How Aster Differs from Ordinary Perpetual DEXs
Aster is not an ordinary perpetual DEX, but a "liquidity abstraction layer". By introducing a "quoting system" and "price discovery mechanism", it allows users to trade perpetual contracts at prices close to the spot price. In contrast, ordinary perpetual DEXs rely on on-chain order books or constant-product AMMs, where prices are heavily influenced by liquidity depth.
Simply put, Aster aims to solve two core pain points of ordinary perpetual DEXs: high slippage (insufficient liquidity) and price deviation from spot (excessively high funding rates).
Prerequisite: Understanding the Basic Model of Ordinary Perpetual DEXs
Before comparing, let's clarify what ordinary perpetual DEXs (such as GMX, dYdX, Perpetual Protocol) are:
Order book model (e.g., dYdX): Matches orders off-chain, settles on-chain. Requires enough buy and sell orders, otherwise slippage is large.
AMM + oracle model (e.g., GMX): Users trade against a liquidity pool (GLP pool), price is quoted by an oracle (Chainlink), and slippage is determined by pool size.
Virtual AMM model (e.g., Perpetual Protocol): Uses a virtual liquidity curve to reduce slippage but relies on price oracles.
Common issues with ordinary perpetual DEXs: Slippage depends on pool depth or order book thickness; when liquidity is insufficient, large trades experience significant slippage. The funding rate mechanism often causes prices to deviate from spot, especially during market volatility.
Step 1: Understanding Aster's Core Mechanism — "Liquidity Abstraction Layer"
What to do: Understand why Aster is different from ordinary perpetual DEXs.
How to do it: Aster's core design is a combination of a "quoting system + liquidity pool" rather than a traditional order book or a single AMM pool:
Quoting System: Aster allows multiple market makers to submit quotes to the system. Users see the best quote, not the price of a single pool.
Multiple liquidity providers: Liquidity does not come from a single pool but from multiple market makers and professional traders, similar to the "request for quote" mechanism in traditional financial markets.
Price discovery mechanism: Through competition among multiple quotes, Aster's prices are closer to spot prices on major centralized exchanges (CEXs), rather than relying on a single oracle.
Core difference: Ordinary perpetual DEXs are "you vs the pool", while Aster is "you vs multiple quoters", with the pool as a backup liquidity source.
What qualifies as completion: You understand that Aster operates on a multi-quoter competition model, not a single AMM model.
Step 2: Comparing Slippage and Liquidity Between Aster and Ordinary Perpetual DEXs
What to do: Compare how the two models perform in actual trading.
How to do it: Use a table to compare key metrics:
| Comparison Dimension | Ordinary Perpetual DEXs (e.g., GMX, dYdX) | Aster |
|---|---|---|
| Liquidity source | Single pool (GLP) or order book | Multiple market makers + backup pool |
| Slippage control | Determined by pool depth; large orders experience noticeable slippage | Multi-quote competition; lower slippage for large orders |
| Price benchmark | Relies on oracle quotes (e.g., Chainlink) | Multiple quoters compete; closer to CEX spot prices |
| Funding rate | Fixed mechanism, may deviate from spot | Quoting system auto-adjusts; smaller spread |
| Trading depth | Limited by pool TVL | Market makers can provide additional depth |
What qualifies as completion: You recognize that Aster has advantages in slippage and price accuracy over ordinary perpetual DEXs, at the cost of relying on market maker participation.
Step 3: Understanding Aster's Market Maker Mechanism and Its Trade-offs
What to do: Understand where Aster's "better prices" come from, and what the trade-offs are.
How to do it: Aster's market maker mechanism resembles a "market maker network" in traditional finance, but with certain complexities:
Market makers provide quotes: Market makers submit two-way quotes (bid and ask) to the system; users see the best quote and can choose to trade.
Users can selectively trade: If the user deems the quote reasonable, they can execute immediately; if not, they can choose not to trade or wait for a better quote.
Market makers need to stake assets: Market makers must stake assets in the Aster system to ensure the validity of their quotes and their ability to fulfill trades.
Core advantage: Competition among market makers leads to better quotes and tighter spreads. Core trade-off: It relies on the continuous participation of market makers. If market makers withdraw or pause quoting, the trading experience will degrade.
What qualifies as completion: You understand that Aster's liquidity comes from multiple market makers, not just a single pool.
Common Misconceptions
Mistaking Aster for a fully decentralized order book DEX — Aster relies on market makers to provide quotes; its decentralization level is lower than purely AMM-based DEXs (like Uniswap), and it is closer to a "hybrid model".
Assuming Aster has completely solved the slippage problem — Although market makers can provide better quotes, during extreme market volatility (e.g., a 10% drop in 30 minutes), market makers may withdraw quotes, instantly draining liquidity.
Ignoring market maker risk: If major market makers in the Aster network exit simultaneously, liquidity could instantly drop, significantly worsening the trading experience.
Risk Reminder
Aster's "quoting system" depends on continuous quotes from market makers. If market makers withdraw due to market volatility or their own risk management, users may not be able to trade at the quoted price and will be forced to accept a worse price.
Aster's liquidity depth is directly tied to market maker participation, not bound to protocol TVL like GMX. Market maker exits can cause short-term liquidity drops.
As of July 2026, Aster is still in a relatively early stage; actual trading volume and user base may be limited, and the stability of the market maker network still needs to be verified.
How to Verify You've Understood Correctly
Open Aster's official website or trading interface and try to input a trade.
If the page shows "multiple quotes" or "best quote" options, your understanding is on the right track—it is indeed not a single-pool quote.
Compare the trading interfaces of Aster and GMX (or dYdX). Aster's quoting interface is more like a "request for quote" interface in traditional finance, while GMX's interface is closer to "trading directly at the pool price".
If you can understand the fundamental difference between Aster's "market maker competition quoting" model and ordinary DEXs' "pool quoting" model, you've grasped the core distinction. If you value decentralization and a completely trustless mechanism, ordinary perpetual DEXs may suit you better; if you prioritize price execution quality, Aster's model may have advantages.
