Cactus Custody

Company and ownership

Cactus Custody is the institutional digital asset custody business of BIT, the Singapore-headquartered group that traded as Matrixport until March 20, 2026. BIT calls the change a brand update, with legal entities and client contracts left as they were. The group was founded in 2019 and has offices in seven countries and regions. Jihan Wu is co-founder and chairman, and John Ge is co-founder and CEO. BIT reports more than $6 billion in assets under custody and management, and a July 2025 release said Cactus serves more than 3,000 institutions. Hedgeweek named Cactus its Custodian of the Year: APAC for a third straight year in June 2026.

Custody model and security

Cactus sells two separate products. In Full Custody, Cactus holds and manages the whole private key. In MPC Self-Custody, the client keeps its own master key share while Cactus holds its share inside an SGX trusted execution environment, and the two products run on independent infrastructure with separate accounts. BIT says 98% of assets sit in air-gapped cold vaults, with sites in Switzerland and Asia. Keys are protected with MPC/TSS and multisig, on HSMs that BIT describes as FIPS 140-3 Level 3 or higher. Client wallets are segregated, with approval workflows and address whitelisting on top.

BIT says Cactus holds SOC 1 Type II and SOC 2 Type II reports. The September 2026 Swiss launch notice adds that the SOC reports and Cactus's ISO 27001 and 27701 certifications apply to the Hong Kong and Bhutan entities. The new Swiss service, run by ChainTech AG, generates and holds keys on FIPS 140-2 and 140-3 HSMs in Swiss data centers and keeps no key copies or backups outside Switzerland.

Regulation and insurance

BIT states that Cactus is licensed in Hong Kong and Bhutan. On BIT's license list, Matrix Trust Company Limited holds a Trust or Company Service Provider license from Hong Kong's Companies Registry, a license BIT dates to September 2019. Two Bhutan entities, Matrix Bhutan Pte Ltd and Matrix Gelephu Pte Ltd, hold financial services licenses from the Gelephu Financial Services Office. Matrix Bhutan's in-principle approval in January 2026 listed providing custody among its activities, and the full license followed in February 2026. In Switzerland, ChainTech AG is a member of VQF, a self-regulatory organization recognized by FINMA. Elsewhere in the group, Fly Wing Technologies holds a MAS major payment institution license for digital payment token services.

OneDegree insures the Hong Kong and Bhutan custody entities. BIT said in September 2026 that it plans to extend that cover to the Swiss entity and will confirm the extension separately.

Products and integrations
