Swap WBTC from Ethereum to AVAX on Avalanche C-Chain

Swap WBTC from Ethereum to AVAX on Avalanche C-Chain. You send WBTC on Ethereum and you receive native AVAX on Avalanche C-Chain.

WBTC is the ERC-20 at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599, which you confirm and approve on Etherscan. It is not a coin on the Bitcoin chain. Ethereum, chain id 1, charges ETH for gas and blocks in about 12 seconds. The AVAX you receive is the C-Chain gas coin, marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, and Snowtrace is where that native credit belongs. Chain id 43114. The X-Chain is not involved.

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

An Ethereum token with eight decimals

Approve only 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599. Other tokens that mention bitcoin in the name are not this input. You need ETH beside the WBTC or the approval cannot be mined. A Bitcoin address cannot be the source and cannot be the destination. If that is the address you were given, leave this page.

AVAX arrives as the native coin

The output marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means native AVAX on C-Chain, not a wrapped token and not USDC. Snowtrace will show a native transfer rather than an ERC-20 payout. That AVAX can pay later C-Chain fees. It is still the wrong network if you are watching the X-Chain. Ethereum ETH does not become spendable gas on Avalanche.

Do not use this for dollars or for Bitcoin

Tether and Circle USDC are different routes with token contracts, not the gas-coin marker. A payment on the Bitcoin chain is outside this product. If you wanted to keep bitcoin exposure, selling WBTC into AVAX is the wrong tool because you take AVAX price risk while the bridge is open. C-Chain basics help if the chain names are blurring. No price is locked.

Two volatile prices and an ETH fee

You are leaving WBTC and arriving in AVAX. Both can move, so the quote's AVAX estimate is not a floor. The minimum AVAX is the floor, and you should sign only if you would still accept it. ETH gas on Ethereum is an extra cost on top. Block time near 12 seconds is not a delivery promise. Confirm the wallet says chain id 1 before the signature.

Frequently asked questions

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

WBTC is the ERC-20 at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599, which you confirm and approve on Etherscan. It is not a coin on the Bitcoin chain.

Does the AVAX side use a token contract I can open?

The destination is the native marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means AVAX, the gas coin, on C-Chain. It is not an ERC-20 page on Snowtrace. The input is a real contract, WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599, and that one does open on Etherscan. You approve the input only.

Will this send bitcoin to an Avalanche X-Chain address?

No. It spends WBTC on Ethereum and delivers native AVAX on C-Chain, chain id 43114. X-Chain addresses are the wrong tool for this route. The Bitcoin network is not a hop in the middle. If Snowtrace is not the explorer you are checking, you are on the wrong screen.

What happens if AVAX falls after I sign?

The site cannot reverse a confirmed Ethereum transaction, and it does not insure the AVAX price. That is why the minimum on the quote matters before you sign. If you need a dollar token instead of AVAX, use the USDC or USDT page. Gas for the send is still ETH.
