Swap WETH from Polygon to USDC on Avalanche C-Chain
Swap WETH from Polygon to USDC on Avalanche C-Chain. Polygon WETH leaves Polygon. Native Circle USDC is what can arrive on the C-Chain. USDC.e is not the credit, and a local unwrap does not create it.
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. USDC.e is 0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664. Polygonscan shows WETH. Snowtrace shows native USDC on chain id 43114. Not the X-Chain. POL pays the source. AVAX pays later moves. Avalanche means that C-Chain credit.
Avalanche USDC.e is not the WETH route's credit
Polygon WETH is not WAVAX
POL now, AVAX later
Polygon cannot unwrap into C-Chain USDC

Frequently asked questions
What is the best way to swap WETH from Polygon to USDC on Avalanche C-Chain?
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. XAUConnect compares live routes and lets your own wallet sign.
Is the credit USDC.e?
No. USDC.e on Avalanche is 0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664. This route buys native Circle USDC at 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E on the C-Chain, chain id 43114. You sell Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Snowtrace is the check. The X-Chain will not show it. The ticker is not enough. Read the full native USDC address on Snowtrace before you deposit.
Does this USDC pay C-Chain gas?
No. Gas is AVAX, not USDC. This quote does not buy AVAX or WAVAX. Keep AVAX on chain id 43114 or the USDC waits. There is no finish time for the bridge. Polygon still charges POL to send the WETH. Snowtrace will not show a gas stipend.
What if I hold POL and call it WETH?
POL is the native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, not the WETH contract. This page cannot spend POL as the principal. If WETH is missing, use a POL quote. Keep POL anyway, because chain id 137 takes it as the fee. The destination remains the C-Chain. X-Chain explorers will not list this USDC credit.
