Live rates

Instantly swap BTC to ETH at a live market rate

Compare your estimated payout in real time, lock your route, and complete the exchange directly wallet-to-wallet in minutes.

Comparison overview

No-KYC instant exchanges bridge assets across chains with a simple send-and-receive UX. DEXs swap within connected wallet ecosystems on-chain. CEXs hold custody and offer order books, fiat ramps, and usually KYC.

Custody differences

Instant swaps and DEX trades are non-custodial during the swap—you send from your wallet. CEXs hold balances on your behalf.

Fees compared

DEXs charge gas plus pool fees. CEXs charge trading fees but may subsidize withdrawals. Instant swaps bundle spread and service fees—compare total received on BTC to ETH.

Speed and UX

CEX order books are fast once funded—but funding requires deposits and KYC. Instant swaps skip accounts. DEXs need gas tokens on each chain.

Privacy

No-KYC instant swaps minimize profile data. CEXs link activity to identity. DEXs are pseudonymous on-chain but public.

When each wins

Use instant exchanges for quick cross-chain wallet swaps. Use DEXs for on-chain DeFi within one ecosystem. Use CEXs for fiat and deep liquidity if you accept KYC.

best no-KYC picks, what is KYC, cross-chain mechanics.

Instant swaps like BTC to USDT illustrate how wallet-first conversion differs from custodial trading. You send once and receive to an address you specify—no order book or account balance.

Always verify you are on the official SwapFellow domain before entering addresses or sending funds. Phishing clones are the most common threat in instant exchange workflows.

Network selection often matters more than small rate differences. A slightly better rate on the wrong USDT network can cost more in recovery time than the savings.

Keep a simple checklist: correct asset, correct network, correct address, correct amount, memo/tag if required, quote still valid. That checklist prevents most user-side failures.

SwapFellow is built for practical, wallet-first conversion without unnecessary data collection. Compare quotes, read the guides above, and move funds on the network your wallet actually supports.

TL;DR

Send BTC to a one-time address and receive ETH after required confirmations.
Rates and estimated payout are visible before sending.

What you will need

How to convert BTC to ETH

Open the swap widget and select BTC to ETH.
Paste your receiving wallet address and choose fixed or floating rate.
Review quote details, including expected output and network costs.
Send the exact amount to the generated one-time deposit address.
Track confirmations and receive ETH directly in your wallet when completed.

Fees, confirmations, and timing

Total cost depends on network conditions, quote type, and transfer amount. For best results, send the exact quoted amount inside the quote window and confirm you are on the correct source network for BTC.

In practice, most BTC to ETH swaps settle quickly once confirmations are met, but final timing can still vary with mempool load and network congestion. During high volatility, fixed quotes can expire faster, while floating quotes may return a different final amount than initially shown.

Fixed vs floating quotes

Fixed: locks a quote window, useful when you need more certainty.
Floating: executes at market rate when funds arrive, usually with more timing flexibility.

Network-specific considerations

Always confirm that you are sending on the expected network for BTC. A wrong chain selection is the most common reason for failed or delayed payouts. Before sending, compare the source network shown in your wallet with the quote details to avoid address and routing mismatches.

For ETH, use a receiving address you control and double-check format compatibility with your wallet provider or exchange. If your destination platform requires extra routing fields, verify those requirements before creating the order.

Quotes, slippage, and expirations

Quotes reflect live liquidity and market conditions at the moment they are generated. A floating quote offers more flexibility but can move with the market between send time and execution. A fixed quote helps lock certainty, but only within its timer and confirmation window.

If the quote expires, the safest approach is to request a fresh quote instead of guessing the final output. Sending exact amounts and avoiding delays generally improves execution quality for both speed and final payout.

Privacy checklist

Use fresh receiving addresses where possible.
Avoid mixing unrelated transfer activity in one wallet label set.
For larger sizes, split execution across multiple windows.

Refunds and safety

When a refund is required, processing usually depends on order state, chain status, and policy checks. Keep your transaction hash and payout details available so support can validate the transfer quickly if manual review is needed.

For operational safety, start with a small test swap before sending larger amounts. This confirms address accuracy, network selection, and expected completion flow for your BTC to ETH route.

Troubleshooting

If payout is delayed, verify the deposit transaction confirmations first.
If you sent a different amount, your order may be recalculated automatically.
For address or amount issues, contact support and provide the transaction hash.

Explorer checks

Use a blockchain explorer to confirm the source leg status, number of confirmations, and final broadcast details. Explorer verification helps separate wallet UI delays from actual network settlement problems and is often the fastest way to diagnose status in real time.

Worked example

You hold BTC in your wallet and want to receive ETH to a fresh receiving address.
You generate a quote, verify network details, and send the exact requested amount.
After confirmations, payout is executed and your wallet receives the converted ETH.

Large swaps: best practices

Split larger totals into multiple executions across time windows.
Run a small validation swap first to confirm end-to-end flow.
Keep tx hashes and quote details saved until final settlement completes.
