Make sure to not share or lose the secret recovery phrase (mnemonic)
If you already have a wallet, you can restore it on Phantom using the associated seed phrase. Follow the online instructions to restore your SOL account.
Once you entered the 12 or 24 words you can then restore your wallet and optionally set a password on your account.
Once you have funded your Phantom wallet with Solana, you can click on the Phantom extension to see your account details.
Once logged in, you will be able to view all the SPL assets that you possess. If you do not already have SOL tokens you can get them from a friend or buy them off-exchange and transfer those to your wallet.
Once you do that you will be able to see the SOL tokens in your wallet.
Go ahead and click your SOL balance and on the top right, you will see 3 dots. Click the dots to reveal the staking menu. Click the menu-item Stake SOL
You will be shown a list of validators along with a search button. Go ahead and type Chorus One in the search panel. Chorus One's validator will show up. Go ahead and click on the validator name.
Choose the amount of SOL you would like to stake and click on Stake
Make sure to leave some SOL in your account to pay for the transaction fees
Once you click Stake you will immediately see that your wallet is staking your SOL to your chosen validator. You can also click on the View Transaction link to see the status of your transaction in a blockexplorer. If you look at the Confirmations field you can slowly see it increasing from 0 to 32. Once it reaches the MAX number of confirmations your transaction gets added to the blockchain
Make sure to note down the transaction hash or the link provided on the screen. This allows for easier debugging in case of a failed transaction.
After your transaction is successful you can go back to your Phantom wallet, click on the Solana balance, and see your stake accounts.
Congratulations! You are now staking your SOL!
If you click on your stake accounts you will see that your stake is activating. It takes 1 epoch for your stake to activate. An epoch in Solana lasts for approximately 2-3 days. After this period your stake will show up as active and will start earning rewards.
If you click on your stake balance, you will be given the option to unstake. Unstaking also takes an epoch. Once you click Unstake your stake will start deactivating and will become fully inactive after a maximum of 3 days (1 epoch).
After the stake become inactive you can withdraw it back to your Solana account
