A single hedge locks an exchange rate for a future transaction between two currencies. - name: Dual Hedges description: >- A dual hedge mitigates FX risk by automatically generating two linked hedge legs - a customer leg and a supplier leg - both routed through the customer's functional currency. This structure reduces exposure to currency fluctuations for both cash flow and accounting purposes, while allowing independent tracking and reporting of each hedge leg. - name: Customers description: >- Customer objects represent your end customers on the Grain platform. A customer must be created before a hedge or spot transaction can be initiated. - name: Pricing description: >- Pricing endpoints provide access to FX rates for currency pairs that are not being hedged. These endpoints can be used for live rate display or bulk retrieval to support high-volume quoting workflows. - name: Spots description: >- Spot objects represent currency conversions executed for immediate or near-term settlement. - name: Conversions description: >- Conversion objects represent currency conversions executed for immediate or near-term settlement. - name: Wallets description: Endpoints to view balances, manage funding, and perform transfers. paths: /dual-hedge-offline-rates: get: tags: - Dual Hedges description: >- Returns a full table of dual hedge rate proposals for all configured currency pairs.
