#### **Why DropIn?**

Traditional event tools are:

• Opaque - "Trust me" random winner selections

• Fragmented - Separate tools for check-in, giveaways, rewards

• Not Web3 native - No wallet integration, no on-chain proof

• Easily gamed - QR codes shared online, remote entries

DropIn solves all of this with blockchain-powered transparency.
