This subscription notifies makers when new Block RFQs are created in the specified currency (or all currencies if `any` is used) that they can potentially quote on. Each notification includes: - **RFQ identification:** Unique Block RFQ ID, creation timestamp, and expiration timestamp - **RFQ structure:** Multi-leg trade structure with instrument names, directions (buy/sell), and ratios for each leg - **Trade parameters:** Total amount (multiplied by leg ratios determines trade size), minimum trade amount, and optional combo identifier - **Hedge information:** Optional hedge leg details including instrument, direction, amount, and price - **RFQ state:** Current state (open, filled, cancelled, or expired) - **Counterparty information:** Taker rating, taker alias (if disclosed), and disclosure status - **Execution details:** For filled RFQs, includes trade information with prices, amounts, directions, and maker aliases - **Index prices:** List of index prices for underlying instruments at trade execution time (for filled RFQs) - **Rating information:** Whether the RFQ is included in taker rating calculation (for closed RFQs) Makers can subscribe to specific currencies (BTC, ETH, USDC, USDT) or use `any` to receive notifications for all supported currencies. This enables makers to monitor incoming RFQ opportunities and respond with competitive quotes in a timely manner. **Scope required:** `block_rfq:read` **📖 Related Article:** [Deribit Block RFQ API walkthrough](https://docs.deribit.com/articles/block-rfq-api-walkthrough) ## AsyncAPI ````yaml api-reference/coinbase-deribit-app-api/adv-starbase-asyncapi.json block_rfq.maker.(currency) id: block_rfq.maker.(currency) title: 'block_rfq.maker.(currency) ' description: > Real-time notifications for Block RFQs (Request for Quotes) that are available for the subscribed maker to respond to.
