SOL is the native #cryptocurrency of the [[Solana]] #blockchain. It's like the fuel that powers the network. Users need SOL to pay for transaction fees and interact with decentralized applications ([[dApp]]s) built on Solana. You can also use SOL to participate in staking, where you essentially lock up your tokens to help secure the network and earn rewards in return. The value of SOL fluctuates based on supply and demand, just like other cryptocurrencies.
