Swap AVAX from Avalanche C-Chain to USDT on BNB Chain

Swap AVAX from Avalanche C-Chain to USDT on BNB Chain. Native AVAX leaves the C-Chain, and 18 decimal USDT arrives on BNB Chain.

Sell AVAX on chain 43114, placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Snowtrace shows the account. Keep a fee remainder. No approval on the gas coin. The C-Chain is not the X-Chain. Receive 0x55d398326f99059fF775485246999027B3197955 on chain 56. BscScan should show 18 decimals. That is not Ethereum Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7, which uses 6. Blocks are about 3 seconds. BNB, not USDT, pays the next fee. C-Chain Tether at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 is not the output, because you are selling AVAX, not that token.

The decimal trap, again, from a gas coin

You are not moving C-Chain USDT. You are selling AVAX into an 18 decimal dollar on BNB Chain. A decoder built for 6 decimal Tether will mis-state the credit by a huge factor. Read BscScan's decimals field. The human amount on the quote is the figure to accept or reject. AVAX price, not a one-dollar identity, drives the size.

Remainder on the C-Chain

Leave AVAX for the fee. The X-Chain does not count. There is nothing to approve. You will not hold AVAX on BNB Chain afterward. If the wallet shows an approval for a token, you selected USDT or USDC by mistake and should back out.

BNB, then the dollars can move

USDT cannot pay chain 56. Trade on BNB Chain states that BNB is mandatory. Three second blocks are not the bridge wait. Snowtrace and BscScan will not share a hash. If the minimum USDT is a poor sale of AVAX, do not sign. The 18 decimal width is the detail a 6 decimal habit will miss on BscScan.

Contracts people paste by habit

Ethereum USDT, C-Chain USDT, and this 18 decimal token are three addresses. Pegged USDC is a fourth. Pegged ETH is a fifth. Only 0x55d398326f99059fF775485246999027B3197955 is the arrival. Open that one on BscScan.

Frequently asked questions

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

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

Is this the USDT already on Avalanche?

No. Avalanche Tether is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7. This route sells native AVAX and delivers 0x55d398326f99059fF775485246999027B3197955 on BNB Chain, 18 decimals, on BscScan. Ethereum Tether uses 6 decimals and a different address. The source chain is 43114, the C-Chain, not the X-Chain. Eighteen decimals separate this credit from Ethereum Tether.

Do I approve AVAX before selling it?

No. The gas coin is sent, not approved. The placeholder is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Leave enough AVAX on chain 43114 to pay the fee. An approval popup means another asset is selected. This page will not pull a USDT balance as the input. Only native AVAX is sold here.

Will the USDT pay fees on arrival?

No. BNB pays chain 56. USDT cannot. Blocks are about 3 seconds when that BNB is present. AVAX does not convert into BNB. Fund the gas coin or the 18 decimal balance is visible on BscScan and stuck. BNB has to be added before the token can transfer.
