Frequently asked questions
Engagement models, onboarding, data residency and evidence, answered in one place.
Build
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.
- Engagement
- Advisory and proof of concept through production handover
- Networks
- Public blockchains such as Ethereum, Solana and Base, and permissioned networks including Hyperledger Fabric
- Handover
- Every system transfers into the Digital Asset NOC with runbooks in place
Delivery lifecycle
From design review to handover
Every engagement is planned around the team that will operate the system once it is live.
No system enters the build schedule without a named operations owner.
Services
What the practice delivers
Six service lines cover the work from advisory through to production handover.
Chain engineering
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.
Production blockchain networks
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.
Banking and payments integration
Core banking, card, ACH and real-time payment rails connected to on-chain settlement, with reconciliation at every hop.
Smart contracts and tokenization
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.
Blockchain as a Service
Provisioning and lifecycle management on IBM Blockchain Platform, Microsoft Azure, Oracle and Amazon Web Services.
Advisory and proof of concept
Architecture and platform selection advice, and scoped pilots validated against production constraints rather than a demonstration environment.
Delivery approach
How work is planned and released
An operations owner from the first design review
No system enters the build schedule without a named operations owner, so monitoring, escalation and change requirements are set before code is written.
Release governance and test coverage
Front end, services, data and chain layers are delivered by one team with documented test coverage and a rehearsed rollback position.
Handover into the operations center
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
Where automation assists engineering
Artificial intelligence shortens engineering work. Accountable engineers review and approve everything it produces.
- Contract and code review assistance that flags risky patterns for an engineer to confirm.
- Test generation for integration paths, reviewed before it enters the pipeline.
- Migration and data mapping drafts for banking integrations, validated line by line.
