Build a Sepolia swap-counter hook and fixed-supply token

With meaningful tests and independent review.

Retest the complete swarm by building and launching VolatilityGuard Lab on Sepolia: VolatilityGuardHook, VolatilityGuardToken, independent adversarial review, verified factory deployment with a seeded pool, then a working public swap dapp with explanatory information. Publish real source, receipts, test evidence and the live site. Hook: per-PoolId isolation; bounded observation ring/TWAP and EWMA volatility; adaptive price-deviation limits; rolling volume budget resistant to split swaps; NORMAL/WARMUP/GUARDED/RECOVERY states, stale/low-liquidity handling and deterministic recovery. Authenticate canonical PoolManager callbacks/accounting, never trust sender/hookData identity. Specify both swap directions and exact-input/output, units/rounding, bounded execution and caps. Keep LP exits possible and initialization/warmup non-bricking. Reverts cannot persist breaker transitions. No discretionary admin powers or claim of total MEV protection. Support arbitrary currencies. VGL: Volatility Guard Lab, 18 decimals, no constructor args, fixed 10^27 units minted to deployer, no mint backdoor. Native ETH pair (zero address), static fee 3000, tickSpacing 60; initial sqrtPriceX96 792281625142643375935439503360000 (0.00000001 ETH/VGL). Verify Sepolia PoolManager 0xe03a1074c86cfedd5c142c4f04f1a1536e203543. Use only existing verified periphery, no new deployed helper. Workers never receive keys or broadcast deployments. Deliver pinned/vendored Foundry project, bytecode_hash=none, offline build/test/fmt checks, fuzz/invariant/stress tests for accounting, isolation, manipulation/split volume, unauthorized callbacks, reentrancy, stale history, edge values, recovery and LP exits; report actual counts, gas, failures and limitations. Independent reviewer checks code AND launch manifest; repair blocking findings before deployment. Export ABI JSON and architecture/threat-model/integration docs with exact pool key, quote/swap/liquidity recipes and decoded errors. After verified deployment handoff, build React/Vite/TypeScript + RainbowKit/wagmi/viem in web/, committed relative-base export in dist/. Include hook explanation, risk/limitation information and live pool dashboard (tick/TWAP, volatility, deviation, volume/state/events). Primary ETH/VGL swap UI: amounts, direction, balances/max, real quotes, slippage/minimum received, approvals and wallet-signed swaps, transaction states/errors/explorer links. Support injected wallets without extra credentials. Handle token-sided bootstrap: buy with ETH first; reverse trades depend on accrued ETH liquidity. No fabricated quotes or receipts. Add supported-position exits and clearly labeled simulation demos. Test both directions, wallet/chain states, rejected signing, guard reverts, funds/RPC errors and responsive UI. Complete only when contracts are live, source published and the functional IPFS dapp is reachable.

Build VolatilityGuard Lab end to end in one multi-step job

Implement and test the Uniswap v4 hook and VGL token, independently review the contracts and deployment manifest, deploy and seed the pool on Sepolia through the verified launch pipeline, then build and publicly host a working RainbowKit React swap and observability dapp using the verified deployment.

Original request

Build an ERC-4626 vault with a mock USDC token and deposit/withdrawal tests.

Starting from a tree with nothing in it

Deliver one complete, entirely self-contained static website: choose the layout yourself, write every configuration file by hand, and depend on nothing that must be fetched.

Starting from a tree with nothing in it

Stand up a second complete, self-contained Solidity project: write the build configuration and directory layout from scratch, and implement one small pure library that verifies a Merkle inclusion proof against a root, together with a test suite that exercises it hard — valid proofs at several depths, single-leaf trees, proofs of the wrong length, sibling …

Build a small

Self-contained tool from an empty tree: it reads a file of append-only record entries, checks that each entry's hash links correctly to the one before it, reports the first break clearly, and exits non-zero on any inconsistency.
