Swap ARB from Arbitrum One to USDT on Polygon

Swap ARB from Arbitrum One to USDT on Polygon. ARB leaves Arbitrum One and Polygon USDT arrives here on Polygon.

Governance token 0x912CE59144191C1204E64559FE8253a0e49E6548 is the spend. Arbiscan, chain id 42161, not Nova. Gas is ETH. Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F is the receive, six decimals, on Polygon. Polygonscan is the explorer. It is not Circle USDC and not ARB. Chain id 137, fees in POL, blocks about 2 seconds. Do not treat the block time as a promise.

ARB leaves Arbitrum One. USDT is what can arrive on Polygon.

Tether's Polygon contract, not a bridged guess

Memorize 0xc2132D05D31c914a87C6611C10748AEb04B58e8F if this is the balance you intend to hold. Six decimals. It is not native Circle USDC and not USDC.e. It is not Ethereum Tether. A deposit page that specifies ERC-20 USDT on Ethereum will not credit Polygon USDT. Read the chain on the deposit instructions as Polygon PoS, chain id 137, and match Polygonscan.

The sale ends the vote

ARB you sell is not escrowed for a later proposal. It is not delivered as ARB. The minimum USDT is only as good as the quote. When ARB's price moves, that minimum moves with the next quote. Do not sign a floor you have not reread. Eighteen decimals on ARB versus six on USDT make base-unit math misleading.

Gas is never the governance token

ETH on the way out, POL on the way in for any follow-up. How to bridge assets between chains places the approval on the source. The approval target is 0x912CE59144191C1204E64559FE8253a0e49E6548. If the screen shows WETH or native ETH as the sold asset, you have left this route.

Wrong asset if you needed Circle or ether

Native USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 is a different issuer. WETH and POL are different exposures. This page is wrong for all three, wrong on Nova, and wrong if the point was to keep ARB while changing chains. Before you sign, compare 0x912CE59144191C1204E64559FE8253a0e49E6548 with 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on their explorers and stop if either address on the quote differs. Keep the source fee token in the wallet after you choose the trade size. Sign only on the source chain id named in this article, with the wallet network checked.

Frequently asked questions

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

Governance token 0x912CE59144191C1204E64559FE8253a0e49E6548 is the spend. Arbiscan, chain id 42161, not Nova.

Does this bridge ARB itself onto Polygon?

No. The spend is 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. The receive can be Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Check Polygonscan. You lose voting weight on the amount sold. If the goal was to hold ARB on another chain, this output is the wrong token. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Is Polygon USDT six decimals?

Yes. 0xc2132D05D31c914a87C6611C10748AEb04B58e8F uses six decimals, like Ethereum Tether, but it is not that contract. Read whole tokens on the quote. You still need ETH to sell ARB on chain id 42161, and POL to move USDT on chain id 137. About 2 seconds is a block interval, not a decimal conversion.

Can I pay Polygon fees with the USDT?

No. POL is the gas coin, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Some wallets label it MATIC. This route does not credit it. USDT is an ERC-20 that sits until POL is present. Source gas remains ETH on Arbitrum One, not Nova. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
