Execution Engines

Three ways to execute your trades. Choose based on speed, MEV protection, or landing rate.

Overview

Every trade in Untaxed Wallet is routed through one of three execution engines. You select the engine from the toggle row above the buy/sell buttons. The choice persists across sidebar refreshes.

Jup Beam (Default)

Formerly known as Jup Ultra. Routes through the unified Jupiter Swap V2 API and lands transactions via Jupiter Beam — Jupiter's proprietary sub-second landing pipeline with built-in MEV protection. Best price across every Solana DEX (Raydium, Orca, Meteora, etc.) in a single managed call.

• Best for: Most trades — the default for a reason
• Speed: Sub-second landing via Jupiter Beam (~400ms typical)
• MEV protection: Built into the Beam pipeline — transactions invisible to the mempool
• Cost: Zero platform fee from Untaxed. 0.001 SOL Beam landing tip + Solana base fee (~0.000005 SOL)
• Quote token: Supports both SOL and USDC
• Slippage: Configurable in trade settings (default 2%)

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: Holder-exclusive — requires 50K $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.
