    Core Trading Mechanism

    Aster uses a central limit order book (CLOB) model for trade execution, similar to traditional financial exchanges. This is fundamentally different from AMM-based DEXs like GMX or Uniswap, which rely on liquidity pools and algorithmic pricing.

    In Aster's CLOB model, traders submit buy and sell orders at specific prices. The matching engine pairs compatible orders using price-time priority: orders at the best price are filled first, and among orders at the same price, the earliest order takes precedence. This results in transparent, fair price discovery driven entirely by real supply and demand.

    CLOB vs AMM: How They Differ

    CLOB (Aster's Approach)

    • Discrete limit and market orders on an order book
    • Price discovery from real buyer/seller interaction
    • Tight spreads, especially on liquid pairs
    • Advanced order types: limit, stop-loss, take-profit
    • Off-chain matching for speed, on-chain settlement for security

    AMM (e.g., GMX, Uniswap)

    • Trade against a liquidity pool, not individual counterparties
    • Price set by algorithm (constant product, oracle, etc.)
    • Higher slippage on large orders
    • Simpler UX, no need to set specific prices
    • Fully on-chain execution (slower but fully transparent)

    Blockchain & Network

    Aster is built on BNB Smart Chain (BSC), one of the highest-throughput EVM-compatible blockchains. BSC was chosen for its combination of speed, low cost, and broad ecosystem compatibility.

    Why BNB Smart Chain?

    • Speed: ~3-second block times mean trade confirmations are near-instant, critical for a perpetual futures exchange where price movements are rapid.
    • Low gas costs: BSC transactions typically cost under $0.10, making it economical to open, modify, and close positions frequently without gas eating into profits.
    • EVM compatibility: Developers can leverage the vast Ethereum tooling ecosystem (Solidity, Hardhat, etc.), and users can connect with any EVM wallet like MetaMask.
    • Future own chain: Aster has announced plans to launch its own dedicated blockchain in the future, which would give the team full control over throughput, fee structure, and consensus parameters.

    Fee & Gas Model

    Trading Fees

    Maker fee0.01%
    Taker fee0.035%
    Volume discountsAvailable

    Maker orders add liquidity to the book (limit orders that rest). Taker orders remove liquidity (market orders or crossing limit orders). Higher trading volume unlocks lower fee tiers.

    Gas Costs

    Gas tokenBNB
    Typical cost< $0.10
    Recommended buffer$2 - $5 in BNB

    Gas is required for on-chain operations: depositing collateral, approving tokens, and withdrawing funds. Keep a small BNB buffer in your wallet to avoid failed transactions.

    Volume-Based Fee Discounts

    Aster offers tiered fee reductions based on your 30-day trailing trading volume. As your volume increases, both maker and taker fees decrease. ASTER token holders may receive additional fee reductions. Check the ASTER Token guide for details on token-based fee benefits.

    Settlement & Clearing

    Margin System

    Aster operates a cross-margin and isolated-margin system. Traders deposit USDC or USDT as collateral into on-chain smart contracts. This collateral backs your open positions and determines your maximum position size based on chosen leverage.

    • Cross margin: All positions share a single collateral pool. Gains from one position can offset losses in another.
    • Isolated margin: Each position has its own dedicated collateral. Liquidation of one position does not affect others.

    Liquidation Engine

    When a position's margin ratio falls below the maintenance margin threshold, the liquidation engine automatically closes the position to prevent further losses. The engine attempts to close positions at the best available market price.

    If a liquidated position cannot be closed at the bankruptcy price (the price at which the trader's margin reaches zero), the shortfall is covered by the insurance fund.

    Insurance Fund

    The insurance fund is a reserve pool funded by a portion of liquidation penalties and trading fees. Its purpose is to absorb losses from bankrupt positions so that profitable traders are paid in full.

    In extreme market conditions, if the insurance fund is insufficient, Aster may trigger auto-deleveraging (ADL), where the most profitable opposing positions are partially closed to cover the deficit. This is a standard safety mechanism across perpetual futures platforms.

    Ecosystem Overview

    Aster is more than just a trading platform. Here is what makes up the broader ecosystem.

    Perpetual DEX Trading

    Trade perpetual futures on major crypto pairs with up to 300x leverage. CLOB execution with deep liquidity, advanced order types, and real-time price feeds.

    Token Staking

    Stake ASTER tokens to earn a share of platform revenue and unlock fee discounts. Staking aligns token holder incentives with platform growth.

    Governance

    ASTER token holders can participate in governance decisions affecting the protocol's future direction, fee parameters, and feature prioritization.

    Own Chain (Upcoming)

    Aster has announced plans to launch its own dedicated blockchain, giving the team full control over network performance, fee economics, and consensus design -- similar to the path taken by Hyperliquid and dYdX.
