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.
Jupiter Ultra (Default)
The simplest and fastest option. Your trade is routed through Jupiter's aggregator, which finds the best price across all Solana DEXes (Raydium, Orca, Meteora, etc.).
- Best for: Most trades, especially smaller amounts
- Speed: Fast — single transaction, no bundle overhead
- Cost: Zero markup from Untaxed. You pay only Solana's base transaction 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 Ultra (bundle processing adds ~200ms)
- Cost: Priority fee + Jito tip (both configurable)
- Quote: Uses Jupiter V6 API for quoting, Jito block engine for submission
- Quote token: SOL only (USDC mode forces Ultra)
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:
- Staked connections (SWQOS) — Direct validator connections via Helius' staked infrastructure.
- 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.
