Swap USDT from Arbitrum One to AVAX on Avalanche C-Chain

Swap USDT from Arbitrum One to AVAX on Avalanche C-Chain. Tether USDT leaves Arbitrum One and native AVAX arrives on C-Chain.

Sell 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Arbiscan, chain id 42161, not Nova. Keep ETH for gas. Receive native AVAX, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on C-Chain chain id 43114. Snowtrace shows the balance. It is not WAVAX, not the X-Chain, and not a stablecoin. Blocks are about 2 seconds. Do not treat that as the route's deadline.

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

Buy the gas coin, not the wrapped one

C-Chain fees come from native AVAX. This sentinel output can pay them. WAVAX cannot, until someone wraps and then unwraps, which is a detour this page skips. If a contract insists on the WAVAX address, you are on the wrong route and would still need AVAX to wrap. Snowtrace will not show a token page for the sentinel.

Tether does not lock an AVAX price

USDT targets a dollar. AVAX floats. The minimum expires with the quote. Six decimals in, eighteen out. Read whole tokens. How to bridge assets between chains does not freeze that cross rate. If you step away to check Snowtrace, refresh before you sign.

Address type is part of the route

The receiver must be a C-Chain address, chain id 43114. X-Chain strings are the wrong destination even when the ticker says AVAX. P-Chain is wrong too. The source approval, if any, is Tether on Arbitrum One, paid in ETH. AVAX cannot pay it in advance.

Wrong if dollars should remain dollars

C-Chain USDT and Circle USDC are other pages. WAVAX is another page. The X-Chain is another network. Nova is the wrong source. This quote is only for native C-Chain AVAX. Before you sign, compare 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 with 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on their explorers and stop if either address on the quote differs. If the quote expires, request another and read the new minimum before you sign. Sign only on the source chain id named in this article, with the wallet network checked.

Frequently asked questions

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

Sell 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.

Is native AVAX the same as WAVAX?

No. This route credits the gas coin, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on C-Chain chain id 43114. WAVAX is a separate ERC-20. You spend Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Snowtrace shows AVAX as a balance. If a pool wants WAVAX, wrap after you have gas, or pick a different output.

Can the credit go to the X-Chain?

No. X-Chain and P-Chain are not chain id 43114. This page is C-Chain only. An exchange deposit that specifies the X-Chain will not match this balance. About 2 seconds is a C-Chain block interval, not an invitation to use another Avalanche chain. Confirm the address on the explorer before you sign.

What do I need on Arbitrum first?

Tether at the address above, plus native ETH for gas on chain id 42161, not Nova. AVAX arrives later and cannot pay the source fee. If the quote expires, request a new minimum, because AVAX's price against USDT moves. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
