The Solana token, also known as SOL, plays a crucial role in the Solana Ecosystem. It is used for staking, which is a process that helps secure the network and validate transactions. SOL is also used to pay for transaction fees on the network. Additionally, it is used in the governance of the network, allowing holders to vote on proposed changes to the system. The token therefore serves multiple purposes, contributing to the overall functionality and security of the Solana Ecosystem.
