Inspiration

The betting industry has been stale since the growth of Web2. Before, betting was a peer to peer action done inside the venue where the event was taking place. However, now big betting industries and casinos control most of the business. They can steal money with abusive policies, block people from betting if they win too much, limit the amount of options of betting if it does not benefit them, asking for too much information about yourself...

What it does

The mission of this project is giving back the power of betting to the people, giving a safe enviroment controlled by smart contracts for tipsters (people with more money that create bets) and challengers (people who join the bets ). Anyone can be a tipster, challenger or both. One tipster selects one match among the available ones (or adds a match if the webpage does not have it!), customizes the bet with the number or maximum challengers, the odds, the maximum bet value... and adds the possible win for all challengers as a collateral. Then, challengers can join the bet. After the match ends, users must enter and claim the rewards.

How we built it

We developed 2 smart contracts in solidity (One comunicating with the dapp frontend and another one focusing on the chainlink products) and a well-detailed frontend using react. The whole project was developed in hardhat.

Challenges we ran into

We had many difficulties to use Chainlink Functions properly. It was the first time that the Blockchain developer used the products and therefore the result might not be the most polished one. But the main issue was gas cost and quantity. The project seems costly to develop using the smart contracts as a backend, and that hindered the development.

Accomplishments that we're proud of

The frontend is very clean and intuitive. It looks like a professional webpage, done in less than a month by the frontend developers. We managed to use 3 chainlink products. We learned to communicate with a time difference of 6 hours within some members of the group.

What we learned

Group management skills. Working with Chainlink products. Exploring ideas that benefit from Blockchain and web3 technology. Setting up the enviroment to develop a Frontend and the Backend(smart contract)

What's next for P2PBetting

Polishing Chainlink functions to achieve the full potential. Adding more betting options. Creating a backend that could lower the amount of information managed by the contract (thus lowering costs for everyone in the process!)
