To stake SHM tokens and participate in the Shardeum program, you will need to follow these steps:
1. Add the Sphinx 1.X network to your MetaMask wallet by following the instructions on the official Shardeum website.
2. Visit the Shardeum website and go through the token claiming process for 15 test SHM tokens as instructed on the page. You will need to paste the link to your MetaMask address tweet and click the "Tweet Now" button.
3. Once you have received the 15 SHM tokens, return to the Shardeum Dashboard.
4. In the Dashboard window, connect your wallet and click on the "Add Stake" button. Then select the amount of tokens you wish to stake (e.g., 12) and click "Stake."
5. It is recommended to periodically check the Dashboard to ensure that your node continues to operate. In some cases, a node restart may be required.
Please note that these steps are general and may vary depending on the specific implementation and updates of the Shardeum project. Follow the instructions provided on the official Shardeum website and in your personal Shardeum account for the best outcome.
