Secure, Scalable, Seamless: How Safeheron Powers HashKey OTC Global’s Expansion

HashKey OTC Global is the institutional OTC arm of HashKey Group, serving as a regulated bridge between crypto and fiat across Asia and the Middle East. As one of the few OTC desks licensed in multiple jurisdictions—including Hong Kong, Singapore, Japan, and the Middle East—HashKey OTC Global supports high-volume trading and crypto-fiat conversion for enterprises and high-net-worth clients. With global expansion accelerating, HashKey OTC Global needed a custody solution that matched its operational scale, asset diversity, and regional compliance obligations.

Why Safeheron? Enabling Secure, Scalable Asset Management

The Challenge: High-Volume, Multi-Chain Operations Without Friction

As HashKey OTC Global’s client base and transaction volumes grew, so did the complexity of wallet management. Customers held assets across multiple blockchains. Using traditional manual processes to manage these multi-chain assets was cumbersome and resource-intensive. HashKey OTC Global needed a custody solution that could support multi-chain architecture, regional team workflows, and high operational reliability — without the long lead time of building a solution in-house.

The Solution: Fast, Flexible, and Secure Infrastructure Built for Growth

To support its fast-growing OTC operations, HashKey OTC Global integrated Safeheron’s plug-and-play SaaS platform, enabling rapid deployment without the long development cycles typical of in-house wallet systems. This provided a future-ready custody framework that balances speed, security, and operational flexibility.

Key benefits include:

• Frictionless deployment and scaling: Safeheron’s APIs and SaaS architecture allowed HashKey OTC Global to go live quickly, with minimal engineering resources. Wallet generation is fully automated, enabling the team to assign client wallets in seconds and streamline onboarding.

• All-in-one multi-chain asset management: With support for all major blockchains, Safeheron enables HashKey OTC Global to use one standardized multi-signature system across chains, eliminating the need to manage separate setups for EVM-compatible chains, Solana, TRON, and others. This reduces operational complexity and improves efficiency in multi-chain environments.

• Customizable governance with robust security: Safeheron’s TEE-powered Policy Engine allows HashKey OTC Global to build flexible, institutional-grade approval workflows tailored to its internal structures and global jurisdictions. Policies can be configured across multiple dimensions such as transaction type, asset type, risk level and etc. Every transaction must go through rigorous approval before execution, providing safeguards against internal errors, collusion, or external compromise.

• Automated compliance and fund consolidation: With the Auto Sweep feature, client assets are automatically consolidated into secure treasury accounts, eliminating manual effort. Built-in AML/KYT monitoring helps HashKey OTC Global maintain compliance across regulated markets.

• MPC and TEE-backed key security: Safeheron’s architecture uses MPC and TEE-based multi-layer security model to guarantee private key shard protection. The original private key is never exposed, not even during transactions, ensuring unmatched security in real-world operational conditions.

As HashKey OTC Global continues to scale across regions and assets, Safeheron provides a reliable, secure, and adaptable custody solution. Its combination of deployment speed, operational simplicity, and institutional-grade protection makes it a go-to partner for OTC institutions navigating the demands of global crypto-fiat infrastructure.
