Attestiv is a digital media validation company founded in 2018 to combat the rising threat of deepfakes and AI-generated content. Headquartered in Utah, the company provides solutions for businesses that rely on the authenticity of photos, videos, and documents, with a primary focus on the insurance, cybersecurity, and financial services industries.
The core of Attestiv's offering is its AI-powered platform that analyzes digital media to detect alterations, tampering, and generative AI content. The platform provides a "tamper score" to indicate the likelihood of manipulation and can identify specific anomalies through a forensic scan. This technology is delivered through a suite of products, including APIs and SDKs that can be integrated into existing workflows, as well as a user-friendly dashboard for manual analysis. Attestiv's solutions are designed to automate fraud detection, streamline processes like insurance claims and underwriting, and protect businesses from the reputational and financial risks associated with fake media.
Attestiv uses a distributed ledger to create a "digital fingerprint" that is recorded on the Hedera blockchain network. This allows for the immutable and verifiable timestamping of each asset, ensuring its authenticity can be validated at any point in the future.

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.
