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.

OneSpan is a Web3 platform that offers a dedicated eClosing solution designed to digitize and secure the entire lifecycle of high-value digital agreements, particularly in the mortgage and lending industries. The platform streamlines the closing process by enabling remote online notarization (RON), electronic signatures, and identity verification, all within a secure and compliant digital environment. A central component of this solution is the OneSpan eVault, a specialized repository for managing the authoritative copy of critical digital documents, such as promissory notes (eNotes).
To provide an unparalleled level of trust and auditability, OneSpan has integrated its platform with ProvenDB, a data integrity service built on the Hedera network. When a document is signed or a key milestone is reached in the eClosing process, a cryptographic fingerprint (hash) of the agreement is anchored to the Hedera public ledger. This action, facilitated by ProvenDB, creates a permanent and immutable timestamped record on the Hedera Consensus Service (HCS).
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.
