Threat Model

1. Bot Attack Scenarios

MayhemShield protects token launches from “Mayhem Bots”, các bot tự động lợi dụng các khoảng trống trong launch để pump-and-dump.

Scenario A: Single Wallet Pump & Dump

• Attack flow:

  1. Bot detects newly added liquidity.

  2. Executes multiple buy transactions in a few seconds to pump price.

  3. Immediately sells to capture profit → sudden price drop.

• Impact:

  • Panic selling by holders

  • Slippage spikes

  • Token price crash within minutes

Scenario B: Multi-Wallet / Sybil Attack

• Attack flow:

  1. Bot operator creates hundreds/thousands of wallets.

  2. Executes many small transactions across these wallets.

  3. Bypasses maxTx restrictions on a single wallet, but cumulatively dumps a large amount.

• Impact:

  • Harder to detect by simple per-wallet rules

  • Artificial volume inflates price temporarily

  • Large coordinated dump after launch window

Scenario C: Mempool Manipulation

• Attack flow:

  1. Bot monitors mempool transactions before they are confirmed.

  2. Front-runs or back-runs liquidity add.

  3. Snipes tokens to gain cheap entry → dumps immediately.

• Impact:

  • Early deployer suffers loss of liquidity

  • Initial holders exposed to immediate price swings
