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

Swap BNB from BNB Chain to AVAX on Avalanche C-Chain. Native BNB leaves the wallet on BNB Chain. Native AVAX is what can arrive on Avalanche C-Chain. The coin that pays gas changes with the network.

Both sides quote 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, a label for the native coin rather than a contract with code. Chain id 56 confirms in about 3 seconds on BscScan. Chain id 43114 is the C-Chain, and the credit belongs on Snowtrace. The X-Chain stays empty. How cross-chain bridges work covers why these two balances never merge.

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

Fee and principal share one BNB balance

The network fee and the amount you sell both come out of BNB. Sending every last unit leaves chain 56 unpaid. Keep a remainder. This quote never spends WBNB at 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c.

WAVAX is a different receive

Native AVAX can pay later C-Chain fees. The wrapped token at 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7 will not appear from this quote. If a pool asked for WAVAX, this output is the wrong one.

Two explorers, two coins

BscScan records BNB leaving chain 56. Snowtrace records AVAX on the C-Chain only. The placeholder text matches and the assets do not. Match the signing wallet and the full address, not a shortened prefix.

Price can move before you sign

BNB against AVAX can reprice while the quote sits open. Take the minimum shown or request a fresh quote. No finish time is stated for the bridge leg. A dollar output on Avalanche is a different route.

Frequently asked questions

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

Both sides quote 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, a label for the native coin rather than a contract with code. Chain id 56 confirms in about 3 seconds on BscScan.

Why is the address the same on both chains?

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE marks native gas, and each chain defines its own. On BNB Chain, chain id 56, it is BNB. On Avalanche C-Chain, chain id 43114, it is AVAX. There is no approval for that label. BscScan shows the debit and Snowtrace shows the C-Chain credit.

I hold WBNB. Will this quote spend it?

No. WBNB is the BEP-20 at 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c. This page spends native BNB only. If the balance you mean is WBNB, you are on the wrong route. Unwrap on BNB Chain or open a quote that names the WBNB contract. BscScan will show that contract, not a native debit.

Must I already hold AVAX to receive it?

You need BNB on chain 56 for the sale and for gas. A prior AVAX balance is not required for the credit to be created. The receive address must be a C-Chain address. X-Chain AVAX is a different system and will not show this credit.
