BTC to ETH no KYC: swap Bitcoin and Ethereum both ways
NoxSwap Team
Yes, you can swap Bitcoin to Ethereum with no KYC: on NoxSwap there is no account, no e-mail and no documents. You pick BTC and ETH, see one guaranteed amount, send that exact BTC amount and receive ETH straight to your own wallet, and the same works the other way round. The one thing to get right is the Ethereum network, because the same 0x address exists on Ethereum, Arbitrum, Base and several other chains. Here is the whole process in both directions, how long it takes and what no KYC means in practice.
BTC to ETH, no KYC
Bitcoin to Ethereum in 3 steps
Typical times. The order page shows every step live.
- 1
Pick ETH and its network
Ethereum, Arbitrum, Base and more. Paste your 0x address and see the exact ETH that arrives.
No account, no KYC
- 2
Send the exact BTC
One payment with a normal fee, within the countdown on the order page.
About 10 minutes to send
- 3
Receive ETH
After the Bitcoin confirmation the ETH goes straight to your wallet on the network you chose.
Usually 10 to 60 minutes in total
Same 0x address on every chain: the network you pick decides where your ETH lands.
Swap BTC to ETHWhat you need for a no-KYC BTC to ETH swap
An Ethereum address in a wallet you control, the kind that starts with 0x. MetaMask, Rabby, a hardware wallet or any other self-custody wallet works. You also choose the network you want to receive ETH on: Ethereum itself, or a cheaper layer 2 such as Arbitrum, Base, Optimism, zkSync or Linea.
For the refund address, use a Bitcoin address from your own wallet. It is optional, but it is where your BTC goes back if the swap can't be completed, and an exchange deposit address is a poor choice for that. No account, no e-mail and no ID are needed for a swap.
Pick the right Ethereum network
A 0x address looks exactly the same on every Ethereum-compatible chain, so the address alone does not decide where your ETH lands. The network you pick in the widget does. ETH on Ethereum and ETH on Base are the same coin on different chains, and your wallet only shows the balance once it is switched to that chain.
If you plan to use the ETH in an app on a layer 2, receive it there directly and skip a bridge later. If you send it on to an exchange, check that the exchange supports deposits on that exact network first. Sending ETH on Base to an address that only watches Ethereum is a typical way to lose track of a payout.
BTC to ETH, step by step
Choose BTC as the coin you send and ETH on your network as the coin you receive, then type the amount of Bitcoin. The widget shows one number: the ETH that will arrive, with the exchange fee and network fees already included. Continue and paste your 0x address, and add a BTC refund address if you like.
Send exactly the displayed BTC amount within the countdown on the order page, typically about 10 minutes, in one payment and with a normal network fee. A different amount or a late deposit means the fixed quote no longer applies: the swap is recalculated at the market rate when the deposit arrives, or the BTC is refunded, and the order page shows which.
ETH to BTC: the other way round
Choose ETH on the network you actually hold it on as the coin you send and BTC as the coin you receive. Paste a Bitcoin address from your own wallet: one starting with bc1, 1 or 3 works. Lightning does not, because payouts go out on the regular Bitcoin network.
Send the exact ETH amount from that same network. Most wallets add the gas fee on top of the amount you type, so the quoted figure arrives; the max button takes the gas out of the amount instead. Withdrawing straight from an exchange? It deducts its withdrawal fee from the amount, so add that fee on top until the amount received matches the order.
How long it takes
BTC to ETH usually takes 10 to 60 minutes, and almost all of it is Bitcoin. A Bitcoin block comes about every 10 minutes on average, the exchange waits for confirmation, and a deposit with a low fee can wait longer when the network is busy. Once the swap runs, the ETH payout usually confirms within a minute or two.
ETH to BTC is usually quicker on the deposit side: an Ethereum deposit confirms within a few minutes. The BTC is then sent and shows as unconfirmed in your wallet until the next Bitcoin block. Plan on roughly 15 to 40 minutes in total. The order page shows every step live.
What no KYC means on NoxSwap
Swaps need no account, no e-mail and no documents, and NoxSwap never holds your coins. Each swap is executed by an established exchange at a fixed rate, and the payout goes straight to the address you entered.
No KYC does not mean no checks at all. The exchange executing a swap screens deposits for links to stolen or sanctioned funds, and large or flagged swaps can occasionally get an AML check. If that happens and you decline it, your deposit comes back without KYC, minus the network fee.
Frequently asked questions
Can I swap BTC to ETH without KYC? Yes. Swaps on NoxSwap need no account, no e-mail and no ID. Large or flagged swaps can occasionally get an AML check, and declining it gets your deposit refunded without KYC, minus the network fee.
Can I receive ETH on Base or Arbitrum? Yes. Pick ETH on that network in the widget. Your 0x address is the same, but the ETH arrives on the chain you chose.
Is there a minimum? NoxSwap has no minimum of its own. The exchange executing the swap has a small minimum for each pair, and the widget shows it only if your amount is below it.
Can I send BTC from an exchange? Yes, as long as the withdrawal leaves on the Bitcoin network, not Lightning, and the amount that arrives after the withdrawal fee is exactly the quoted one.
