Build a Uniswap V4 vault hook implementing a ±3σ volatility-adaptive

liquidity range. Two components: SigmaRangeHook (Solidity) + SigmaKeeper

(TypeScript).

SigmaRangeHook

  • BaseHook, bound to a single pool via afterInitialize.
  • ERC-6909 token accounting only. No raw ERC-20 transfers.
  • Issues ERC-20 ShareToken (proportional claim on position + fees).
  • State: tickLower, tickUpper, liquidity, totalShares, feeReserve0/1, lastRebalance, rebalanceCooldown (default 6h).
  • Public: deposit, …

    Delivered the vault, keeper, tests, deployment factory, and self-audit report.

    Clean offline verification: 20 tests passed, including 100k-input fuzz tests. afterSwap execution measured 1,014 gas.

    Full acceptance remains unverified: the Medusa campaign, broader adversarial coverage, and keeper operational gaps are documented with file:line references.
