The Hedera Wallet Snap is a powerful open-source plugin that extends the functionality of MetaMask, one of the world's most popular crypto wallets, to the Hedera network. Developed by Tuum Technologies and managed by Hashgraph, the Snap allows users and developers to interact directly with Hedera's native services without relying on a JSON-RPC relay.
At its core, the Hedera Wallet Snap transforms MetaMask into a native Hedera wallet. This provides users with a familiar interface to manage their HBAR and other Hedera-based assets. Key services include the ability to send and receive HBAR, view account information and token balances, and interact with the Hedera Token Service (HTS), Hedera Consensus Service (HCS), and Hedera Smart Contract Service (HSCS). This comprehensive functionality empowers developers to build and deploy sophisticated decentralized applications on Hedera, while providing a seamless and intuitive experience for end-users.
The integration of the Hedera Wallet Snap opens up the network to MetaMask's vast user base of over 30 million monthly active users, greatly expanding the potential reach of Hedera-based applications.

Logstash is an open-source, server-side data processing pipeline from Elastic NV. It ingests data from multiple sources simultaneously, transforms it, and then sends it to a chosen destination. It is a core component of the Elastic Stack, often used for centralizing and processing logs, metrics, and other event data.
In the context of the Hedera blockchain network, Logstash can be integrated using tools such as the logstash-output-hedera plugin. This specific Java Output Plugin is designed for the Hedera Consensus Service (HCS). It enables Logstash to send processed events or logs directly to an HCS topic. Users configure the plugin by specifying details including their HCS topic ID, an operator account ID, and the associated private key for that operator account. An optional submit key used for topic creation can also be provided, along with the target Hedera network, which can be "mainnet" or "testnet".
By using this plugin, applications can leverage Logstash's data collection and transformation capabilities to then record events onto the Hedera public ledger via HCS. This creates an immutable, verifiable, and timestamped log of the data, enhancing transparency and auditability for any system employing this integration.
Tejouri is a highly secure digital vault platform designed for the storage and management of sensitive personal and corporate documents. Launched by Moro Hub, a subsidiary of Digital DEWA (Dubai Electricity and Water Authority), Tejouri provides a trusted environment for users to safeguard their most vital information, including passports, financial records, contracts, and health data. The platform combines secure, UAE-based data centers with the transparent trust layer of a public distributed ledger.
The core of Tejouri’s advanced security model is its integration with the Hedera blockchain network. While the actual documents are stored securely off-chain, every critical action performed within the vault, such as uploading a file, sharing a document, or executing a digital signature, is recorded on the Hedera Consensus Service (HCS). This process creates an immutable and publicly verifiable audit trail. A cryptographic fingerprint (hash) of the event is logged on the Hedera ledger, providing a permanent, tamper-proof timestamp and record of the transaction.
ConsentCheq, a service by PrivacyCheq, is a consent management platform that helps businesses comply with global privacy regulations such as GDPR, CCPA, and COPPA. Since its launch in 2016, the company has focused on providing a "single source of truth" for user consent, enabling enterprises to manage and honor user privacy preferences in real-time across all their systems.
The core of ConsentCheq's service is a full-stack transparency and consent management solution. It provides tools for businesses to deliver clear privacy notices and to capture, log, and manage user consent for data collection and processing. A key feature is the "Consent Dashboard," a centralised interface where users can view and control their privacy settings for any business that uses the ConsentCheq service. The platform also offers "Consentive," an incentive-based system where consumers can be rewarded with micropayments for granting consent, which is designed to increase opt-in rates for data processing.
ConsentCheq's connection to the Hedera network is central to its "Consentive" service. The platform uses the Hedera Consensus Service (HCS) to create a high-throughput, low-cost, and auditable log of consent verification and payment events. Under privacy laws, advertising networks must verify consumer consent each time they process or track them.
Apache Log4j is an open-source, Java-based logging utility used by developers to record application events, errors, and operational data. It is a popular tool for debugging, system monitoring, and conducting audits across myriad Java platforms.
In the Hedera ecosystem, the log4j2-hedera repository offers a specific integration for Log4j 2.x and provides a custom appender that enables recording of logged events directly to the Hedera network via the Hedera Consensus Service (HCS). This allows applications to interact with HCS to submit their log entries, effectively writing them onto Hedera's distributed ledger.
The primary benefits of this integration include ensuring that logged data is distributed, secure, and transparent providing provable security. Furthermore, it guarantees the integrity and immutability of the recorded log information, as each entry is validated by Hedera’s consensus mechanism. This specialized appender provides a robust solution for applications requiring verifiable, tamper-resistant logging. This use case is distinct from how Hedera's core network software and provides additional verification.
