What We Build
Engineering practices built for regulated, high-stakes platforms
From blockchain and crypto infrastructure to payments, API, cloud, AI, and security — each practice is led by engineers who specialize in that domain, not generalists spread thin.
Blockchain & Cryptocurrency Development
Hurain Technologies designs and builds blockchain and cryptocurrency platforms for exchanges, fintechs, payment providers, and enterprises that need tamper-proof ledgers, tokenized assets, and programmable money. From Layer-1 and Layer-2 protocol work to token issuance, DeFi products, and enterprise blockchain integration, our engineers deliver auditable, high-throughput systems built for real transaction volume, not demo code.
Learn moreSmart Contract Development & Audit
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.
Learn moreCrypto Exchange & Wallet Development
Launching or scaling an exchange means solving matching engine performance, liquidity aggregation, custody security, and compliance simultaneously. Hurain Technologies builds centralized, hybrid, and P2P exchange platforms plus multi-currency wallet and custody infrastructure engineered for institutional-grade uptime and security.
Learn morePayment Gateway & PSP Integration Services
Every failed transaction is lost revenue and a trust hit. Hurain Technologies designs and builds payment integration layers — from single PSP connections to full payment orchestration hubs — for fintechs, digital platforms, and marketplaces that need reliable, reconcilable, multi-currency and multi-rail payment flows, including crypto on/off-ramps.
Learn moreAPI Integration & Open Banking Engineering
Banks, fintechs, and platform businesses run on APIs — and every unreliable integration becomes a partner escalation. Hurain Technologies designs, builds, and secures API ecosystems, from open banking connectivity to enterprise API management, so your partner integrations are fast to onboard, well-governed, and secure by default.
Learn moreCloud Modernization & DevOps Engineering
Legacy monoliths slow every release and every hire. Hurain Technologies modernizes applications and infrastructure for enterprises that need to move faster without breaking what already works — monolith-to-microservices migration, cloud-native re-architecture, and DevOps automation that shortens release cycles from weeks to days.
Learn moreAI Fraud Detection & Intelligent Automation
Fraud losses and manual review queues both eat margin. Hurain Technologies builds AI-driven fraud detection, transaction monitoring, and workflow automation systems for payments and fintech platforms — real-time risk scoring, anomaly detection, and automated case management that reduce loss without adding friction for good customers.
Learn moreCybersecurity, AML/KYC & Compliance Engineering
Regulated industries can't treat security as an afterthought. Hurain Technologies provides secure architecture review, API and application security engineering, and AML/KYC compliance software development for fintech, payments, and blockchain platforms handling sensitive transaction data.
Learn moreCrypto Payment Gateway & Stablecoin API Integration
Cross-border settlement through banks is slow and expensive. Hurain Technologies builds multi-chain crypto payment gateways and stablecoin APIs that let businesses accept Bitcoin, Ethereum, USDT, USDC and other digital currencies directly, settling in minutes instead of days with instant conversion and built-in AML screening.
Learn moreMPC Wallet & Crypto Custody Infrastructure Development
Traditional key management concentrates risk in one place. Hurain Technologies builds MPC (multi-party computation) custody infrastructure where private keys are split across encrypted shares, so no single device or person ever holds the complete key. Designed for exchanges, funds, and DAOs that need institutional-grade security without a single point of failure.
Learn moreCryptocurrency Wallet Development
Generic wallet apps rarely fit a specific product's compliance model or user experience needs. Hurain Technologies builds custodial, non-custodial, hybrid and smart-contract (ERC-4337) crypto wallets tailored to exchanges, Web3 platforms, gaming ecosystems and remittance products — with multi-chain support, in-app swap/staking, and full white-label branding.
Learn moreDeFi Development Services
Decentralized finance lets businesses offer trading, lending, staking and yield products without traditional intermediaries — but it also means the smart contract is the product, mistakes are public, and attackers actively probe protocols. Hurain Technologies builds DeFi platforms with security woven into the architecture from day one, drawing on real-world exploit patterns.
Learn moreCrypto Compliance, KYC/AML & Regulatory Integration
Regulatory scrutiny on crypto businesses keeps rising. Hurain Technologies integrates KYC/KYB onboarding, AML transaction monitoring, sanctions screening and FATF Travel Rule messaging into crypto exchanges, wallets and payment platforms, using a jurisdiction-aware rule engine built to work alongside licensed legal counsel.

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 custom software project.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so custom software 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 custom software 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.
Why we're different
What sets Hurain Technologies apart
Plenty of agencies can build custom software. Here is what sets us apart for clients worldwide.
Engineering depth, not a reseller
Your custom software project is designed and built by our own in-house engineers — no hidden subcontracting chain between you and the people writing code.
Built for your market, not a template
Payments, tax, language and data-protection requirements for your target market are part of the design from day one instead of retrofitted after launch.
Transparent, senior-led delivery
A named project lead, a shared backlog, fortnightly demos and direct Slack access to the engineers — you always know what is being built and why.
Cost advantage without cutting corners
Delivering from India gives clients worldwide senior engineering at a fraction of typical onshore agency rates, with the same code-review, testing and security standards.
You own everything
Source code lives in your repository from the first commit; IP, infrastructure accounts and documentation transfer to you in full.
We stay after launch
Monitoring, updates and a support SLA mean the team that built your product is the team that keeps it running.
Flexible engagement models
How we work with custom software clients worldwide
Ways to work together, depending on how your team and roadmap are set up.
