BetMe

BetMe is a decentralised, peer-to-peer prediction market, built via Account Abstraction technologies for improve UI experience.

How it's works

grid

For build AA and gasless transaction we use combination of Gelato 1Balance && Relay, Web3Auth and Safe Contract Address. To display current prices on the UI, we using the RedStone API. On the contract side, we implemented the RedStone Price Feed to obtain current prices and close bets. The Gelato Web3 functions are responsible for generating and updating the redstonePayload (byte code required for the getPrice function) and controlled the expiration of bets for distribute funds.

Ethereum Smart Contracts

Three smart contracts were written in Solidity for BetMe:

  • CustomChallenge.sol - This contract responsible for Custom bets. Deployed on Mumbai Testnet 0xDb0C8933A0EEe4a07d8A524f27E9041fA58C0AFc
  • PriceChallenge.sol - This contract responsible for Price bets. Extend RedStonePrice contract. Deployed on Mumbai Testnet 0xbB2c5955eFf974Dd4F870f4902183732318C9415

Here are some quick links to code in this repo, including some examples of where hackathon sponsor tech was used:

Installation

These instructions will get you a copy of the project up and running on your Mumbai testnet for development and testing purposes.

Prerequisites

nodeJS >= 16.0
npm

Install dependencies and create environment file:

npm install
cp .env-example .env

Fill environment variables.

Deploy & run

npx hardhat run smart_contract/scripts/deploy.js --network mumbai
npm run start

Build for Production

npm run build

Create Gelato Relay Apps

  1. Go to https://relay.gelato.network/apps
  2. Deposits some tokens to 1Balance
  3. Create App and copy Api Key
  4. Fill GELATO_API_KEY on .env

Create Gelato Web3Function task

  1. git clone https://github.com/darcksday/betme-gelato-functions
  2. npm install
  3. cp .env-example .env
  4. Fill environment variables.
  5. npx w3f deploy src/web3-functions/my-web3-function/index.ts
  6. Copy CID
  7. Go to https://app.gelato.network/
  8. Create task with you contract and CID

Next Steps

  • Run on mainnet and add ability deposits via credit card
  • Launching pool bets, with dynamic coefficient and unlimited participants
  • Dynamic automated events (sources of information for Oracle setup manually)
  • Add ability to bet for more assets,real-world events,sport, politics etc.
