Execution Engines

Three ways to land a trade. Choose based on price, MEV protection or landing rate.

Overview

Every trade in Untaxed is routed through one of three execution engines. Pick the engine from the selector above the buy and sell buttons. Your choice persists until you change it. None of the engines adds an Untaxed fee.

Jupiter Beam (default)

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

• Best for: most trades. It is the default for a reason.
• Speed: sub-second landing, about 400 ms typical.
• MEV protection: built into the Beam pipeline. Transactions are invisible to the public mempool.
• Cost: zero platform fee. A 0.001 SOL Beam landing tip plus the Solana base fee (about 0.000005 SOL).
• Slippage: configurable in trade settings, default 2%.

Jito Bundles

Your transaction is bundled and sent straight to Jito's block engine, which forwards it to validators. Bundles are atomic, so your trade cannot be sandwiched by bots.

• Best for: larger trades where sandwich protection matters, and contested launches.
• Speed: slightly behind Beam. Bundle processing adds around 200 ms.
• Cost: priority fee plus Jito tip, both configurable.
• Routing: Jupiter Swap V2 for the route, Jito block engine for submission.

Jito settings

• Slippage %: default 1%. Bundles are atomic, so tighter slippage is safer.
• Priority fee: SOL paid for transaction priority, for example 0.0001 SOL.
• Jito tip: SOL paid to the validator to include your bundle, for example 0.0001 SOL.

Helius Sender

The most aggressive path. Your transaction is sent two ways at once:

1. Staked connections (SWQOS): direct validator connections through Helius' staked infrastructure.
2. Jito bundle: simultaneously submitted to Jito's block engine.

Whichever path lands first wins. Dual routing gives the highest probability of inclusion.

• Best for: time-sensitive trades, sniping, contested launches, congested network.
• Speed: fastest possible. Two parallel paths.
• Cost: minimum tip of 0.0002 SOL plus a configurable priority fee.
• Access: holder feature. Requires 200,000 $UNTAX.

Helius Sender settings

Shares the Jito settings (slippage, priority fee, tip). The tip is used as the Jito tip when that path wins.
