Best Digital Asset Custodians With Bank-Grade Security

Faced with a flurry of sophisticated hacking attempts, ever-evolving regulatory frameworks, and operational bottlenecks, institutions entering the virtual digital assets market are forced to look beyond traditional custody measures.

A digital assets custodian safeguards large-scale digital assets on behalf of institutions, helping them focus on expansion, scaling, and other critical operations. Besides offering secure asset custody, a digital assets custodian also helps institutions navigate the intricate regulatory environment and enhance operations efficiency through automation. A reliable digital assets custodian should be easy to integrate and must offer timely support for the resolution of issues.

The Need For Bank-Grade Security For Digital Asset Institutions

Banks in TradFi are successful because they have the trust of individuals and businesses alike. The rigorous set of security measures implemented by banks ensures that the assets are secure even in an adverse scenario. Banks embrace sophisticated technology and features like 2FA to prevent fraud, unauthorized access, or theft. On top of that, banks also provide insurance coverage for additional assurance.

Institutions jumping on the digital assets bandwagon expect custody solution providers to emulate this bank-grade security and rightly so. The digital assets market has serious security risks, rug pulls, regulatory challenges, and operational bottlenecks. Bank-grade digital assets custody is paramount to tackling these risks. But what does bank-grade security in digital assets actually mean?

Since the emergence of the traditional financial system, bank-grade security has been the gold standard for financial institutions. Reason? It encompasses the highest levels of protection and reliability. To draw a parallel between bank-grade asset custody in TradFi and DeFi, one could cite examples of custodians implementing features like multi-sig authentication and 2FA, a comprehensive insurance policy, and certifications like CCSS. This blog sheds light on the top 3 digital assets custodians with bank-grade custody.
