Slime World
Slime World is a play-to-earn (P2E) mobile game developed by NADA Digital. It’s the flagship title published under Hedera Guild Games and is available on Android and iOS. The game leverages the Hedera blockchain platform's speed, low transaction fees, and carbon-negative footprint to offer an engaging blockchain gaming experience where players collect and nurture pets called "Slimes" to protect their world and defend against the encroaching "Dark Slimes."
Players complete quests and embark on adventures to earn in-game currency called "Orichalcon" through various activities. The Orichalon can be exchanged for the Hedera Guild Games (HGG) token (formerly NADA Protocol token) a utility token based on the Hedera blockchain. It can be used within the game for upgrading player’s Slimes, purchasing items to aid in adventures, and creating unique Slime NFTs that can be collected and traded via an in-game marketplace.
Gameplay centers around a strategic tower defense-style "infinite mode" where players take on waves of enemies and a "PVP arena mode" wherein players battle one another using their owned or rented Slime NFTs.
Slime World also features mini-games such as "Super Jump" and "Road Crossing," a roulette system for rewards, enhanced social features including user profiles and global chat, and a built-in multi-staking service for HGG tokens.

Momental is a Web3 platform specializing in creating dynamic, data-driven digital collectibles, described as "Living NFTs." The company partners with sports teams, athletes, and brands to transform key moments into evolving digital assets. Unlike static NFTs, Momental’s collectibles are designed to change their appearance and metadata over time based on real-world events and data streams.
The platform is built on the Hedera network, utilizing its unique capabilities to power these dynamic assets. For example, a digital trading card of an athlete, minted as an NFT on the Hedera Token Service (HTS), can automatically update to reflect their latest game statistics, career achievements, or even video highlights. The Hedera Consensus Service (HCS) is used to ingest and provide a transparent, tamper-proof record of the real-world data feeds that trigger these updates. This ensures the authenticity and verifiable history of each change to the "Living NFT."
Through partnerships with organizations such as the SSU rugby team in South Africa, Momental provides a novel way for fans to own a piece of their favorite team's journey.

This integration allows Safe Health to provide a high level of trust and data integrity for all stakeholders. By logging events and health records on the Hedera network, Safe Health can cryptographically prove the authenticity of data in real-time while preserving patient privacy, meeting regulatory compliance standards like HIPAA, and ensuring a secure foundation for its digital health solutions.
Porini Foundation Nature Collectibles is an initiative by the Swiss-based Porini Foundation that leverages blockchain technology to create a sustainable funding model for nature conservation. The project aims to connect a global community of collectors with real-world conservation efforts, providing a transparent and direct way to support the protection of endangered species and their habitats.
At the core of the initiative are Nature Collectibles, which are unique digital representations of a species, also known as NFTs for Conservation (NFTCs). Each collectible is a "digital twin" of a real animal and is linked to a specific, on-the-ground conservation project in a protected area. These digital assets can be purchased, collected, and traded through a dedicated mobile app. One hundred percent of the proceeds from the initial sale of a Nature Collectible go directly to the conservation actors in the field, with the Porini Foundation covering all transaction fees.
The entire Nature Collectibles ecosystem is built on the Hedera network. The Hedera Token Service (HTS) is used to mint the NFTs, ensuring their uniqueness and providing a secure and transparent record of ownership. All transactions are recorded on the Hedera public ledger, allowing donors to see their contributions in real-time.

Headstarter is a decentralized fundraising platform and launchpad built exclusively for the Hedera network. Its primary purpose is to accelerate the growth of the Hedera ecosystem by providing a secure and streamlined environment for new projects to raise capital and build an initial community.
The platform operates on a tier-based system centered around its native token, $HST. To gain access to token sales, prospective investors are required to stake a certain amount of $HST, which places them into different tiers. These tiers determine the size of the allocation a user is guaranteed in an upcoming IDO, with higher amounts of staked tokens granting access to larger investment opportunities. This model creates utility and sustained demand for the $HST token while ensuring a fair and organized capital-raising process.
For projects, Headstarter provides an end-to-end solution for launching a token, handling the technical complexities of the sale and providing access to an engaged community from day one. For investors, it offers a vetted and secure venue to discover and support promising, early-stage Hedera-native projects.
