Swap USDT from Ethereum to AVAX on Avalanche C-Chain
Swap USDT from Ethereum to AVAX on Avalanche C-Chain. A C-Chain wallet short of gas spends Ethereum Tether and receives native AVAX.
Native AVAX uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. That placeholder is the gas coin on chain id 43114, shown on Snowtrace as a native balance, not an X-Chain balance. The token you approve is Tether, 0xdAC17F958D2ee523a2206206994597C13D831ec7, on Etherscan. If your Tether is already the C-Chain contract at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7, swap it for AVAX there. This page starts from mainnet Tether and still needs ETH on chain id 1. Blocks there are about 12 seconds. Switch to the C-Chain to see the AVAX. Switch to the C-Chain and read the native AVAX line on Snowtrace. The X-Chain and the P-Chain will not show this balance. Confirm the native AVAX balance on Snowtrace after you switch the wallet to the C-Chain only.

Frequently asked questions
What is the best way to swap USDT from Ethereum to AVAX on Avalanche C-Chain?
Native AVAX uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. That placeholder is the gas coin on chain id 43114, shown on Snowtrace as a native balance, not an X-Chain balance.
I already hold USDT on the C-Chain. Should I use this page?
No. This page starts from Ethereum Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Etherscan. USDT at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 can be swapped for AVAX on the C-Chain. Using this bridge would move a mainnet balance you may be leaving in place on purpose. Confirm the full address on the explorer before you send it onward.
Is 0xEeee an AVAX contract on Snowtrace?
It is a placeholder for the native gas coin, not a contract to import. On chain id 43114 that coin is AVAX. Snowtrace shows it as the native balance. Importing the placeholder creates a useless row. The X-Chain is a different address system and is not this output.
What else belongs in the Ethereum wallet?
Tether plus ETH. The USDT contract cannot pay gas on chain id 1, and blocks there are about 12 seconds. AVAX does not exist on Ethereum yet, so it cannot pay the fee either. Add a small ETH balance before you approve 0xdAC17F958D2ee523a2206206994597C13D831ec7.
