Welcome to NuFi wallet's knowledge base. Learn more about NuFi (and access the wallet) on our homepage here or ask a question in our Discord server here.
You can exchange tokens on other [non-Cardano] blockchains for ADA using the Cross-chain exchange functionality. For example, if you have Bitcoin (which uses its own blockchain and isn’t a Cardano token), you can send it from an external wallet, swap it for ADA, and deposit the ADA into your wallet using the Cross-chain exchange. This exchange supports 500+ crypto tokens, all of which can be swapped for ADA.
To use the cross-chain exchange:
Click Exchange in the wallet widget and then choose ‘Cross-chain exchange’; NuFi will open in a new browser tab and you’ll see the Exchange window as shown below
On the left side, select the token that you want to swap for ADA.
The exchange supports 500+ tokens from other blockchains (such as Bitcoin and Ethereum) and all of these tokens can be swapped for ADA.Choose an amount to exchange
On the right side, where it says ‘My account’, ensure that your account is selected as the receiving account
Click Continue, review the exchange details, check the ‘I agree’ box, and click Exchange
You’ll see a confirmation of your exchange order and a payin address; using an external wallet that contains the token you’re swapping, send the specified amount of the token to the unique payin address shown on your screen (below is an example)
Important: to reduce the risk of sending tokens to the wrong address, use the ‘copy to clipboard’ icon to copy and paste the payin address instead of typing it manually.The Exchange service (powered by Changelly) will receive the token you send, then swap it for ADA and deposit the ADA into your wallet.
It can take up to 10 minutes for the ADA to be swapped and deposited into your wallet. If this token isn’t visible after this time, click the Refresh icon to reload your wallet’s contents.
You can see pending, completed and expired exchange orders on the Exchange history tab inside NuFi wallet. Here, you can find the payin address for pending orders if you need this information.
