Fixed and floating crypto quotes, explained

A fixed crypto quote locks an exchange rate for a stated time, while a floating quote uses the rate available when the trade executes. The difference affects how much you receive and who bears the risk of a price move while the trade is pending.

What does a fixed crypto quote lock in?

A fixed quote sets the rate for a defined amount and time window. If you accept it and the trade meets the provider’s conditions before it expires, the exchange rate should stay the same even if the market moves.

For example, a service might quote how much of one token you will get for a set amount of another. The displayed result can still depend on the quote’s terms: check whether it expires quickly, applies to the full amount, and includes network or service fees.

A fixed rate can make the result easier to plan around, but it is not a promise that every part of the transaction is fixed. A delayed transfer, a changed amount, or a missed expiry may require a new quote. If the route includes a bridge, a service that moves assets between networks, the manta bridge guide covers checks to make before assets move. The exchange quote and the bridge transfer are separate steps.

How does a floating crypto quote work?

A floating quote tracks the market rate and settles at execution, the point when the trade is carried out. The amount shown before you confirm is an estimate; it can change if the market price or available liquidity shifts before the trade completes.

Liquidity means how readily an asset can be bought or sold at a given price. In a thin market, a large order may fill at several prices. The average can differ from the rate shown when the order began. This price impact is often called slippage.

Some services set a slippage limit. It tells the trade how far the price can move before it stops instead of completing. A tighter limit gives more control over the price, but the order may fail if the market moves beyond it.

Which quote should you choose?

Choose based on whether price certainty or a live market rate matters more, and compare the final amount after fees. Before accepting either quote, check:

• How long the quote remains valid, or when the floating rate is set.
• Whether the amount shown is before or after service and network fees.
• What happens if the trade is delayed, partly filled, or rejected.
• For a floating quote, whether there is a slippage limit.

A fixed quote is usually easier to budget around when the terms are clear and you can complete the trade in time. A floating quote may suit someone who wants the rate at execution and accepts that the result can change. In both cases, compare the amount you expect to receive, not just the headline exchange rate.
