Swap ETH from Arbitrum One to POL on Polygon

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

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE and they are different coins. On Arbitrum One, chain id 42161, it is ETH, which you sell and which also pays the fee. Arbiscan, not Nova. On Polygon, chain id 137, it is POL, the gas coin. Polygonscan shows a balance. It is not WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Blocks are about 2 seconds. That is not a bridge timer. Wallets may still say MATIC.

Read the chain id beside the sentinel

The hex does not identify the coin. Chain id 42161 means ETH. Chain id 137 means POL. This route sells one gas coin for the other. It does not move ETH onto Polygon as ETH, because Polygon does not use ETH as gas. If you needed the WETH contract, the sentinel output is the wrong shape. If a form asks you to paste 0xEeee as a token contract, decline. It is a marker.

Leave source gas, gain destination gas

You must not sell the last ETH, or the signature fails. The POL you receive can pay later fees on Polygon, which is the practical reason to choose this pair. It arrives too late to pay Arbitrum. WETH on Arbitrum is not the balance being sold. If that is all you hold, wrap status matters: unwrap first, reserve a fee, then use this page, or pick the WETH route instead.

Two prices, no redemption rate

ETH and POL both float. The minimum POL is the number to accept or reject. It expires. Eighteen decimals on both do not mean equal amounts. How cross-chain bridges work explains the hop between chain ids. It does not publish a fixed ETH to POL rate.

Wrong when the ETH ticker must remain

Anyone who needs Polygon WETH, Circle USDC, or Tether is on the wrong page. Anyone on Nova is on the wrong network. Anyone who thinks a MATIC-labeled balance is a different asset from POL should still treat the native row as the output, not hunt a second contract. Anyone who wanted Ethereum mainnet ETH is on the wrong destination chain.

Frequently asked questions

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

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE and they are different coins. On Arbitrum One, chain id 42161, it is ETH, which you sell and which also pays the fee.

If both addresses are 0xEeee, do I receive ETH on Polygon?

No. On Polygon the sentinel is POL, the gas coin of chain id 137. ETH is the sentinel only on Arbitrum One, chain id 42161, where you spend it. WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 is not this output. Polygonscan shows POL as a balance. A MATIC label usually means that same native coin.

Should I keep ETH on Arbitrum?

Yes, enough for the fee. You are selling the fee coin, so the full balance cannot go. WETH will not pay that fee. Nova is not the source. POL that arrives later is useful on chain id 137 only. About 2 seconds is a Polygon block interval, not a reason to spend the last wei.

Is POL a stablecoin on this route?

No. You are swapping two volatile gas coins. Read the minimum POL and refresh the quote if it lapses. If you wanted Circle USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 or Polygon USDT, this sentinel output is the wrong asset. Neither dollar contract is implied by the word swap.
