⚡ PercolatePerps

Next-Generation Perpetual Futures DEX on Solana
Built for speed, designed for scale, optimized for capital efficiency.

🚀 Why PercolatePerps?

PercolatePerps reimagines perpetual futures trading on Solana through a revolutionary sharded architecture. Unlike monolithic DEXes that bottle-neck as they scale, PercolatePerps grows horizontally—each new market strengthens the ecosystem without impacting existing ones.

Core Innovation:

🔥 Sharded Execution - Independent LP-operated "slabs" run in parallel
💰 Portfolio Margin - Cross-collateralize positions across all markets
⚡ Sub-millisecond Matching - High-frequency trading ready
🛡️ MEV Protection - Built-in anti-toxicity mechanisms
🎯 VWAP Guarantees - Two-phase reserve-commit execution

📊 Performance Metrics

Metric	Specification
Latency	< 0.5ms per commit
Throughput	50k+ orders/sec per slab
Memory	10 MB per slab (strict)
Precision	6 decimals (microsats)
Capital Efficiency	~5% vs monolithic baseline

Router Program

ID: RoutR1VdCpHqj89WEMJhb6TkGT9cPfr1rVjhM3e2YQr

The brains of the operation. Routes orders, manages collateral, and aggregates risk across all markets.

Key Components:

Vault → Holds user collateral (USDC, SOL, etc.)
Portfolio → Tracks net exposure across all positions
Escrow → Per-slab collateral allocations
Capability → Time-limited debit tokens (2min TTL)

Slab Program

ID: SLabZ6PsDLh2X6HzEoqxFDMqCVcJXDKCNEYuPzUvGPk

The execution engines. Each slab is a complete perpetual futures exchange in 10 MB.

Key Components:

SlabHeader → Config and parameters
Instrument → Contract specifications
Order → Full order book with reservations
Position → User positions with PnL tracking
Trade → Execution history (ring buffer)

🎯 Trading Flow

Market Order (Simple)

1. User submits order → Router
2. Router checks margin
3. Slab executes against book
4. Position updated, PnL settled

Aggregated Order (Advanced)

1. Router reserves liquidity across multiple slabs
   └─> Gets VWAP quotes from BTC, ETH, SOL slabs
2. Router selects optimal execution path
3. Commits atomic multi-slab execution
   └─> All succeed or all revert
4. Portfolio margin updated globally

🛡️ Security Features

Capability-Based Authorization

Slabs can't directly access user funds. Instead:

Router issues time-limited "capability tokens"
Scoped to specific (user, slab, asset) triplets
2-minute maximum lifetime
Nonce-based replay protection

Cap {
    user: Pubkey,
    slab: Pubkey,
    mint: Pubkey,
    amount_max: u128,
    remaining: u128,
    expiry: UnixTimestamp,
    nonce: u64,
}

Anti-MEV Mechanisms

Batch Windows - Discrete 50-100ms matching epochs
Pending Queues - Makers wait one epoch before going live
JIT Penalties - No rebates for just-in-time liquidity
Kill Bands - Reject if mark price moved >X%
Freeze Levels - Circuit breakers during volatility
Roundtrip Guards - Detect and tax sandwich attempts

💾 Memory Architecture

Each slab operates in a fixed 10 MB account with zero allocations:

struct SlabState {
    header: SlabHeader,              // 512 bytes
    accounts: Pool<Account, 5000>,   // ~1.2 MB
    instruments: [Instrument; 32],   // ~64 KB
    orders: Pool<Order, 30000>,      // ~3.8 MB
    positions: Pool<Position, 30000>, // ~2.4 MB
    reservations: Pool<Reservation, 4000>, // ~512 KB
    slices: Pool<Slice, 16000>,      // ~384 KB
    trades: RingBuffer<Trade, 10000>, // ~800 KB
    aggressor_log: Pool<Entry, 4000>, // ~256 KB
}
// Total: ~9.9 MB (within 10 MB limit)

Why it matters:

Predictable performance (no GC pauses)
Provably fits in Solana account limits
O(1) allocation/deallocation
Zero fragmentation

# Run all tests
cargo test

# Test specific package
cargo test --package percolateperps-router

Integration Tests (Coming Soon)

Using Surfpool for realistic on-chain testing:

#[surfpool::test]
async fn test_cross_slab_arbitrage() {
    // Setup: BTC trading at different prices on two slabs
    let slab_a = deploy_slab("BTC-A", initial_price: 50000).await;
    let slab_b = deploy_slab("BTC-B", initial_price: 50100).await;
    
    // Execute: Buy on A, sell on B
    router.atomic_execute([
        buy(slab_a, qty: 10),
        sell(slab_b, qty: 10),
    ]).await?;
    
    // Verify: Profit captured, no margin increase
    assert_eq!(portfolio.realized_pnl, 1000); // 10 * $100 spread
    assert_eq!(portfolio.margin_used, 0);     // Hedged position
}

📚 Key Concepts

Portfolio Margin

Traditional CEXes: Each position margined independently
❌ BTC long = 5% margin, ETH long = 5% margin → 10% total

PercolatePerps: Net exposure across all positions
✅ BTC long + ETH short = ~3% margin (if correlated)

Result: 2-3x better capital efficiency

Reserve-Commit Flow

Problem: On-chain aggregators can't atomically lock liquidity across multiple DEXes.

Solution: Two-phase execution

Reserve - Lock liquidity, get VWAP quote (doesn't execute)
Commit - Execute at reserved prices (guaranteed)

Benefits:

Aggregators know exact fill price before executing
No slippage between quote and execution
MEV protection (reserved liquidity is invisible)

Sharded Execution

Traditional DEX: All markets share one order book → congestion
PercolatePerps: Each market has its own slab → parallel execution

Scalability:

Linear throughput scaling (add more slabs = more capacity)
No cross-market interference
LP autonomy (set your own fees/params)

🎨 Design Principles

Security First - Slabs can never directly access Router vaults
Zero Allocations - All memory pre-allocated at initialization
Deterministic - Same inputs always produce same outputs
Auditable - Clear invariants with property-based tests
MEV-Resistant - Multiple layers of anti-toxicity protection
