Fystack x HSC 2026: What Financial Institutions Need to Operate Digital Assets at Scale

On August 15, Fystack joined HSC 2026 as a sponsor, bringing together banks, fintechs, payment companies, digital asset businesses, and investors to discuss the next phase of digital asset adoption in Vietnam.

The Conversation Is Moving From Adoption to Production

Institutions are moving beyond experimentation and starting to think about what it takes to operate digital assets within existing financial infrastructure.

Regulation and compliance came up repeatedly, particularly around licensing, data residency, key management, and auditability.

Integration was another consistent theme. Institutions want digital asset infrastructure to connect with the systems they already run, from risk and compliance to reporting and approval workflows.

And as more use cases move toward production, security requirements are becoming more institutional. The focus is expanding beyond private key protection to access controls, policy enforcement, governance, and operational resilience.

The question is no longer whether institutions can access blockchain. It is whether blockchain infrastructure can meet the standards of the financial systems already in place.

What Institutions Need From Digital Asset Infrastructure

Vietnamese financial institutions already have established systems for managing risk, compliance, access, reporting, and governance.

They do not need to rebuild those systems around blockchain.

What they need is an infrastructure layer that can connect digital assets to the way they already operate.

This becomes increasingly important as institutional use cases expand beyond trading into stablecoin payments, cross-border transactions, digital asset services, and tokenization.

The infrastructure underneath these use cases has to work with existing financial operations rather than sit alongside them as a separate Web3 stack.

Going on-chain should extend existing financial infrastructure, not replace it.

That is the infrastructure gap Fystack is building for.

Making On-Chain Infrastructure Production-Ready

Fystack provides infrastructure for wallets, custody, policy controls, compliance, and stablecoin operations, designed to integrate into existing fintech and financial workflows.

The objective is straightforward: go on-chain in days, not months.

Instead of building wallet infrastructure, security systems, blockchain integrations, and operational controls from scratch, businesses can start with production-ready infrastructure and build their digital asset use cases on top of it.

For financial institutions, this means access to blockchain without having to become blockchain infrastructure companies themselves.

Fystack × Securosys: Flexibility in Custody Architecture

Another theme that came up at HSC was that not every institution has the same security and custody requirements.

MPC is Fystack’s default custody architecture, helping distribute private key protection and eliminate a single point of failure in transaction signing.

However, some institutions, particularly those with strict hardware security requirements, may need HSMs (Hardware Security Modules) as part of their custody architecture.

That is where Fystack’s partnership with Securosys comes in.

In this model, Securosys provides the hardware security layer through its HSMs, while Fystack provides the software infrastructure around it, from policy controls and approval workflows to multi-chain operations and compliance.

This gives institutions the flexibility to choose a custody architecture that fits their requirements, rather than having to adopt a single security model.

In other words, Fystack does not prescribe one security model for everyone. Institutions can use MPC or combine it with HSM-backed security, depending on their security, compliance, and governance requirements.

This was also one of the clearest takeaways from HSC: as digital assets move toward institutional adoption, infrastructure cannot simply work on blockchain. It also needs to fit the way financial institutions already manage assets, security, and operations.
