Komainu is a natural candidate for institutions comparing regulated, segregated custody and institutional governance; Zodia Custody for buyers interested in bank-backed custody positioning and off-venue settlement through Interchange; and Hex Trust for institutions evaluating custody and digital-asset services across Asian and international jurisdictions. The decisive issue is the contracting entity, legal custody model and supported workflow in the buyer's jurisdiction.
The short answer
Komainu, Zodia Custody and Hex Trust all target institutional digital-asset clients, but a logo-level comparison is not enough. Komainu emphasizes segregated institutional custody and multi-jurisdiction regulation. Zodia Custody combines custody with services such as Interchange and white-label infrastructure. Hex Trust presents custody and related institutional services through entities serving different jurisdictions, with a notable Asia footprint.
The buyer must compare the exact legal entity that will hold assets. A global brand can operate through multiple regulated and unregulated entities, and not every asset or service is available under every license.
Side-by-side comparison
| Decision factor | Komainu | Zodia Custody | Hex Trust |
|---|---|---|---|
| Primary orientation | Institutional, segregated digital-asset custody | Institution-focused custody, off-venue settlement and white-label solutions | Institutional custody and digital-asset services across multiple jurisdictions |
| Strong starting point | Asset managers and institutions prioritizing custody governance and segregation | Institutions examining custody plus trading-settlement workflows | Institutions needing regional coverage, especially in Asian markets |
| Product question | Which entity, account model and custody controls apply? | How do custody, Interchange and other solutions divide legal responsibility? | Which jurisdictional entity supports each asset and service? |
| Evidence to request | Custody agreement, segregation opinion, key governance, recovery and audit material | Entity map, custody and Interchange terms, settlement sequence and recovery evidence | License map, supported-asset matrix, custody architecture and operational controls |
| Main risk to manage | Assuming company-wide positioning applies identically to the contracted service | Combining custody and settlement claims without mapping each counterparty | Treating global coverage as uniform across local entities and products |
Komainu
Komainu publicly describes institutional custody with segregated on-chain custody, governance controls and regulated operations across multiple jurisdictions. Its materials also reference security architecture, a client portal and risk controls.
Good fit: Institutions that want a custody-led operating model and place high weight on account segregation, governance and regulated service delivery.
Verify: Contracting entity, regulatory permissions, legal title and segregation, sub-custody, key architecture, withdrawal governance, supported assets, staking treatment, insurance, incident response, audit evidence and exit mechanics.
Zodia Custody
Zodia Custody presents itself as an institution-first custodian and offers custody alongside Interchange, which is positioned around off-venue settlement, and white-label solutions.
Good fit: Institutions that want to compare safekeeping together with a controlled trading or settlement operating model.
Verify: Which assets remain in custody during an Interchange workflow, who bears settlement and counterparty risk, how collateral or settlement instructions are governed, the role of third parties, and which regulated entity delivers each service.
Hex Trust
Hex Trust offers institutional digital-asset custody and publishes jurisdiction-specific information, including for Singapore. Its custody materials emphasize security controls, role segregation and asset coverage that can vary by entity.
Good fit: Institutions evaluating a provider with regional digital-asset operations and service coverage across Asia and other markets.
Verify: Local license and entity, supported assets by jurisdiction, account segregation, key management, withdrawal policy, staking and DeFi boundaries, reporting, incident response and portability.
What institutional buyers should test
Begin with legal and operating architecture, not a feature demo. Ask each provider to show the entity map, custody agreement, asset-support matrix and responsibility model. Obtain legal advice on title, segregation, liens, insolvency treatment and any sub-custodian relationship.
The operational pilot should cover a deposit, a small withdrawal, a new address, an approval-policy change and a rejected transaction. Test recovery after the loss of an authorized device or staff departure. Confirm that statements, on-chain balances and internal records reconcile without manual screenshots.
Security diligence should examine key generation and storage, quorum administration, privileged access, software dependencies, business continuity, penetration testing and incident notification. Insurance should be read as a contract with exclusions and limits, not as a general promise that every loss is covered.
Avoiding overlap with other custody comparisons

FAQ
Which custodian is best for institutions?
There is no universal best custodian. The right provider depends on contracting entity, jurisdiction, assets, governance, settlement, staking, recovery and reporting requirements.
Are all three providers regulated in every market?
No. Regulatory status and service availability are entity- and jurisdiction-specific. Verify the exact entity and permissions for the intended service.
What is off-venue settlement?
It generally aims to reduce the need to pre-fund or leave assets on a trading venue. Buyers must still examine legal terms, settlement mechanics and counterparty exposure.
Does segregated custody eliminate insolvency risk?
No. Segregation is important, but buyers should obtain legal analysis of title, account structure, sub-custody, liens and treatment under applicable law.
What should a custody pilot test?
Test account setup, deposits, withdrawals, policy changes, a new destination, reporting, incident escalation, recovery and export of records.
