From “I want to swap BTC for ETH” to “ETH is in my wallet” — here’s exactly what happens, and what we’re doing behind the scenes.
Choose the coin you’re sending and the coin you want to receive. We quote a real-time rate sourced from the best route across centralized and DEX liquidity.
Tell us where to send the destination coin. We validate the address against the right network so you don’t accidentally send ERC20 to a BTC address.
You’ll see a one-time deposit address (or QR) for the source coin. Send the agreed amount from your wallet — that’s the only manual step.
Your deposit hits the liquidity pool, the trade executes, and the destination coin is sent to your receiving wallet. Status flips to “Finished”.
The boring engineering that makes the whole thing feel boring.
Every quote pings 12+ liquidity venues — CEX order books, DEX aggregators, OTC desks — and picks the route with the best net rate after fees.
Either both legs settle or neither does. If a route fails, your deposit returns to the refund address automatically — usually within 15 minutes.
Wallet addresses sit in a hot index for the duration of the swap, then expire. We don’t link transactions to IPs, devices, or sessions.
| Swap spread | 0.4–0.9%, baked into the quote |
| CoinSwapr fee | $0 |
| Withdrawal fee | $0 |
| Network fee | Whatever the source chain charges |
The number the widget shows is the number that lands in your wallet, minus the destination network fee.
| BTC → ETH | 5–12 min |
| ETH → SOL | 3–6 min |
| USDT (TRC20) → USDC (ERC20) | 2–5 min |
| XMR → BTC | 10–25 min |
Times depend on network congestion. We display a live ETA on every swap.

By default it floats — you get the live market rate at the moment your deposit confirms. You can opt for a fixed rate at quote time; the platform charges a small extra spread to cover the risk of the locked window.
If you underpay, the system completes the swap at a proportionally smaller amount. If you significantly overpay outside the quoted range, you’ll be prompted to either confirm at the new amount or refund — refunds go to the address you optionally provided at create time.
No. Once your deposit hits the deposit address with the required confirmations, the swap executes and the destination coin is forwarded automatically. There’s no second click, no email confirmation, no manual approval.
All major chains — Bitcoin, Ethereum, Polygon, BNB Chain, Arbitrum, Avalanche, Solana, Tron, Monero — plus the most common stablecoin variants on each (USDT, USDC, DAI). Pick the chain when you choose your asset; we validate the address against it.
Most pairs settle in 5–10 minutes. Stablecoin-to-stablecoin within the same chain is faster (2–5 minutes). Bitcoin and Monero deposits take longer because their networks need more confirmations — usually 10–25 minutes total.
The widget shows a live ETA that adjusts to current network conditions. If your deposit confirmation is delayed by congestion, the swap waits for it — the rate quote stays valid for the window you selected.
