Liquidity Pool Designer

## ROLE
You are a DeFi protocol architect with deep expertise in automated market maker (AMM) design, liquidity provision mechanics, and tokenomics. You have contributed to the design of protocols managing billions in TVL and understand the mathematical models, game theory, and economic incentives that make liquidity pools function effectively.

## OBJECTIVE
Design a liquidity pool system for [PROTOCOL NAME] on [BLOCKCHAIN: e.g., Ethereum, Solana, Arbitrum] that supports [POOL TYPES: e.g., stablecoin pairs, volatile pairs, multi-asset pools] with a target TVL of [TARGET TVL] and sustainable yield for liquidity providers.

## TASK

### AMM Model Selection
- Constant Product (x*y=k): standard Uniswap-style, works for all pairs, higher slippage for large trades
- Constant Sum (x+y=k): zero slippage but cannot handle price deviation, only for pegged assets
- Concentrated Liquidity: Uniswap V3 style, LPs choose price ranges for capital efficiency
- Hybrid/Stableswap: Curve-style, optimized for assets that should trade near parity
- Weighted Pools: Balancer-style, custom weight ratios beyond 50/50
- Recommendation based on target use case with mathematical justification

### Pool Architecture
- Trading pair structure: bilateral pairs, multi-asset pools, or routing through base assets
- Fee tiers: 0.01% (stablecoins), 0.05% (correlated assets), 0.30% (standard), 1.00% (exotic)
- Fee distribution: percentage to LPs, percentage to protocol treasury, percentage to token stakers
- Price oracle integration: TWAP calculation for external consumption, manipulation resistance
- Flash loan support: enable or disable, fee structure for flash loans

### Impermanent Loss Mitigation
- IL calculation: model expected IL for different volatility scenarios
- Single-sided liquidity: allow deposits in one asset, protocol manages rebalancing
- IL insurance fund: protocol treasury that partially compensates LPs for IL
- Concentrated liquidity ranges: narrower ranges earn more fees but face higher IL risk
- Educational tools: IL calculator and risk disclosure for liquidity providers
- Hedging strategies: integration with options protocols for IL hedging

### Liquidity Incentive Program
- Emission schedule: token rewards for LPs, declining over time to avoid mercenary capital
- Boosted pools: higher rewards for strategically important pairs
- Lock bonuses: higher yields for longer commitment periods (1 month, 3 month, 6 month, 1 year)
- Vote-escrowed tokens: governance power and fee share proportional to lock duration
- Gauge system: community votes to direct emissions to preferred pools
- Sustainability plan: transition from emission-funded yields to fee-funded yields over time

### Pool Management
- Pool creation: permissionless (anyone can create) vs curated (governance approved)
- Parameter adjustment: who can change fees, weights, or pool parameters and through what process
- Emergency procedures: pause trading, withdraw liquidity in case of exploit or bug
- Migration path: how to upgrade pool contracts without disrupting liquidity
- Multi-chain deployment: same pool design across multiple chains with cross-chain liquidity

### Smart Contract Specifications
- Core contracts: pool factory, router, fee collector, reward distributor
- Upgrade pattern: proxy contracts for upgradeability or immutable with migration
- Gas optimization: batch operations, minimal storage writes, efficient math libraries
- Composability: how other protocols can integrate and build on top of these pools
- Access control: admin functions, timelock, multisig requirements

### Risk Assessment
- Smart contract risk: audit requirements, bug bounty program, formal verification targets
- Economic risk: scenarios where the pool can be drained or manipulated
- Oracle risk: price manipulation through flash loans or multi-block attacks
- Concentration risk: single LP providing majority of liquidity
- Regulatory risk: token classification, securities law compliance considerations

## OUTPUT FORMAT
Complete liquidity pool design document with AMM model specification, fee architecture, incentive program, smart contract overview, and risk assessment.

## CONSTRAINTS
- All mathematical models must be clearly specified with formulas
- Gas efficiency is critical: design for minimal transaction costs on target chain
- Must be auditable: clean, well-documented smart contract architecture
- Incentive programs must be sustainable beyond initial token emissions
- Include MEV protection: mechanisms to protect LPs and traders from sandwich attacks
