Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One. Arbiscan, chain id 42161, not Nova. Source gas is ETH. Receive native POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137. That marker is the gas coin, not WETH and not ETH. Polygonscan shows a POL balance, not an ERC-20 supply. Blocks are about 2 seconds. The bridge is not tied to that clock. Older wallets may still say MATIC for this same native balance.
POL replaced the gas ticker people still say aloud

Frequently asked questions
What is the best way to swap USDC from Arbitrum One to POL on Polygon?
Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One. Arbiscan, chain id 42161, not Nova.
Is the 0xEeee output ETH or POL?
POL. On Polygon, chain id 137, the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is the native gas coin. It is not ETH and not WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Polygonscan shows POL as a balance. A wallet label of MATIC usually means this same native coin.
Do I approve POL to receive it?
No. Native POL is not an ERC-20 receive approval. Any approval is for Circle USDC on Arbitrum One, paid in ETH, chain id 42161, not Nova. About 2 seconds is a Polygon block interval. It is not a promise that POL has arrived, and it does not replace the source ETH fee.
Will this POL balance be a stablecoin?
No. You are selling Circle USDC, which targets a dollar, for POL, which does not. Use the minimum on the quote. If you needed USDT or native Circle USDC on Polygon, this sentinel output is the wrong asset. The price can move until you sign, and an expired quote takes the minimum with it.
