ZERT is a cryptocurrency Decentralized Finance (DeFi) system engineered on the principle of trustlessness, aiming to provide a secure environment where users maintain full, autonomous control over their digital assets. The platform distinguishes itself by not requiring users to rely on a third-party intermediary, aligning with the core ethos of decentralized technology. By integrating advanced security protocols and a unified solution architecture, ZERT strives to guarantee the perpetual safety and sovereignty of its users' cryptocurrency holdings. This focus on non-custodial control is central to the platform’s value proposition, ensuring that users have exclusive access to and management of their funds at all times. ZERT's system is therefore positioned to offer a single, reliable point of access for all necessary DeFi functions while rigorously maintaining user security and independence.

ZEUS is a non-custodial Bitcoin Lightning wallet and infrastructure provider that enables users to send and receive Bitcoin payments via the Lightning Network.

Participants include market makers, investment funds, and Web3-native organizations.

zkBob is a privacy-focused smart contract wallet that enables users to send and receive cryptocurrency transactions without exposing wallet contents, transaction amounts, or counterparties on-chain. It uses zero-knowledge proof technology to enable private peer-to-peer transfers, supporting USDC on Polygon, and ETH and USDC on Optimism, with USDT on Tron also indicated. The product targets individuals and organizations seeking transactional privacy for use cases such as payroll, donations, and general payments, while incorporating compliance features including daily limits, KYC options, and wallet screening. Developers can integrate zkBob functionality through an SDK and direct deposit contract, and Igor Barinov is noted as a founder of the project.

ZKcandy is an Ethereum Layer 2 blockchain constructed using ZKsync's Elastic Chain technology. The system is designed to support gaming and AI-driven entertainment applications. The architecture implements zero-knowledge proof mechanisms to enable low transaction fees and streamlined user onboarding. The platform includes a Telegram-based Game Center interface that provides mobile access and incorporates quest-and-reward mechanics for user engagement. The project is operated by iCandy Interactive, a Southeast Asian game studio, and has received support from Animoca Brands, Spartan, and Wemix. ZKcandy operates a mainnet with a native KRO token and maintains a token swap interface.

zkCloud is a cloud-based zero-knowledge proof generation service that allows developers and researchers to create ZK proofs without local hardware setup. The platform supports three proving protocols, Groth16, PLONK, and ZK-STARKs, enabling users to select the approach that best fits their proof size, speed, and trusted-setup requirements. Payments are accepted via Ethereum, zkSync, and the Lightning Network, and the service exposes an API secured by token authentication for programmatic integration. The platform targets blockchain developers and ZK newcomers alike, offering a circom-language playground, tutorials, and high-performance cloud servers described as roughly three times faster than consumer laptops. zkCloud is associated with the Intmax/InternetMaximalism project ecosystem, with a roadmap that includes ZK-Rollup infrastructure.

ZKEX is a multi-chain order book decentralized exchange (DEX) built on Layer 2 infrastructure and secured with zero-knowledge proofs. The platform supports spot trading, perpetuals, and a convert feature, with plans to expand into options and wealth management products under a V4 upgrade. Its technical differentiator is the combination of an order book model with ZK-proof security, enabling non-custodial trading across multiple chains including assets such as BTC, SOL, and TON. The platform targets both retail and more sophisticated crypto traders seeking a self-custodial alternative to centralized exchanges, with AI-assisted auto-trading tools also in development.

zkVerify is a blockchain protocol that provides universal verification of zero-knowledge proofs across multiple proving schemes and ecosystems. The protocol accepts proofs generated by frameworks including RISC Zero, Noir, Succinct, Circom, and Space and Time, and routes verified proofs to destination blockchains such as Ethereum, Arbitrum, Base, and Optimism. The system reduces on-chain verification costs and latency by performing proof verification off-chain and aggregating results for batch submission to target chains. zkVerify operates its own mainnet and includes a native token, VFY, used for protocol operations and incentives. The architecture is designed to serve ZK application developers, ZK rollups, verifiable AI systems, and provable gaming applications without requiring modifications to existing infrastructure. The protocol is part of the Horizen ecosystem.

Zogi Labs is a game development studio that creates blockchain-based games. Its primary title, Legends of Bezogia, is a cross-platform MMORPG that operates on blockchain infrastructure. The game incorporates NFT-based avatars called Bezogis, on-chain asset ownership mechanisms, and staking functionality. The platform is designed to serve both users with cryptocurrency experience and those without prior exposure to blockchain technology. The studio has partnerships with Cronos, Polygon, and ChainPlay. Additional products under development include an NFT marketplace and a cryptocurrency wallet. The studio applies production methodologies and technical standards to game development and visual design.

Zone21.com is a comparison and risk-assessment platform for Bitcoin-backed lending providers. The platform assigns numerical risk scores to centralized finance (CeFi) and decentralized finance (DeFi) lending platforms, with scores ranging from 29 (low risk) to 90 (critical risk). Risk assessments are based on custody models, rehypothecation practices, loan-to-value (LTV) ratios, and know-your-customer (KYC) requirements. The platform covers multiple lending providers and presents comparative data including interest rate ranges, liquidation thresholds, and accepted collateral types in structured tables. Users can customize comparisons between providers. The platform generates and publishes provider rankings.

Nockchain is a Layer 1 proof-of-work blockchain that integrates zero-knowledge proofs into its mining mechanism, referred to as zkPoW. The protocol combines traditional proof-of-work consensus with zero-knowledge verification. The computational foundation is built on Nock, a minimalist combinator calculus. The network launched without a pre-mine allocation. Developer tooling has been released, including NockApp and the Jock programming language to support application development. Zorp operates as a separate entity that holds the native NOCK asset, while the Nockchain protocol functions as an independent network.
