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.

AdsDax is a digital advertising platform founded in 2013 that aims to solve endemic problems in the advertising industry, such as fraud and a lack of transparency, by removing intermediaries and fostering direct, value-based connections between brands and consumers.
The core of AdsDax's service is a self-serve advertising platform that allows brands to create, buy, and sell advertising in a transparent environment. A key feature of their model is the use of incentivised experiences, where consumers are rewarded with digital assets for their engagement with advertising content. This approach, which leverages AI for campaign optimization, is designed to move beyond superficial metrics such as "likes" to drive authentic engagement and build brand loyalty. The platform supports a variety of ad formats, including interactive and video ads, and is utilised by major advertising agencies.
AdsDax uses the Hedera Consensus Service to track and verify millions of advertising events such as impressions, clicks, and conversions in real-time. Each event is recorded on the Hedera public ledger, creating an immutable and auditable trail that provides a single source of truth for advertisers and publishers. This allows for the automated and near-instantaneous settlement of payments to publishers and rewards to consumers using cryptocurrencies.

MetaStable is a decentralized finance (DeFi) platform that aims to provide a secure, private, and compliant environment for trading synthetic assets. The company is focused on leveraging advanced cryptographic techniques to solve some of the key challenges in the DeFi space, such as high slippage, impermanent loss, and regulatory uncertainty.
The core of MetaStable's service is its Automated Market Maker (AMM), which is designed to facilitate the trading of synthetic assets with minimal price impact. A key feature of the platform is its use of Zero-Knowledge Proofs (ZKPs), which allows for the verification of transactions without revealing the underlying data. This provides a high degree of privacy and confidentiality for users. The platform also includes a "DeFi Firewall," a proprietary technology that helps to ensure regulatory compliance by preventing illicit funds from entering the ecosystem.
MetaStable’s "chain-agnostic" design and support for EVM-compatible DLTs allows it be interoperable with various networks including the Hedera blockchain.
docStribute is a UK-based technology company that provides a secure and auditable solution for the distribution of sensitive documents. Founded with the goal of revolutionizing business communication, docStribute leverages distributed ledger technology to offer a more secure and efficient alternative to traditional methods such as email.
The company's core service is a document distribution platform that allows businesses to send documents of any sise with an immutable, auditable trail. When a document is sent through docStribute, a unique digital fingerprint of the document is created and recorded on a public ledger. This provides a verifiable record of when the document was sent and by whom, without storing the document itself on the blockchain. It’s designed to be user-friendly and to integrate with existing business workflows, offering features such as real-time tracking, delivery confirmation, and tamper-proof security.
docStribute's platform is built on the Hedera network. It uses the Hedera Consensus Service (HCS) to create a secure and transparent log of all document transactions.
