Summary

Zero Hash has launched our Remittances product. This product allows remittance Platforms to offer capital efficient and low-cost remittance transfers to their End Customers. See detailed integration guide here.

Capital Efficient

Previously, offering instant remittance services (e.g., an American sending US Dollars to a recipient in Mexico who receives Mexican Pesos) required platforms to hold a local currency float in the destination country (e.g., holding Mexican Pesos in Mexico). This practice was necessary to offset the settlement delays associated with cross-border transfers, which can take up to 3 business days.

By leveraging the speed and efficiency of ~instant transfers on Layer 1 and Layer 2 blockchains, our solution allows Platforms to use USDC to completely eliminate the need to hold a local currency float. This innovation removes the traditional barriers associated with cross-border remittances, reducing both capital lock-up and operational complexity. Platforms can now offer seamless, near-instant transfers without the overhead of managing local currency reserves, enhancing liquidity and operational flexibility.

Low-cost

The aforementioned costs of legacy remittance flows are ultimately passed onto the End Customers. This new USDC-powered remittance flow allows Platforms to lower the fees passed onto End Customer while still maintaining sufficient margins

Use Cases

• Cross Border Remittances: Platforms can offer more capitally-efficient and cheaper remittance products to their End Customers

Developer Documentation

• Remittance Integration Guide here

Key Features

• Remittance API Suite: Streamline your remittance flow with just 5 simple, executable endpoints—while maintaining full control over your personalized front-end user experience (UX).
• USDC Support Across 10+ Blockchain Networks: Initiate remittance transactions on the blockchain network of your choice, with full support for USDC across multiple chains.
• Participant Tiering: Custom onboarding workflows that require minimal KYC data, ensuring compliance with regulatory standards while minimizing friction for users.
• Built-in Compliance: Zero Hash's transaction monitoring suite ensures that all transfers do not involve sanctioned or otherwise unpermitted actors
• Developer-Friendly: Access our comprehensive developer documentation to seamlessly integrate our solution into your platform.

This release will impact platforms who currently support DAY order types in the Central Limit Order Book

Summary

The Zero Hash Central Limit Order Book will now automatically expire DAY orders at the end of our established trading day, ending at 4:00PM Eastern (New York). This improvement will remove the need for platforms to handle the expiration of DAY orders independently, as our matching engine will expire these orders at 4:00 PM Eastern (New York) automatically, and send the Done for Day execution report via the corresponding FIX gateway.
