How to Swap BTC to ETH — Convert Bitcoin to Ethereum, No Account

Updated June 2026 · ~4 min read

You hold Bitcoin and you want Ethereum — to use DeFi, mint, pay gas, or just rebalance. You don't need a centralized exchange, an account, or a KYC check. Here's the fast, no-KYC way to convert BTC to ETH cross-chain, in three steps.

⚠️ One thing to get right: Bitcoin and Ethereum are separate blockchains. You can't "send" BTC to an Ethereum address — you convert across chains. A cross-chain swap does exactly that: you send BTC, you receive ETH at your Ethereum address.

Swap BTC to ETH in 3 steps

Choose the pair
Select BTC as what you send and ETH as what you receive, then enter the amount. Open the BTC → ETH swap →
Enter your Ethereum wallet
Paste the Ethereum-network address where you want your ETH. No account or email needed.
Send and receive
Send your BTC to the one-time deposit address. After Bitcoin confirmations, the swap delivers ETH to your wallet — usually within minutes.

What it actually costs

The headline "fee" is only half the story. Your real cost on any BTC → ETH conversion is the fee plus the spread (the gap between the quoted rate and the market rate). The honest way to compare services: look at the ETH amount you actually receive for the same BTC input. A flat, visible fee with a fair rate usually beats a "0% fee" quote hiding a wide spread, and it always beats a CEX that charges deposit + withdrawal fees and forces KYC.
