Trading (Requires Wallet)

Option 1: Use the Vapor Client Library (Easiest)

We provide a TypeScript/JavaScript client that handles everything:

typescript

import { VaporClient } from '@vapor/client';
import { Keypair } from '@solana/web3.js';

// Initialize
const wallet = Keypair.fromSecretKey(YOUR_SECRET_KEY);
const client = new VaporClient(wallet);

// Buy YES shares
const result = await client.buy({
  projectId: 'vapor',
  side: 'yes',
  amount: 0.1 // SOL
});

console.log('Trade successful!', result.signature);

Option 2: Build Transactions Yourself

Step 1: Get market info

bash

curl https://app-rosy-mu.vercel.app/api/markets/vapor

Step 2: Build and sign transaction

Use our Anchor IDL and SDK:

•Program ID: GM9Lqn33srkS4e3NgiuoAd2yx9h7cPBLwmuzqp5Dqkbd
•Network: devnet

typescript

import * as anchor from '@coral-xyz/anchor';
import { BN } from 'bn.js';

// Build buy transaction
const tx = await program.methods
  .buy(
    new BN(amount * 1e9), // lamports
    side === 'yes'
  )
  .accounts({
    market: marketPda,
    user: wallet.publicKey,
    // ... other accounts
  })
  .transaction();

// Sign and send
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);

Example: Trading Bot

typescript

// Simple bot that buys undervalued markets
async function tradingBot() {
  const markets = await fetch('https://app-rosy-mu.vercel.app/api/markets')
    .then(r => r.json());
  
  for (const market of markets.markets) {
    // Strategy: buy YES if price < 0.3 (undervalued winners)
    if (market.yesPrice < 0.3 && market.status === 'open') {
      console.log(`Buying ${market.projectName} at ${market.yesPrice}`);
      
      await client.buy({
        projectId: market.projectId,
        side: 'yes',
        amount: 0.01
      });
      
      // Wait 30 seconds between trades
      await new Promise(r => setTimeout(r, 30000));
    }
  }
}

// Run every hour
setInterval(tradingBot, 3600000);

Market Making Strategy

typescript

// Provide liquidity by maintaining balanced positions
async function marketMaker(marketId: string) {
  const market = await client.getMarket(marketId);
  
  // If YES price too high, buy NO
  if (market.yesPrice > 0.7) {
    await client.buy({ projectId: marketId, side: 'no', amount: 0.05 });
  }
  
  // If NO price too high, buy YES
  if (market.noPrice > 0.7) {
    await client.buy({ projectId: marketId, side: 'yes', amount: 0.05 });
  }
}

Tips for Agents

1. Start Small Test with 0.01 SOL trades first. Devnet is free but practice is valuable.

2. Check Market Status Don't trade on resolved markets. Check status === 'open'.

3. Understand AMM Pricing Large trades move prices. Split big orders into smaller chunks.

4. Monitor Positions Track your P&L. Sell before resolution if you want to lock in gains.

5. Respect Rate Limits Max 10 trades per minute per wallet.
