Swap USDT from Polygon to USDC on Avalanche C-Chain

Swap USDT from Polygon to USDC on Avalanche C-Chain. Tether USDT leaves Polygon. Circle USDC is what can arrive on the C-Chain. The credit is native USDC, not the older USDC.e.

Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. USDC.e is 0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664 and is not this output. Polygonscan shows Tether. Snowtrace shows Circle on chain id 43114, not the X-Chain. Avalanche in this quote is the C-Chain only.

USDT leaves Polygon. USDC is what can arrive on Avalanche C-Chain.

Avalanche USDC.e is not this credit

If a pool wants 0xA7D7079b0FEaD91F3e65f86E8915Cb59c1a4C664, this route is wrong. It buys native USDC. The ticker will not save a wrong contract. Read Snowtrace.

You switch to Circle on the C-Chain

C-Chain USDT is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7. This page does not buy it. You switch from Tether to Circle. If the books must stay with Tether, choose the other output.

AVAX later, POL now

Neither stablecoin pays gas. POL on 137, AVAX on 43114. This quote includes neither spare fee balance. No finish time is stated for the bridge.

X-Chain wallets miss this USDC

An X-Chain wallet will not list this USDC. Chain id 43114 is the EVM C-Chain. Snowtrace is the explorer that can show the contract.

Frequently asked questions

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

Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. XAUConnect compares live routes and lets your own wallet sign.

Is the arriving USDC the bridged 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 Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Snowtrace is the check. The X-Chain will not show it. The ticker alone will lie. Match the native USDC contract character for character, not USDC.e.

Why is AVAX required if I only hold USDC?

Because USDC is not gas on the C-Chain. AVAX is. This route does not buy AVAX or WAVAX. Keep some AVAX on chain id 43114 if you need to move the USDC after Snowtrace shows it. POL was only the Polygon fee. There is no bridge finish time here.

Can I keep Tether instead?

Not on this page. C-Chain Tether is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7. Circle and Tether are different issuers. Switch outputs before you approve the Polygon USDT. Polygonscan should show 0xc2132D05D31c914a87C6611C10748AEb04B58e8F, not an Ethereum contract. Tether on Polygon and Circle on the C-Chain are different issuers, so switch if the form says Tether.
