SDK Example Usage: Build Your Own Prediction Market Frontend

Depredict is designed for builders. You can use the SDK to create your own custom prediction market frontend, dApp, or integration. Here's how to get started:

1. Initialize the SDK

import { Connection, PublicKey } from '@solana/web3.js';
import DepredictClient from '@endcorp/depredict';
 
const connection = new Connection('https://api.devnet.solana.com');
const adminKey = new PublicKey('...'); // Your admin public key
const feeVault = new PublicKey('...'); // Your fee vault public key
 
const client = new DepredictClient(connection, adminKey, feeVault);

2. Fetch and Display Markets

const markets = await client.trade.getAllMarkets();
// Render these in your UI

3. Create a New Market

await client.trade.createMarket({
  startTime: Date.now() / 1000,
  endTime: (Date.now() + 86400000) / 1000, // 24 hours from now
  question: 'Will SOL be above $200 by tomorrow?',
  metadataUri: 'https://your-metadata-url',
  payer: adminKey,
  oracleType: 'manual', // or 'switchboard'
  marketType: 'live', // or 'future'
  feeVaultAccount: feeVault,
});

4. Place a Trade (Open a Position)

await client.trade.openPosition({
  marketId: 1, // The market you want to trade on
  amount: 100, // Amount in USDC
  direction: { yes: {} }, // or { no: {} }
  token: 'USDC_DEVNET_ADDRESS', // Token address for trading
  payer: /* user's public key */,
  metadataUri: 'https://your-nft-metadata',
});

5. Settle and Resolve Markets

Use resolveMarket to resolve outcomes (admin or oracle)
Use payoutPosition for users to claim winnings

You can build any UI/UX you want on top of these primitives—leaderboards, custom market creation flows, trading bots, and more. The SDK is open, composable, and ready for your ideas!
