Problem Statement

Probana is a prediction market on flow that allows users to bet on anything. Users can create markets and set rules for those markets. We created an order book from scratch that has limit orders, this allows people to queue up prices that they want to buy at, straight in the contract.

Solution

The project uses Flow EVM as the chain we utilize this due to the extremely low block times and extremely affordable gas fees. In order to index the blockchain data we decided to use Alchemy subgraph feature. As our betting token we decided to use USDC because of its stable nature.
