Short answer: yes, you can swap ETH on Ethereum straight into native BTC on the Bitcoin network, without wrapping anything yourself. The best way is to compare several cross-chain routes for your exact amount and pick on the BTC you actually receive, not on the lowest fee and not on the "1 BTC = X ETH" rate at the top of the screen. I tested this twice on Rango with 0.5 ETH, and the gap between the best and worst route was about $27 to $28 both times.
Links I used, in order: Rango's ETH to BTC page, Rango's guide on how to swap crypto with Rango, Rango's bridge vs swap explainer, and the official docs of three route providers: TeleSwap, Chainflip and Relay.
Native BTC or wrapped BTC?
This is the first thing to get right. "BTC" on Ethereum is usually a wrapped token like WBTC: a token that tracks Bitcoin's price but lives on Ethereum. Native BTC lives on the Bitcoin chain, at a Bitcoin address (the ones that start with bc1, 1 or 3).
If you want BTC in a Bitcoin wallet, a hardware wallet, or an exchange deposit address on the Bitcoin network, you need native BTC. A plain swap on Ethereum gives you wrapped BTC. Rango's bridge vs swap page puts it simply: a bridge moves the same asset to another network, a swap changes the asset. ETH to native BTC changes both the asset and the network in one go.
Every route in my tests below delivered native BTC on the Bitcoin network. That is what "To: BTC, Bitcoin" means in the Rango app.
How I tested
I opened the Rango app, set From: ETH on Ethereum, To: BTC on Bitcoin, amount 0.5 ETH, slippage 1%, Smart Routing. I did not connect a wallet or send anything, so these are live quotes, not finished swaps. I ran it twice, about seven hours apart, and wrote down every route shown.
Test 1: Thursday 8 October 2026, 5:53 PM WAT (16:53 UTC). 0.5 ETH was about $1,217.
Test 2: Friday 9 October 2026, 1:03 AM WAT (00:03 UTC). 0.5 ETH was about $1,236.59, and the app showed 1 BTC = 32.99 ETH (about $81,582.60).

What is the cheapest way to swap ETH to BTC?
Measure "cheapest" by the BTC that lands in your wallet. In both tests the route tagged Lowest Fee paid out the least BTC.
In test 2, XO Swap had $0.00 gas but gave 0.014825 BTC. TeleSwap charged $0.06 gas and gave 0.015157 BTC. That is 33,200 sats more, about $27 at the app's rate. In test 1 the gap between the top and bottom route was 34,200 sats, about $28. The fee line is only one part of the cost. The rate each route gets, its liquidity and slippage matter more.
The rate at the top of the screen is not your payout either. At 1 BTC = 32.99 ETH, 0.5 ETH works out to about 0.015156 BTC. The best route came very close to that. The app also shows each route's payout against the dollar value of your 0.5 ETH: TeleSwap was slightly above it, XO Swap was 2.04% under it.
Cheapest vs fastest
The fastest route was not the one that paid the most. In test 2 Flashnet was tagged Fastest at about 45 seconds and gave 7,300 sats less than TeleSwap (about $5.96), while TeleSwap was estimated at 22 minutes. In test 1 Relay was fastest at about 30 seconds and gave 11,900 sats less than TeleSwap (about $9.68).
So the trade is real: on 0.5 ETH, roughly $6 to $10 bought about 21 minutes. If you need the BTC quickly, that may be worth it. If not, waiting pays. Harbor and BOB Gateway sat in between: close to the top payout, done in under 3 minutes.
The route list also changed between my two tests. Relay was the fastest route on Thursday evening; by early Friday Flashnet held that tag, and gas costs had dropped sharply. Quotes move with the market and with which providers have liquidity, so check right before you swap.
Why the routes differ
Each route uses a different design to get from Ethereum to the Bitcoin chain:
-
TeleSwap uses "Lockers" that hold BTC, with Bitcoin transactions checked by a light client running on the other chain, per its protocol overview. Its estimate was the slowest of the six.
-
Chainflip runs its own validator network and an AMM on its "State Chain" that swaps native assets between chains, per its docs on how swapping works.
-
Relay uses solvers who front the funds on the destination chain and get repaid, per its cross-chain swaps docs, which is why it can be very fast.
A cross-chain aggregator like Rango puts these side by side so you don't have to check each one by hand.
How to swap ETH to native BTC, step by step
-
Open Rango's ETH to BTC page or the Rango app.
-
Set From: ETH on Ethereum and To: BTC on Bitcoin. Check that the destination network says Bitcoin if you want native BTC.
-
Enter your amount. Results change with size, so quote the real amount you plan to swap.
-
Compare the route cards on BTC received first, then estimated time, then gas.
-
Connect your Ethereum wallet and add the Bitcoin address you want to receive to. Double check it. A wrong Bitcoin address can't be reversed.
-
Review slippage (1% was the default in my tests), confirm, and track the swap until the BTC arrives.
My take
The best way to swap ETH to BTC is to compare routes on the payout for your exact amount, decide how much speed is worth to you, and make sure you are receiving native BTC if that's what you need. In my two tests TeleSwap paid the most BTC both times but was the slowest, and the lowest-fee route paid the least both times. Those are two snapshots, not a rule. Run your own quote before you swap.
Rango has had zero exploits since August 2021 and routes across 80+ chains. For live volume and swap stats, see the Rango explorer.
