About

This Solana program showcases the tools and techniques used to create Binary Options on the Solana blockchain.

The program is structured around three key instructions:

• initialize: The instruction for the market maker to initialize the Binary Option.
• do_bet: The instruction to place a bet.
• resolve: The final step, where the program distributes prizes and closes the accounts.

How to run

1. Install solana development suit.

2. Install the dependencies:

   anchor build

3. Build:

   anchor test

Main Challenges

• Scheduling instruction execution on the Solana chain proved to be challenging. The main approach involved using the clockwork-sdk, which is now deprecated and incompatible with the latest versions of Anchor. Considering this, the most efficient solution is to schedule the resolve instruction execution off-chain.
• Pyth Oracle does not exist on Solana Localnet, forcing developer to mocked prices for tests. Other Oracles were not explored due to time constraints.
