What We Build
Blockchain Capabilities
Production-grade blockchain systems engineered for institutional security and enterprise compliance.
Smart Contract Development
Solidity and Rust contract engineering with gas optimisation, invariant fuzzing, and pre-audit hardening — targeting zero critical findings before external audit submission.
Audit-ready contracts that pass Certik, Trail of Bits, and OpenZeppelin reviews.
DeFi Protocol Engineering
AMM, lending, staking, and yield vault protocol development with economic security modelling, oracle manipulation resistance, and flash-loan protection.
Institutional-grade TVL security without compromising capital efficiency.
Real-World Asset Tokenisation
ERC-1400 security token platforms for real estate, securities, and commodities with KYC gating, transfer restriction enforcement, and dividend automation.
Fractional ownership with built-in regulatory compliance.
Web3 Application Development
Full-stack decentralised applications with wallet integration, real-time on-chain event handling, subgraph deployment, and consumer-grade UX.
Protocol adoption beyond crypto-native audiences.
DAO Governance Infrastructure
On-chain governance contracts, delegation mechanics, timelock controllers, and multi-sig treasury management providing the security decentralised organisations require.
Community trust through transparent, attack-resistant governance.
Cross-Chain and Layer 2 Development
Chainlink CCIP, LayerZero, and Wormhole integration for cross-chain token transfers with message validation, replay protection, and bridge security.
Multi-chain reach without multi-chain risk surface.
Enterprise Permissioned Blockchain
Hyperledger Fabric and Quorum consortium networks for supply chain, trade finance, and regulated data sharing — delivering immutability without public-chain exposure.
Blockchain benefits inside your security perimeter.
Blockchain Data Indexing and Analytics
The Graph subgraph development, custom on-chain indexers, and protocol dashboards converting raw blockchain events into structured operational intelligence.
Real-time protocol visibility without running your own archive node.
How We Deliver
From Protocol Design to Mainnet
Protocol Design
We map protocol mechanics, tokenomics, access control architecture, upgrade strategy, and governance model — with security threat modelling identifying attack vectors before a line of contract code is written.
Contract Engineering
Solidity or Rust development with NatSpec documentation, unit tests, integration tests, fuzz campaigns, and gas optimisation. Quality targets: 100% branch coverage, audit-ready standard.
Internal Security Review
Systematic review against the full SWC Registry and DeFi attack taxonomy — reentrancy, oracle manipulation, access control, flash loan surface — resolving findings before external audit.
External Audit
We coordinate external audit with Certik, Trail of Bits, or OpenZeppelin matched to your TVL and risk profile — managing triage, remediation, and audit sign-off before mainnet deployment.
Web3 App and Integration
Frontend application, subgraph deployment, wallet integration, transaction UX, and enterprise system API bridges — delivering the full-stack experience protocol adoption requires beyond the contract layer.
Launch and Monitoring
Phased mainnet deployment with TVL caps, real-time anomaly detection, on-chain monitoring dashboards, incident response runbooks, and governance tooling for ongoing parameter management.
Enterprise Use Cases
Blockchain in Production
Institutional DeFi Yield Infrastructure
Challenge
Asset manager needed to deploy institutional capital into DeFi with MPC custody, AML-compliant monitoring, and governance controls retail protocols lacked.
Solution
Institutional DeFi layer with audited contracts, multi-sig governance, on-chain AML monitoring, and regulatory reporting designed for licensed financial entities.
Outcome
$4.1B simulated TVL in stress tests. 100,000+ transactions with zero settlement failures. 8.4% optimised APY vs 5.1% baseline.
Real Estate Asset Tokenisation Platform
Challenge
Real estate fund sought to tokenise $200M in commercial property for fractional ownership while maintaining SEC Regulation D compliance.
Solution
ERC-1400 security token platform with KYC-gated onboarding, transfer restriction enforcement, and automated dividend distribution.
Outcome
$42M in tokens sold in the first offering. Investor onboarding reduced from 14 days to 4 hours. Secondary market volume reached $8.4M/month.
Pharmaceutical Provenance Network
Challenge
Pharmaceutical distributor needed immutable provenance tracking for controlled substances across 12 facilities to meet FDA DSCSA compliance.
Solution
Permissioned Hyperledger Fabric network with product tracking smart contracts, ERP integration, and DSCSA-compliant automated reporting.
Outcome
Full DSCSA compliance across all serialised units. Counterfeit detection capability established network-wide. FDA audit documentation generated automatically.
Cross-Chain Yield Aggregator Launch
Challenge
Protocol team launching yield aggregation across Ethereum, Arbitrum, and Polygon needed audited contracts, secure cross-chain messaging, and an accessible frontend.
Solution
Audited vault contracts on three chains with Chainlink CCIP, automated rebalancing logic, and a consumer-grade web application with embedded transaction guidance.
Outcome
Certik audit passed with zero critical findings. $34M TVL in 90 days. $12M in cross-chain bridge transfers without incident.
DAO Treasury and Governance System
Challenge
Protocol DAO with $84M treasury managed informally through multi-sig, with no on-chain governance creating operational risk and community distrust.
Solution
Governor Bravo governance with delegation, proposal lifecycle management, 48-hour timelock, Gnosis Safe integration, and on-chain treasury infrastructure.
Outcome
Governance participation increased from 8% to 34% of token supply. All decisions fully on-chain. Three adversarial proposals blocked by quorum design.
Bank Consortium Trade Finance Network
Challenge
Regional bank consortium needed shared trade finance infrastructure for letter of credit automation with permissioned access and full regulatory audit trail.
Solution
Hyperledger Fabric network across 8 banks with smart contract LC issuance, document hash verification, and automated settlement triggering.
Outcome
LC processing reduced from 7 days to 4 hours. Documentary fraud eliminated. Consortium participants reported 34% reduction in trade finance operational costs.
