Use a shared ledger when several parties must rely on the same record, reconciliation, settlement, provenance, or workflow that a private database cannot settle. Dev House Australia is a blockchain development company: we design the thinnest path that still owns that problem, then build the contracts, applications, and integrations around it. If a conventional system is enough, we say so. Delivery is backed by Dev Centre House's 15+ years of global engineering, with collaboration that fits Australian business hours.
Bring the parties involved, the record that must be shared, and the systems the product must talk to. We will say whether a ledger is justified and outline a first milestone, in Australian time zones.
CLIENTS
Scope
This page is the commercial home for ledger-backed software. We do not treat an ICO, an NFT marketplace, or a DAO product as the default engagement.
Solidity and EVM contracts for payments, escrow, access control, and workflow automation, written for testability, upgrade paths, and clear on-chain behaviour. Review and automated tests are part of the build. An independent audit is scoped when the risk requires it; we are not an audit firm.
Permissioned or consortium designs when participants, data, and governance must stay controlled, plus the application layer operators actually use. Public networks when the brief needs them.
Ledger events connected to ERP, CRM, and customer channels without a rip-and-replace. If the job is only a conventional system, that work belongs on custom software development.
Threat modelling, key management, access policies, and monitoring for wallets, nodes, and APIs. We use testnet, staging, and production so behaviour is proven before it is irreversible.
The web or service surface people use to read the record, submit a transaction, or operate the workflow, including wallet connection when the product needs it.

Technology Expertise
We pick the network and languages the use case needs, not a catalogue of coins. Typical production work sits on the platforms and languages below.
Use cases
These are operating contexts we scope, not a claim that every sector needs a chain. Industry pages that already exist are linked.
Reconciliation, settlement, and shared workflow between parties who cannot take one organisation’s database as the source of truth.
A record several organisations must trust for origin, handover, or compliance evidence along a supply chain.
Document or process records where agencies or partners need the same history, not a copy each can edit alone.
Consent, credential, or exchange workflows where integrity and access rules matter more than a public token.
Approach
A useful ledger product is a path, not a chain name. We design the thinnest path that still owns the workflow, and we stop at a database when that is the honest answer.
Shared truth, more than one party, and a cost to later dispute. If those are missing, we recommend conventional software instead of a chain.
Who may write, who may read, and which rules must stay inside your organisation. That choice drives network, identity, and hosting.
What must be enforced on-chain versus in the services and interfaces your team already operates.
How events land in ERP, CRM, finance, or operations systems so the ledger is not an island.
Automated tests, contract review, and a testnet or staging path before production. External audit when the brief includes it.
Keys, monitoring, network upgrades, and the people who operate the product once it is live.
Why talk to us
The call is a scoping conversation, not a pitch deck. You leave knowing whether a ledger is the right tool and what the first milestone would be.
If one party already owns the data and the others will accept that system, we recommend conventional software. That honesty is the point of discovery.
We start with the parties, the shared record, and the systems you already run. Ethereum, Hyperledger, or a database comes after that, not before.
We outline the smallest build that still owns the workflow (contracts, integration, or a spike) with who does what after launch.
The office is in Sydney. Delivery is backed by Dev Centre House globally, with overlap that fits Australian business hours.
We do not have a published blockchain case study. The software work below is what we can show. We will not invent project counts or audit badges to win the meeting.
Process
Discovery comes before a chain name. We agree the business rules, then architecture, then the build you can operate.
Workshops capture the business problem, the parties, compliance constraints, and whether a ledger is justified before any contract or UI work begins.
Network model, identity, wallet or key flows, and integration diagrams align engineering and stakeholders on scope, releases, and acceptance criteria.
Iterative delivery of contracts, services, and interfaces with automated tests and demos in your project tools, so risks surface before production.
Contract review, testnet or staging, and (when the brief requires it) a plan for an independent audit. Effort and timeline stay visible.
Production release with monitoring, key hygiene, and patch releases as networks and business rules change.
If that path matches the problem you have, book the call or use the form at the bottom of this page. Bring the parties, the shared record, and the systems involved.
Cost
We do not publish a fixed project price. The estimate follows the work: whether a ledger is justified, how many parties write, what must be enforced on-chain, and what you integrate after launch.
After a short discovery conversation we can outline a first milestone. Use the form below or book a call. We will not invent a number before the scope is clear.
Reviews & Testimonials
When more than one organisation must rely on the same record, and a later dispute is expensive. Reconciliation, settlement, provenance, and shared workflow are typical. If one party already owns the data and the others will accept that system, a conventional database is usually enough.
Use this page when the product needs a shared ledger, contracts, or a permissioned network. Use custom software development when the system can live in a database and APIs you control. If you are unsure, start here. We will say which path fits.
Both, when the brief needs them. Smart contracts own on-chain rules. Enterprise or consortium designs own controlled participants and data. Web3 or DApp work is the application surface on top, not a separate commercial page.
We review and test the contracts we write. When the risk requires an independent audit, we plan for a specialist firm. We do not sell a standalone audit product or a certification badge.
Those are not the default offering. If a brief includes a token, a collectable, or community voting, we will say whether we can take that slice as software work and what legal advice you still need. We do not run token sales.
No. The Australian office is in Sydney. There is no separate blockchain page per city. Australia-wide commercial intent stays here.
Send the parties involved, the record that must be shared, and the systems the product must talk to. We will recommend whether a ledger is justified and outline a first milestone. Use the contact page or book the call from this page.
