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.

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.
The Coupon Bureau is a non-profit, industry-managed organization established to modernize the coupon industry by creating a centralized data exchange for all stakeholders. The organization's primary mission is to combat coupon fraud, an issue estimated to cost the industry hundreds of millions of dollars annually, while also improving efficiency and the consumer experience.
At the heart of The Coupon Bureau's work is the development and implementation of the new Universal Coupon standard, also known as AI (8112). This new standard replaces the outdated barcode system with a more secure, serialized format for both digital and paper coupons. This allows for real-time validation of every coupon at the point of sale, effectively eliminating counterfeiting and ensuring that each coupon is used only once, as intended by the manufacturer. The platform, known as the Universal Positive Offer File, serves as this central repository for all coupon data, connecting manufacturers, retailers, and consumers in a seamless ecosystem.
The Coupon Bureau utilizes the Hedera Consensus Service (HCS) to create a tamper-proof, auditable log of every coupon's lifecycle. Each time a coupon is created, distributed, or redeemed, a transaction is recorded on the Hedera public ledger.
Wallawallet is a dedicated mobile cryptocurrency wallet designed to provide a secure and stable experience for users of the Hedera Hashgraph network. It was developed by Ledgerama with a core mission to offer robust management for HBAR, Hedera's native cryptocurrency, and Hedera Token Service (HTS) tokens. With an emphasis on security, it operates as a non-custodial solution ensuring users maintain complete control over their private keys, which are stored directly on their mobile devices. To further enhance security and minimize attack surfaces, it intentionally forgoes a web interface, focusing on a dedicated app environment for iOS and Android.
Key features of Wallawallet include seamless sending and receiving of HBAR and HTS tokens, along with integration for Ledger hardware wallets, allowing users to combine the convenience of a mobile app with the enhanced security of cold storage. It also incorporates functionality to support the Hedera ecosystem with features to help users associate tokens in preparation for airdrops, including HBAR-weighted airdrops.
