Swap ARB from Arbitrum One to POL on Polygon

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

Spend 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Arbiscan, chain id 42161, not Nova. ARB does not pay gas, so hold ETH. Receive native POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137. Polygonscan shows the balance. It is not WETH and not a stablecoin. Blocks are about 2 seconds. No promised arrival follows from that. The wallet may still say MATIC.

Sell governance weight for Polygon gas

This pair fits a wallet that has ARB on Arbitrum One and a stuck account on chain id 137. The output can pay Polygon fees. It cannot pay the Arbitrum fee, and it is not 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. If you needed ether exposure, you opened the wrong receive. If you needed ARB to survive, you opened the wrong route entirely.

MATIC on the screen, POL in the quote

The native coin was renamed. Older wallet software often did not follow. The sentinel still means that native balance. You do not approve it to receive it. You do not paste it into a token-import box and expect a supply figure. Watch the account on Polygonscan. If a custodian wants an ERC-20 contract for the deposit, native POL is probably not what they listed.

Price plus a fee you must already hold

ARB against POL is a float. Read the minimum. ETH on chain id 42161 must already be there for the approval of 0x912CE59144191C1204E64559FE8253a0e49E6548. Polygon describes the destination. It does not stock your Arbitrum wallet with ETH.

Wrong ticker, wrong chain, wrong balance

Stop for Circle USDC, USDT, or Polygon WETH. Stop for Nova. Stop if the coins you hold are WETH or native ETH rather than ARB. Stop if you meant a same-chain sale of ARB into ETH on Arbitrum One, which would leave chain id 137 empty of POL.

Frequently asked questions

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

Spend 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.

Is POL the same balance some wallets call MATIC?

Yes, in the usual wallet label. The native gas coin of chain id 137 is POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. It is not a second token beside MATIC. You spend ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548. Polygonscan shows the native balance. WETH is a different contract and is not the output.

Does this keep my ARB voting power?

Only on the amount you do not sell. Spent tokens leave the wallet. They are not bridged as ARB and they do not vote from Polygon. The credit is POL. Reduce the size if a proposal needs you. Chain id 42161, not Nova, is where unsold ARB remains.

What gas do I need on the source?

Native ETH on Arbitrum One. ARB cannot pay it, and POL cannot pay it before it exists on the destination. The sentinel on chain id 42161 is ETH. About 2 seconds is a Polygon block interval, not a free transaction on Arbitrum. Confirm the ARB contract on Arbiscan before you approve.
