There are multiple crypto exchange (Coin Swap) services that help you convert bitcoin. Most of these services are non-custodial and do not require signup.

How does Coin Swap work?

  1. Select 1 BTC, and the service will populate the amount of Eth you will receive based on the exchange rate (This exchange rate is approximate and varies for different services)
  2. Enter the Ethereum address in which you want to receive the ETh.
  3. Then the service will show you a Bitcoin address, send the exact amount of BTC to that address
  4. Enter your email for notifications (Optional)
  5. Always save the OrderId or TransactionId, in case something goes wrong
  6. Now wait for your coins
