We are your blockchain development company in Argentina
We build blockchain products for companies in Argentina with our in-house team, designing each issuance around the CNV's VASP register and its regime for the digital representation of securities.
Tell us about your project
Blockchain development in Argentina, from idea to production
We turn your use case into a product you can launch, operate and grow. The same team designs the architecture, writes the contracts and integrates them with your systems.
Tell us what you want to buildThe Argentine framework, from the architecture
A VASP registration does not turn a token into a security with authorised digital representation. We separate the instrument being issued from the providers that distribute or hold it, and build the CNV's transfer restrictions into the contracts.
Smart contracts ready for audit
We code your business logic with tests and peer review. The code is ready for an external audit and a gradual deployment before it runs in production.
In Spanish and on your schedule
You work in Spanish with the people who design and write the code. Meetings are agreed within your working day, and day-to-day work continues through shared documentation and a technical channel.
A foundation to keep building on
We document the code and plan deployments and monitoring. Your team has a technical foundation for maintaining the product and adding new features.

Use cases
Blockchain use cases in Argentina
Cases built on controls Argentina already applies, from the INV analysis needed to export wine to the waybill carried by every grain truck.
Export wine
All wine Argentina exports needs its INV export analysis; each consignment is linked to its winery, its analysis certificate and its shipment.
Blockchain for Agribusiness
Grain waybills
Since 2021 the electronic waybill has been the only valid document for moving grain by truck or rail, and each trip carries its grain traceability code.
Blockchain for Supply Chain & Logistics
Puna lithium
Argentina holds the world's largest identified lithium resources, 28 million tons according to the USGS; each batch is linked to its salt flat, its plant and its buyer.
Blockchain for Energy & Sustainability
Digital real estate trusts
The CNV allows trust securities to be represented digitally in its sandbox, with the traditional security on deposit and transfers restricted to designated VASPs.

Argentina: CNV · UIF
Blockchain regulatory framework in Argentina
Argentina regulates virtual asset services through Law 27,739 and the CNV's VASP register, which requires capital, systems and ongoing controls on top of anti-money laundering duties owed to the UIF. Tokenized securities follow their own regime: RG 1150/2026 widened the eligible instruments and extended the sandbox to 31 December 2027, with transfers restricted to the VASPs designated for each issuance.

Security
Security in blockchain development in Argentina
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 Argentina
What we are asked before a project starts.
Talk to our teamWhich regulations apply to a blockchain project in Argentina?
Anyone exchanging, transferring or holding virtual assets for third parties registers as a VASP with the CNV, in categories with different minimum capital, and complies with UIF Resolution 49/2024 on anti-money laundering. If the token represents a negotiable security, the issuer also needs digital representation authorisation, including under automatic offering, and transfers are restricted to the designated VASPs. We analyse the fit of your case before writing code.
Do you work with both startups and established companies?
Yes. We support startups from MVP validation to their first funding round, and established companies on tokenization, traceability and digital identity projects with strict compliance requirements. In every one of them, smart contracts go through tests and review before reaching mainnet.
How do you work with Argentine companies?
In Spanish and in direct contact with the people who design and build the product. Decision meetings are set within your working hours, and the rest moves forward through shared documentation and a stable technical channel.
How long does blockchain development take?
It depends on product complexity, how many integrations it needs and the level of review required. Before development we settle scope, dependencies and phase deliverables. That lets you decide what reaches production first and what waits for a second iteration, without treating an MVP as the final architecture.
Which blockchain network is right for my project?
The one that fits the product requirements, not the most talked about. 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. In an issuance under the CNV regime, interoperability and synchronisation between the participating VASPs also weigh in.
