MEV & Security Architecture
Neutralizing searcher frontrunning, toxic price impact, developer Sybil traps, and stealth liquidity drains.
1. Pre-Execution Price Impact & Sandwich Guard
Solana memecoin bonding curves operate on constant product AMM mechanics ($k = x \cdot y$). Large trade sizes in shallow curves cause severe price impact, allowing MEV searchers to execute sandwich attacks. Sandwich Guard calculates the impact before submission:
• If Price Impact $\ge 4.0\%$: Slippage is automatically clamped from 15% to 5%, and trades are split into micro-orders.
2. Jito Multi-Region Block Engine Racing
Bypasses standard public RPC gossip mempools. The agent packages the swap instruction with a dynamic Jito tip transfer and broadcasts the bundle concurrently via Promise.any to all global Jito Block Engines:
3. Sybil Multi-Wallet Cluster Detector
Bad actors deploy tokens and immediately buy 20-40% of the supply across 5-10 disguised puppet wallets in Block 0. The Cluster Detector flags:
- High-velocity bursts: $\ge 5$ distinct wallets purchasing in under 2 seconds.
- Amount symmetry: Multiple wallets buying identical amounts (e.g. 4 wallets buying exactly 0.250 SOL).
- Volume spikes: More than 8.0 SOL injected within 3 seconds of launch.
