Swap USDT from Polygon to AVAX on Avalanche C-Chain
Swap USDT from Polygon to AVAX on Avalanche C-Chain. Tether USDT leaves Polygon. Native AVAX is what can arrive on the C-Chain. You sell a dollar token for the gas coin on chain id 43114.
Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On this destination that label is AVAX, not WAVAX at 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7. Polygonscan shows Tether. Snowtrace shows AVAX. Not the X-Chain. How to bridge assets between chains covers the separate gas balances.

C-Chain AVAX is not an allowance
X-Chain is not the credit
The C-Chain output is AVAX, not USDT
Tether cannot pay Polygon

Frequently asked questions
What is the best way to swap USDT from Polygon to AVAX on Avalanche C-Chain?
Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. XAUConnect compares live routes and lets your own wallet sign.
Is C-Chain AVAX the same as X-Chain AVAX?
No. This credit is native AVAX on the C-Chain, chain id 43114, marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Snowtrace shows it. The X-Chain will not. You sold Polygon Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. WAVAX at 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7 is a different asset. Do not approve the gas label. Native AVAX has no bytecode to approve on Snowtrace.
Will I receive WAVAX if pools prefer it?
Not from this quote. WAVAX is the wrapped contract. This route pays native AVAX, which can pay gas. Sign here only if native gas is what you want. Wrapping afterward spends a little of that AVAX. Snowtrace should show a native balance first, on the C-Chain only.
What if the AVAX floor looks poor?
Do not sign it. USDT against AVAX can move. Request a new quote. No finish time is given for the bridge. About 2 seconds is only Polygon. The destination is Avalanche C-Chain, chain id 43114, not the X-Chain and not Ethereum. Refresh the quote if that AVAX floor looks too weak.
