Boosts are multipliers that can increase your points. Some boosts are global (apply across campaigns), while others are campaign-specific.
Common ways to unlock boosts include staking $CGPT, posting dedicated ChainGPT content (Ambassador), maintaining post-campaign activity (Loyalty), following and verifying a project (Follower), or completing project-defined missions (Custom Actions). Your campaign page and “My Stats” panel show which boosts you currently have and their multipliers.
