Swap AVAX from Avalanche C-Chain to USDT on Ethereum

Swap AVAX from Avalanche C-Chain to USDT on Ethereum. Native AVAX leaves the C-Chain, and Tether USDT arrives on Ethereum.

Sell C-Chain AVAX, chain 43114, placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Snowtrace shows the account. Keep a fee remainder. No approval applies to native AVAX. The C-Chain is not the X-Chain. Receive Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum, chain 1, on Etherscan. It uses 6 decimals. It is not Circle USDC. Blocks are about 12 seconds. USDT cannot pay Ethereum gas, so you need ETH on mainnet from somewhere else. C-Chain Tether at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 is not the output.

Diagram for Swap AVAX from Avalanche C-Chain to USDT on Ethereum
AVAX leaves Avalanche C-Chain. USDT is what can arrive on Ethereum.

Tether on mainnet, not the C-Chain copy

People who already hold 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 sometimes think this route moves that token. It does not. It sells AVAX and buys Ethereum Tether. The contracts differ. Tether can freeze addresses on the destination contract. Selling AVAX does not change a freeze that already applies to you.

Leave AVAX for the broadcast

The coin you sell is the coin that pays the C-Chain fee. Drain it and the transaction never starts. There is no ERC-20 approval. If the balance is on the X-Chain, switch to the C-Chain before you look at this quote. You will not hold AVAX on Ethereum when the trade completes.

Mainnet still wants ETH

USDT is an old ERC-20 and cannot pay gas. Blocks on chain 1 are about 12 seconds when you do have ETH. Trade on Ethereum is that fee environment. Snowtrace will show AVAX leaving. Etherscan will show USDT arriving. No shared hash, and no promised wait.

Dollar choice

Circle's contract is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. DAI is Maker's. If either of those was named, leave. If you wanted WETH or native ETH, leave. If the minimum USDT is a bad sale of AVAX, leave the quote unsigned. Chain 1 blocks take about 12 seconds and do not time this bridge.

Frequently asked questions

What is the best way to swap AVAX from Avalanche C-Chain to USDT on Ethereum?

Sell C-Chain AVAX, chain 43114, placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Snowtrace shows the account. XAUConnect compares live routes and lets your own wallet sign.

Is this the USDT I already hold on Avalanche?

No. Avalanche Tether is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7. This route sells native AVAX and delivers Ethereum Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7, which you check on Etherscan. The source network is the C-Chain, chain 43114, on Snowtrace, not the X-Chain. The two Tether contracts are not interchangeable, even when the ticker matches.

Do I approve AVAX?

No. The placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is the gas coin, and you send it. Leave enough AVAX on chain 43114 for the fee. An approval request means a token is selected. Recheck the asset. This page does not pull USDT or USDC as the input. Native AVAX is not an ERC-20.

Can the USDT I receive pay mainnet fees?

No. Ethereum gas is ETH. USDT cannot pay it, and the AVAX you sold does not reappear as ETH. Blocks are about 12 seconds only after you have ETH to spend. Fund that ETH or the Tether balance on Etherscan cannot be moved. AVAX on the C-Chain is a separate coin.
