Commissioning Blockchain Development
Tomohiro Iida · Published April 7, 2026 · Updated July 11, 2026
Commissioning blockchain development means asking an outside company, one with specialist skills in languages such as Solidity, Rust, or Go and an established audit-partner relationship, to build a smart contract (a self-executing program that runs on a blockchain) and the systems around it. Compared with ordinary web development, the typical cost is JPY 2,000,000-30,000,000 and up over a 2-to-8-month-and-up timeline. Choosing a vendor comes down to five points (chain experience, audit capability, communication and language, contract structure, and operational handover), and the process itself runs in four steps: requirements framing, quote comparison, a PoC contract, and production implementation. This article lays out the specific questions to ask when commissioning the work and how to run the process. Vendor-selection criteria in general, and the cost breakdown, are covered in separate articles.
Key takeaways
- Outsourcing gives fast access to specialist blockchain engineers and lets a company focus on the work without the up-front cost of hiring and training in-house; the trade-off is that in-house knowledge builds up more slowly.
- Vendor selection should check five things: Web3-specific delivery track record, ability to advise on chain selection, security-audit capability, clear communication structure, and post-launch maintenance capability.
- The standard process runs four steps: consultation and requirements gathering, requirements definition and technology selection, PoC and prototype validation, then production development, testing, and release.
- Cost tiers run from roughly JPY 2,000,000-8,000,000 for a small single-contract build to JPY 30,000,000 and up for an enterprise system with regulatory and audit requirements.
Outsourced development versus in-house development
Whether to outsource blockchain development or build it in-house comes down largely to how hard it is to hire the right engineers and how tight the project timeline is.
- Outsourced development
- Gives immediate access to specialist blockchain engineers; keeps in-house costs (hiring, training) down so the team can focus on the work itself; the trade-off is that in-house knowledge builds up more slowly.
- In-house development
- Builds know-how inside the company over the long run; requires time and cost to hire and develop engineers; finding blockchain-specialist talent is harder than for general roles.
- The development window is 6 months or less and speed matters most
- There is no in-house blockchain engineer
- A PoC is used to validate the technology first, with in-house development considered later
Five things to check before commissioning a vendor
Choosing a blockchain development vendor calls for checking specialist technical depth on top of the usual criteria for a systems-development vendor.
- 01. Blockchain-specific track record
- General web development experience and blockchain development experience are not the same thing. Ask for specific delivery examples by area: smart contracts, DID, token design.
- 02. Ability to advise on chain selection
- Ethereum, Polygon, Symbol — choosing the right chain for the requirements directly affects overall project cost and performance. Whether a vendor can explain the trade-offs across multiple chains is a good indicator.
- 03. Security-audit capability
- A smart-contract vulnerability translates directly into asset loss. Confirm in advance whether the vendor has an audit-partner relationship, can provide a security checklist, and has a testnet-verification process.
- 04. Clear communication structure
- Before signing, confirm the point of contact, how often you will get status updates, and the escalation path if an issue comes up. Misalignment during development tends to drive up rework cost.
- 05. Maintenance and operations capability
- Confirm the vendor can support blockchain-network updates and gas-fee fluctuation after launch, and agree on post-delivery support scope and cost up front.
We can support all five areas above, from chain selection through arranging an audit partner and ongoing maintenance.

The standard flow for commissioning blockchain development is consultation, requirements definition, PoC, and production development. Skipping a step tends to increase rework cost later.
- Step 1, consultation and requirements gathering — lay out what you want to achieve, the problem, your budget range, and your timeline. Putting "why blockchain" into words at this stage makes the discussion that follows go more smoothly.
- Step 2, requirements definition and technology selection — document functional and non-functional requirements, and settle on the chain, stack, and security policy. This is not a phase to rush, since its precision directly determines quote accuracy.
- Step 3, PoC and prototype validation — confirm the core functionality on a testnet. Surface risk before production development, and complete any requirements or technology-choice revisions at this stage.
- Step 4, production development, testing, and release — move to production development based on the PoC results, then release in stages after a contract audit, mainnet deployment, and security testing.
Blockchain development carries a high cost of fixing a design mistake once it reaches production. Resolving technical uncertainty through a PoC before moving to production lowers total cost.
Cost and timeline by tier
Cost for outsourced blockchain development varies with project scale, chain, and the complexity of system integration. The following is a rough guide at the point of commissioning; a phase-by-phase breakdown and what to check in a quote are covered in a separate article on development cost.
| Tier | Cost range | Typical duration | Scope |
|---|---|---|---|
| Small | JPY 2,000,000-8,000,000 | 2-4 months | A single standalone smart contract, no integration with existing systems, a simple admin UI. |
| Standard | JPY 8,000,000-30,000,000 | 4-8 months | Multiple interacting contracts, integration with an existing database, an admin panel and front end included. |
| Enterprise | JPY 30,000,000 and up | 8+ months | A full-scale system including regulatory compliance, audit, and large-scale user support; common in financial and government projects. |
- Chain selection — infrastructure cost differs between a public and a private chain
- Audit requirements — a third-party audit adds roughly JPY 2,000,000-5,000,000
- Number of integrated systems — more existing databases or APIs to integrate means more effort
- Regulatory work — financial and government-facing projects carry additional legal-review cost
Cost and development timeline vary significantly by chain choice. Selection criteria for EVM-compatible, public, and private chains are covered in detail in a separate article.

Commissioning blockchain development means going to a vendor with Solidity, Rust, or Go expertise and an audit relationship, rather than a general web-development shop.
Choosing between outsourcing and in-house development comes down to engineer-hiring difficulty and project timeline. Outsourcing suits a tight timeline or a lack of in-house blockchain expertise; in-house development builds lasting internal know-how but takes longer to staff.
When commissioning a vendor, check five things: Web3-specific track record, ability to advise on chain selection, security-audit capability, a clear communication structure, and maintenance capability. The process itself runs four steps: consultation, requirements definition, PoC, and production development, and skipping the PoC step tends to raise rework cost later.
