Since then, the platform has grown to secure over 100+ individual projects, $1.4M+ of AVAX burned (reducing supply), 950+ individual block-producing validators, and over 500k+ community members around the globe. Decentralized finance (DeFi) applications can be found on Avalanche such as Pangolin, TraderJoe, and more.
