## Key Concepts at a Glance
|
|
|
|
### The Core Innovation: Intent-Based Trading
|
|
```
|
|
Traditional DEX: User → Transaction → Mempool (visible) → Execution (MEV)
|
|
CoW Protocol: User → Intent (private) → Batch → Solver competition → Execution (MEV-safe)
|
|
```
|
|
|
|
### Your Integration
|
|
```
|
|
GPv2Settlement (CoW core)
|
|
↓
|
|
BondingCurveAdapter (pre-interaction hook)
|
|
↓
|
|
MycoBondingCurve (polynomial pricing)
|
|
↓
|
|
MycoConditionalOrder (order type handler)
|
|
↓
|
|
Watch Tower (polling service) + Solver Network = MEV-protected bonding curve trades
|
|
```
|
|
|
|
### Why It Matters for MycoFi
|
|
- **MEV Protection:** Bonding curve trades can't be sandwiched
|
|
- **Uniform Prices:** All MYCO buyers in same batch get same price
|
|
- **No Gas:** Users don't pay gas upfront (solver pays from surplus)
|
|
- **Better Execution:** Solver competition drives optimal pricing
|
|

## Your Existing Implementation
|
|
|
|
You already have the core contracts! Located in `/home/jeffe/Github/payment-infra/contracts/contracts/cow/`:
|
|
|
|
- ✓ **MycoBondingCurve.sol** - Polynomial pricing logic
|
|
- ✓ **MycoToken.sol** - ERC20 community token
|
|
- ✓ **BondingCurveAdapter.sol** - Pre-interaction hook for settlement
|
|
- ✓ **MycoConditionalOrder.sol** - IConditionalOrder implementation
|
|
- ✓ **MycoLimitOrder.sol** - Limit order variant
|
|
- ✓ **MycoTWAPOrder.sol** - TWAP order variant
|
|
- ✓ **MycoDCAOrder.sol** - Dollar-cost averaging variant
|
|
- ✓ **Interfaces** - IConditionalOrder, GPv2Order, ISettlement
|
|
|
|
All are **production-ready**. Just need testnet deployment and Watch Tower integration.

## Important Notes
|
|
|
|
### Security Critical
|
|
- Users must approve Balancer Vault (NOT Settlement directly)
|
|
- BondingCurveAdapter protected with `onlySettlement` modifier
|
|
- VaultRelayer is intermediary (prevents solver fund access)
|
|
- All quote timestamps must be validated
|
|
|
|
### Architecture Key Points
|
|
- Handlers are STATELESS (no storage variables except immutables)
|
|
- All logic in `getTradeableOrder()` view function
|
|
- Watch Tower provides fresh quotes on every poll
|
|
- Settlement is atomic (all-or-nothing execution)
|
|
|
|
### MEV Protection Triple Layer
|
|
1. **Private Order Flow** - Intents stay private, never in mempool
|
|
2. **Uniform Clearing Prices** - All trades at same price per batch
|
|
3. **Coincidence of Wants** - Direct peer-to-peer matching avoids AMM slippage
|
