Crate otc_rfq 

OTC RFQ Engine

High-performance OTC Request-for-Quote engine supporting DeFi protocols (0x, 1inch, Uniswap, Hashflow) and TradFi venues via FIX 4.4.

Architecture

This crate follows Domain-Driven Design with a layered architecture:

• Domain Layer (domain): Core business logic, entities, value objects, and domain events
• Application Layer (application): Use cases, services, and orchestration
• Infrastructure Layer (infrastructure): External adapters, repositories, and integrations
• API Layer (api): gRPC, REST, and WebSocket interfaces

Example

use otc_rfq::application::use_cases::CreateRFQUseCase;
use otc_rfq::domain::value_objects::{Quantity, Symbol};

// Create an RFQ request
let rfq = CreateRFQUseCase::new(/* dependencies */)
    .execute(request)
    .await?;
