Cactus Custody Pushes MPC Self-Custody – Full Control, But Compliance Is the Catch

Digital asset custodian Cactus Custody announced it is rolling out a new institutional-grade self-custody platform built on Multi-Party Computation (MPC) as demand grows for secure digital asset control without reliance on centralized custodians.

The new platform is designed to give clients direct ownership of their assets while maintaining compliance-ready integrations with key anti-money laundering and Travel Rule technology providers, including Chainalysis and Notabene.

Institutional Self-Custody Powered by MPC

MPC tech has emerged as one of the most widely adopted security frameworks for digital asset management, allowing private keys to be split into multiple encrypted shares rather than being stored in a single location.

By using MPC, Cactus said it seeks to reduce the risk of single-point key compromise while allowing institutional clients to retain full control over their funds. The solution is positioned for organizations seeking autonomy and resilience in their custody infrastructure.

Cactus Custody Integrates Circle’s USDC Infrastructure

In December, Cactus Custody announced a collaboration with an affiliate of Circle Internet Group to improve access to USDC for institutional clients.

The firm has integrated Circle’s USDC infrastructure to improve workflow interoperability, allowing institutional clients to manage their digital asset operations.

Addressing Compliance Through Integrated Tooling

Alongside security, Cactus Custody explains compliance remains a central concern for institutions operating in the digital asset space. Cactus’ self-custody platform integrates with AML and Know-Your-Transaction (KYT) tools, such as Chainalysis, allowing clients to monitor on-chain activity and meet regulatory obligations.

Travel Rule compliance is also supported through integrations with solutions like Notabene, allowing institutions to exchange required transaction information as global regulatory frameworks tighten.

Targeting Clients Who Want Full Control

Daniel Lee, the CEO of Cactus Custody, told CryptoNews that the product is aimed at a broad range of institutions that prefer self-custody over third-party custodial models.

“The target client based would anyone that requires self custody solution. There are those that prefer self custody over using a centralised custodian,” Lee said.

He added that compliance tooling is flexible depending on client preference. “Chainalysis is an option for the client to use for their KYT [Know-Your-Transaction] obligations. However, if the client chooses another onchain analysis vendor we can also consider integrating it to our system,” Lee said.
