A practice of Client Focus
Build, ship, and operate blockchain for banks, fintechs, and crypto-native businesses.
About CF Blockchain
CF Blockchain is the blockchain practice of Client Focus — the technology services firm with production experience in complex blockchain delivery for banks, fintechs, and crypto-native businesses worldwide.
We don't write white papers. We ship live networks.
The real problem
Pilots stall. Smart contracts get audited but never go live. PoCs get a press release and quietly disappear from the roadmap.
The gap isn't engineering talent. It's the discipline that gets a system from working-on-testnet to running-with-real-money. Banking-grade controls. Operational instrumentation. Incident response that doesn't depend on the original developers being awake.
That's the gap CF Blockchain fills.
We've shipped both. Custom chains in production. Smart contracts running real money. NOCs monitoring real wallets. The full lifecycle, not just the build phase.

What we build
Production blockchain built to your specification. Public, private, or permissioned. Any consensus model. Any token economics.
Solidity, Vyper, Move, Rust. We write production smart contracts and we audit them.
Where blockchain meets regulated finance. Built with KYC/AML compliance from day one.
DeFi protocols, exchange backends, oracle networks, bridge architectures.
Real-world asset tokenization. Compliance-aware by default.
Blockchain as a Service
Build on the cloud you're already on. We deliver BaaS across every major platform.
Enterprise-grade Hyperledger Fabric deployments. Comprehensive development tools. Deep enterprise integration.
Scalable blockchain networks with Azure governance, AAD integration, and simplified development workflows.
High-performance Hyperledger Fabric on Oracle infrastructure with enterprise security baked in.
Managed Blockchain (Hyperledger and Ethereum) and Quantum Ledger deployments at AWS scale.
Direct deployments to Ethereum mainnet, Solana, Avalanche, Cosmos, Bitcoin, and the major L2s. No cloud abstraction layer when you don't need one.
How we operate
A purpose-built 24/7 NOC that combines deep blockchain expertise with enterprise operational discipline.
Beyond initial deployment, we keep your network running and current.
AI inside your blockchain stack
We integrate AI and automation to amplify the value of blockchain systems.
AI models that optimize contract execution paths, predict outcomes before commitment, and ensure compliance with policy at runtime. Reduces manual oversight, increases transaction integrity.
ML models analyze blockchain data continuously for anomalies, inconsistencies, and fraud signatures. Catches what manual review can't, at the speed your network actually moves.
Real-time risk assessment for transactions and wallet behavior. Predictive maintenance for network components. Operational telemetry that warns before things break.
Industries we ship for
Payment systems, securities settlement, trade finance, syndicated loans, tokenized deposits.
Provenance tracking, B2B transaction visibility, smart contract logistics.
Patient data integrity, clinical trial provenance, pharma supply chain.
Fleet provenance, smart mobility settlements, asset tokenization.
We bring specialist depth where the practice has shipped real systems. We say no when we can't.
How we engage
PoCs ship in 4 to 8 weeks. MVPs in 12 to 16 weeks. Production timelines scoped per engagement.
How we price
All pricing finalized in scoping call. Volume pricing available for portfolio commitments.
Why we win
Custom chains running in production. Smart contracts handling real value. NOCs monitoring real wallets at bank scale. We've shipped both PoC and what comes after.
KYC/AML, regulatory compliance, audit trails, and recovery protocols built in from day one. Not bolted on after the regulators ask.
Same firm engineers and operates your blockchain. No handoff to a separate ops vendor. No 3am calls to a developer who's no longer on contract.
We don't write white papers. We ship live networks.
What clients actually ask us
Public: Ethereum, Solana, Avalanche, Cosmos, Bitcoin, plus L2s (Base, Arbitrum, Optimism, Polygon zkEVM, zkSync). Private: Hyperledger Fabric, Quorum, Corda. BaaS: IBM, Azure, Oracle, AWS. If your stack isn't listed, ask. We probably know it.
Both. The choice is a function of your trust model and regulatory posture, not vendor preference. Banks often need permissioned. Crypto-native businesses need public. Most enterprises need both.
Hardware Security Module (HSM) integration for institutional-grade custody. Multi-sig for treasuries. MPC-based wallets where appropriate. We map the right pattern to your risk profile and regulatory requirements.
KYC/AML, Travel Rule, OFAC screening, MiCA, RBI, DPDP, FATF guidance. We design for compliance from day one. Specific framework expertise documented under NDA.
Yes. State migration, asset bridge architectures, and cutover orchestration. Gas-efficient migration paths where possible. Snapshot-based reissuance where not.
Smart contract audit (typically 2 to 4 weeks) is the smallest standalone engagement. Custom builds start at PoC scale (4 to 8 weeks).
Get in touch
30-minute scoping call. Tailored proposal within a week.
We scope fast and propose with specifics. Here's how the first week typically looks.
