Cobo and BlockSec Partner to Bring Built-in KYT to Cobo MPC Wallet Customers

Cobo, a global digital asset custody and wallet infrastructure provider, and BlockSec have deepened their long-standing partnership: customers using Cobo MPC wallets can now access BlockSec's real-time Know Your Transaction (KYT) screening directly, with no separate integration. The integration builds on years of collaboration between the two companies in smart contract audits and security monitoring.

About Cobo

Founded in 2017 and headquartered in Singapore, Cobo provides custodial, MPC and exchange wallets, Wallet-as-a-Service and on-chain payment infrastructure to more than 680 clients across around 50 countries and regions. Cobo holds licensed entities in Hong Kong, Canada and the United States, has achieved SOC 2 Type II and ISO 27001 certifications, and reports zero security incidents since 2017.

The challenge: compliance has to travel with the wallet

Exchanges, payment companies, fund managers and other institutions choose Cobo MPC wallets to control their own assets securely. But every one of them also has to meet AML/CFT obligations: knowing where incoming funds came from, blocking exposure to sanctioned or illicit addresses, and keeping an audit trail for regulators.

Sourcing, integrating and maintaining a separate KYT vendor adds cost and engineering work, and leaves a gap between where funds move and where risk is checked. For institutions that need both security and compliance, screening works best when it is built into the wallet infrastructure itself.

How Cobo and BlockSec work together: built-in KYT, backed by years of security partnership

Built-in KYT for Cobo MPC wallet customers. BlockSec's Phalcon Compliance is integrated with Cobo's wallet infrastructure, so Cobo MPC wallet customers can screen deposits and withdrawals for AML and sanctions risk in real time, drawing on BlockSec's address intelligence covering more than 600 million labeled addresses. Customers get:

• Real-time KYT and KYA screening of counterparties and transactions
• Fund tracing to understand the source and destination of funds
• Compliance reporting to support internal review and regulatory requirements

The same KYT capability also powers the Cobo Payment API, which Cobo and BlockSec launched together in March 2026 to secure cross-border stablecoin payments.

A multi-year security partnership. Long before the KYT integration, BlockSec worked with Cobo on smart contract audits and real-time security monitoring with Phalcon Security. That track record of working together on security laid the foundation for extending the partnership into compliance.

The result: security and compliance in one wallet stack

• 600+ Cobo MPC wallet customers able to use BlockSec KYT directly
• One integration instead of separate wallet and compliance vendors
• Years of joint work across security audits, security monitoring and compliance
