🚀 Quick Start: Launch Your Own Market

1. Install the SDK:

   npm install @endcorp/depredict

2. Create a Market (TypeScript Example):

   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 usdcMint = new PublicKey('...'); // USDC mint address
   
   const client = new DepredictClient(connection, adminKey, feeVault, usdcMint);
   
   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'
   });
