Frequently asked questions
Engagement models, onboarding, data residency and evidence, answered in one place.
Client Focus engineers digital asset infrastructure, integrations and contracts for organizations that operate under supervision. Every engagement is planned around the operating model that will support the system once it is live.
Services
Six service lines cover the work from advisory through to production handover.
Network design, node and validator architecture, RPC topology and upgrade planning across public blockchains such as Ethereum, Solana and Base, and permissioned networks including Hyperledger Fabric, Corda and Canton.
Custom chains, nodes and validators built to the control expectations of banking supervisors, including FFIEC guidance and the OCC third-party risk management framework, with the controls, logging and reconciliation that regulated firms require.
Core banking, card, ACH and real-time payment rails connected to on-chain settlement, with reconciliation at every hop.
Contract design, review and deployment for named use cases including tokenized deposits, tokenized funds and stablecoin issuance, with automation applied to routine on-chain workflows and data verification.
Provisioning and lifecycle management on IBM Blockchain Platform, Microsoft Azure, Oracle and Amazon Web Services.
Architecture and platform selection advice, and scoped pilots validated against production constraints rather than a demonstration environment.
Delivery approach
No system enters the build schedule without a named operations owner, so monitoring, escalation and change requirements are set before code is written.
Front end, services, data and chain layers are delivered by one team with documented test coverage and a rehearsed rollback position.
Production cutover is supported around the clock, and the service is transferred into the Digital Asset NOC with runbooks and contact chains in place.

Artificial intelligence
Artificial intelligence shortens engineering work. Accountable engineers review and approve everything it produces.
