Distributed ledger engineering, minus the hype.
Audited smart contracts and distributed ledger systems for real business cases.
The short version
Blockchain earns its place in a narrow set of problems: shared state between parties who do not fully trust each other, provable provenance, and settlement without an intermediary. Where it fits, it fits well.
We build and audit those systems — and we will tell you plainly when a database and a signed audit log would serve you better for a fraction of the cost.
What good looks like
- Contract test coverage target
- 100%Contract test coverage target
- Independent audits before mainnet
- 2×Independent audits before mainnet
- Provenance, once deployed
- ImmutableProvenance, once deployed

The work we take on inside this practice, and what each piece is actually for.
Smart contracts
Solidity and Rust contracts written against a documented threat model and covered by exhaustive test suites.
Security audits
Static analysis, fuzzing and manual review against the known exploit classes, with a remediation report.
Tokenisation
ERC-20, ERC-721 and ERC-1155 implementations with compliance and transfer-restriction requirements built in.
Permissioned networks
Hyperledger Fabric and private EVM chains for consortium and supply-chain use cases.
Web3 integration
Wallet connection, transaction UX and gas handling that non-crypto users can actually complete.
Chain infrastructure
Node operations, indexers and subgraphs so your application reads chain state reliably.
From first conversation to handover
Fit assessment
We pressure-test whether decentralisation genuinely solves your problem before writing a line of contract code.
Design
Contract architecture, upgrade strategy, key management and an explicit threat model.
Build & test
Full-coverage test suites, fuzzing and testnet deployment under adversarial conditions.
Audit & deploy
Independent audit, remediation, then mainnet deployment with monitoring and an incident runbook.

Asked often, answered plainly
If yours is not here, ask us directly — we answer these the same way on a call.
Do we actually need a blockchain?
Often not, and we will say so in the first workshop. It earns its keep when multiple parties need shared state without a trusted intermediary. Otherwise a well-designed database with signed audit logs is cheaper, faster and easier to operate.
How do you handle audits?
We run internal review and automated analysis throughout, then commission an independent third-party audit before mainnet. Contracts are immutable once deployed — the cost of finding a bug afterwards is unbounded.
Which chains do you work on?
Primarily EVM chains (Ethereum, Polygon, Arbitrum, Base) and Solana, plus Hyperledger Fabric for permissioned enterprise networks.
