Production Blockchain Engineering on Hyperledger Fabric + EVM Chains
Our team designs and builds private+public hybrid blockchain systems — Hyperledger Fabric for sensitive operational data, Polygon and Ethereum for tradeable tokens, with verifier-gated bridges between them. We engineer the chaincode, the integrations, the wallets, the exchanges, and the IoT-to-chain pipelines that make real-world assets work on-chain.
What Our Team Builds on Blockchain
Blockchain is not one thing — it is a stack of decisions about trust, privacy, throughput, and who gets to write. Our engineering team makes those decisions deliberately, and builds the layers below in production-grade code.
Hyperledger Fabric
Chaincode in Go or TypeScript, multi-org channels, MSP identity setup, and Fabric SDK integration for permissioned operational ledgers.
EVM Smart Contracts
Solidity contracts deployed on Polygon and Ethereum L2s, audited patterns, gas-aware design, and full Hardhat or Foundry test coverage.
Private-to-Public Bridges
Verifier sign-off workflows that move issuance events from Fabric to public chains, with replay protection and on-chain attestation.
Token Standards for RWA
ERC-20 fungible, ERC-721 non-fungible, and ERC-1155 multi-token contracts mapped to real-world asset rules and lifecycle states.
IoT-to-Chain Pipelines
Smart meter, sensor, and edge device telemetry signed, batched, and written to the ledger with verifiable provenance end to end.
Exchange & Wallet Infrastructure
KYC and AML/CFT onboarding, custody patterns, order matching, and wallet flows engineered for regulated digital asset operators.
Flagship Case Study: Carbon Credit Tokenisation Platform
From smart meter to tradeable token — a two-system blockchain vertical engineered and operated by our team.
MRV Platform
Measurement, reporting, and verification on Hyperledger Fabric. Smart meter telemetry is ingested, validated, and written to a permissioned chain where verifiers approve issuance of carbon credits with a full audit trail.

A regulated digital asset exchange where verified credits become tradeable tokens on a public EVM chain. KYC, custody, order matching, and on-chain settlement are all engineered in-house by our team.
Read the Exchange Architecturearrow_forwardThe two platforms connect through a verifier-gated bridge: the MRV chain issues carbon credits once measurement data is approved, and only those approved issuances are minted as tradeable tokens on the Exchange. The private ledger holds the operational truth; the public chain holds the market.
Beyond Carbon Credits: Where Blockchain Earns Its Place
The the Client pattern — private ledger for the operational truth, public chain for the market — generalises. These are the verticals our team is built to deliver into.
Real-World Asset (RWA) Tokenisation
Tokenised representations of physical goods, commodities, real estate fractions, or fund units with on-chain ownership and lifecycle rules.
Supply Chain Provenance
Track-and-trace ledgers that record custody handoffs, certifications, and condition events from origin to end customer.
Regulated Securities Cap Tables
On-chain share registers with whitelisted transfer rules, lockups, and reporting hooks for regulators and auditors.
Energy & Sustainability MRV
Verifiable measurement of generation, consumption, and offset data — the the Client pattern applied to broader energy markets.
Trade Finance & Invoice Tokenisation
Tokenise receivables and trade documents so financiers can fund and settle against a single source of truth.
Identity, Certification & Credentials
Verifiable credentials and certification registries that organisations and regulators can check without a central gatekeeper.
Our Default Blockchain Stack
These are the tools our engineering team reaches for first. We are not religious about any of them — but we are opinionated, because we have shipped with them.
Hyperledger Fabric
Permissioned operational ledgers where only known parties can read, write, and validate. Used wherever data is sensitive, regulated, or organisation-specific.
- checkChannels for data partitioning between orgs
- checkMSP identity and certificate authority setup
- checkFabric SDK integration into application stacks
- checkChaincode in Go or TypeScript
Polygon & Ethereum L2s
Public EVM chains where tokens are tradeable, ownership is globally verifiable, and any wallet can participate. Used wherever the market needs open access.
- checkSolidity contracts on Polygon and Ethereum L2s
- checkHardhat or Foundry for test, build, and deploy
- checkOpenZeppelin contracts for audited token standards
- checkethers.js and web3.js for dApp integration
Integrations
IPFS for off-chain document storage, The Graph for indexing on-chain state, custom Hyperledger APIs for enterprise applications, IoT edge SDKs for device-side signing, and KYC/AML providers for regulated onboarding.

Blockchain MRV Platform
How our team built the 5-layer blockchain MRV pipeline from smart meters to Polygon-minted carbon tokens.
Digital Asset Exchange Platform
Hyperledger Fabric as the trading core: KYC/AML, multi-asset wallets, and carbon-plus-crypto matching.
Hybrid Design Pattern
Why “private chain vs public chain” is the wrong question for real-world asset tokenisation projects.
