In the fast-evolving world of digital assets, crypto exchanges serve as the backbone of trading activity. While they perform multiple roles—ranging from asset custody to price discovery—one of the most critical functions is ensuring liquidity. This article explores how exchanges maintain robust liquidity by collaborating with market makers, the mechanics behind their incentives, and why this relationship is vital for both retail and institutional traders.
Understanding Liquidity in Crypto Markets
Liquidity refers to how quickly and efficiently an asset can be bought or sold without causing a significant change in its price. In practical terms, high liquidity means tighter bid-ask spreads, deeper order books, and minimal slippage during trades.

The clearest indicator of liquidity is expected slippage—the difference between the current mid-market price and the actual average execution price. Two key factors influence slippage:
- Spread: The gap between the highest bid and the lowest ask.
- Depth: The volume of buy and sell orders stacked at various price levels.
For example, comparing the BTC/USDT order books on two major exchanges at the same moment reveals meaningful differences. On Binance, purchasing 18.57 BTC incurs approximately $2.97 in slippage (with zero taker fees), while buying 17.06 BTC on OKX results in about $6.29 in slippage (including a 0.02% taker fee). This suggests Binance offered superior BTC/USDT liquidity at that time.
High liquidity benefits all market participants:
- Retail traders enjoy faster executions and lower costs.
- Institutional investors can deploy large capital without disrupting prices.
- Exchanges attract more trading volume and user trust.
To achieve and sustain such liquidity, many exchanges partner with specialized entities known as market makers.
What Is a Market Maker?
A market maker is an individual or firm that provides continuous buy and sell quotes for a financial instrument, ensuring there’s always counterparty availability in the market. They do this by placing limit orders on both sides of the order book—buying at the bid and selling at the ask—profiting from the spread.
In traditional finance (TradFi), firms like Goldman Sachs, Citadel, and Two Sigma dominate market making in equities, ETFs, and forex. In the crypto space, the landscape includes:
- Traditional financial firms expanding into crypto: Jump Trading, Tower Research, DRW Cumberland.
- Crypto-native market makers: B2C2, Wintermute, and GSR.
Many exchanges, including Binance and Bitfinex, publish public leaderboards showcasing top market makers across spot, futures, perpetual swaps, and options markets. These rankings not only highlight performance but also foster competition among liquidity providers.
How Exchanges Attract Market Makers: The Market Maker Program
To incentivize consistent liquidity provision, crypto exchanges launch structured Market Maker Programs. These programs evaluate participants based on several performance metrics:
- Spread: How close their bid/ask prices are to the mid-market price.
- Depth: The size of their quoted orders.
- Uptime: Duration of active quoting on both sides of the book.
- Coverage: Number of trading pairs they support.
Alternatively, exchanges may assess performance simply by maker volume or maker participation rate—the proportion of total exchange volume generated by maker orders.
In return, exchanges offer compelling benefits:
- Technical advantages: Higher API rate limits and low-latency connectivity.
- Fee rebates: Reduced or negative maker fees (exchanges pay makers to provide liquidity).
- Financial support: Interest-free loans or credit lines to facilitate larger positions.
- Strategic incentives: Some platforms even grant equity or options to top-tier market makers.
For instance, Binance.US offers tiered rewards based on performance, including enhanced fee structures and dedicated technical support—making it attractive for professional liquidity providers.

Types of Market Maker Evaluation Models
Exchanges use different methodologies to assess and reward market makers, depending on their strategic goals.
1. Simple – Results-Driven Model
This model focuses solely on maker volume, measured either as:
- Absolute traded value,
- Percentage of total exchange volume,
- Or leaderboard ranking among all traders.
KuCoin’s Market Maker Incentive Plan operates under this model, offering bonuses tied directly to volume thresholds—a straightforward way to drive immediate liquidity.
2. Medium – Scorecard-Based Model
More sophisticated than volume-only models, this approach uses a weighted scorecard system. Exchanges assign points based on desired behaviors—such as maintaining tight spreads on specific pairs or sustaining uptime during volatile periods.
Binance.US and Binance’s COIN-M Futures Market Maker Program use this model, adjusting weights strategically to promote liquidity in newer or less-traded contracts.
3. Complex – Formula-Based Scoring System
The most advanced programs use algorithmic formulas that dynamically calculate rewards based on multiple variables like spread tightness, quote depth, and responsiveness.
dYdX’s first Liquidity Provider Rewards program (launched August 19, 2021) set a benchmark with its innovative formula. It was so effective that several other platforms quickly adopted similar models.
These tiered evaluation systems allow exchanges to fine-tune liquidity across different assets and market conditions—ensuring stability even during high volatility.
Why Liquidity Matters for Users
Strong liquidity isn’t just a back-end concern—it directly impacts user experience:
- Trades execute faster with minimal price deviation.
- Volatile assets become more tradable.
- Arbitrage opportunities shrink, leading to fairer pricing across platforms.
For institutions evaluating where to trade or list new tokens, liquidity is often a deciding factor. A liquid market ensures smoother entry and exit, reduces execution risk, and enhances overall confidence in the platform.
Frequently Asked Questions (FAQ)
Q: Can anyone become a market maker on a crypto exchange?
A: Technically yes, but formal Market Maker Programs typically require proven track records, significant capital, and advanced trading infrastructure. Most participants are professional firms rather than individuals.
Q: Do market makers manipulate prices?
A: Reputable market makers operate within strict guidelines set by exchanges. Their role is to stabilize prices—not manipulate them. They profit from spreads, not directional bets, so they aim to remain neutral.
Q: Are market maker programs only for large exchanges?
A: No. Even emerging exchanges run such programs to bootstrap liquidity for new trading pairs. However, the scale and rewards differ significantly compared to major platforms.
Q: How do I tell if a trading pair is liquid?
A: Check the order book depth, bid-ask spread, and recent trade history. Tight spreads and deep order books indicate strong liquidity. Tools like tradingview or exchange analytics dashboards can help assess this.
Q: Is negative fee common for market makers?
A: Yes. Many exchanges offer negative taker fees (rebates) to makers—meaning they pay market makers to provide liquidity. This is standard practice on top-tier platforms.
