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.

Transak is a global Web3 payment provider that builds developer-focused tools to bridge traditional finance with digital assets. The company’s core service is to enable users to seamlessly buy and sell cryptocurrencies directly within any decentralized application (dApp). This is primarily achieved through a simple, embeddable widget or API that developers can integrate into their platforms with just a few lines of code.
By handling the complex backend processes of payment processing, fraud monitoring, and regulatory compliance like KYC/AML, Transak solves a critical onboarding challenge for the Web3 ecosystem. It eliminates the need for users to leave a dApp, register on a centralized exchange, and manually transfer funds, which significantly reduces friction and improves user conversion rates. The platform supports a wide array of local payment methods across more than 150 countries, including credit/debit cards, bank transfers, and other regional options.
Transak is integrated with the Hedera network. This enables developers building on Hedera to provide their users with a direct and localized on-ramp to purchase HBAR and other Hedera-based tokens.
