How does the maker in crypto work?

Last Updated

Key Takeaways

Definition: A "Maker" is a trader who provides liquidity to an exchange by placing orders that do not execute immediately.
The Mechanism: Makers use limit orders to add depth to the order book, waiting for a "Taker" to match their price.
Incentives: Exchanges typically charge makers lower fees (or even offer rebates) to encourage them to provide liquidity.
Market Impact: Makers stabilize the market by narrowing the bid-ask spread and reducing price volatility.

At its core, a Maker is a liquidity provider. When you place an order that is not immediately matched by an existing order on the "order book," you are "making" a market. You are effectively telling the exchange, "I am willing to buy/sell this asset at this specific price," and then waiting for someone else to take you up on that offer.

The Role of the Order Book

Every centralized exchange (CEX) uses an order book—a real-time ledger of buy and sell interest.

Bids: Orders to buy.
Asks: Orders to sell.

When a maker places a limit order, it sits in this book. This "resting" order provides options for other traders, ensuring that when someone wants to trade immediately, there is an available counterparty.

The process of being a maker is defined by the type of order you use and how it interacts with the current market price.

Using Limit Orders

To act as a maker, you must use a limit order. Unlike a market order (which buys or sells at whatever the current price is), a limit order specifies a maximum buy price or a minimum sell price.

The Bid-Ask Spread

Makers profit and stabilize the market through the bid-ask spread. This is the gap between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. By placing orders close to the "mid-price," makers keep this gap narrow, making it cheaper for everyone else to trade.

"Post-Only" Orders

Many professional traders use a "Post-Only" setting. This ensures that their order is only placed if it can act as a maker. If the market moves so fast that the order would execute immediately (turning the trader into a taker), the system cancels the order instead to avoid higher fees.

Liquidity is the lifeblood of a crypto exchange. An exchange with high liquidity allows users to trade large amounts without causing massive price swings (known as slippage).

Because makers provide this valuable service, exchanges incentivize them with a Maker-Taker Fee Model:

Maker Fees: Usually range from 0.00% to 0.10%. Some high-volume institutional makers even receive "rebates" (getting paid to trade).
Taker Fees: Typically higher, ranging from 0.05% to 0.25%, because they remove liquidity from the book for the convenience of immediate execution.

Market Role	Provides Liquidity	Consumes Liquidity

The "maker" in crypto is the engine of market stability. By placing limit orders that stay on the order book, makers ensure there is always a "shelf" of assets for others to buy or sell. In exchange for their patience and the risk of the market moving against them, makers enjoy lower trading fees and play a vital role in the health of the crypto ecosystem.

Can a limit order ever be a taker order?

Yes. If you place a limit buy order at a price that is higher than the current lowest sell offer, it will execute immediately. In this case, you are removing liquidity and will be charged a taker fee.

Is it better to be a maker or a taker?

It depends on your goal. If you want the lowest fees and aren't in a rush, being a maker is better. If you need to exit a position immediately due to high volatility, being a taker is necessary despite the higher cost.

How do automated market makers (AMMs) differ?

In Decentralized Finance (DeFi), AMMs like Uniswap don't use order books. Instead, they use "Liquidity Pools" where the "maker" is anyone who deposits tokens into the pool to earn a share of the trading fees.

What is "slippage" for makers?

Makers generally don't experience slippage because their orders only fill at the specific price they set. Takers, however, often face slippage when they "eat" through multiple layers of the order book to fill a large order.
