Blockchain
Infrastructure.
Built for Production.
We design and build custom blockchain architecture, DeFi systems, L1 protocols, smart contracts, and Web3 infrastructure for startups and enterprises that need it to actually work.
One of the few blockchain development companies globally to have led custom L1 blockchain protocol development from scratch — including consensus mechanism design, smart contract runtime engineering, and cross-chain interoperability architecture.
/ Technologies We Work With
We solve the hard problems in blockchain infrastructure.
Blockchain expertise across every major sector.
We have delivered production systems across financial services, supply chain, healthcare, gaming, and beyond. Each industry has distinct requirements — we know them.
Protocol-level depth. Not just smart contract surface.
We Have Built at the Protocol Layer
Our team led core protocol development on a custom L1 blockchain — consensus mechanism design, smart contract runtime, cross-chain architecture. That depth is rare and it changes how we approach every project.
We Build for Production
Not prototypes. Not MVPs that break at scale. Every system we deliver is designed for real transaction volumes, real users, and real operational demands. We think in terms of infrastructure longevity.
We Tell You What You Actually Need
We do not recommend blockchain because it sounds impressive. We analyze requirements and recommend the architecture that genuinely fits — even if that means a simpler solution than expected.
What blockchain infrastructure actually delivers.
Not theoretical benefits. Measurable outcomes from production deployments on the stack we specialise in.
Trade Finance Processing
Contour reduced letter of credit processing time using R3 Corda with HSBC and Standard Chartered.
Supply Chain Trace Time
IBM Food Trust with Walmart cut food provenance tracing from days to 2.2 seconds using Hyperledger Fabric.
Transaction Volume
Broadridge DLR processes over $35 billion in daily repo transactions on infrastructure like what we build.
The Fine Art Ledger
NFT marketplace and provenance infrastructure we built for artists and collectors worldwide.

From first call to production. Exactly what to expect.
Full process detailsFree Strategy Call
30 minWe start with a 30-minute call to understand your project, your goals, and whether blockchain is genuinely the right fit. No sales pitch. We will tell you honestly what we think.
Architecture Proposal
3–5 daysWe prepare a detailed architecture proposal covering technology recommendations, system design, key trade-offs, and our reasoning. You receive this before any contract is signed.
Scope and Contract
2–3 daysWe agree on a clear scope, timeline, milestones, and fixed or retainer pricing. Full NDA if required. We do not start work until you are fully comfortable with the engagement terms.
Build Phase
Varies by scopeWeekly update calls, shared project board, and access to our engineers throughout the build. You are never left wondering what is happening. Milestones are defined upfront and tracked.
Testing and Security Review
1–3 weeksComprehensive test coverage, smart contract auditing, security review, and performance testing under load conditions. We do not deploy until the system passes our production readiness checks.
Production Deployment and Handover
1 weekDeployment to production infrastructure with full documentation, runbooks, and knowledge transfer sessions. Your team will understand the system, not just have a codebase they cannot maintain.
Ongoing Support and Partnership
OngoingPost-launch support, monitoring, and the option to engage on a retainer basis for continuous development. Most of our clients stay with us long-term because the relationship works.
