Landing Solana
transactions
under extreme contention.

How Jito and writable accounts actually work.

Solana's parallel engine handles separate state paths, but execution clashes when transactions compete to write to the same account. Jito coordinates this off-chain in three steps.

Denominator optimization wins auctions.

Inside a Jito Conflict Set, bundles are ranked by Priority Score — tip density per compute unit — not absolute tip.

Tx B pays a 14× higher absolute tip yet loses — because its CU denominator is bloated. AutoLand shrinks that denominator.

Six layers, one contention engine.

AutoLand builds an active bidding profile for target accounts. Live gRPC streams feed tip scaling; global fee percentiles hold the floor when pools are quiet.

// 1. Bot detects pool imbalance
const pool = await getDLMMPool(POOL_ADDR);

if (pool.priceChange > threshold) {
  // 2. Build rebalance txs
  const txs = await buildRebalanceTxs(pool);

  // 3. Hand batch to AutoLand
  const result = await autoland.submitBatch(txs, {
    targetPool: POOL_ADDR,
    outbidMultiplier: 1.15
  });
}

// Example 1: High Urgency transaction (DLMM rebalancing, arbitrage, liquidations)
const highResult = await autoland.submit(rebalanceTx, {
  urgency: "high" // Routes to the private Jito block engine stack with dynamic tip outbidding
});

// Example 2: Normal Urgency transaction (Standard token transfers, admin tasks, fee collections)
const normalResult = await autoland.submit(transferTx, {
  urgency: "normal" // Bypasses Jito tips entirely; dispatched directly to standard public RPC nodes
});
