Execution Engines

Pick how each trade lands — by speed, MEV protection, or landing rate. Untaxed adds 0% on every one.

Overview

Every trade routes through Jupiter, and you choose how it's submitted. There are three top-level modes — Jup, Jito, and Helius — and the Jup mode itself offers three routing paths (Beam, Ultra, and Metis), for five execution paths in total. Select the mode from the toggle row above the buy/sell buttons; the Beam / Ultra / Metis sub-tabs appear under Jup. The choice persists across sidebar refreshes.

Jup (Default)

Jupiter routing across every Solana DEX (Raydium, Orca, Meteora, and more) for best price, with three landing paths to choose from:

Beam — default

Jupiter's sub-second landing pipeline with built-in MEV protection. Untaxed assembles the transaction itself for tight control and appends a private address-lookup table so it fits the packet limit on complex routes.

• Best for: Most trades — the default for a reason
• Speed: Sub-second landing (~400ms typical)
• MEV protection: Transactions invisible to the mempool
• Cost: 0% Untaxed fee. ~0.001 SOL Beam tip + Solana base fee
• Quote token: SOL and USDC

Ultra — fully managed

Jupiter builds, prices, and lands the whole transaction server-side with real-time slippage estimation — you only sign. A priority-fee ceiling protects you from congestion spikes. The lowest-effort option.

Metis — Jupiter V1

Routes via Jupiter's V1 quote and lands through Helius Sender (with an automatic Jito fallback). A reliable alternate path when you want V1 routing.

Jito Bundles

Your transaction is bundled and sent directly to Jito's block engine, which forwards it to validators. This provides MEV protection — your trade can't be sandwiched by bots.

• Best for: High-value trades where sandwich protection matters
• Speed: Slightly slower than Jup Beam (bundle processing adds ~200ms)
• Cost: Priority fee + Jito tip (both configurable)
• Quote: Uses Jupiter Swap V2 /build for routing, Jito block engine for submission
• Quote token: SOL only (USDC mode forces Jup Beam)

Jito Settings

Open the gear icon to configure:

• Slippage % — Default 1%. Jito bundles are atomic, so lower slippage is safer.
• Priority Fee — SOL amount for transaction priority (e.g. 0.0001 SOL). Higher = faster block inclusion.
• Jito Tip — SOL amount paid to the Jito validator (e.g. 0.0001 SOL). This incentivizes validators to include your bundle.

Helius Sender

The most aggressive execution strategy. Your transaction is sent through two paths simultaneously:

1. Staked connections (SWQOS) — Direct validator connections via Helius' staked infrastructure.
2. Jito bundle — Simultaneously submitted to Jito's block engine.

Whichever path lands first wins. This dual-routing gives the highest probability of transaction inclusion.

• Best for: Time-sensitive trades, sniping, contested launches
• Speed: Fastest possible — two parallel paths
• Cost: Minimum bribe of 0.0002 SOL + configurable priority fee
• Quote token: SOL only
• Access: Pro tier — requires 200,000 $UNTAXED

Helius Sender Settings

Uses the same settings as Jito (slippage, priority fee, tip). The tip is used as the Jito bribe when the Jito path is taken.
