CryptoPort Pay

Blockchain Payments / Fintech

Seamless Crypto Payments for Global Commerce

CryptoPort Pay is a robust non-custodial crypto payment system designed for merchants who want to accept crypto without holding or managing it. It supports multiple chains and stablecoins, offering real-time conversion into fiat or other stable assets using decentralized and centralized liquidity sources.

The platform includes a lightweight merchant dashboard, payment widgets for integration with e-commerce platforms, and API support for custom checkout flows. All transactions are handled via smart contracts that ensure trustless execution and prevent custody risks.

To handle volatility, the system locks exchange rates at the time of payment using real-time oracle feeds. Merchants can choose from various settlement options - including USDC, EUR, or local currency via integrated off-ramps - making it highly flexible across jurisdictions.

Security and compliance were a top priority. We implemented address whitelisting, transaction limits, and KYC modules for enterprise clients. CryptoPort Pay is already in use by merchants across EU and LATAM regions and continues to expand its footprint globally.

NextVector helped us transform our payment flow. Our merchants now receive settlements in minutes, and the user experience is smooth and intuitive. Their team delivered beyond expectations.

AdFi Network

Web3 / NFT Infrastructure

Tokenized Ad Spaces for the Web3 Economy

AdFi Network introduces a novel concept in the advertising space — turning digital ad slots into fractionalized NFTs. Each slot can be rented for specific time blocks, enabling fine-grained targeting and transparent billing in real time.

We designed a smart contract system that manages slot ownership, rental schedules, payments, and metadata linking. The entire ad flow — from booking to payout — is handled trustlessly on-chain.

Advertisers can browse and book available slots through a React-based dApp, while publishers maintain full control of their assets. Built-in revenue streaming ensures payments are distributed continuously as ads run.

We came with an idea, and they returned with a full-stack working product. Truly impressive blockchain engineering.

EduBlock Registry

Public Sector / Blockchain

Revolutionizing Diploma Verification with Blockchain

EduBlock Registry was built in partnership with a national education authority to modernize the issuance and verification of academic diplomas using blockchain technology. The system replaces outdated paper-based processes with a fully digitized, tamper-proof smart contract registry.

Institutions can issue verifiable credentials directly on-chain, while graduates and employers can access proof of authenticity in seconds. All diploma data is hashed and stored via IPFS, ensuring transparency and immutability.

The platform complies with GDPR standards and integrates with existing government systems. EduBlock is now live across several major universities and has significantly reduced administrative overhead.

They turned a bureaucratic problem into a digital solution. The platform is reliable, secure, and has modernized how we manage academic credentials.

Security / DevTools

Automated Security Intelligence for Smart Contracts

TokenAudit is an internal smart contract audit toolkit used by security teams to automate the detection of common vulnerabilities and enforce Solidity best practices. It includes static analysis tools, customizable rule sets, and integration with CI/CD pipelines.

We developed a custom parser and rules engine capable of identifying over 50 vulnerability types, from reentrancy to gas griefing. Each flagged issue includes contextual suggestions and mitigation strategies.

TokenAudit supports both in-house reviews and client-facing reports, reducing the time and manual effort required for each engagement. It’s now used daily by one of Europe’s top blockchain audit firms.

Their audit automation tools cut our manual workload by 60%. This saved time, reduced risk, and improved our audit quality.

VaultChain

Blockchain / DeFi

Unlocking Yield Through Decentralized Vaults

VaultChain is a non-custodial DeFi platform that empowers users to deposit crypto assets and earn yield through automated strategies. The platform supports ERC-4626 vaults and features modular integrations with multiple yield protocols including Aave, Compound, and Curve.

Security and composability were core priorities. We implemented permissioned strategy modules, role-based access control, and a robust upgrade mechanism. To ensure minimal gas usage, all operations were optimized at the contract and transaction level.

VaultChain is fully integrated with real-time oracle feeds and supports live reporting through a custom-built analytics dashboard. The platform has passed third-party security audits and continues to evolve as a trusted yield-layer for DeFi enthusiasts.

NextVector delivered a robust, audit-ready solution under tight deadlines. Their team showed deep DeFi knowledge and excellent responsiveness throughout the project.

Ultra-Fast Arbitrage API for Pro Traders

CryptoBridge is a high-performance backend system for executing arbitrage strategies across centralized exchanges. Designed for hedge funds and trading bots, the API aggregates real-time data from Binance, KuCoin, MEXC, and others — with sub-second latency.

Our team built a custom rate-limiter, in-memory caching layer, and WebSocket manager to handle high-frequency requests without API bans or data loss. Order book snapshots and tick-level data are streamed continuously for optimal pricing decisions.

Security, failover handling, and scalability were essential to meet institutional requirements. CryptoBridge runs on a microservices architecture with built-in monitoring and alerting, ensuring consistent uptime and performance.

NextVector’s backend was incredibly performant and stable, even under high load. We’ve already seen significant gains using their system.
