What is a crypto liquidity provider? How desks, brokers and exchanges choose one

A crypto liquidity provider is a firm that quotes prices and fills trades, so that another firm can buy or sell crypto-assets, stablecoins or FX in size without moving the price. This guide is about institutional providers: dealers, market makers and networks that supply liquidity to OTC desks, brokers and exchanges. It is not about DeFi liquidity pools, where holders deposit tokens into a smart contract and earn fees. Below: the types of provider, what each must supply, an eight-point checklist, and the questions to ask before you onboard.

Two meanings of “liquidity provider”

The phrase covers two different things, and most search results mix them up.

• DeFi liquidity provider. Someone who deposits a pair of tokens into an automated pool on a blockchain so others can swap against it. Anyone can do it, and the pool’s depth is whatever depositors put in.
• Institutional liquidity provider. A firm that streams or quotes prices to named clients, holds inventory or hedges in the market, and settles each trade with the client directly. Clients are onboarded through KYB and sanctions screening before they trade.

If you run an OTC desk, a brokerage or an exchange, you need the second kind. The rest of this guide uses “liquidity provider” in that sense.

The four types of institutional liquidity provider

The categories overlap, and one firm can act in more than one. This table describes the roles in general terms. It names no firms and gives no figures.

Type	What it does	Often suits	Main trade-off
Market maker	Quotes buy and sell prices continuously, on venues and directly to clients, and carries the inventory risk	Exchanges and brokers that need depth on a book or a streaming price	Quality depends on your connection and the pairs covered; quotes can widen in stressed markets
OTC desk or principal dealer	Quotes one firm price on request for a whole size and settles bilaterally	Treasuries, funds and desks moving blocks	Counterparty and settlement risk sit with one firm; it quotes only during its own hours
Liquidity network or aggregator	Connects to many venues and market makers and presents a combined price or routes your order	Brokers and exchanges that want one connection to many sources	An extra intermediary; the result is only as good as the sources behind it and how it routes
Prime broker	Bundles execution, custody, credit and financing for institutional clients	Funds and larger firms trading across venues on credit	Credit exposure and heavier onboarding; concentration risk if it is your only route

What a liquidity provider must supply

Whatever the label, a provider is doing five jobs. Check each one separately.

Pricing and depth. Does it quote the pairs you trade, at the sizes you trade, with prices you can act on? A firm price is held for a window and filled in full once you accept. An indicative price is only a guide. Depth matters most when markets are stressed, so ask how the provider behaves then.

Credit or prefunding. Every trade creates a window between agreeing a price and delivering both sides. Providers close that window in one of two ways. On a prefunded model, the client sends funds first. On a credit model, the provider extends a line and takes the client’s risk. The choice shapes your treasury: prefunding ties up cash, credit adds limits, collateral and diligence.

Settlement and fiat rails. A trade is only finished when money or tokens land where you can use them. Check which currencies the provider can settle, which bank rails it uses, which stablecoins and networks it supports, and what its cut-off times are. A provider with excellent prices but no route into your bank can cost you days.

Connectivity. Some providers stream prices into your system over an API or a FIX connection. Others quote by voice, chat or email. Neither is better in the abstract. An exchange or a broker with automated flow needs the first; a desk trading occasional blocks may be happy with the second.

Compliance. A provider that deals in crypto-assets for clients is generally required to be registered or authorised where it operates, and to run KYB, sanctions screening and Travel Rule checks on its counterparties. In Canada, FINTRAC says dealing in virtual currency, which includes exchange and transfer services, makes a business with a place of business in Canada a money services business, and foreign businesses that direct those services at people or entities in Canada, and provide them to clients in Canada, are covered too. Both must register. Check any provider on the regulator’s own public register, not on its own website.

How to choose: an eight-point checklist

1. Regulatory status. Find the provider on the register of each regulator that applies. Ask for the registration number and search it yourself. A registration is not an endorsement of the firm.
2. Coverage. Confirm the exact pairs, assets and sizes you need. Ask for the list in writing, because coverage changes.
3. Price quality. Compare an all-in quote with the mid-market rate at the moment you ask. Ask whether the price is firm, how long it holds, and whether fees, network costs or withdrawal charges come on top.
4. Credit and settlement model. Ask whether settlement is prefunded or on credit, who delivers first, how fast each leg settles, and what happens if one fails.
5. Fiat and stablecoin rails. Match the provider’s currencies, bank rails and stablecoin networks to the ones you already use. A transfer on the wrong network can be lost.
6. Connectivity. Decide how you will request and take prices, and whether the provider supports that method today.
7. Hours and resilience. Check when it quotes and who answers outside those hours. Many firms keep a second provider live so that one outage or one risk decision does not stop trading.
8. Onboarding and ongoing diligence. Ask which documents it needs, how long onboarding takes, and how it reviews you afterwards. Serious providers repeat checks for as long as the relationship lasts.

Questions to ask before you onboard

Put the same questions to every provider and keep the answers in writing.

• Is the price firm for my full size, and for how long?
• Do you trade against your own inventory, or do you pass my order to another firm?
• Is settlement prefunded or on credit, and which leg goes first?
• Which currencies, bank rails and stablecoin networks can you settle on?
• What are your quoting hours, and what is your minimum ticket?
• How do I request, accept and confirm a trade?
• What do you need from me at onboarding, and how often do you review me?
• If a leg fails or a payment is returned, who bears the loss, and how is it resolved?

Start with a small ticket to test execution and settlement before you route volume.

Liquidity provider vs market maker vs OTC desk

People use these terms loosely. The table separates them by what they describe.

Term	What it describes	How you usually deal with it
Liquidity provider	The broad role: any firm that lets you trade size at a fair price	Depends on the type of provider
Market maker	A way of providing liquidity: continuous two-way quotes, with the firm carrying inventory risk	Streaming prices, often on a venue or by direct connection
OTC desk	A client-facing service that quotes a firm price on request and settles bilaterally	Request for quote by voice, chat, email or a trading interface

A desk may buy from a market maker to fill your trade. A market maker may also run a desk. What matters is how the provider prices and settles the trade you want to make.

Settlement and fiat rails for liquidity takers

If you take liquidity, the trade is half the work. The other half is moving money in and out. Fiat has to reach the provider by a bank rail before it can deliver crypto or stablecoins, and the proceeds of a sale have to land in an account you can use. Stablecoins can shorten the on-chain leg, because they move in minutes at any hour, but the fiat leg still follows banking hours and cut-offs.

That makes your own accounts part of the choice. A firm that holds named accounts in the currencies it trades can fund a trade the same day. Our guide to stablecoin settlement for business explains how the on-chain leg works. Best crypto business accounts compares the account options, and what decides which providers will accept a crypto firm.

Where KwiikPay fits, and where it does not

What it is. KwiikPay runs an OTC desk and settlement service, and other desks, brokers and exchanges can onboard as its clients. See OTC desk liquidity and settlement for crypto firms. KwiikPay is not an exchange and not a DeFi pool.

What the desk quotes. FX, stablecoins and major crypto assets including BTC and ETH. The desk confirms the current list at onboarding. Tickets start at £250K. Spreads start from 8 bps inside £5M, depending on tier. Once you accept a firm price there is no slippage.

How it works.

• Prefunded only. Fiat and stablecoin sides must be in your KwiikPay account before you accept a price; for BTC and ETH, the desk confirms how your side is delivered before you trade. KwiikPay then delivers the other side. There are no credit lines.
• Voice, chat and email. Quotes and trades are by voice, chat and email with a dealer.
• Settlement. Usually same day.
• Hours (UTC, Monday to Friday). Singapore 00:00–09:00, London 07:00–19:00, New York 13:00–22:00.
• Stablecoin networks. Direct networks only: USDC and EURC on Ethereum, and USDT on Ethereum, BSC and Tron.
• Fiat side. Named GBP, EUR and USD accounts in your company’s name, held apart from KwiikPay’s own money. See business accounts.

Who can onboard. Desks, brokers and exchanges can be onboarded after KYB and enhanced due diligence; unlicensed or unregulated firms are not accepted. KwiikPay onboards companies incorporated in the European Economic Area, the United Kingdom, Gibraltar, Switzerland and Canada, where any authorisation their activity requires is current. Companies elsewhere are assessed individually, with no presumption of approval. Check your eligibility, then request an account. Account opening is by invitation, and the team replies within one business day.

What to ask us. Tell the desk the pair and size you need. Coverage and tiers are set out on the OTC desk page.
