In traditional MPC and HSM custody, the vendor acts as a co-signer or holds key material in its own infrastructure. If that vendor is compromised, coerced or simply unavailable, the institution's assets are at risk. Rox Vault eliminates this dependency by design: the vendor has no shards and no signing role.

A vendor's promise not to use its signing ability is irrelevant to supervisors; the ability itself is what gets classified. Systems where the vendor could theoretically sign are treated as higher-risk custody or outsourcing arrangements. Rox Vault is built so that no signing capability exists to classify.

When approval policies and signing run inside the same vendor-controlled system, there is no deterministic link between a human decision and the signature it produces. Rox Vault splits them across independent boundaries, one for intent, one for execution, so the approval and the signature become the same auditable event.

Each regulator imposes distinct technical and operational requirements, and a design built for one framework often fails another. Rox Vault's framework provides jurisdiction-specific compliance mapping across eight major regulatory bodies, so institutions can operate across markets without rebuilding their compliance infrastructure.
