If your business needs to move a large amount of crypto — converting treasury, settling a big trade, or on/off-ramping size — a public exchange is often the wrong tool. Place a large order on an order book and you move the market against yourself: the price slips as your order fills, and everyone watching can see it happen. Over-the-counter (OTC) trading solves this by letting you execute directly with a dealing desk at a single agreed price.
This guide is for the business or desk doing the trading — treasuries, trading firms, payment companies and funds executing size — not retail traders.
What OTC trading actually is
OTC trading means transacting directly with a counterparty (the desk) rather than on a public exchange. Instead of submitting an order that fills against whatever liquidity is on the book, you ask the desk for a price on a specific size. The desk quotes a firm rate for the full amount; if you accept, the trade is done at that rate and settled bilaterally.
The key difference from an exchange is price certainty for size. On an exchange, a large order eats through successive price levels — the deeper your order, the worse the average price. An OTC desk prices the whole block at once, sourcing liquidity across multiple venues so it can absorb size without the market impact you'd cause yourself.
Why businesses use a desk
- Deep liquidity. Execute large trades without moving the market, because the desk aggregates liquidity from many venues rather than relying on a single book.
- Price certainty. You see a firm price for the full size before committing, minimising slippage.
- Discretion. Large trades aren't broadcast to the market as they fill.
- Operational efficiency. Settlement is streamlined in crypto or fiat, with one counterparty rather than fragmented fills across exchanges.
- Compliance. Trading within a licensed, regulated framework keeps the activity clean for your auditors and banking relationships.
How an OTC trade works, step by step
- Onboard. The desk approves your account after KYC/AML and corporate documents — done once, up front.
- Set up. Whitelist your wallets and bank accounts so settlement can only go to known destinations.
- Fund. Deposit fiat or crypto to your designated accounts.
- Request a price. Tell the desk the asset, direction and size; receive a firm quote.
- Execute. Accept the quote and the trade is locked at that rate.
- Settle. Funds and assets are exchanged on the agreed timeline — often same day — to your whitelisted wallet or bank account.
A worked example
Suppose a payment company has accumulated a large stablecoin balance from settlement activity and needs to convert it to fiat to fund operations. Sweeping that size across exchange order books would slip the rate and signal the move to the market. Instead, the company asks an OTC desk for a price on the full amount. The desk quotes a single firm rate; the company accepts; the fiat settles to its bank account the same day at the agreed price — no slippage, no market impact, one clean settlement.
What to check before you trade
- Firm vs indicative pricing. Make sure the quote is firm for your full size, not an indicative mid that moves before you execute.
- Settlement terms. Confirm the timeline and that destinations are whitelisted.
- Regulatory standing. Trade through a desk operating under licensed entities with proper KYC/AML.
- Coverage. Check the desk can source the instruments and corridors you need — a good desk isn't limited to what one exchange offers.
Common pitfalls
- Treating OTC like an exchange and shopping a large order around — that leaks information and worsens your price.
- Ignoring settlement risk; whitelisting and a clear settlement process matter as much as the rate.
- Using an unregulated counterparty to save a few basis points, then creating a compliance headache for your bank.

- Corporate treasuries managing large balances
- Payment processors and platforms settling size
- Funds and trading firms executing block trades

Frequently asked questions
What is OTC crypto trading?
Over-the-counter (OTC) crypto trading is executing a trade directly with a dealing desk at an agreed price, rather than on a public exchange order book. It's used for large or sensitive trades where pushing size through an exchange would move the price.
When should a business use an OTC desk instead of an exchange?
When the trade is large enough that an exchange order book would slip the price, when price certainty matters, or when discretion is needed. For small, routine trades an exchange is usually fine.
Does OTC trading avoid slippage?
Largely, yes. The desk quotes a firm price for the full size before you trade, so you know the rate up front rather than watching it move as your order fills.
How does settlement work?
After the price is agreed, funds and assets are exchanged on a defined timeline — settling to your wallet or bank account in crypto or fiat, depending on the trade.
Is OTC trading regulated?
It can be. Trading through a desk that operates under licensed entities with KYC/AML keeps execution compliant. Availability depends on jurisdiction and eligibility.
How is the price quoted?
The desk sources liquidity across multiple venues and quotes a single firm price for the whole order, often tighter than the effective price you'd get sweeping an exchange book.
