Sniper Dynamics and Mitigation

Initial Assessment

• Launch mechanism (mint, LP go-live, auction)?
• Time of launch and publicity level?
• Infrastructure: RPC capacity, rate limits, bot detection available?
• Tolerance for delays or caps?

Core Principles

• Snipers exploit speed and predictable times; randomness and caps reduce edge.
• Defenses must not break legitimate users.
• Publish rules clearly; avoid hidden blocklists where possible.

Workflow

1. Threat model
   • Identify likely bot vectors: pre-announced time, predictable tx, mempool monitoring.
2. Choose mitigations
   • Options: per-wallet caps, staggered windows, randomized start within small window, delayed LP trading, higher fees first block, allowlist/raffle.
3. Technical controls
   • RPC rate limits per IP/API key; captcha on UI; proof-of-work or queue.
   • Monitor mempool/logs for bursts; auto-pausing if error rate spikes.
4. Execution
   • Implement in UI + backend; test with bot-like scripts on devnet.
5. Communication
   • State mitigations and rationale; publish what is allowed; avoid surprise blocks.
6. Post-launch response
   • Track top buyers; if overwhelming, consider additional liquidity or caps for future drops; share data transparently.

Templates / Playbooks

• Launch window plan: e.g., 5-minute randomized start within 30-minute window.
• Cap policy: max X tokens per wallet for first Y minutes; enforced on-chain or via UI + backend validation.
• Monitoring dashboard: tx success rate, unique wallets, top buyers, RPC errors.

Common Failure Modes + Debugging

• Over-aggressive filters blocking real users: test on varied devices; provide fallback path.
• Mitigations only in UI; bots hit RPC directly: enforce on-chain when possible.
• Randomized start without communicating window -> confusion; be explicit.
• Snipers bypass caps via multiple wallets: acknowledge limitation; monitor and publish stats.

Quality Bar / Validation

• Mitigations implemented and tested; false-positive rate low.
• Rules published pre-launch with clear timelines.
• Monitoring active during launch; post-mortem produced if bots dominate.

Output Format

Examples

• Simple: Per-wallet cap 1 mint, captcha on UI, randomized start within 10 minutes; post stats showing distribution.
• Complex: LP go-live with delayed trading 2 minutes, API rate limits, bot watch dashboard, and fallback RPC; publish post-launch report on top wallets and mitigation effectiveness.
