Maker (Exchange)
A trader who places a limit order that adds liquidity to the order book and waits for another party to fill it.
Maker (Exchange) — A maker is a trader who places a limit order that adds liquidity to an exchange's order book by setting a price that does not immediately match existing orders. Maker orders rest on the book until another trader fills them, and most exchanges reward makers with lower fees (or even rebates) because they increase market depth and improve trading conditions.
How Makers Work
When a trader places a limit order at a price that does not immediately execute — such as a buy order below the current ask or a sell order above the current bid — that order becomes a maker order. It "makes" liquidity by adding to the order book, giving other traders more options for executing their trades. The order sits on the book until a matching taker order fills it, or the maker cancels it.
For example, if ETH is trading at $3,200 with the best ask at $3,200.50 and a trader places a buy order at $3,198, that order adds liquidity to the bid side of the book. It will only execute when a seller agrees to sell at $3,198 or the market drops to that level. Until then, it deepens the order book and narrows the effective spread available to other participants.
On AMM-based DEXs, liquidity providers (LPs) serve the same economic function as makers. By depositing tokens into a liquidity pool, LPs make liquidity available for other traders to swap against. They earn trading fees as compensation, analogous to the fee discounts and rebates that order-book makers receive on centralized exchanges.
Why Makers Matter
Makers are essential for healthy markets. Without maker orders, there would be no resting liquidity in the order book, and every trade would execute against the next available order at potentially extreme prices. High maker activity results in tight bid-ask spreads, deep order books, and low slippage for large trades. This is why exchanges incentivize maker activity through lower fees — typically 0.01% to 0.10% — compared to higher taker fees.
Professional market makers are specialized firms that place large volumes of maker orders on both sides of the book, profiting from the spread while providing continuous liquidity. Their activity is responsible for much of the liquidity on major trading pairs and is a key factor that exchanges consider when evaluating listing applications.
Real-World Example
A trader on Binance places a limit buy for 5 BTC at $64,500 when the current price is $65,000. This order rests on the bid side of the BTC/USDT order book as a maker order. Binance charges a 0.02% maker fee for this trade tier. Three hours later, BTC drops to $64,500 and a market seller fills the order. The trader pays $64.50 in fees on the $322,500 trade. If instead the trader had placed a market buy at $65,000 (a taker order), the fee would have been 0.04%, or $130 — double the maker fee. The $65.50 fee difference adds up significantly for active traders executing hundreds of trades per month.

Common questions about Maker (Exchange) in cryptocurrency and DeFi.
A maker places an order that adds liquidity to the order book (it doesn't immediately fill). A taker places an order that removes liquidity by matching against a resting maker order. Limit orders set away from the current price are maker orders; market orders and limit orders at the current price are taker orders.
On most centralized exchanges, yes. Maker fees are typically 30-60% lower than taker fees. Some exchanges even offer negative maker fees (rebates), paying makers a small amount for each filled order. On DEXs, all swappers pay the same fee rate, but liquidity providers (the maker equivalent) earn a share of those fees.
Yes. If a limit buy order is placed at or above the current ask price, it immediately matches with a resting sell order and executes as a taker order. A limit order only becomes a maker order if its price does not match any existing orders on the opposite side of the book.
