Copy the service node public key into the box at the top of the screen labelled 'Service Node Key'
Enter the amount of Oxen you wish to stake in the other box. The minimum stake amount will be listed on https://oxensn.com, but to work it out yourself you can simply divide the amount of Oxen available to stake by the number of slots left for that Service Node.
For example, if a node had 2 slots remaining and 7500 Oxen available for stake, the minimum contribution would be 7500/2 = 3750 Oxen.
Once you have entered the Service Node public key and the amount you wish to stake, simply swipe 'Stake Oxen' to contribute to the Service Node.
Congratulations! You're all staked up, and you'll receive your Service Node rewards directly to your wallet.
To unlock your stake from a Service Node, navigate to the stakes section of the wallet your contributions will be listed. You can unstake a contribution by swiping left and confirming. Your Oxen will be unlocked after 15 days.
