Stack of 3D glass slates layered together

Enterprise Architecture & Integration

Blockchain inside the IT stack you already run.

Most blockchain consultancies treat distributed ledger as a separate world. The pilot ships, then collides with SAP, the core banking system, the identity layer, the KYC/AML stack, and the cloud security posture — and stalls. We design the integration paths first. The on-chain components are the easier half of the problem.

Signals you're a fit

When to engage us in this mode?

You're a fit for Enterprise Architecture & Integration if:

You've validated a use case and now need a real architecture — not a slide.

If the path isn't designed yet, you probably want Strategic Advisory or Product & Protocol Development instead, depending on whether you need the use case validated or the on-chain build executed.

Our approach

What we do

01

Public, private, and hybrid architecture design

We start from the requirements — performance, finality, privacy, governance, regulatory — and design the smallest architecture that meets them. Sometimes that's a public chain with privacy primitives. Sometimes it's a permissioned chain with selective public anchoring. Sometimes it's two ledgers connected by a clearing layer. We don't have a default answer.

02

ERP and core banking integration

SAP S/4HANA, Oracle Financials, Temenos, Mambu, Finacle, FIS, and the rest. We design the data flows, the settlement boundary, the reconciliation model, and the failure modes. We've seen what breaks in production at scale and we design around it.

03

API and middleware layer design

We design the API contracts, the event model, the idempotency guarantees, the retry semantics, and the observability layer that lets your operations team actually run the system at 3am.

04

On-chain/off-chain data synchronization

Which data goes on-chain. Which stays off. How they reconcile. How you handle reorgs, reorg-equivalent events on permissioned chains, and operational outages. How you prove consistency to an auditor. We've made every mistake here that's worth making, and we know the patterns that hold.

05

Cloud and blockchain infrastructure design

AWS, GCP, Azure, and the relevant regulated cloud variants. Node operations, key management, HSM integration, network segmentation, disaster recovery, and the run-cost model your CFO will actually approve.

Deliverables

What you get

A typical engagement runs three to six months for the architecture phase and produces:

  1. A reference architecture document that holds up under technical and regulatory review.

  2. Detailed integration designs for each system in scope (ERP, core banking, identity, KYC/AML, custody).

  3. API specifications, event schemas, and middleware design at sufficient depth that engineering can build from them.

  4. An on-chain/off-chain data model with the reconciliation, audit, and recovery patterns specified.

  5. A cloud and infrastructure design with run-cost projections and operational runbooks scoped.

  6. A phased implementation plan with the highest-risk integrations sequenced first.

  7. A risk register, with the failure modes we've actually seen at other clients flagged explicitly.

If you continue into build, the same team executes against the architecture they designed. No handoff. After launch, the same team is available for ongoing support, optimization, and integration adjustments as your systems and requirements evolve.

Where most pilots fail (and how we design around it)

A short list of patterns we see repeatedly:

01 / 05

Reconciliation deferred to "phase two"

Off-chain and on-chain ledgers diverge, no one notices for a week, and the recovery is manual and painful. We design reconciliation in from day one, with explicit divergence alarms.

02 / 05

Identity bolted on after the fact

The DLT system has its own user model, the bank has another, and the mapping is fragile. We design the identity boundary first.

03 / 05

Key management treated as an afterthought

MPC, HSM, and signing infrastructure get specified late, then drive a six-month delay when security review pushes back. We design key management with security and compliance in the room from week one.

04 / 05

Cloud cost surprise

Node infrastructure, indexer infrastructure, and observability infrastructure cost three to five times what the pilot suggested. We model run-cost honestly, in front of the CFO if needed.

05 / 05

No one to call when the integration breaks

The consulting firm that designed the architecture is gone. The internal team wasn't in the room for the design decisions. A change that should take days takes months because no one understands the integration boundary. We stay as a technical partner specifically to prevent this.

Related engagement modes

Architecture work often pairs with:

Tokenization & Financial Infrastructure

When the architecture is for issuance, settlement, or custody.

Product & Protocol Development

When the build is in scope after design.

Bring us a real problem

We'd rather spend 30 minutes telling you which of our five engagement modes fits — or that none of them do — than send you a generic capabilities deck. Book the call.
