Frequently Asked Questions

What blockchain solutions do you build for banks?

Tokenized deposits, programmable payment rails, digital asset custody, and settlement infrastructure that integrates with existing core banking systems rather than replacing them.

Can this integrate with our existing core banking system?

Yes. We design a plug-and-play integration layer so blockchain capabilities (tokenization, settlement, custody) sit alongside your current core banking stack instead of requiring a rebuild.

How do you handle compliance and regulatory requirements?

Compliance requirements (KYC/AML, custody rules, reporting) are scoped during a discovery phase specific to your jurisdiction before any architecture decisions are made.

Do you support permissioned as well as public blockchains?

Yes. Depending on regulatory and privacy requirements, we build on permissioned/consortium chains or public networks like Ethereum, selecting the right fit during the discovery phase.
