We are your blockchain development company in the Netherlands
We build blockchain products for companies in the Netherlands with our in-house team, designing each project around MiCA and the way supervision is split between the AFM and DNB.
Tell us about your project
Blockchain development in the Netherlands, from idea to production
We take your use case to a product you can launch, operate and extend. One team designs the architecture, writes the contracts and connects them to your systems.
Tell us what you want to buildThe Dutch framework, from the architecture
The AFM handles CASP authorisation and DNB oversees prudential requirements, so we design custody, permissions and records for both. We also separate client assets legally and operationally, because setting up a stichting is not enough.
Contracts ready for an audit
We write your business logic with tests and peer review. Every contract is documented and prepared for an external audit, then deployed in stages before it runs in production.
In your language and on your schedule
You work in English, or in Spanish if your team prefers, directly with the people who design and write the code. Meetings follow your working hours, and the rest is handled through shared documentation and a stable technical channel.
A foundation that can keep growing
We hand over documented code with deployments and monitoring planned, so your team can maintain the product and add features on a foundation it understands.

Use cases
Blockchain use cases in the Netherlands
Cases that build on specific Dutch rules, from each dairy farm's phosphate rights to the end of solar netting in 2027.
Rotterdam containers
The Port of Rotterdam handled 212 million tonnes in the first half of 2026; the record shares each container's status between shipping line, terminal and haulier.
Blockchain for Supply Chain & Logistics
Dairy phosphate rights
A dairy farm needs phosphate rights for its herd size; farmers sell or lease them to one another, report each transfer to RVO and 30% is usually withheld on transfers.
Blockchain for Agribusiness
Real estate participations
Transferring property requires a deed from a Dutch notary and registration with the Kadaster; the token represents a participation or a claim against the issuer, not the property.
Blockchain for Real Estate
Household solar surplus
From 1 January 2027 annual netting (saldering) ends: electricity fed into the grid is paid for separately by the supplier; the record keeps every kWh fed in.
Blockchain for Energy & Sustainability

European Union: MiCA / AFM · DNB
Blockchain regulatory framework in the Netherlands
In the Netherlands, MiCA applies with shared supervision: the AFM handles CASP authorisation and leads their supervision, while DNB oversees prudential requirements and leads supervision of ART and EMT issuers. The transition for the former DNB registration ended on 30 June 2025, earlier than the European maximum. A token that is a financial instrument follows securities rules, and a real estate token does not replace the notarial deed or registration with the Kadaster.

Security
Security in blockchain development in Netherlands
Every delivery goes through the same checklist before it reaches mainnet. What changes between projects is the depth of each control, because an MVP does not carry the same risk as a contract that holds third-party funds.
Before mainnet
- Roles and permissions defined for every critical function
- Unit and invariant tests, and fuzzing on the logic that moves value
- Static analysis and peer review of every change
- Multisig and timelock on administration when the risk justifies it
- Custody and rotation of the deployment keys agreed
- External audit when the value at risk requires it
We work with leading audit firms
FAQ
Frequently asked questions about blockchain development in Netherlands
What we are asked before a project starts.
Talk to our teamWhich regulations apply to a blockchain project in the Netherlands?
MiCA governs crypto-asset issuance and services. CASP authorisation and, for eligible financial entities, the Article 60 notification go through the AFM; DNB supervises prudential requirements and ART and EMT issuers. Notifying a white paper does not mean the supervisor has approved it. AML and sanctions obligations also apply and, if the token is a financial instrument, so do securities rules. We analyse the fit of your case before writing any code.
Do you work with both startups and established companies?
Yes. With startups we work from MVP validation to a product they can present in a funding round; with established companies, on tokenization, traceability and digital identity projects with demanding compliance requirements. Either way, smart contracts go through tests and review before they reach mainnet.
How do you work with Dutch companies?
In English or Spanish, in direct contact with the people who design and build the product. Meetings fit into your working day, decisions are put in writing, and shared documentation and a stable technical channel keep the work organised.
How long does blockchain development take?
It depends on product complexity, the integrations with your systems and the level of review required. Before development we set the scope, dependencies and deliverables of each phase, so you can decide what reaches production first and what waits for a second iteration. From the start, the plan separates an MVP from a complete architecture.
Which blockchain network is right for my project?
The one your product requirements call for. For EVM projects we compare Ethereum, Polygon, Arbitrum or Base on finality, costs, tooling, interoperability, custody and compliance, and we consider non-EVM networks when they fit better. The recommendation covers contracts, indexing, wallets and operations, and takes into account who will use the product.
