Merkle Trade

Merkle Trade is Aptos’s primary perpetuals DEX — offering leveraged trading on crypto, forex, and commodity markets through a pool-based counterparty model where MKL-staked liquidity providers act as the house against trader positions, with Aptos’s Move VM enabling fast settlement and low-cost order execution for active traders.

Overview

Merkle Trade launched on Aptos mainnet in 2023 as the ecosystem’s dedicated leverage trading venue, occupying the perps DEX role that Adrena fills on Solana and BlueFin fills on Sui. Merkle’s standout features: offering non-crypto perpetuals markets (forex, gold, oil) in addition to standard BTC/ETH/APT crypto perps — making it the most diversified on-chain perps venue in the Aptos ecosystem. The pool-based counterparty model (similar to GMX’s GLP) is well-suited to Aptos’s current liquidity levels, as it doesn’t require deep two-sided orderbook depth to launch new markets.

Pool Model: MKL Liquidity Providers

The model works as follows.

Merkle LP Pool

  • Liquidity providers deposit USDC into the Merkle LP pool
  • LP pool acts as counterparty to all trader positions
  • When traders lose → LP pool gains; when traders win → LP pool loses
  • LPs earn: position opening/closing fees + hourly borrow fees from traders

Counterparty Risk Management

Protocol protections for LP pool:

  • Max open interest caps — total trader long/short OI limited as % of pool size
  • OI imbalance fees — when one side is heavily dominant (most traders long), the imbalance creates additional borrow fee pressure
  • Position size limits — per-trade maximum position sizes
  • Volatility-based dynamic spreads — in high-volatility periods, spreads widen to protect LP pool

Supported Markets

Merkle Trade offers one of the broadest market selections among on-chain perps:

Crypto Markets:

  • BTC-PERP
  • ETH-PERP
  • APT-PERP
  • SOL-PERP
  • Additional altcoin perps

Traditional Markets:

  • Forex: EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD
  • Commodities: XAU/USD (Gold), XAG/USD (Silver)
  • Indices: Some stock index exposure (via synthetic token perps)

The forex and commodity markets are a major differentiator — most DeFi perps (GMX, Adrena, Bluefin) focus exclusively on crypto assets.

Trading Features

  • Leverage: Up to 150x on forex, up to 100x on BTC/ETH, up to 50x on alts
  • Market orders — instant fill at oracle price
  • Limit orders — trigger at target price via keeper network
  • Take profit / Stop loss — conditional orders executed by keepers
  • Mark Price: Pyth oracle price (prevents market manipulation)
  • Liquidation: Maintenance margin monitoring; automatic liquidation when equity falls below threshold

MKL Token

MKL is Merkle Trade’s governance and incentive token:

  • Staking — stake MKL → earn share of protocol trading fees (paid in USDC)
  • Governance — MKL holders vote on new market listings, fee rates, LP pool parameters
  • Trading rebates — staked MKL provides fee discounts on trading costs
  • Liquidity mining — MKL emissions to LP depositors and traders

Pyth Oracle Integration

All Merkle Trade market prices sourced from Pyth Network:

  • Sub-second price update capability (critical for forex trading where rates change rapidly)
  • Confidence band used for liquidation safety margin (prevents cascade liquidations from oracle noise)
  • Custom price lag settings per market (forex markets accessible during trading hours only)
