Like all blockchain networks, Solana needs validators to process transactions and keep things running smoothly.
The validators that contribute here are rewarded for doing so, and those rewards come from network transaction fees and protocol emissions. When your SOL is deposited into Sanctum App, it's then staked on the Solana network through Sanctum's validator.
Our validator earns fees for processing transactions on your behalf, and a portion of those fees flow back to your app account as daily rewards. Once your SOL is deposited, it starts working for you automatically and there's no need for you to do anything extra to earn rewards.
In Sanctum App, your SOL grows every day while you go about your life. No need to watch charts all day! As long as the network is running and processing transactions as it has for over six years now, stakers earn rewards.
It is one of the simplest ways to grow your SOL.
