How we built it

To build the application, the technologies listed below were used:

Blockchain: Ethereum Sepolia
Blockchain Primitives: Stablecoin - ERC20
Front-End: React, Metamask Wallet, Web3.js, Shadcn-UI, Vite and Lucide icons
Back-End: API and OpenAI
Chainlink Oracles: Chainlink Functions and Chainlink Automation
Programming languages: Solidity and TypeScript
Deploy: Vercel

Challenges we ran into

We had delays on several occasions.

One of our Devs lives in the region that was affected by the tragedy in Rio Grande do Sul, responsible for Front-End, and his computer was damaged.

One of our Back-End DEVs had to travel for work in the middle of this period.

We need to believe in ourselves especially in difficult times.

Accomplishments that we're proud of

We managed to deliver the project within the period despite the difficulties encountered along the way and correctly using Chanlink's Tools.

We wish we serve as an inspiration for new developers to join web3.

What we learned

We learned using ChainLink's tools like Oracle Function and integrating it with external API to solve our interoperability problem. Using the API of Football we were able to bring real-time data from the Brazilian Series A Championship and display it in a decentralized way on the Smartbets Platform.
We learned having good networks will help you get out of trouble.

What's next for Smartbets

Much remains to be done, but we will seek investment for improvements

Hiring legal advice to be able to continue acting legally, as Online Sports Betting has been undergoing several updates.
Law 14,790/23, sanctioned in December 2023, allows private companies to operate sports betting online and in physical establishments, such as betting houses and casinos. However, it brings with it a series of changes in the sports betting scenario in Brazil.
Implementation of website performance improvements
Adding ChainLink VRF to provide more transparency in NFT distribution.
Studying news tokenomics and staking of ERC20 tokens to get more staking.
Getting feedback to adjust product design as needed.
