- Click the "Leap" button;
- Enter your Bitcoin address;
- Select the RGB++ assets you want to Leap back to L1 and specify the amount;
- Choose a FeeRate (ensure your Bitcoin wallet has a sufficient UTXO balance for the fee);
- Click the "Leap To Bitcoin L1" button;
- Click the "Prepare" button;
- Sign to confirm the transaction;
- Click "Track Status" to monitor the progress; you can also view it in "Ongoing Leaps".
Complete the leap
