OTC desk development for crypto, built for size
Request for quote, settlement windows, counterparty limits and the approval trail an auditor asks for. The venue shape that serves ten clients, not ten thousand users.
An OTC desk is the opposite of a retail exchange. A handful of counterparties, large tickets, relationships instead of traffic, and a price agreed rather than matched.
How the flow differs
1. A client requests a quote for a size that would move a public book.
2. A dealer, or a pricing rule, responds with a firm price and a validity window.
3. The client accepts, rejects, or counters.
4. Settlement happens on agreed terms: same day, next day, part now and part later.
Nothing about that resembles an order book, which is why building an OTC desk on top of one produces a worse version of both.
What the build contains
- An RFQ flow with quote validity, counters and an expiry that is enforced rather than displayed
- A dealer screen: open requests, positions, exposure per counterparty, the ability to price manually or from a rule
- Counterparty records: limits per client, settlement terms, who may trade on their behalf
- Settlement tracking: instructed, partially settled, settled, with evidence attached
- An approval trail, because every quote, amendment and settlement will be examined eventually
- Statements per counterparty and per period
The parts people underestimate
Credit. If you settle before receiving, you have extended credit, and that is a risk decision with limits, not a convenience. The system must enforce the limit rather than remind someone of it.
Who is allowed to trade. A corporate client has several people and not all of them may commit the company. That is a permissions model, not a note in a file.
Amendments. Trades get corrected. An amendment is a new record referencing the old one, never an edit, or your audit trail is fiction.
On a retail venue the audit trail is good practice. On a desk it is the product, because every dispute is resolved from it.
Does it need an exchange underneath
Not necessarily, and that is the useful part. An OTC desk can run against your own inventory and external venues without a matching engine at all. If you also run a retail exchange, the desk can share accounts, custody and the console, and keep its own flow.
Pricing is per project, like P2P and derivatives, because the variable is your settlement and credit policy rather than the screens.
Questions
What is a crypto OTC desk
A venue where large trades are negotiated directly rather than matched on a public book. Clients request a quote, a dealer prices it, and settlement happens on agreed terms.
How is an OTC desk different from an exchange
There is no order book and no anonymous matching. Price is quoted, counterparties are known, limits are per client, and settlement is a tracked process rather than instant.
Do I need a matching engine for an OTC desk
No. Quotes come from inventory, a pricing rule or an external venue. That makes a desk a smaller technical build than a retail exchange, with more policy in it.
What is RFQ
Request for quote: a client asks for a price on a specific size, you respond with a firm quote valid for a short window, and they accept or decline within it.
How do counterparty limits work
Each client has a maximum exposure and settlement terms. The system enforces them at quote time rather than flagging them afterwards, which is what makes them real.
Can a desk run alongside a retail exchange
Yes. They can share accounts, custody and the console while keeping separate flows, which is the usual arrangement when a venue grows into serving larger clients.
