POL. A MATIC label is that native coin in many wallets. This output is an ERC-20, not the sentinel. How to bridge assets between chains is useful before you empty Arbitrum ETH and discover chain id 137 cannot sign.

Wrong stablecoin, wrong gas coin, wrong wrap

This is not Circle's 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 and not USDC.e. It is not Polygon WETH and not POL. It is not a way to keep ETH. It is the wrong page on Nova and the wrong page if the source balance is WETH rather than the sentinel. Before you sign, compare 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE with 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on their explorers and stop if either address on the quote differs. A stale minimum is a reason to ask for a fresh quote rather than signing the old one. The destination fee token is a different balance from the one this route can credit.

Frequently asked questions

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

Spend the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH. Chain id 42161, Arbiscan, not Nova.

Is Polygon USDT the Arbitrum Tether contract?

No. You can receive 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on Polygon. Arbitrum Tether is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, and you are not spending it. You spend native ETH on chain id 42161. Confirm the receive token on Polygonscan. Six decimals do not make the addresses interchangeable. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Will I have POL to move this USDT?

Not from this quote. POL is the gas coin on chain id 137, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. USDT is an ERC-20. Wallets may say MATIC for the gas row. Fund it separately. You must also reserve ETH on Arbitrum One because you are selling the fee coin. About 2 seconds is a block time, not a gas delivery.

What if I wanted Circle USDC instead?

Then this page is wrong. Native Circle USDC on Polygon is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. USDC.e is yet another contract. This output is Tether. Check the quote's receive address against Polygonscan before you sign, and switch routes if the issuer does not match the app you are funding.
