In this session of the Cardano Developer Office Hours, Fergal O’Connor and Jaime Caso Onzain introduce Veridian, a new identity framework developed by the Cardano Foundation to enable secure, verifiable, and interoperable digital identity on Cardano. They explore how Veridian supports credential issuance, verification, and lifecycle management through open standards, privacy-preserving design, and a flexible architecture, including its approach to decentralized credentials, system components such as issuers, holders, verifiers, registries, and more.

In this session of the Cardano Developer Office Hours, Satya Ranjan presents Yaci DevKit, a comprehensive toolset designed to simplify and accelerate Cardano development. He covers setting up a local devnet in minutes, building and testing smart contracts and dApps, exploring integration workflows, and more.

In this session of the Cardano Developer Office Hours, the High Assurance Lab (HAL) team presents Moog and MPFS, two components designed to bring reliable, blockchain-native stress testing to Cardano and beyond. They explore how Moog leverages the Merkle Patricia Forestry smart-contract library to coordinate access to Antithesis, enabling large-scale distributed testing with on-chain auditability, traceability, secure access control, insights into the Layer Hackathon, and more.

In this session of the Cardano Developer Office Hours, Marungsha Brahma presents LW3’s Hydra-powered Digital Product Passport platform, built for the EV supply chain and aligned with upcoming European DPP requirements. He explores how LW3 leverages Cardano Layer 1 and Hydra Layer 2 to tokenize EV batteries using CIP-68, enable high-frequency, real-time operational updates, and balance privacy with transparency at industrial level, covering compliance, asset movement to Hydra, and more.

In this session of the Cardano Developer Office Hours, Santiago Carmuega from TxPipe and Darlisa Consoni from the Cardano Foundation present Tx3, a new domain-specific language for Cardano transactions. They cover how it simplifies UTxO abstraction, enables reusable interfaces for dApps, and explore associated tools like tx3app, trixs, tx3.land, and more.

In this session of the Cardano Developer Office Hours, Matthias Benkort from the Cardano Foundation presents the latest Ogmios 6.14.0 release and the 2025 Developer Ecosystem Survey. He covers new node integrations, improved query capabilities, and how the survey gathers privacy-first, multilingual feedback to shape future developer tools and ecosystem direction, and more.

Below is a well-deserved Q3 update highlighting ecosystem tooling and solutions across July, August, and September.

The past three months have been packed with releases, integrations, and upgrades that continue to strengthen Cardano’s developer tooling and infrastructure. With more than 240 pull requests merged across the Foundation’s Java ecosystem, it’s been a quarter of consistent growth, performance improvements, and developer-first innovation. Check out the highlights below to see what’s been delivered.

In this interview, Navjit Dhaliwal, founder and CEO of IAGON, explains how the platform provides decentralized storage and computing solutions that put data control back in the hands of users. Navjit shares that IAGON was initially built on Ethereum, but due to high gas fees, scalability issues, and security concerns, he chose Cardano for its research-driven approach, low costs, and strong decentralization. He highlights real-world applications with enterprises such as Hamburg Volksbank and the U.S. legal firm CloudCourt, showing how data sovereignty and secure storage make a tangible difference. Using clear analogies, he illustrates how decentralized storage turns a single vulnerable “lake” into many protected “frozen lakes” and how decentralized computing turns idle machines into a global supercomputer. Curious to see how IAGON is reshaping data management? Let’s dive in!

In this session of the Cardano Developer Office Hours, Jingles, Founder of Mesh.js, explores Wallet-as-a-Service and Transaction Sponsorship, two tools driving the next generation of Cardano dApps. He explains how Wallet-as-a-Service streamlines user onboarding and how Transaction Sponsorship removes barriers for new users. The session features real-world examples and guidance on integrating these capabilities into projects, showcasing how Mesh.js delivers seamless blockchain experiences for both developers and users.

In this session of the Cardano Developer Office Hours, Max Grützmacher and Fabian Bormann from the Cardano Foundation’s Ecosystem Engineering team lead an open discussion on the future of wallet connections. They introduce the new Wallet Connector, explaining how it enhances dApp interactions and simplifies integration. The session covers upcoming changes for developers, ongoing challenges, and how community feedback is helping shape new features and improvements across the Cardano ecosystem.
