Release Details

Release Date: January 20th, 2025 - Zero Hash will be feature flagging this feature on in a phased approach, per Platform, during the week of January 20th. Our goal is to enable this across every Platform by the end of the week (Friday, January 24th)

Release Type

Informational – Optional action from platforms

Summary

Zero Hash is debuting its CREATE2 smart contract deployment capabilities. CREATE2 is an Ethereum opcode for creating smart contracts that was introduced as part of Ethereum Improvement Proposal (EIP) 1014 and implemented during the Constantinople upgrade (February 2019).

Specifically, CREATE2 ensures that neither the End Customer, Zero Hash, nor the Platform (depending on your setup) will be charged a network fee until we're sure that a deposit is coming. This can significantly increase product margins, completely eliminating unnecessary costs.

This release impacts the following networks:

• Arbitrum
• Avalanche
• Base
• Ethereum
• Optimism
• Polygon

📘

Platforms do not need to take any action to implement CREATE2, as it is the default standard for all deposit addresses out-of-the-box

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

• 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
