We are your blockchain development company in Paraguay
We build blockchain products for companies in Paraguay with our in-house team, and we design each token knowing whether it is a virtual asset or one of the distributed-ledger securities recognised by Law 7572/2025.
Tell us about your project
Blockchain development in Paraguay, 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 Paraguayan framework, from the architecture
Paraguay keeps three regimes apart: registration with SEPRELAD, reporting to the DNIT and securities law. Before choosing a network we decide where each function falls, because that changes the supervisor and the data the platform must keep.
Smart contracts ready for review
We write your business logic with tests and peer review. The code is prepared for an external audit and a phased deployment before it runs in production.
In your language and on your schedule
You speak Spanish directly with the people who design and code. Meetings fit into your office hours, and between them the project carries on through shared documentation and a stable technical channel.
A foundation ready to evolve
We document the code and plan deployments and monitoring. Your team receives a technical foundation for maintaining the product and adding features.

Use cases
Blockchain use cases in Paraguay
From cattle ear tags to maquila programmes, these cases start from controls Paraguay already applies and from a securities law that accepts distributed ledgers.
Agribusiness bonds on DLT
Bonds of an agribusiness issued and recorded on DLT, a way of representing securities that Article 73 of Law 7572/2025 expressly includes.
Blockchain for Banking & Finance
Beef traced through SITRAP
In SITRAP, regulated by SENACSA, each animal carries its ear tag and its origin and movements are recorded up to slaughter; the on-chain layer mirrors them without replacing that system.
Blockchain for Agribusiness
Lawfully sourced charcoal
Law 6676/2020 bans for ten years the trade in the Eastern Region of charcoal from unpermitted forest clearing; every batch linked to its plot and its permit.
Blockchain for Energy & Sustainability
Traceable maquila inputs
Maquila accounted for 68% of Paraguay's exports of industrial manufactures in 2023; every temporarily imported input traced to its re-export under Law 1064/1997.
Blockchain for Supply Chain & Logistics

Paraguay: SEPRELAD · BCP · DNIT
Blockchain regulatory framework in Paraguay
Paraguay splits the framework into three regimes that do not replace one another. Virtual asset service providers register with SEPRELAD for anti-money laundering purposes; Law 7572/2025, applied by the Central Bank through its Securities Superintendency, covers securities issued and recorded on DLT; and DNIT Resolution 47/2026 adds an information return on crypto-assets. No registration or return amounts to a financial licence.

Security
Security in blockchain development in Paraguay
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 Paraguay
What we are asked before a project starts.
Talk to our teamWhich regulations apply to a blockchain project in Paraguay?
It depends on each function. Anyone providing exchange, transfer, custody or management services for virtual assets registers with SEPRELAD and applies its AML controls; if the token grants negotiable credit, ownership or participation rights, it falls under Securities Market Law 7572/2025; and the DNIT sets an information return for the persons covered. None of those steps is a financial licence. We analyse the fit of your case before writing any code.
Do you work with both startups and established companies?
Yes. We support startups from MVP validation to their first round, and established companies on tokenization, traceability and digital identity projects with strict compliance requirements. In every case, smart contracts go through tests and review before they reach mainnet.
How do you work with Paraguayan companies?
In Spanish, talking directly to the people who design and build the product. Meetings are fitted to your working day, and the rest moves forward through shared documentation, written decisions and a stable technical channel.
How long does blockchain development take?
It depends on product complexity, integrations and the level of review it needs. Before development we set scope, dependencies and phase deliverables. That lets you decide what reaches production first and what waits for a second iteration, without mistaking an MVP for the complete architecture.
Which blockchain network is right for my project?
The one the product requirements call for, not the trend of the moment. 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, with the product's users in mind.
