[mollybeach]

Summary

Current Base Sepolia status

Contract	Deployed
HedgePodVault	✅
AutoYieldToken	✅
YieldOracle	✅
VolatilityFeeHook	❌

Impact

• Uniswap v4 dynamic fee demo on testnet is incomplete
• frontend/app/uniswap-implementation/page.tsx shows "(Coming soon)" for hook-related items
• Integration tests against live hook address cannot run on Base Sepolia

Steps

1. Fix post-deployment configuration in scripts/deploy/deployer.ts
2. Deploy VolatilityFeeHook: npx hardhat run scripts/deploy/deployer.ts --network baseSepolia
3. Verify on BaseScan
4. Update ABIs in deployments/abis/
5. Wire hook address into frontend Uniswap pool stats component

Acceptance criteria

• VolatilityFeeHook deployed and verified on Base Sepolia
• Hook address documented in deployments/ and contracts page
• Uniswap integration page reflects deployed status
