Smart Contract Development & Audit in Kecskemét
Smart contracts are the trust layer of every blockchain product — one vulnerability can drain a treasury overnight. Hurain Technologies writes, tests, and hardens Solidity and Rust-based smart contracts for tokens, NFTs, DeFi protocols, and enterprise use cases, with security review built into every stage rather than bolted on at the end. In Kecskemét, that means building to the technical expectations of the local market.

Localised for your market
Smart Contract Development in Kecskemét: local requirements we build for
Currency, tax, payments, data protection and 24/7 support — planned into the project from the first sprint.
Currency & pricing
Prices, invoices and reports in forint (HUF), with the transaction currency and FX rate stored on every record for cross-border sales.
Tax (VAT / GST)
Hungary applies VAT (ÁFA) 27%. We build tax-correct pricing, invoice fields and exportable tax reports; your accountant confirms treatment for your products.
Payments
Customers in Kecskemét expect Cards, Instant payments (AFR) and SimplePay — integrated with automatic reconciliation.
Data protection
Personal data is governed by the EU General Data Protection Regulation (GDPR). We build consent, encryption, access logs and in-region hosting where required.
24/7 availability
Kecskemét is on UTC+2 (India (IST) is 3h 30m ahead). Our team works 24/7, so your full business day and any out-of-hours incident are covered.
Delivery timeline
Discovery starts within 5 business days of a signed proposal. Most smart contract development engagements ship a first production release in 6–14 weeks, with demos every two weeks.
The Challenge
Problems we see teams struggling with
Reentrancy and logic vulnerabilities
Unaudited contracts are a common attack vector; a single flaw can lead to irreversible loss of funds.
High gas costs eroding user experience
Inefficient contract logic makes transactions expensive and discourages adoption.
Upgrade and governance risk
Poorly designed upgrade patterns create centralization risk or lock teams out of fixing bugs post-launch.
Missing audit trail before funding or listing
Exchanges, investors, and launchpads require a clean audit report before they will list or fund a token.
Integer overflow and precision errors
Fixed-point arithmetic mistakes in fee calculations or reward distributions silently misallocate funds long before anyone notices the discrepancy.
Untested edge cases in access control
Role-based permission systems that work in the happy path often have gaps that let an unintended caller trigger a privileged function.
Our Approach
What our smart contract development work covers in Kecskemét
Custom contract development
Token contracts (ERC-20, BEP-20), NFT contracts (ERC-721, ERC-1155), staking, vesting, DAO governance, and marketplace contracts.
DeFi protocol contracts
AMMs, lending/borrowing pools, yield vaults, and liquidity mining contracts with oracle-secured pricing.
Security-first development
Checks-effects-interactions patterns, reentrancy guards, access control, and pausability designed in from day one.
Gas optimization
Storage packing, batch operations, and assembly-level optimization to reduce user transaction costs.
Independent audit coordination
We prepare documentation, test coverage, and remediate findings for third-party security audits.
Formal verification support
For contracts handling significant value, mathematical proof that critical invariants hold under every possible input, not just the cases we thought to test.
Legacy contract remediation
Security review and hardening of contracts you inherited from a previous vendor or an earlier, less rigorous phase of your own project.

Our Approach
Our approach to development methodologies
Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your smart contract development project and your team in Kecskemét, Hungary.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so smart contract development priorities can change as you learn from users.
Kanban
Best for: Continuous delivery & support
A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.
Fixed-scope (Waterfall-style)
Best for: Well-specified builds
Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.
Lean MVP
Best for: New ventures
Build the smallest smart contract development release that proves demand, measure it with real users, then invest where the data points.
DevOps & CI/CD
Best for: Every project
Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.
Security-by-design (DevSecOps)
Best for: Regulated & high-value systems
Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.
