BTC TO ETH WALKTHROUGH

How to swap Bitcoin to Ethereum from a self-custody wallet

Reviewed September 1, 2026 · Swapario editorial

SHORT ANSWER

A native BTC-to-ETH swap takes a Bitcoin-mainnet deposit and pays native ETH to an Ethereum-mainnet address. It is an exchange between two networks, not a direct bridge transaction. Confirm a BTC deposit address, an Ethereum 0x payout address and the live estimate before sending.

01

Choose native BTC and native ETH

The source should say Bitcoin mainnet and the destination should say Ethereum mainnet. Wrapped Bitcoin, Lightning and ETH on a layer-2 network are separate routes even when the economic asset looks similar.

02

Use a Bitcoin refund address and Ethereum destination

The ETH destination normally begins with 0x. The refund address must accept native BTC. Copy both from their respective wallets and never infer a network only from a ticker.

  • Destination: ETH on Ethereum mainnet
  • Refund: BTC on Bitcoin mainnet
  • Deposit: the new address generated for this order

03

Allow for Bitcoin confirmations and provider processing

The wallet can show a broadcast before the provider considers the deposit confirmed. Total duration includes deposit detection, Bitcoin confirmations, conversion and the Ethereum payout.

CONCRETE EXAMPLE

Example: why native BTC and a 0x address belong on opposite sides

For a 0.05 BTC exchange, the generated deposit belongs to Bitcoin and may begin with bc1. The payout destination belongs to Ethereum and begins with 0x. The user sends BTC from the Bitcoin wallet to the generated Bitcoin deposit; the provider later sends ETH to the 0x destination. A bridge would instead work with a token representation such as wrapped BTC on a smart-contract network. Treating those flows as interchangeable can produce a wrong-network transfer, so both sides must remain visible during the entire order.

CHECK THIS CASE

  1. 1Use a Bitcoin refund address, not the Ethereum payout address.
  2. 2Wait for the tracker to report deposit detection and required confirmations.
  3. 3Use the payout transaction hash to verify the final Ethereum transfer.

ACTION CHECKLIST

Before you continue

  • Use Bitcoin mainnet, not Lightning or wrapped BTC.
  • Use an Ethereum-mainnet 0x destination.
  • Review the estimated ETH output before continuing.
  • Send only once to the generated BTC deposit address.
  • Track the payout with the private order link.

FAQ

Questions about this topic

Is swapping BTC to ETH the same as bridging?+

No. A bridge usually moves a representation between compatible smart-contract networks. A BTC-to-ETH exchange converts between native Bitcoin and native Ethereum.

Can I receive ETH on Base instead?+

Only by selecting an ETH-on-Base payout route. An Ethereum-mainnet page and Base payout are not interchangeable.

Why has my BTC deposit not started exchanging yet?+

It may still be waiting for detection or the required Bitcoin confirmations. Check the private tracker before taking another action.
