Swap Ether to Bitcoin

No account, no email, no verification: measure a dose of Ether, paste the BTC address the distillate goes to, and the lab does the rest.

Both sides settle on their own chain: Ether needs a few blocks (1–3 min) before the lab sees the deposit, then Bitcoin is delivered within 1–2 confirmations (10–20 min).

The lab fee of 0.5% and the network fee for delivering BTC are both inside the quote; the only extra cost is what your own wallet charges to send ETH.

The process

How to swap ETH for BTC

  1. I

    Measure the ETH

    Enter how much Ether you pour and the BTC address the distillate goes to. The estimate updates before you commit.

  2. II

    Pour into the athanor

    Send exactly that dose from any wallet to the deposit address, on Ethereum mainnet. The furnace lights at the first confirmation (a few blocks (1–3 min)).

  3. III

    Collect the BTC

    The lab distills and delivers to your flask on Bitcoin mainnet. About 11 minutes end to end, confirmations included.

Questions

ETH → BTC, answered

More in the codex, or write to the lab.

How long does a ETH to BTC swap take?

About 11 minutes for the median batch. Most of it is waiting for a few blocks (1–3 min) on Ethereum; the delivery on Bitcoin is quick once distillation starts.

What is the minimum amount of ETH?

About 0.0091 ETH (about $20) at today's prices. Below that, network fees would eat the distillate, so the batch pauses until you top up or ask for a return.

Is the rate fixed?

Yes. The expected BTC output is engraved when you seal the batch and holds until the expiry shown on the deposit page. A deposit that arrives after expiry is handled at the live formula or returned, and you are told which.

Do I need an account or ID to swap ETH for BTC?

No. There is no account, no email and no identity check. The batch number you receive is the only way to find the batch again, so keep it.

Which BTC address should I give?

Any BTC address you control on Bitcoin mainnet, including an exchange deposit address. Double-check it: the lab cannot recall a distillate once it is sent.

What if I send ETH on the wrong network?

The deposit address listens on Ethereum mainnet only. Tokens sent on another chain are not seen by the athanor; some can be recovered by a technician for a handling fee, many cannot. When in doubt, send a small test dose first.
