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.

Adaptive Sigmoid Curve

A tanh-based curve keeps small trades efficient and increases impact for large trades.

Progressive Fees

Fees scale quadratically with trade size to protect pool liquidity.

Diamond Architecture

12 EIP-2535 facets share one AppStorage layout behind a single Diamond.

Core mechanics

Sigmoid price impact

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

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

Developer usage

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

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'
