How to Bridge SPS Between Splinterlands and Base (Guide)

How to Bridge SPS Between Splinterlands and Base (Guide) - by @bamlolx and @endecs

Since we don't have a dedicated UI yet, but many users are eager to bridge their SPS tokens to Base, here's a simple guide. You can do this yourself without any programming knowledge.

Go to the Broadcaster Page:
First, navigate to the following page:

https://playground.splinterlands.com/broadcaster.html

https://cdn.discordapp.com/attachments/1258779525739974778/1407409777646239899/image.png?ex=68a5ffff&is=68a4ae7f&hm=c025ea3b1a6d59742e07657c8ca64e6b50591d7c2b9a20f3cfc15dacdaa10d9f
This page allows you to broadcast a custom_json operation to the Hive blockchain. (Once our UI is ready, this process will be handled automatically in the background).
Fill in the Broadcast Form:

ID (Type of custom_json):
Enter: sm_token_transfer

Key Type:
Select: Active
The Active key is required for token transfers.

Display Message:
This field doesn't matter; you can type anything here.

Hive Account:
Enter the username of the Splinterlands account you are transferring SPS from.

CustomJson Code:
Paste the following JSON structure into this field. This is the most important part.

custom_json:

{
    "to": "spsonbase",
    "token": "SPS",
    "qty": 1,
    "memo": "bridge:validator-base-sps:0x5C17E1F79B151db0073bdBAd9cF39137661c1529"
}

Explanation of the JSON fields:

qty: The amount of SPS you want to transfer from your in-game balance to Base.

memo: CRITICAL – You must replace the address 0x5C17E1F79B151db0073bdBAd9cF39137661c1529 with your own Base wallet address.

⚠️ WARNING: Always test with a small amount first! If you make a mistake in the memo field (e.g., a wrong address), your SPS will be lost permanently.

View Your SPS on Base (e.g., in MetaMask):
Once the bridge is complete, to see your SPS tokens in your wallet (like MetaMask), you need to import the token:

select Base Mainnet
click on the 3 dots
Import tokens
Custom token - Base Mainnet

For the Token Contract Address, use:
0x578661E9A09Eee6b2cd97D4Ded1CCBaE7B8516B9

The token symbol (SPS) and decimals should auto-populate.

Bridging SPS from Base Back to Splinterlands

The process for sending SPS from Base back to Splinterlands is more complicated from a user's perspective. Currently, I haven't found a simple method. This typically means a user would need to use a developer-oriented tool or a custom-built dApp interface.

If anyone in the community knows of a simpler, user-friendly way to initiate this reverse bridge (e.g., a public dApp website), please send me a direct message (DM). I will gladly update this guide with the instructions.
