Quotes

Partners must request an executable quote before creating a subscription or redemption request. Quotes define:
  • flow type
  • asset pair
  • executable pricing
  • quote expiration
  • expected settlement amounts

Supported Flows

Subscription

USDT → USTBL

Redemption

USTBL → USDT

Quote Request

Partners request quotes by providing:
  • flow type
  • asset pair
  • amount
  • settlement parameters

Quote Response

A successful quote response includes:
  • quote ID
  • amount in
  • amount out
  • expiration timestamp
  • supported settlement information

Quote Expiration

Quotes are time-limited. Expired quotes cannot be used to create requests. Partners are responsible for creating requests before expiration.

Executable Pricing

Quotes represent executable commercial terms at the moment of creation. Once created, quote validity is governed exclusively by the quote expiration timestamp. Underlying market changes do not modify an already issued quote.

Quote Lifecycle

Quotes support the following lifecycle states.

ACTIVE

The quote is valid and may be used to create requests.

EXPIRED

The quote expiration timestamp has been reached. Expired quotes cannot be used operationally.

CONSUMED

The quote has already been used to create a request. Consumed quotes cannot be reused.
