Burning Cards via custom_json

In most cases, burning cards is possible directly through the in-game interface, but for Soulbound Foundation Cards, this option is disabled to prevent accidental burns. However, players can still perform burns manually through custom JSON transactions on the blockchain.

Soulbound Foundation Cards are earned exclusively through Campaign mode and are different from the non-soulbound versions that can be obtained through regular gameplay or by opening Foundation Packs. These cards are permanently bound to your account, meaning they cannot be traded, sold, or transferred.

If you’d like to burn your Cards, here’s how you can do it manually through a custom JSON transaction:

1. Log in to Your Account www.splinterlands.com with hive keychain and make sure you’re logged in to the account that owns the cards you plan to burn.

2. Locate in your collection the card ID of each card you want to burn. Write them down, you will need them later.
   
   Example: C16-822-10CIHHFZ4G
   
   (All Soulbound Foundation cards IDs start with C16.)
   
   

3. Navigate to the Broadcast Page https://splinterlands.com/broadcast.

4. Set Up the Transaction as follows:

5. Operation: Custom Operation

6. Operation ID: sm_burn_cards

7. Key Type: Active

8. In the JSON field, use the following format — replacing the example IDs with your own card IDs:
    

   {
     "cards": ["C16-822-10CIHHFZ4G"]
   }

   
    

9. Verify it looks correct and Broadcast the transaction confirming the transaction with hive keychain.

{
  "cards": ["C16-822-10CIHHFZ4G", "C16-899-2VX771AOTC"]
}
