The platform serves fintechs, exchanges, wallet providers, and financial institutions expanding into digital asset services, with custody, storage, and transfers powered through an institutional-grade custody partner.

Institutional and corporate clients use the suite to trade, safeguard, and generate yield on digital assets through a single relationship rather than separate consumer products.

Paribu Custody is an institutional digital asset custody service for crypto trading platforms, banks, and other organizations in Turkey. It protects keys with a proprietary security architecture combining multi-party computation, hardware security modules, and secure enclaves.

The service also offers staking access through partner operators, transaction monitoring, and Travel Rule compliance tooling.

Liminal Digital Asset Custody is a custodian service that holds and safeguards institutional digital assets through segregated accounts and hardware security modules. It combines multi-party computation and hardware-based key protection with insurance coverage and proof-of-reserve reporting to protect client holdings. Exchanges, funds, and other institutions use the service to store assets across multiple blockchain networks under a compliance-oriented custody framework.

Liminal HSM Vault is a custody product combining multi-party computation and hardware security modules to provide cold storage for digital assets held by regulated institutions such as banks.

Cactus Custody is a digital asset custody service for institutions. Assets sit in unique, segregated blockchain addresses that are verifiable on-chain, with keys held offline in hardware security modules across multiple regions.

Cactus Oasis is an off-exchange settlement service for institutional traders. Assets stay in segregated buffer accounts that are verifiable on-chain until a trade settles, which removes counterparty exposure to insolvency or fund misappropriation at trading venues. Oasis notifies users when assets miss settlement requirements or exceed risk thresholds, limiting losses to one settlement cycle.

Client assets are held in segregated, bankruptcy-remote on-chain wallets, with redundant wallet technologies, approval workflows, and customizable risk screening.

SINOHOPE Custody Platform provides institutional wallet and custody services in two modes. The MPC wallet splits private key control across several parties for self-custody, while the full custody wallet offers a managed custodial setup. Both include approval workflows, role-based permissions, and compliance monitoring, and APIs let developers integrate wallet functions into their own applications.
