Liminal Custody
Liminal
Liminal is an enterprise custody infrastructure certified SOC 2 and ISO 27001, with security built on MPC, HSM and multi-sig. Its strengths include an institutional-grade security standard and direct access to leadership. The main limitation is its purely B2B nature: it is not accessible to retail consumers.

Verdict
The top-tier score reflects an institutional security standard: SOC 2 and ISO 27001 certifications, custody on MPC, HSM and multi-sig, under FSRA (ADGM) and VARA (Dubai) oversight. A serious precedent weighs on it, though: Liminal was the custodian of the WazirX multisig breached for $230M in July 2024, with attackers exploiting a UI/data mismatch to upgrade the Safe contract — an incident that dents the security promise without erasing the technical credentials.
For those seeking self-determination the value falls sharply: even with a multi-sig and smart-contract architecture, Liminal is an enterprise infrastructure with full KYC, where keys and processes stay mediated by a supervised provider. The WazirX hack illustrates exactly the risk of the assisted-custody model: a mismatch in the custodian's interface was enough to compromise funds the end user did not directly control.
