What should I know before swapping SOL for Bitcoin on an exchange
You should know that swapping SOL for Bitcoin on an exchange service is a multi-step process that involves two separate transactions, network fees on both sides, and a price spread that is usually wider than a direct crypto-to-crypto trade on a DEX. The exchanger does not hold a Bitcoin balance in your name; it receives your SOL, sells it for a stable asset, and then buys Bitcoin and sends it to your address.

You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. dupetheduck.com never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.
Here is what happens step by step, and why each part matters.
The exchanger is not a wallet. You send SOL from your Solana wallet to a deposit address the exchanger provides. The exchanger then converts that SOL into Bitcoin and sends it to a Bitcoin address you specify. You never control a Bitcoin balance on the exchanger's platform. This means you must have a Bitcoin wallet ready to receive the funds before you start the swap. If you provide a wrong or inactive address, the Bitcoin can be lost or require a costly recovery process (covered in detail on the sibling page about sending the wrong amount).
You pay two network fees. The SOL transfer from your wallet to the exchanger incurs a Solana network fee, currently a fraction of a cent. The Bitcoin transfer from the exchanger to your wallet incurs a Bitcoin network fee, which can vary from a few cents to several dollars depending on network congestion. The exchanger usually deducts the Bitcoin fee from the output amount or adds it to the quoted rate. You should check whether the quoted amount includes the Bitcoin fee or if it will be subtracted later.
The exchange rate is not live. The exchanger gives you a rate that is fixed for a short window, typically 10 - 30 minutes. During that window, the rate will not change even if the market moves. If you send SOL after the window expires, the exchanger may recalculate the rate, often at a less favourable price. Always send the SOL as quickly as possible after receiving the quote.
You will not receive the exact Bitcoin amount shown on a price ticker. The quoted amount already includes the exchanger's spread and any fees. The spread on an exchange service is usually wider than on a DEX because the exchanger assumes the risk of holding SOL during the conversion and must cover its operational costs. If you compare the quote to the current market price on an exchange, the quoted Bitcoin amount will be lower.
The swap is not instantaneous. The SOL transaction must confirm on Solana, which takes a few seconds. Then the exchanger must sell that SOL and buy Bitcoin, which can take additional time depending on the exchanger's liquidity and the Bitcoin network's confirmation requirements. Most exchange services send the Bitcoin after one Bitcoin block confirmation, which averages about 10 minutes but can take longer. The total time is typically 15 - 30 minutes, but congestion on either chain can extend it.
You cannot cancel after sending. Once you send SOL to the deposit address, the exchanger will process the swap. There is no "undo" button. If you change your mind, you must wait for the Bitcoin to arrive and then swap it back, paying fees both ways.
The exchanger does not know who you are. Most exchange services require no account or identity verification for swaps under certain limits. However, the transaction is recorded on both blockchains. Anyone can see that an address on Solana sent SOL to the exchanger and that an address on Bitcoin received Bitcoin at roughly the same time. This is not anonymous; it is pseudonymous and linkable by anyone who monitors the exchanger's deposit addresses.
If the Bitcoin network is congested, your swap may take hours. During periods of high demand, Bitcoin transaction fees spike and confirmation times lengthen. Some exchangers will not process a swap until the Bitcoin fee they pay is sufficient to get the transaction confirmed in a reasonable time. You may receive less Bitcoin than quoted if the exchanger adjusts for higher fees.
