Next, please add the Shibarium network to your Metamask wallet. You can find the instructions on how to do this here.
After completing the above steps, you will need transaction fees to interact on the Shibarium blockchain, and the fee currency for transactions here is a cryptocurrency called BONE on the Shibarium Testnet. You can obtain Fauce BONE here.
Once you have obtained your BONE tokens, you can now participate in the Airdrop on Pi Swap program running on the Shibarium Testnet.
