Swap POL from Polygon to USDC on Avalanche C-Chain

Swap POL from Polygon to USDC on Avalanche C-Chain. Native POL leaves Polygon. Circle USDC is what can arrive on the C-Chain. You spend the gas coin, then hold a dollar token that cannot pay C-Chain fees.

The source is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. The output is 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E, native USDC, not USDC.e. Polygonscan shows a native debit. Snowtrace shows Circle. Leave POL for the fee. You still need AVAX later. Not the X-Chain. Polygon is where that POL has to sit.

Save POL before the C-Chain USDC hop

Fee and principal share one coin. About 2 second blocks are not the bridge. Wrapped POL at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 is not this quote. If that is the balance, stop.

C-Chain USDC.e is not this POL credit

0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664 will not arrive. Native USDC will. A form that names the bridged contract will miss this deposit. Tether would be another route.

AVAX is still required later

USDC cannot pay chain id 43114. This route does not buy AVAX. A new C-Chain wallet can hold USDC and fail the next transfer. The X-Chain will not show the token.

POL has no allowance on the way to Avalanche

Polygonscan should show a native POL debit. An allowance popup for 0xEeee means you left the route. The USDC credit is only on Snowtrace.

Frequently asked questions

What is the best way to swap POL from Polygon to USDC on Avalanche C-Chain?

The source is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. The output is 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E, native USDC, not USDC.

Do I approve the POL label?

No. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native POL on chain id 137. Polygonscan should show a native debit. The USDC you can receive is 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E on Snowtrace, C-Chain chain id 43114. Approving the gas label is the wrong action. Keep some POL for the fee. The X-Chain is not this credit.

Is this USDC the bridged kind?

No. USDC.e is 0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664. This credit is native Circle USDC. If a pool named the bridged contract, this route is wrong. Snowtrace shows which contract arrived. The ticker alone is not the check. Stay on the C-Chain. USDC.e is a different Avalanche contract, so read the full address.

Does the USDC arrive with AVAX?

No. AVAX is a separate coin on chain id 43114. This quote pays USDC only. WAVAX is not included either. Fund AVAX yourself if you need to move the dollars. There is no finish time stated for the bridge. POL paid only the Polygon side.
