Why swap BTC to ETH?
Rotating between assets? Swapping Bitcoin (BTC) for Ethereum (ETH) rebalances your exposure directly — no stablecoin round-trip and no centralized exchange account. Atomic Exchange moves you from Bitcoin to Ethereum non-custodially, so you keep control of your keys the entire time.
About the assets
Bitcoin is the original cryptocurrency and the largest by market cap — a decentralized, fixed-supply asset often called digital gold.
Ethereum is the leading smart-contract platform; its native token ETH powers transactions, DeFi and NFTs across the Ethereum ecosystem.
How the swap works
- Enter the amount. Choose how much Bitcoin you want to swap to Ethereum; the quote updates before you commit.
- Sign in with a passkey. Your email plus Face ID or Touch ID — no seed phrase, no browser extension, no wallet app to install.
- Confirm gaslessly. Atomic executes the BTC→ETH swap without you holding a native gas token.
- Stay in control. The swap is non-custodial end to end — your keys, and the Ethereum lands in your account.

Trading this pair at size?
Atomic runs a flash loan desk for professional counterparties: uncollateralised BTC and ETH liquidity, borrowed and repaid inside a single transaction. No collateral, and no outstanding balance — if the transaction does not repay, it reverts and never happened. The fee is a share of profit, so a trade that does not profit costs nothing but gas.
