Capturiant, founded in 2022, is a Houston-based company that operates as a global environmental asset authenticator, registry, and marketplace. The company's mission is to bring efficiency, transparency, and trust to the historically opaque and fragmented environmental asset markets, including carbon credits.
The core of Capturiant's service is an integrated platform that manages the entire lifecycle of environmental assets. This includes the authentication and validation of projects that generate credits, the minting and registration of these credits on a digital registry, and a regulated exchange for trading them. By creating a transparent, private-sector-driven model with clear fee structures and robust standards, Capturiant aims to increase confidence and liquidity in the market.
Capturiant's entire platform is built on the Hedera network. The company utilizes Hedera's distributed ledger technology (DLT) to create an immutable and auditable record for every environmental asset it registers. By leveraging the Hedera Consensus Service, Capturiant ensures the integrity and transparency of all transactions, from the minting of a credit to its final retirement.

Identity Snap, developed by Tuum Technologies, is an open-source plugin that extends the functionality of MetaMask to include support for decentralized identifiers (DIDs) and verifiable credentials (VCs). This transforms MetaMask into a DID wallet, allowing users to manage their digital identities in a secure and self-sovereign manner.
The core of the Identity Snap service is its ability to create, manage, and verify DIDs and VCs directly within the MetaMask interface. It supports multiple DID methods, including did:pkh, did:key, and did:hedera, giving users a range of options for creating and controlling their digital identities. Key features include the ability to resolve DIDs to their corresponding DID documents, create and save VCs, and generate verifiable presentations (VPs) for sharing with other parties.
Identity Snap's did:hedera method allows users to anchor their digital identities on the Hedera public ledger, taking advantage of its high throughput, low fees, and robust security.
