Here's the swap guide for your reference:

Step 1: Go to the official swapping page of TurtleCoin: https://explorer.turtlecoin.lol/swap

Step 2: Drop your FTM wallet address into that box under the heading My TRTL to wTRTL Wrap Transactions. Click on the "look up" button. 

Step 3. By clicking on this button, you will be given a unique TRTL address to which you should send your current TRTLs. You can do the transfer by using the "Standard Address" plus the "Payment ID (which is known as memo too")  or just use the "Integrated Address" to do the transfer. 

*We recommend you use the "Standard Address" plus the "Payment ID" 

Step 4: Send your TRTL to the above unique given address. After block confirmations have passed, you'll get wTRTL in your FTM wallet.

Please note:

• Swap ratio: 100,000 TRTL:1 wTRTL
• Due to the swap penalty and swap fees charged during the swap,  the amount of wTRTL you receive will not be exactly 100,000:1. Please refer to the figure below:
