Market Maker
An entity (human, firm, or bot) that provides continuous two-sided quotes on an exchange to ensure trade execution for others.
Market Maker — A market maker is an entity — whether a firm, algorithm, or automated protocol — that provides continuous liquidity to a trading market by simultaneously placing buy and sell orders. Market makers profit from the bid-ask spread and are essential for maintaining orderly, tradeable markets on both centralized and decentralized exchanges.
What Is a Market Maker?
A market maker is any participant that provides liquidity by quoting both a buy price and a sell price for an asset. On centralized exchanges like Binance, professional firms such as professional market making firms, leading crypto firms, and institutional liquidity providers maintain order books for hundreds of tokens. On decentralized exchanges, anyone depositing tokens into a liquidity pool effectively acts as a market maker.
The spread between bid and ask prices is the market maker's primary revenue source. On highly liquid markets like BTC/USDT, spreads can be as tight as 0.01%. On smaller tokens, spreads of 1-5% are common.
How Market Makers Operate
Professional market makers use algorithms that continuously adjust bid and ask prices based on inventory, volatility, and order flow. A typical setup maintains hundreds of thousands of dollars in buy and sell orders spread across multiple price levels. As trades execute, the algorithm rebalances to maintain target inventory ratios.
On DEXs, market making is passive — liquidity providers deposit tokens and the AMM handles pricing automatically. Some projects use hybrid approaches, running active market-making bots alongside passive LP positions.
OpenLiquid's CEX market maker bridges these approaches by automating order management on centralized exchanges with configurable spread and depth parameters.
Why Market Makers Matter
Market makers are the foundation of liquid, functional trading markets. Without them, spreads widen, slippage increases, and traders leave. For new tokens, securing market-making coverage — whether through a professional firm, an automated tool, or sufficient DEX liquidity — is a prerequisite for sustained trading activity.
Exchange listing requirements often include market-making commitments. Most tier-2 and tier-3 centralized exchanges require projects to demonstrate that a market maker will maintain minimum spread and depth benchmarks before approving a listing.

Common questions about Market Maker in cryptocurrency and DeFi.
Market makers profit from the bid-ask spread — the difference between the price they buy at and the price they sell at. If a market maker buys at $0.99 and sells at $1.01, they earn $0.02 per unit. Over thousands of trades, these small margins compound into significant revenue.
On centralized exchanges, market makers actively manage order placement and pricing. On DEXs, liquidity providers passively deposit tokens into pools and the AMM sets prices. Both provide liquidity, but market makers exercise more control over their pricing strategy.
Any token that wants healthy trading activity benefits from market making. Tokens without market makers typically have wide spreads, high slippage, and low volume — all of which discourage trading and limit growth.
