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))
ParameterMeaning
P_midCurrent mid-price from reserves or oracle
kMaximum price deviation factor
aCurve steepness
xSigned trade size
LPool liquidity

​
Progressive fee

fee(x) = baseFee + impactFee * (x / L)^2
Fees are distributed as:
RecipientShare
LPs70%
Protocol treasury20%
Trader rebate pool10%

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'
