XP is your progress score inside the Blockstreet Vault. Everytime you lock tokens, participate in Vault activities, or engage with the ecosystem, you earn XP.
XP doesn't represent money, it's a way to measure your activity and commitment. Higher XP unlocks additional perks, boosts your leaderboard rank, and can qualify you for rewards, special access, and future Blockstreet opportunities.
In short: the more active you are in the Vault, the more XP you earn, and the more benefits you unlock.
