IMPORTANT NOTE: Write down your recovery words in the order you see them on the screen. Write them down a piece of paper and store it somewhere secure. Take your time and triple check each word. Do not store your seed in a digital format (photograph, text document). Whoever has the access to your seed and your password can access your funds. Confirm that the seed has been properly backed up.

# Connecting Wasabi to BTCPay Server Full Node (If you're self-hosting BTCPay)

After wallets are connected, it is highly-recommended to connect Wasabi Wallet to your full node in BTCPay. The process is easy, but can only be done if you self-host BTCPay and are logged in as Admin. Tor has to be enabled in BTCPay (it is enabled by default). This process enhances privacy even further.

In BTCPay, go Server Settings > Services > Full node P2P > See Information. On the BTCP-P2P page, click on the Show Confidential QR Code. Bellow the QR Code, there's a link See QR Code information by clicking here, so click on the link to reveal your string. Copy the string but remove bitcoin-p2p:// part.

In Alternative Block Source / Bitcoin P2P Endpoint, paste the endpoint.

Restart Wasabi.

# Configuring the Gap Limit in Wasabi

In the top menu, select click on the File > Open > Wallets Folder. Shortly the json file will be shown in a sub-folder. Open that file with a text editor like notepad. Locate "MinGapLimit": 21, change it to "MinGapLimit": 100, and save the file.

There's no good answer to how much you should set the gap limit to. Most merchants set 100-200. If you're a big merchant with high transaction volume, you can try with even higher gap limit.

For more details about the Gap Limit, check the FAQ.

Wasabi Wallet and BTCPay Server are now connected. Any payments received to your BTCPay will be visible in Wasabi, where you can further spend or mix them.
