# HyperPax DEX

> Network-operated Adaptive Sigmoid AMM with Diamond facets, progressive fees, oracle-pegged pools, and typed SDK support

## Overview

HyperPax DEX is the public protocol name for the network-operated v5-ASAMM system. It is an Adaptive Sigmoid Automated Market Maker built for Paxeer Network chain ID `125`.

  <Card title="Adaptive Sigmoid Curve" icon="wave-square">
    A tanh-based curve keeps small trades efficient and increases impact for large trades.
  </Card>

  <Card title="Progressive Fees" icon="chart-line">
    Fees scale quadratically with trade size to protect pool liquidity.
  </Card>

  <Card title="Diamond Architecture" icon="gem">
    12 EIP-2535 facets share one AppStorage layout behind a single Diamond.

## Core mechanics

### Sigmoid price impact

```text theme={null}
P(x) = P_mid * (1 + k * tanh(a * x / L))
```

| Parameter | Meaning                                   |
| --------- | ----------------------------------------- |
| `P_mid`   | Current mid-price from reserves or oracle |
| `k`       | Maximum price deviation factor            |
| `a`       | Curve steepness                           |
| `x`       | Signed trade size                         |
| `L`       | Pool liquidity                            |

### Progressive fee

```text theme={null}
fee(x) = baseFee + impactFee * (x / L)^2
```

Fees are distributed as:

| Recipient          | Share |
| ------------------ | ----: |
| LPs                | `70%` |
| Protocol treasury  | `20%` |
| Trader rebate pool | `10%` |

## Facets

| Group              | Facets                                                   |
| ------------------ | -------------------------------------------------------- |
| Core               | `DiamondCutFacet`, `DiamondLoupeFacet`, `OwnershipFacet` |
| Pool operations    | `PoolFacet`, `LiquidityFacet`, `SwapFacet`               |
| Pricing and fees   | `FeeFacet`, `OracleFacet`, `OraclePegFacet`              |
| Orders and rewards | `OrderFacet`, `RewardFacet`, `FlashLoanFacet`            |

## Developer usage

Use the Router for swaps and liquidity operations unless you need lower-level Diamond facet calls.

```typescript theme={null}
import { createPublicClient, http } from 'viem'
import { hyperpaxeer } from './chains'

const client = createPublicClient({
  chain: hyperpaxeer,
  transport: http('https://public-rpc.paxeer.app/rpc'),
})

const router = '0x635aC031f7d26035FCc8b138b0835fec0cf6b8AA'
```
