The gap between blockchain development companies is wider than in almost any other software category, and the pricing does not signal it.
Some are engineering teams that have shipped systems carrying real value for years. Some are template shops that fork a repo, change the colours and hand you something that has never seen adversarial traffic. Here is how to tell.
Ask to see something live
Not a demo. A system running now, with real users and real value moving through it.
This single request filters aggressively. Demos are cheap and every shop has one. A demo is a happy path with the failures removed — and in this category the failures are the entire job. Anyone can make a matching engine work at ten orders per second on a laptop.
Follow it with: what broke, and what did you do about it? Teams who have operated real systems have specific, slightly weary answers. Teams who have not talk in generalities.
Ask where the code is written
Who specifically writes it, where do they sit, and are they employees or subcontractors?
There is nothing wrong with distributed teams — ours spans Dubai, the United States and Noida. What matters is whether the people are consistent and accountable. A project handed to whichever contractor was available that month produces code nobody can maintain afterwards, and you find that out when you need a change six months in.
Ask what happens after launch
This is the question that most reveals whether you are talking to an engineering team or a project shop.
Blockchain systems are not finish-and-forget. New chains, dependency updates, new attack patterns, changing partner APIs. Something needs attention continuously.
Find out: do they maintain what they build, what the arrangement looks like, and what happens if you want to take the code in-house. Ask what you get on exit and in what format, and ask it before you sign, not after.
Understand where cost actually comes from
The contract is rarely the expensive part. Cost concentrates in places that are invisible from a feature list:
- Integration count. Every banking partner, custody provider, identity vendor, chain and exchange is its own build, its own edge cases and its own test surface. This is the single biggest driver.
- Custody model. Third-party providers are fast to launch with ongoing fees; a custom MPC stack is more up front and less over time.
- Chain coverage. Each additional chain multiplies monitoring, reconciliation and failure modes.
- Operations depth. The admin console and support surfaces are where your team lives every day, and they get scoped last by almost everyone.
- Audit coordination and remediation. Budget for fixing what audits find, not just for the audits.
Anyone quoting a number before understanding those is guessing at it.
The audit question
Ask directly: who audits, who pays, and who fixes what they find.
We coordinate independent third-party firms — we book and manage the calendar, and the audit report comes from them, not from us. We do not perform audits. Any development company telling you it audits its own code is describing a conflict of interest, not a service.
Two independent firms is the sensible baseline for anything holding meaningful value, plus formal verification on the parts where a bug is unrecoverable.
Where the legal line sits
A development company builds to constraints; it does not define them.
Your counsel decides what permissions you need, which markets you can operate in, and what transfer or holder rules apply to your token. Those answers shape the architecture profoundly — key management, onboarding flow, fund segregation, transfer hooks written into the contract itself — and they are extremely expensive to change after deployment.
So get them early. A development partner offering you regulatory guidance is offering something it is not qualified to give.
What we build
Exchanges and matching engines, wallets and custody, smart contracts, token infrastructure, RWA platforms, payment rails, neobanking systems, and the AI layers on top.
1,100+ projects since 2016, 95+ specialists, with the marketing team in the same building — which is why our launches do not announce features that are still in staging.
Common questions
What does a Web3 development company do?
Builds the on-chain and off-chain systems a crypto product runs on: smart contracts, exchanges, wallets and custody, token infrastructure, RWA platforms, payment rails and the admin surfaces operators live in. The stronger firms also handle the unglamorous parts - reconciliation, monitoring, key management and the operations console - which are where most of the engineering effort actually goes and where template shops tend to stop.
How much does blockchain development cost?
Cost is driven by the number of integrations, the custody model, how many chains you support, how much of the operations surface you need at launch, and audit coordination. The contract itself is usually a small share of the total. Integration count is the variable that moves an estimate most, because every banking partner, custody provider, identity vendor and chain is its own build and its own test surface.
What questions should I ask a blockchain development company?
Who writes the code and where do they sit? What happens after launch - do you maintain it? How do you handle audits and who pays for remediation? What does your operations console look like? Can I see a system you built that is live now? Ask for a live system specifically - anyone can show a demo, and the gap between a demo and something carrying real value is the entire job.
Should we hire freelancers or a development company?
Freelancers work well for bounded, well-specified pieces of work. A company earns its place when the system has several moving parts that have to agree - contracts, backend, custody, apps and operations - because the coordination between those is where projects fail. The practical difference is what happens when something breaks six months in: a team still exists, and an individual contractor may not.
What does Corum8 build?
Exchanges, wallets and custody, smart contracts, token infrastructure, RWA platforms, payment rails, neobanking systems and the AI layers on top of them - plus the marketing that goes around a launch. We have delivered 1,100+ projects since 2016 with 95+ specialists, and we coordinate independent third-party audits rather than performing them ourselves.
