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.

POST/v1/otc/quotes
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.

01

Request a quote

Tell the desk the size and side of the trade you want to place.

02

Agree

The desk returns a firm price. Once you accept, that price is locked.

03

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.

Large treasury rebalancing that would move a public order book
Time-sensitive trades ahead of a settlement or reporting deadline
Trades where the counterparty relationship needs to stay off a public venue

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.

FAQ

Answers about OTC.

How is an OTC trade priced?
Tell the desk the size and side of the trade. The desk returns a firm price, and once you accept it the price is locked. That is the rate that settles.
Who handles settlement?
The same desk arranges and tracks settlement on both legs, so you are not coordinating across multiple counterparties.
