• An educational video or infographic explaining sandwich attacks and how users can protect themselves using Solana.

• A smart contract template or guide showing developers how to build DeFi apps resistant to sandwich attacks.

Deliverables

• A working tool with instructions for use.

• An accessible educational resource.

• A smart contract template with explanations.

Evaluation Criteria
