"How to Build a Solana Arbitrage Bot in 2026"

Why Solana?

Solana's sub-second block times and near-zero transaction fees make it the only L1 where retail arbitrage is actually viable. Ethereum L1 is too slow, L2s fragment liquidity.

Core Architecture

Your arbitrage bot needs three components:

1. Price Scanner — polls DEXes for spread opportunities
2. Execution Engine — submits swap transactions atomically
3. Monitoring — tracks P&L and alerts on failures

Price Scanner

The scanner fetches quotes from multiple DEXes simultaneously. On Solana, the key DEXes are Jupiter (aggregator), Raydium (AMM), and Orca (concentrated liquidity).

const scanner = async () => {
  while (true) {
    const routes = await jupiter.getRoutes({
      inputMint: SOL,
      outputMint: RAY,
      amount: scanAmount,
      slippage: 0.5,
    });
    
    for (const route of routes) {
      if (route.priceImpact > MIN_SPREAD) {
        await executeTrade(route);
      }
    }
    
    await sleep(1000);
  }
};

Execution Strategy

The trick is executing before the spread closes. You need:

• A pre-funded hot wallet
• Priority fees (0.001-0.01 SOL) to jump the queue
• Fallback RPC endpoints (we use 3+)

Real Results

Our Strike Engine has executed 2,700+ trades. The key insight: REVERSE direction (buying the dip and selling the spike) is consistently more profitable than chasing momentum.
