Turtlemoon
Turtle Moon is a Web3 software development and solutions company that functions as a core infrastructure builder for the Hedera ecosystem. It focuses on creating open-source tools, services, and standards that empower developers and accelerate the growth of decentralized applications on the Hedera network.
One of Turtle Moon's most significant contributions is the creation of the HCS-20 standard, a framework for issuing and managing fungible tokens using the Hedera Consensus Service (HCS). This standard provided an efficient, low-cost alternative to smart contracts for tokenization. They have also developed and open-sourced a suite of "Turtle Moon Tools" for NFT minting and management, making it easier for creators to launch projects on the network.
Beyond infrastructure, Turtle Moon is an active participant in the Hedera community, closely associated with leading the technical development for projects like HGraph Punks. By developing foundational protocols, open-sourcing their tools, and building applications, Turtle Moon plays a vital role in making the Hedera network more accessible, functional, and robust for developers and users alike.

The Coupon Bureau is a non-profit, industry-managed organization established to modernize the coupon industry by creating a centralized data exchange for all stakeholders. The organization's primary mission is to combat coupon fraud, an issue estimated to cost the industry hundreds of millions of dollars annually, while also improving efficiency and the consumer experience.
At the heart of The Coupon Bureau's work is the development and implementation of the new Universal Coupon standard, also known as AI (8112). This new standard replaces the outdated barcode system with a more secure, serialized format for both digital and paper coupons. This allows for real-time validation of every coupon at the point of sale, effectively eliminating counterfeiting and ensuring that each coupon is used only once, as intended by the manufacturer. The platform, known as the Universal Positive Offer File, serves as this central repository for all coupon data, connecting manufacturers, retailers, and consumers in a seamless ecosystem.
The Coupon Bureau utilizes the Hedera Consensus Service (HCS) to create a tamper-proof, auditable log of every coupon's lifecycle. Each time a coupon is created, distributed, or redeemed, a transaction is recorded on the Hedera public ledger.

Coinomi is a multi-asset cryptocurrency wallet launched in 2014, making it one of the oldest multi-chain wallets available. It offers a non-custodial solution giving users full control over their private keys. Coinomi is designed to support a multitude of digital assets including over 1,770 cryptocurrencies and tokens across more than 125 blockchains, including major names like Bitcoin, Ethereum, and Solana, as well as numerous altcoins and tokens.
It is available on both mobile (iOS and Android) and desktop (Windows, macOS, Linux) platforms. Key security features include strong wallet encryption with hierarchical deterministic (HD) backups featuring BIP44 algorithmic security. For privacy, Coinomi eschews know-your-customer requirements for accessing funds and records no IP associations, identity linking, or transaction tracking. Furthermore, its servers anonymize user requests by default.
The Coinomi wallet integrates built-in cryptocurrency exchange services through partnerships with platforms including Changelly and ShapeShift, allowing users to swap between different assets directly within the app. It also supports SegWit for Bitcoin and other compatible coins, enabling faster confirmations and lower transaction fees. Its services are free to use (users only pay standard network transaction fees to miners).

SEALSQ is a Swiss-based semiconductor company that specialises in developing secure microcontrollers and implementing post-quantum cryptography. A subsidiary of WISeKey, SEALSQ provides the hardware foundation for securing connected devices in a wide array of industries, including smart energy, automotive, industrial automation, and consumer electronics.
SEALSQ’s product portfolio is centred on providing end-to-end digital security. This includes the VaultIC family of secure elements, which are tamper-resistant microcontrollers offering cryptographic services for authentication and data integrity. They also develop secure ARM platforms and are pioneering post-quantum RISC-V chips to protect against future threats from quantum computing. Beyond the chips themselves, SEALSQ provides Public Key Infrastructure (PKI) and provisioning services, allowing for the secure management of a device’s digital identity throughout its lifecycle.
SEALSQ is partnered with Hedera to integrate its quantum-resistant semiconductors directly into the Hedera network's infrastructure. This partnership aims to protect the Hedera ecosystem from the emerging threat of quantum computing by "future-proofing" digital signatures and communication channels. Specifically, SEALSQ's hardware will be used in the SEALCOIN project, a tokenised platform for machine-to-machine (M2M) transactions on Hedera, which is a core component of the DePIN (Decentralised Physical Infrastructure Network) being developed by WISeKey and its subsidiaries.

MyHBARWallet is a free, open-source, and client-side interface that allows users to interact with the Hedera network. It was one of the first wallets to support HBAR, the native cryptocurrency of Hedera, and has played a significant role in the growth of the ecosystem.
Its core services is providing a user-friendly and secure wallet that allows users to create new Hedera accounts, generate and manage private keys, and send and receive HBAR and other tokens issued on the Hedera Token Service (HTS). It also supports staking, which allows users to earn rewards for helping to secure the network. A key feature of MyHBARWallet is its support for hardware wallets such as the Ledger Nano.
MyHBARWallet is a dedicated wallet for the Hedera ecosystem and utilizes all of Hedera's core services. It uses the Hedera Token Service (HTS) for all token-related functions, the Hedera Consensus Service (HCS) for any necessary transaction ordering and logging, and the Hedera File Service (HFS) for storing any relevant data. This deep integration with Hedera's fast, secure, and low-cost infrastructure makes MyHBARWallet a powerful and efficient tool for anyone looking to interact with the Hedera network.
