Hashlog is a data verification service that leverages the Hedera Consensus Service (HCS) to create immutable events or data logs. It enables applications and enterprises to submit messages to the HCS, where each message receives a consensus timestamp from the Hedera network, ensuring its integrity and order. This process provides a secure and transparent "proof-of-action" or "proof-of-event" capability.
Its core functionality offers a data trail for on-chain information. Once data is logged via Hashlog to the HCS, it cannot be altered or retrospectively tampered with, providing a high degree of data integrity. This is particularly useful for use cases requiring regulatory compliance, dispute resolution, or the tracking of critical operational processes. Developers integrate Hashlog systems using APIs or SDKs.
By utilizing Hedera, Hashlog provides decentralized trust, cryptographic verification, and public accessibility (if desired) for the logged information. Its applications span across multiple domains, including supply chain management for tracking goods, IoT data streams for device event verification, and legal tech for timestamping documents.

Citadel Wallet is a specialized hardware wallet designed to offer robust security and a seamless user experience for individuals interacting with the Hedera Hashgraph network. Its development was supported by HeadStarter's Builder Labs.
It features a full suite of secure storage options focused on providing secure storage and transaction capabilities for Hedera's native cryptocurrency, HBAR, as well as Hedera Token Service (HTS) tokens and non-fungible tokens (NFTs).
The Citadel Wallet device emphasizes high-grade security, incorporating features such as Common Criterial Evaluation Assurance Level 6+ (EAL8+) certified Secure Element and a secure microprocessor featuring Trust Zone technology to protect users' private keys offline.
Citadel Wallet is engineered to support the full spectrum of Hedera network services, including native staking, interaction with smart contracts, and management of various Hedera-based assets. It also features a user-friendly interface and offers both USB-C and secure Bluetooth connectivity for flexible interaction with companion applications and decentralized applications (DApps) within the Hedera ecosystem.
HashGuild is an inclusive NFT infrastructure project built on Hedera Hashgraph, serving as both a marketplace and launchpad that allows creators and collectors to mint, buy, sell, and earn rewards on Hedera-based NFTs. It emphasizes community-driven development, users can propose and vote on features, and aims to provide accessible tooling and governance-enabled services tailored to the needs of Hedera’s NFT ecosystem.
Utherverse is a metaverse platform that enables developers to build interconnected virtual worlds. Based in Vancouver, Canada, the company provides tools for creating hyper-realistic, immersive experiences for consumers and offers opportunities for businesses to market and monetize their products and services within these virtual environments.
Its core services are centered around its metaverse-as-a-service offering. This includes a proprietary Web3 browser and metaverse search engine called Xaeon, which allows users to navigate and explore the "Virtual World Web". The Utherverse ecosystem is designed to support a wide range of business verticals, from virtual retail and entertainment to education and corporate offices. A key feature is the platform's robust virtual economy, which has processed billions of transactions and is powered by the native token, UTHR.
The platform also supports the creation and trading of functional NFTs (fNFTs), which are digital assets with in-world utility. Utherverse has a direct integration with the Hedera network, which is a core component of its transition to a Web3 architecture.
HashAxis is a global NFT marketplace built on the Hedera network, designed for buying, selling, and discovering digital collectibles and non-fungible tokens (NFTs). It leverages the Hedera Token Service (HTS) to mint, manage, and trade NFTs and is supported by the HBAR foundation.
A key advantage of HashAxis is its utilization of Hedera's low and predictable transaction fees, high-speed performance (capable of 10,000 transactions per second), and carbon-negative footprint. This makes creating, buying, and selling NFTs comparatively more accessible and environmentally friendly. HashAxis also supports native Hedera functionalities including “atomic swaps” for secure peer-to-peer trading and on-chain royalty payments, which provide automatic compensation to creators for secondary sales.
HashAxis integrates “Filecoin” for decentralized NFT storage and is one of the only NFT marketplaces to offer a streamlined, no-code interface for users to engage with digital collectibles across various categories, including art, profile pictures and more.
