Trade size, without moving the market.
Place large or sensitive trades directly with a dedicated desk, priced and settled away from public venues.

Interactive demo
See OTC in action.
Tap through OTC on screen, or use Next. The panel shows each API request and the webhook events your systems receive.
OTC
The desk screen. A firm price comes from POST /v1/otc/quotes, and POST /v1/otc/orders accepts it.
Tell the desk the size and side of the trade you want to place.
curl --request POST \ --url "$DEOSX_API_URL/v1/otc/quotes" \ --header "Accept: application/json" \ --header "Authorization: Bearer $DEOSX_API_KEY" \ --header "Content-Type: application/json" \ --data '{ "side": "BUY", "pay": { "amount": 2500000, "currency": "USD" }, "asset": "USDT", "network": "TRON"}'

What it unlocks
Why institutions use OTC.
Trade size discreetly
Large tickets are priced and executed away from public order books, so size alone doesn't move the market against you.
One desk, start to finish
Pricing and settlement on both legs are handled by the same desk, not coordinated across multiple counterparties.
The price that settles
The rate agreed with the desk is the rate that settles, no slippage between quote and execution.
How it works
From instruction to record, in three steps.
Request a quote
Tell the desk the size and side of the trade you want to place.
Agree
The desk returns a firm price. Once you accept, that price is locked.
Settle
The desk arranges and tracks settlement on both legs, recorded on the same platform as every other DEOSX Banking Solutions product.
Where this fits
Use cases.
Security
Bank-grade by default.
Compliance is not a department we consult. It is the rail the platform runs on.
KYB before the first quote
Every counterparty is verified before it can request a price.
Dual approval on every trade
No single person moves institutional money. Booking and approval are separated by role.
Screening inside the settlement path
Sanctions and Travel Rule checks run inside the lifecycle, not after the fact.
An audit trail that holds up
Every quote, approval and settlement leg is timestamped with its actor and kept.
