# ARCHITECTURE.md — System Map
|
||
|
||
Compressed overview for AI agents. Read this first, drill into source for details.
|
||
|
||
## Contract Architecture
|
||
|
||
```
|
||
Kraiken.sol (ERC-20 token)
|
||
├── liquidityManager: address (set once, immutable after)
|
||
│ └── LiquidityManager.sol (ThreePositionStrategy)
|
||
│ ├── optimizer: Optimizer (private immutable ref)
|
||
│ ├── pool: IUniswapV3Pool
|
||
│ ├── kraiken: Kraiken
|
||
│ └── Positions: Floor, Anchor, Discovery
|
||
├── stakingPool: address
|
||
│ └── Stake.sol
|
||
│ ├── Staking positions with tax rates
|
||
│ ├── Snatch mechanics (competitive staking)
|
||
│ └── getPercentageStaked(), getAverageTaxRate()
|
||
└── feeDestination: address (protocol revenue)
|
||
|
||
Optimizer.sol (UUPS Upgradeable Proxy)
|
||
├── Reads: stake.getPercentageStaked(), stake.getAverageTaxRate()
|
||
├── Computes: sentiment → 4 liquidity params
|
||
├── Versions: Optimizer, OptimizerV2, OptimizerV3, OptimizerV3Push3
|
||
└── Admin: single address, set at initialize()
|
||
```
|
||
|
||
## Key Relationships
|
||
|
||
- **Kraiken → LiquidityManager**: set once via `setLiquidityManager()`, reverts if already set
|
||
- **LiquidityManager → Optimizer**: `private immutable` — baked into constructor, never changes
|
||
- **LiquidityManager → Kraiken**: exclusive minting/burning rights
|
||
- **Optimizer → Stake**: reads sentiment data (% staked, avg tax rate)
|
||
- **Optimizer upgrades**: UUPS proxy, admin-only `_authorizeUpgrade()`
|
||
|
||
## Three-Position Strategy
|
||
|
||
All managed by LiquidityManager via ThreePositionStrategy abstract:
|
||
|
||
| Position | Purpose | Behavior |
|
||
|----------|---------|----------|
|
||
| **Floor** | Safety net | Deep liquidity at VWAP-adjusted prices |
|
||
| **Anchor** | Price discovery | Near current price, 1-100% width |
|
||
| **Discovery** | Fee capture | Borders anchor, ~3x price range (11000 tick spacing) |
|
||
|
||
**Recenter** = atomic repositioning of all three positions. Triggered by anyone, automated by txnBot.
|
||
|
||
## Optimizer Parameters
|
||
|
||
`getLiquidityParams()` returns 4 values:
|
||
1. `capitalInefficiency` (0 to 1e18) — capital buffer level
|
||
2. `anchorShare` (0 to 1e18) — % allocated to anchor position
|
||
3. `anchorWidth` (ticks) — width of anchor position
|
||
4. `discoveryDepth` (0 to 1e18) — depth of discovery position
|
||
|
||
Sentiment calculation: `sentiment = f(averageTaxRate, percentageStaked)`
|
||
- High sentiment (bull) → wider discovery, aggressive fees
|
||
- Low sentiment (bear) → tight around floor, maximum protection
|
||
|
||
## Stack
|
||
|
||
### On-chain
|
||
- Solidity, Foundry toolchain
|
||
- Uniswap V3 for liquidity positions
|
||
- OpenZeppelin for UUPS proxy, Initializable
|
||
- Base L2 (deployment target)
|
||
|
||
### Indexer
|
||
- **Ponder** (`services/ponder/`) — indexes on-chain events
|
||
- Schema: `services/ponder/ponder.schema.ts`
|
||
- Stats table with 168-slot ring buffer (7d × 24h × 4 segments)
|
||
- Ring buffer segments: [ethReserve, minted, burned, tax] (slot 3 being changed to holderCount)
|
||
- GraphQL API at port 42069
|
||
|
||
### Landing Page
|
||
- Vue 3 + Vite (`landing/`)
|
||
- `@wagmi/vue` for wallet connection (WalletButton, WalletCard)
|
||
- `@tanstack/vue-query` — required peer dep for `@wagmi/vue`; provides TanStack Query context for Wagmi's reactive hooks
|
||
- `@harb/web3` shared composables (`useAccount`, `useConnect`, `useDisconnect`, `useTokenBalance`)
|
||
- Three variants: HomeView (default), HomeViewOffensive (degens), HomeViewMixed
|
||
- Docs section: HowItWorks, Tokenomics, Staking, LiquidityManagement, AIAgent, FAQ
|
||
- LiveStats component polls Ponder GraphQL every 30s
|
||
|
||
### Staking Web App
|
||
- Vue 3 (`web-app/`)
|
||
- Password-protected (multiple passwords in LoginView.vue)
|
||
- ProtocolStatsCard shows real-time protocol metrics
|
||
|
||
### Infrastructure
|
||
- Docker Compose on 8GB VPS
|
||
- Woodpecker CI at ci.niovi.voyage
|
||
- Codeberg repo: johba/harb (private)
|
||
- Container registry: registry.niovi.voyage
|
